Frequently Asked Questions

It covers cleaning the glass, frames, and tracks, clearing drainage holes, removing mildew, and checking hinges, locks, and seals. The installer also runs a full open-and-close test and notes any faults that need a follow-up repair rather than a same-day fix.

Not necessarily a whole new window. Condensation between the panes points to a failed sealed unit, which can often be replaced without changing the frame. Condensation on the room side is usually a ventilation issue, not a glazing fault.

Dirt in the tracks is one cause, but worn or misaligned hinges are just as common. If cleaning alone has not freed the sash, the hardware likely needs adjustment and lubrication, or the hinge position may need correcting.

A stiff sash puts stress on the frame each time it is forced open, which can crack the frame around the hinge fixing. A draught that is left unchecked usually means water is also getting in, which accelerates seal and frame deterioration.

Surface cleaning is fine for routine upkeep, but it will not clear blocked drainage holes, adjust misaligned hardware, or identify a failing seal. Using the wrong products can also scratch uPVC or degrade rubber seals, making the underlying fault worse.

All three frame types are covered. Timber sashes, aluminium frames, and uPVC windows each need slightly different products and techniques, and the installer matches the approach to the material on the day.

It depends on what is agreed in the quote. Some jobs cover hanging only; others include the full hardware set. The itemised quote lists each element separately, so you can see exactly what is and is not included before work starts.

Not always. A door that sticks due to seasonal swelling or a loose hinge can often be trimmed or adjusted. A warped, cracked, or structurally damaged door usually needs replacing. The installer assesses this on site and sets out both options in the quote.

Yes. Replacement external doors must meet Part L thermal performance requirements under Building Regulations. Where the door includes glazing, FENSA certification may also apply. The installer ensures the fitting meets these requirements as part of the job.

A door that does not seal properly lets in draughts, raises heating costs, and can make the lock harder to engage over time. A frame that is already damp or soft will deteriorate further, making the eventual repair more involved and more costly.

Yes, if it is fitted correctly. A new door hung without proper perimeter sealing can still let cold air through. The installer seals the full frame perimeter on external doors, which is what eliminates the draught rather than the door alone.

If the fault is with the glass, seals, hinges, locks, or a localised frame crack, repair is usually possible. Full replacement becomes necessary when the frame is badly warped, structurally weak, or has failed across its full length. The on-site survey will tell you which applies.

Yes, in most cases. Blown double glazing is caused by a failed sealed unit. The unit is replaced with a new double-glazed pane sized to the existing frame. If the frame and hinges are still sound, only the glass unit needs attention.

No. Misting between the panes means the sealed unit has failed, not the frame. The frame, handles, and hinges are often still in good condition and can be reused once the sealed unit is swapped out.

A cracked pane is a security and safety risk and can worsen with temperature changes. A draught left unaddressed allows heat loss and moisture ingress, which can lead to frame deterioration and higher energy bills over time.

Minor cracks, movement, and fitting issues can often be repaired or adjusted in place. If the frame is split along its length, badly warped, or no longer holds the glazing securely, the installer will advise on replacement as the safer option.

The written quote lists each component, glass or sealed unit, sealant, hinges, locks, alongside labour and waste removal as separate line items. Both repair and replacement costs are set out where relevant, so you can compare before committing.

A second opinion before paying for repairs or replacement helps confirm the actual problem, check the scope of work, and reduce the risk of paying for more than is needed. It is particularly useful when comparing quotes or when a previous installer’s paperwork is unclear.

A failed seal left unchecked allows moisture into the frame cavity, which can lead to frame rot in timber windows or mould growth around the reveal. A minor draught caused by a worn weatherseal can worsen over winter and increase heating costs noticeably before it is addressed.

It can still be worthwhile. A window can look acceptable but have missing trickle vents, a failed seal not yet visible as misting, or no FENSA certificate on record. An inspection confirms the installation meets Approved Document L and Approved Document F requirements.

The installer checks frame condition, sealed unit integrity, weatherseal continuity, trickle vent presence, and hinge and lock operation. For replacement windows, the inspection also looks at whether the installation appears to meet building regulations and whether the correct paperwork exists.

If the frame is rotten, warped, or failing at the corners, full removal is usually the right call. If the frame is still sound and only the sealed unit has misted, a unit swap may be enough. The on-site survey makes that call before anything is quoted or ordered.

uPVC is generally the lower-cost material, but the final price depends on window size, style, and how many are being replaced. Timber and aluminium typically cost more, particularly for larger or non-standard openings in older properties.

Yes. Many terraced and semi-detached properties in Havering have openings that do not match standard unit sizes. The installer measures each opening on site and orders made-to-size frames where needed.

Yes, in most cases. The insert method fits the new vinyl unit from inside the existing frame opening, so the exterior finish is left completely undisturbed. The exact approach depends on the frame condition, which the installer confirms during the on-site survey.

The installer checks the frame for rot, movement, and whether it is level and plumb. The sill condition is also assessed. If the frame is not sound, a full-frame replacement is quoted alongside the insert option so you can compare both before deciding.

It can, if the problem is a failed sealed unit or poor perimeter sealing rather than frame damage. The installer identifies the cause during the survey. If the frame itself is rotten or badly out of shape, that needs addressing too, or the same issues will return.

A failed seal lets moisture into the frame over time, which can cause timber frames to rot and uPVC to warp. What starts as a straightforward insert replacement can become a full-frame job, and a more disruptive, more expensive one, if left too long.

Yes. The insert method treats each window as a self-contained job, which is why room-by-room replacement is common. There is no requirement to replace all windows at the same time.

Replacement windows in England must meet the thermal performance requirements of Part L of the Building Regulations. The installer will confirm compliance as part of the written quote, and the work should be notified to the local authority or covered by a competent person scheme certificate.

Yes. A single failing window can be replaced on its own. Many homeowners do this when one frame has deteriorated but the rest are still serviceable. There is no requirement to replace all windows at once.

Rot spreads into the surrounding structure, the sill, lintel, and internal plasterwork. What starts as a frame replacement can become a more involved repair if the surrounding timber is left damp. Catching it early keeps the scope and cost contained.

They should, provided the opening is sound and the new frame is fitted and sealed correctly. A damaged opening or worn seal can still leave gaps. The frame condition inspection before fitting is what ensures the new window performs as it should.

Replacement windows in England must meet the thermal performance requirements of Part L of the Building Regulations. The installer handles compliance as part of the fitting process, and the work is notified to the local authority where required.

A straightforward single-window replacement is typically completed in a day. If hidden damage is found in the opening, additional work may be needed, but this is identified and quoted before the new frame is ordered, not discovered mid-job.

Not always. If the frame is still sound, only the glass or sealed unit needs replacing. The installer checks the frame condition on site before recommending anything. Many uPVC frames in Havering are structurally fine and simply need the glazing unit swapped out.

No. Misting between the panes means the hermetic seal inside the unit has failed, letting moisture in. Cleaning the outside makes no difference. The sealed unit itself needs replacing, that is a straightforward job when the frame is sound.

A crack spreads under temperature change and wind pressure. It also breaks the unit’s thermal and acoustic performance immediately, raising heating costs. A cracked pane in a door or low-level position is a safety risk if it shatters.

Yes. The installer confirms the specification, single or double glazed, toughened, frosted, or a particular obscure pattern, before ordering. Correct measurement and matching the existing finish are the two steps that matter most.

Sometimes. Beads are removed to take out the old pane and inspected before refitting. If they are cracked or warped, replacements are included in the itemised quote so you know the cost before the installer starts.

Yes. Building regulations require toughened or laminated safety glass in certain locations, doors, side panels, and panes below 800 mm from floor level. The installer confirms the correct specification for the opening before any glass is ordered.

The installer checks the jambs, sill, and head on-site before quoting. If the frame is rotten, badly out of shape, or showing significant movement, a pocket fit is not appropriate and the quote will set out the full-frame alternative instead.

It will if the frame itself is sound. Misted panes are caused by a failed seal in the glazing unit, which a new double-glazed unit resolves. Draughts caused by a deteriorated frame or sill will not be fixed by the pocket fit alone.

The installer stops, documents what was found, and contacts you before proceeding. Nothing additional is done without your agreement, and the revised options are set out in writing before any further work takes place.

Usually not. The aim is to work within the existing opening. Trim stops are used to close the gap between old frame and new unit. The amount of making good depends on the window type and how the original unit was built in.

Doing several windows in one visit reduces the number of call-outs and can lower the overall cost. Some customers replace only the worst windows first. The itemised quote will show the per-window cost so you can decide how many to include.

Replacing a like-for-like window in an existing opening using a pocket fit does not typically require a building regulations application, but the installer will confirm this for your specific property type and window configuration at the survey stage.

The old window and its frame are fully removed, the opening is inspected for rot, damp and structural movement, and a completely new frame and window are fitted and sealed. It is more involved than fitting a new window into the existing frame, but it addresses problems a simpler job would leave behind.

Not necessarily. The condition of each opening determines the right approach. Where the existing frame is still sound, a pocket insert may be sufficient. Where there is rot, damp or a failing seal around the frame, full removal is the better option. The survey identifies which applies to each window.

Rot in a timber frame spreads into the surrounding structure over time. What starts as a localised sill problem can reach the lintel or internal wall, making the eventual repair significantly more involved and more expensive than addressing it at the window stage.

Removing the old frame takes more labour than leaving it in place, and any remedial work to the opening adds to the time on site. Materials cover the full frame assembly, not just the glazed unit. The itemised quote sets out each element so you can see where the cost sits.

Yes. Window installation in England is notifiable work under Building Regulations. The installer must either apply for a Building Regulations notice or self-certify through a scheme such as FENSA. The local installers we connect you with handle FENSA self-certification as part of the job.

A straightforward opening with no remedial work typically takes a few hours per window. Openings with rot, damp or structural issues take longer. Whole-house programmes are scheduled to keep disruption manageable, and the quote will indicate the expected time on site for your specific job.

Not always. A draught can come from worn weatherstripping, a hinge that has shifted, or a gap in the frame seal, all of which can be repaired without replacing the whole window. The inspection identifies the source before any replacement decision is made.

Yes. Air leaks, weak sealed units, and poor lock alignment are not visible at a glance. A structured inspection tests both appearance and operation, including a smoke test for air infiltration where needed, so hidden faults are recorded before they worsen.

A failed seal left unchecked allows moisture into the glazing unit, which cannot be reversed, the unit will need replacing rather than resealing. A draught that is ignored increases heat loss over winter. Early inspection keeps repair options open and costs lower.

Yes. For post-installation checks, the inspector verifies FENSA certification and confirms the installation meets Building Regulations performance standards. The written report records this, which is useful for landlords, conveyancing, and any future sale of the property.

The inspector checks frame condition, weatherstripping, sealed units, and hardware operation, then produces a written report. This gives landlords a clear record of window condition against their obligations around draught-proofing and habitable conditions in Havering rental properties.

Not always. Sticking is often caused by seasonal timber movement or a hinge that needs adjusting, both of which are straightforward fixes. It does indicate replacement when the frame itself has moved, the door is visibly warped, or the draught seal has failed along most of its length.

The most common causes are timber swelling from moisture, a dropped or loose hinge, or a frame that has shifted over time. In older properties, subsidence can move the frame out of square. Identifying the exact cause matters before any fix, because planing a door that is sticking due to a structural shift will not solve the problem.

Yes. A correctly fitted external door with a multi-point locking system and a continuous draught seal addresses both issues directly. If your current door rattles in the frame or lets cold air through at the edges, a new door fitted to the correct tolerances will make a measurable difference to both comfort and security.

Crumbling mortar or cracked render around the opening, damp patches on the internal reveal, staining on the lintel, and frames that no longer sit flush with the wall are all warning signs. Any of these suggest the opening itself has deteriorated, not just the glazing, and needs attention before a new window is fitted.

Water is the main reason. Once a frame seal or the surrounding render fails, moisture works into the wall structure with every rain event. Over time that causes timber decay, masonry erosion, and mould growth inside the reveal. What starts as a draughty window can become a structural repair job if left unaddressed through a full winter.

Misting between the panes means the sealed unit has failed and moisture has entered the cavity, that cannot be cleared by cleaning. The glass unit itself needs replacing. Condensation on the room-facing surface is a ventilation issue, not a sealed-unit failure, so the two are worth distinguishing before ordering.

A cracked pane is a security and safety risk, it can shatter under pressure and no longer meets the thermal performance of an intact unit. A misted sealed unit has lost its insulating gas fill, so heating costs rise the longer it is left. Neither issue resolves itself over time.

It can, if the draught is caused by a failed sealed unit or cracked pane. However, draughts more often come from worn frame seals or hardware that no longer closes tightly, issues the on-site survey will identify. If the frame seals are the cause, window maintenance may be the more direct fix.

It will fix draughts and condensation caused by failed glazing or worn seals, because the new window unit replaces those components. If the root cause is a damaged or poorly sealed outer frame, a pocket fit alone will not resolve it, the survey identifies which applies to your windows.

Repairs fix specific faults but cannot correct a frame that has warped, shrunk, or lost its seal against the opening. Once the frame itself no longer sits square or the weatherstripping channel has degraded, no amount of patching stops air movement. At that point, replacement addresses the root cause rather than the symptom.

Yes, in most cases. Draughts caused by a failed frame seal or warped sash are eliminated when the window is replaced with a correctly fitted unit. Condensation between panes means the sealed unit has failed, new double glazing resolves this. Condensation on the inside surface is a ventilation issue and replacing the window alone will not cure it.

Yes. A failed seal lets moisture into the glazing unit, which accelerates frame rot in timber windows and can cause mould around the reveal. A stiff or misaligned opener puts stress on hinges and locks over time. Small faults that cost little to fix now can require full frame replacement if left.

Yes. The survey checks weather seals, drainage channels, and frame-to-wall junctions where draughts and water ingress typically originate. Identifying those paths before cold weather arrives means any repair work can be completed while conditions are still suitable for sealant and glazing work to cure correctly.

A window can close fully yet still let air through if the seals or gaskets around the frame have perished. Compression seals flatten over time, leaving gaps the latch cannot close. Warped frames or failed mastic pointing around the outer edge cause the same problem. A window inspection can identify whether the seal or the frame itself is the issue.

Not always. If the frame is structurally sound, replacing the seals or upgrading the glazing unit alone can resolve draughts and reduce noise. Full replacement becomes necessary when the frame is warped, rotted, or too degraded to hold a new seal. An on-site survey will confirm which option is appropriate before anything is ordered.

Condensation between the panes means the sealed unit has failed and moist air has entered the cavity. New double or triple glazing with an intact hermetic seal eliminates that internal misting. Condensation on the room-facing surface is a ventilation issue, not a glazing fault, so new windows alone will not stop it.

Yes, noticeably so. Acoustic laminated glass and wider air gaps between panes reduce sound transmission significantly compared with single glazing or older sealed units. The improvement depends on the glass specification chosen, laminated acoustic glass outperforms standard double glazing for noise reduction. A window replacement consultation can match the spec to your noise level.

The most common causes are a warped or dropped frame, worn hinges, a swollen timber sash, or a locking mechanism that has shifted out of alignment. Dirt and debris in the track can also cause stiffness, but if cleaning does not free the window, the frame or hardware needs attention. Left alone, the problem usually worsens and can prevent the window from sealing properly.

If the window moves freely after cleaning the track and wiping the seals, dirt was likely the cause. If it still sticks, drags, or rattles after cleaning, there is a structural or hardware issue, a dropped hinge, a warped frame, or a failed locking point. An on-site check is the only reliable way to tell the difference.

No. Condensation on the inner surface of the glass is a ventilation issue, not a window fault. Condensation between the panes means the sealed unit has failed and the glass needs replacing, but the frame may be perfectly sound. Only condensation combined with frame rot or structural damage points toward full replacement. Glass replacement covers failed sealed units without touching the frame.

Yes. Timber frames can rot from the inside out, leaving a painted surface that looks intact while the core is soft. Aluminium and uPVC frames can crack at corners or fixings where caulk hides the gap. An on-site survey checks frame condition, glazing, and hardware before any work is quoted, so hidden issues are identified rather than painted over.

The most likely cause is a failed or shrunk external seal between the frame and the surrounding masonry. On older windows, the sealant dries out and pulls away from the wall, leaving a gap that drives rain inward under wind pressure. Resealing the perimeter is a straightforward repair, but the frame condition should be checked at the same time to rule out rot or cracking.

The clearest sign is condensation or misting trapped between the panes, which means the sealed unit has failed. Other indicators include draughts around the frame, water ingress after rain, or a visible gap between the glass and the frame. A physical inspection confirms whether the seal, the unit, or the frame itself is the source.

Yes. A sealed unit can lose its gas fill and reduce thermal performance without any visible misting. Hardware can be misaligned enough to let in draughts while still appearing to close. A physical check catches these hidden faults that a visual glance from inside the room will miss.

Sometimes. The surveyor checks the window itself, including the frame, seals, and glazing. If the evidence points to condensation caused by poor ventilation rather than a seal failure, that will be noted. The written findings will say what was and was not found at the window itself.

Yes. The inspection checks weather seal compression, frame alignment, and hardware closure to assess how well each window performs against cold air infiltration. Where seals are worn or the frame has moved, the written quote will set out what repair or replacement would restore a proper draught-resistant close.

The most common causes are a perished or compressed weatherseal around the sash, a misaligned frame that no longer closes flush, or a failed edge seal on the glazing unit. Each has a different fix: seal replacement, frame adjustment, or a new glazing unit. Identifying the exact source matters, because treating the wrong one leaves the draught in place.

Stiff windows are usually caused by hinge wear, a dropped sash that is binding against the frame, or a locking mechanism that has shifted out of alignment. uPVC frames can also distort slightly over time, changing how the sash sits. Most of these are mechanical adjustments or hardware replacements rather than full window jobs.

Handles, locks, and hinges are wear parts and fail independently of the frame or glass. A handle that spins without engaging usually means a broken spindle or gearbox inside the mechanism. A hinge that sags or grinds typically needs replacing rather than lubricating. These are standalone repairs that do not require disturbing the glazing or frame.

Cold weather causes frames and sashes to contract, which widens any existing gap between the sash and the frame. Weatherseals that are compressed or perished year-round become noticeably worse in winter. The fix is usually seal replacement or a sash realignment, both of which are straightforward repairs rather than full replacements.

You likely need a full replacement when the frame itself is warped, rotten, or cracked beyond repair. Persistent draughts, condensation between panes, and difficulty opening or locking the window all point the same way. A surface repair can fix minor seal or hardware faults, but a failing frame cannot be patched long-term.

No, the deciding factor is how far the rot has spread. Surface rot on a painted sill or a small section of frame can often be cut back and repaired. Once rot reaches the structural joints, the frame loses rigidity and a full replacement is the safer, longer-lasting fix. An on-site survey will confirm which applies to your windows.

Yes, provided the new frame is correctly fitted and sealed to the surrounding masonry. Draughts and water ingress on old wooden windows usually come from shrunken frames, failed putty, or gaps at the reveal. A new frame with fresh perimeter sealing and weather-stripped sashes eliminates those paths. The on-site survey checks the reveal condition before fitting begins.

A correctly fitted wooden frame with perimeter mastic sealing and weather-stripped sashes eliminates the gaps that cause draughts and water ingress. The reveal is prepared before the new frame goes in, so the seal is made to the masonry, not just around the frame itself.

Properly primed, painted, and sealed timber performs well in wet conditions. The risk comes when the paint film breaks down and water sits against bare wood. New frames arrive factory-primed and are finished on site; maintaining the paint coat every few years is what keeps them watertight long term.

Most door hanging jobs come in at £650-£1,200, varying by door type, frame condition, and whether new hardware is supplied. An on-site survey before any work is ordered gives you an itemised written quote covering materials, labour, and waste removal so there are no surprises.

It depends on what is agreed at quote stage. Hardware such as handles, locks, and letterplates can be included or supplied separately by you. The itemised written quote sets out exactly what is and is not covered before anything is ordered.

Yes, trimming and planing to achieve a proper fit is part of the installation. The on-site survey records the exact opening dimensions beforehand, so the door is prepared to fit the frame rather than adjusted after hanging.

Any fittings included in the job are listed in the itemised written quote before work begins. If you supply your own hardware, that is noted too. Nothing is added to the cost without your agreement at quote stage.

The itemised written quote covers all labour for frame removal, new frame installation, sealing, making good the reveals, and waste removal. There are no separate call-out or disposal charges added afterwards. The quote is provided after an on-site survey, so the labour figure reflects the actual job rather than a generic estimate.

Full-frame work involves removing and disposing of the entire existing frame, preparing the bare opening, and making good the surrounding finishes, all of which add labour time and materials. A pocket fit reuses the existing frame, so the scope is narrower. The extra cost of full-frame replacement reflects the additional work, not a premium on the window itself.

Yes. Quotes are provided per job, so a single window is quoted on its own merits. An installer will visit, assess that window, and provide a written itemised quote covering glass, frame, labour, and waste removal for that opening alone.

Yes. The free itemised written quote covers glass supply, labour and waste removal as separate line items, so you can see exactly what each element costs. Nothing is bundled in a way that obscures the breakdown.

No. The written quote is issued after the on-site survey, so measurements and frame condition are already confirmed before any figure is given. Materials, labour and waste removal are all itemised, and the quote sets out repair-or-replace options before anything is ordered.

Yes, a free itemised written quote is provided after the on-site survey, before any glass is ordered or work begins. The quote covers glass, labour and waste removal, with repair-or-replace options set out clearly so you can decide without any pressure.

Most pocket window installations in Havering come in at £500-£1,200, depending on window size, glazing specification, and frame condition. The free itemised quote covers glass, frames, labour, and waste removal, so there are no hidden additions on the day.

The main factors are window size, glazing type (double or triple, acoustic, or obscure glass), the number of windows being done, and whether any frame repairs are needed before the insert can be fitted. All of these are itemised in the written quote after the on-site survey.

Yes, a free itemised written quote is provided after an on-site survey, before anything is ordered. If the survey uncovers damage that changes the scope, that is discussed with you and requoted, no work proceeds without your sign-off on the revised figure.

Government energy-efficiency schemes such as the Great British Insulation Scheme may cover window upgrades for eligible households, typically based on EPC rating and household income. Check current eligibility on the GOV.UK website, as scheme availability and criteria change. Most homeowners fund window installation privately.

Replacing several windows in one visit costs less per window than single replacements. Setup, travel, and waste removal are shared across the job, which reduces the overhead on each unit. If multiple windows are near the end of their life, grouping them into one visit is the more cost-effective approach. See £495-£930 for typical ranges.

The main factors are window size, whether a pocket insert or full-frame replacement is needed, glazing specification, and the number of units. Access difficulty and any structural repairs to the opening also affect the total. Typical costs run at £495-£930, and the itemised written quote breaks down glass, frames, labour, and waste removal separately.

The free itemised written quote covers glass, frames, labour, and waste removal, and sets out repair-or-replace options based on what the on-site survey finds. If the survey identifies structural or rot issues, these are included in the quote before anything is ordered, so there are no unexpected additions once work begins.

Pricing is not typically tied to season for vinyl window replacement. Demand can be lower in winter, which may mean shorter lead times, but there is no standard seasonal discount. The main cost drivers are window size, specification, and whether structural repairs are needed, not the time of year.

Inspection costs typically come in at around £95, depending on the number of windows and the complexity of the assessment. An itemised written quote is provided before any work proceeds, so you know the full cost upfront.

The main factors are the number of windows being assessed, the property type, and whether compliance documentation needs to be reviewed. Access difficulty, such as upper-floor windows, can also affect the time required. The quote is itemised so each element is visible before you commit.

The inspection fee covers the assessment itself. If faults or missing compliance paperwork are found, any follow-on repair or replacement work is quoted separately with repair-or-replace options set out before anything is ordered. There are no hidden charges added to the inspection cost itself.

Most window installation projects come in at £495-£930, depending on the number of windows, frame material, glazing specification, and whether a pocket insert or full-frame replacement is needed. The free itemised quote covers glass, frames, labour, and waste removal so there are no hidden additions.

The main factors are the number of windows, frame material (uPVC, timber, or aluminium), glazing type (double, triple, or acoustic laminate), and whether the existing frame can be retained for a pocket insert or needs full removal. Difficult access, non-standard opening sizes, and decorative glazing bars also add to the total.

Yes. The free itemised written quote explicitly covers waste removal and disposal of old frames, so you will not face a separate skip or collection charge. Labour, materials, and clearance are all listed as separate line items, making it straightforward to see exactly what is included.

Yes. A local installer visits first to survey the frames and glazing, then provides a free itemised written quote covering glass, frames, labour, and waste removal. Nothing is ordered until you have reviewed and accepted that quote, so the figure you agree is the figure you pay.

Most window maintenance jobs come in at around £95, depending on the number of windows, the work identified, and whether any parts are needed. You receive a free itemised written quote after the on-site survey, covering glass, frames, labour, and waste removal, before anything is ordered or started.

The main factors are the number of windows, the type of frame material, the condition of the seals and hardware, and whether any glazing units or locking parts need replacing. The written quote itemises each element, glass, frames, labour, and waste removal, so you can see exactly what you are paying for.

Costs vary by the number of windows and the complexity of access. Most inspections come in at around £95. The quote is free, itemised, and provided in writing after the on-site survey, so you know the full cost before committing to anything.

The main factors are the number of windows, their type (casement, sash, tilt-and-turn), and access difficulty such as upper floors or restricted openings. Checking several windows in one visit is more cost-effective than separate appointments, and the written quote breaks down each window individually.

Most window repairs come in at £95-£180, depending on what has failed and whether it is glass, hardware, or frame work. A free itemised written quote is provided after an on-site survey, so you see the exact cost broken down by materials, labour, and waste removal before any work begins.

The main factors are the type of fault (glass unit, seal, hardware, or frame), the size and glazing specification of the window, and whether parts need ordering. Access also plays a role, a ground-floor casement costs less to work on than a large first-floor unit. The written quote itemises each element so nothing is bundled or hidden.

A single window replacement typically comes in at £495-£930, depending on size, frame material, and whether a pocket insert or full-frame removal is needed. Waste removal and labour are included in the itemised quote you receive before any work starts.

Whole-house costs vary with the number of windows, frame material, glazing specification, and access. A local installer surveys every window first, then provides a single itemised written quote covering glass, frames, labour, and waste removal so you can see the full figure before committing.

Frame material is the biggest factor, aluminium and timber cost more than uPVC. Window size, glazing type (double or triple), and whether a full-frame removal or pocket insert is needed all affect the price. Difficult access, such as upper-floor windows without scaffold, can also add to the total.

Yes. A local installer visits first to assess frame condition, glazing, and hardware. You then receive a free itemised written quote covering glass, frames, labour, and waste removal, with repair-or-replace options set out clearly. Nothing is ordered until you approve it.

The itemised written quote covers glass, frames, labour, and waste removal before work begins, so there are no surprises at that stage. If the survey reveals unexpected structural damage behind the frame, something only visible once the old window is out, the installer will discuss any additional cost with you before proceeding.

Some homeowners in Havering may qualify for energy-efficiency grants through government schemes such as the Great British Insulation Scheme, depending on property type and household income. It is worth checking current eligibility on the GOV.UK website before booking, as schemes and criteria change regularly.

The main factors are window size, whether a pocket insert or full-frame replacement is needed, glazing specification, and the condition of the reveal. Most replacements come in at £900-£1,400, with the itemised written quote breaking down materials, labour, and waste removal before anything is ordered.

Yes. A local installer visits the property to record frame condition, glazing, and hardware before any figure is given. The written quote that follows is itemised, glass, frames, labour, and waste removal, and sets out repair-or-replace options so you can see exactly what you are agreeing to.

Yes, both internal and external doors are covered. The process is the same: an on-site survey first, then a written quote covering the specific door type, frame condition, hardware, and labour before any work is scheduled.

In most cases, yes. A local installer visits the property first to measure the opening and assess the frame before quoting. Non-standard sizes, unusual frame materials, or awkward access are all recorded at that stage so the right approach is planned in advance.

Yes, but the frame condition needs assessing first. Older properties often have frames that are out of square or have settled unevenly, which affects how a new door is hung and sealed. The on-site survey records this before the quote, so the right fitting method is planned from the start.

Exposed positions can put more stress on hinges, seals, and locking points, so hardware specification matters. The on-site survey takes the property’s position and exposure into account, and the quote reflects any additional requirements for the specific location.

It depends on the condition of your existing frames. If the frames are structurally sound, square, and free of rot or water damage, a pocket fit slots the new window inside them. If the frames are warped, rotten, or the surrounding structure is compromised, full-frame replacement is the right call. An on-site survey will confirm which applies to your property.

Soft or spongy timber, visible rot, gaps between the frame and the wall, and persistent draughts despite intact glazing all point to frame failure. If the frame has moved out of square, new glass alone will not seal correctly. A local installer can assess the frame condition during an on-site survey before any work is ordered.

Full-frame replacement needs a window installer with direct experience of structural openings, not a general handyman. The work involves assessing lintel and sill condition, correctly fixing and weatherproofing the new frame, and ensuring the installation meets Building Regulations where applicable. An unqualified fit risks water ingress, frame movement, and compliance issues.

Not necessarily. Windows with structurally sound, undamaged frames may be better suited to a pocket fit, which is less invasive and faster. The on-site survey assesses each window individually and the written quote sets out which approach suits each opening, so you are not pushed into full-frame work where it is not needed.

Many do, particularly properties built before the 1970s with original timber frames that have never been replaced. Decades of weather exposure, repeated repainting, and settlement movement often leave frames rotten or out of square. An on-site survey will confirm the actual condition rather than assuming based on age alone.

Yes, provided the frame is structurally intact and not warped, rotted or cracked. An on-site survey checks the frame before any glass is measured or ordered. If the frame is damaged, a full replacement may be the more practical route.

In most cases, yes. The on-site survey records the existing glazing specification, double or triple glazing, toughened, laminated, obscure or low-emissivity, so the replacement unit matches what was there before. Unusual heritage or decorative glass may need a specialist supplier.

Yes, for most cases. Misting between panes means the sealed unit has failed, and replacing the glass unit restores clarity and thermal performance. If the frame is also damaged or the window is very old, the on-site survey will flag whether a full replacement makes more sense.

The on-site survey records your existing glazing type and frame condition, so the replacement unit is specified to match. Where building regulations or planning conditions apply, for example in a conservation area, the installer will note this before ordering.

A pocket fit works when the existing frame is structurally sound, square, and free from rot or water damage. An on-site survey checks frame condition, glazing, and hardware before anything is ordered, so you get a clear answer before committing.

Yes, the old frame stays in place and carries the new window, so it must be solid, square, and free from rot. If the survey finds damage, a full-frame replacement is the safer option, and the itemised quote will set out both routes.

Pocket fitting suits most standard casement, sash, and tilt-and-turn frames, provided the outer frame is sound and square. Unusual shapes, very old timber frames with significant decay, or non-standard openings may require a full-frame approach instead. The on-site survey confirms which method applies.

Yes, older homes with solid, square timber frames in good condition are well suited to pocket installation. The method preserves the original frame profile, which matters in period properties where the external appearance is important. The survey confirms whether the frame meets the condition required.

Pocket installation is often the practical choice in terraced houses precisely because it avoids external scaffolding for most ground and first-floor windows. The outer frame stays in place, so there is no need to work on the brickwork from outside. The survey will flag any access issues specific to your property.

Cosmetic fading alone rarely justifies replacement. However, if the frames are chalking, the hardware is stiff, or the sealed units are clouding, those are signs the window is approaching the end of its useful life. An on-site survey can confirm whether the condition warrants replacement or whether maintenance will extend the lifespan.

Yes, if the existing frame is structurally sound and square. This is called a pocket or insert installation, the new window drops into the old frame, preserving the surrounding finish. If the frame is rotted, out of square, or too narrow after the insert, a full-frame replacement is needed instead. A survey confirms which approach suits your opening.

Yes. Vinyl replacement windows are regularly fitted into timber-framed openings. The key check is that the timber framing is dry, solid, and free of rot before the new window is secured to it. Fixing into compromised timber undermines the seal and the fixing strength, so the frame condition is assessed during the on-site survey.

Yes, with a pocket installation. The new window is inserted into the existing frame from inside, so exterior cladding or siding stays undisturbed. This only works if the existing frame is structurally sound. Where the frame needs replacing entirely, the exterior finish around the opening will need to be removed and reinstated.

Vinyl is not permitted in listed buildings or most conservation areas, where timber or approved materials are required by planning conditions. For standard post-war and modern homes it is a practical choice. An on-site survey confirms whether the property has any planning restrictions before a window type is specified.

Yes, provided the opening is structurally sound. Vinyl frames with multi-chamber profiles and double or triple glazing significantly reduce air infiltration compared with aged single-glazed or early double-glazed units. The survey checks the opening condition first, since fitting a new window into a compromised reveal will not deliver the draught reduction expected.

Yes. Vinyl does not rot, corrode, or absorb moisture, which suits the wet winters and variable temperatures common across Greater London. The material expands and contracts with temperature, so correct installation with appropriate fixings and flexible sealant is important to maintain the weathertight seal through seasonal movement.

Yes. Post-war and suburban homes in areas like Havering typically have standard rectangular openings that suit vinyl replacement well. These properties are rarely subject to conservation restrictions, so vinyl is usually permitted. The on-site survey confirms the frame and opening condition before specifying whether a pocket or full-frame approach is appropriate.

Yes, if they were recently fitted without a FENSA certificate or building regulations sign-off. Visually sound windows can still have poor draught seals, incorrect ironmongery, or missing compliance paperwork that only a close inspection reveals. Catching those gaps early is far simpler than addressing them after a sale or dispute.

Yes. A local installer visits the property to assess frame condition, glazing, and hardware independently. If the advice you received was incorrect, the inspection will show what the actual fault is and what the appropriate fix looks like, giving you a clear basis to act on.

It suits both. Older properties often have frames showing rot, failed putty, or single glazing that no longer meets thermal standards. Recently fitted windows may have compliance gaps or installation faults. The inspection approach is the same: a physical assessment of each component followed by a written report.

The core checks are the same, but flats may have lease or freeholder restrictions on window types, and post-war properties often have non-standard frame sizes. The on-site survey accounts for those factors when recording frame condition and glazing, so the written options reflect what is actually feasible for the property.

Yes. The on-site survey records the exact dimensions and condition of each opening before anything is manufactured or ordered. Whether a pocket insert or full-frame replacement is specified, the frames are sized to the measured opening, not to a standard catalogue size.

The itemised quote sets out both pocket-insert and full-frame options with their respective costs, so you can weigh performance against budget before committing. Frame material, glazing specification, and style are matched to the property during the survey, not chosen from a fixed package.

Yes. Timber-effect profiles, flush casements, and heritage-style glazing bars replicate the appearance of original windows while meeting current thermal standards. The survey notes the existing style so the replacement matches the character of the property. Listed buildings may need additional consent, which the installer will flag at survey stage.

Style suitability is assessed during the on-site survey, where frame profiles, opening configurations, and finish options are matched to the property. Casement, sash, tilt-and-turn, and bay configurations are all available, so the replacement can follow the original design intent rather than imposing a generic look.

Older terraces often have openings that are out of square or slightly irregular, which is why the on-site survey records exact dimensions rather than relying on standard sizes. Frames can be manufactured to non-standard dimensions, and pocket inserts can accommodate minor irregularities without disturbing the surrounding masonry.

Exposed frontages benefit from frames with reinforced mullions and multi-point locking hardware, which resist wind pressure and reduce rattling. The glazing specification, particularly the spacer bar width and gas fill, also affects thermal performance in exposed positions. The survey flags orientation and exposure so the spec reflects the actual site conditions.

Window maintenance covers cleaning frames, tracks, and glass; lubricating hinges, handles, and locking points; resealing gaps between the frame and the wall; and adjusting hardware that has shifted. It also includes identifying early-stage damage, failed seals, hairline frame cracks, or soft timber, before those faults become larger repairs.

Yes. The survey and any subsequent work covers the full window: frame condition, glazing, seals, and hardware. The written quote sets out each element separately, so frame repairs and glass work are not bundled together, you can see what each part of the job involves.

Intermittent faults usually mean the underlying cause is still present, frames that swell and ease with temperature changes, or hardware that is close to failing. A window that frees itself is not fixed. Having it checked while it is accessible avoids a more urgent call-out when it seizes completely.

The highest-impact tasks are resealing the external frame-to-wall joint, replacing worn brush or rubber seals around opening sashes, and adjusting locking points so the sash compresses the seal fully when closed. These three together account for most draught problems. Checking them before November means any parts needed can be sourced without urgency.

Yes. A single window is a perfectly reasonable reason to book an on-site survey. The surveyor visits, assesses that window fully, and provides a written quote covering the repair or replacement options before any work is ordered.

Yes. Multiple windows can be assessed in a single visit, which is more efficient than booking separate appointments. The written quote will itemise each window individually, so you can see the condition and options for each one before deciding what to proceed with.

Yes. A whole-property survey covers every window in one visit. Each frame, sealed unit, seal, and hardware set is recorded separately, and the written quote sets out the findings and options window by window so you can prioritise which to address first.

Window faults do not settle on their own. A failed seal continues to lose performance, a draught gap widens as the frame moves with temperature changes, and water ingress causes progressive damage to the surrounding structure. An early inspection is less disruptive and less costly than waiting.

The core checks are the same, but the surveyor adapts to the property type. Post-war frames are more likely to show timber decay or steel corrosion. Flats may have communal or fire-rated glazing considerations. Bungalows often have larger openings with heavier sashes. The on-site survey accounts for these differences before any quote is issued.

A repair is usually possible when the frame is structurally sound and only the glass, seal, or hardware has failed. If the frame itself is warped, rotten, or cracked beyond a localised section, replacement is the more practical route. An on-site survey checks frame condition, glazing, and hardware before any decision is made, so you get a clear answer specific to your window.

Minor surface damage, small cracks, and localised discolouration on uPVC frames can often be repaired. Structural damage, such as a snapped corner weld, a badly warped sash, or a frame that no longer holds its shape, usually means the frame needs replacing rather than patching. An on-site check establishes which category your damage falls into.

All of those faults fall within the scope of a window repair visit. Sealed glazing units, perished weatherseals, worn hinges, failed locking mechanisms, and localised frame damage are each addressed as separate line items. The on-site survey identifies every fault present so the quote covers the full picture rather than just the most visible issue.

Minor faults rarely stay minor. A small seal failure lets moisture into the frame, which accelerates rot or uPVC distortion and can turn a straightforward glass swap into a full frame replacement. A failed lock left unaddressed is also a security gap. Addressing the fault early almost always costs less than waiting for secondary damage to develop.

It depends on the frame material and condition. Timber frames in period properties can often be repaired, re-sealed, and rehung to extend their life significantly. Where frames have been poorly maintained for many years, replacement with a sympathetic timber or slim-profile unit may be the more practical long-term answer. A window inspection establishes the condition of each frame before any decision is made.

Yes, but the frame material and style need to match the property’s character and any planning or conservation requirements. Timber or slim-profile aluminium windows are often more appropriate than standard uPVC for pre-1920s homes. If your property is listed or in a conservation area, permitted development rules may restrict your options.

Newer homes built from the 1980s onwards typically have uPVC or aluminium frames that can be replaced on a like-for-like basis without planning complications. Upgrading to double or triple glazing improves thermal performance noticeably. A pocket insert is often sufficient, avoiding the cost and disruption of a full-frame removal.

Interwar and post-war semi-detached and terraced houses across Havering, particularly in Romford, Hornchurch, and Upminster, often still have original single-glazed timber frames that are past repair. Properties built before the 1980s that have never had their windows updated are the most common candidates for full replacement rather than patching.

Yes. There is no requirement to replace all windows at once. A single failed frame can be swapped out while the rest remain in place. The new window is made to match the existing profile and finish so it sits consistently with its neighbours.

New wooden frames are made to match the existing profile, moulding detail, and finish of your property. The on-site survey records the current frame dimensions and style so the replacement is ordered to the correct specification rather than a standard off-the-shelf size.

Yes. Timber frames are the original material in most pre-1970s houses and can be replaced like-for-like without altering the character of the property. Where a property is listed or in a conservation area, timber is often the only material planning will accept. The survey confirms what profile and finish is needed.

Yes. Replacing windows one at a time is straightforward. Each job is quoted and completed independently, so you can spread the work across months or years without any obligation to do everything at once.

No. Only the failed window needs replacing. There is no structural or regulatory reason to change windows that are still performing. Each window is assessed individually at the on-site survey, and the quote covers only the work that is actually needed.

The on-site survey records the existing profile, moulding, and finish so the replacement is made to match. Timber frames can be supplied in the same section size and painted to the same colour as the originals, keeping the appearance consistent with the rest of the property.

Yes. Timber is the original material in most Victorian, Edwardian, and interwar homes across Havering, and a like-for-like replacement preserves the character of the property. In conservation areas or listed buildings, timber frames are often the only material that planning consent will allow.

For a straightforward internal door a competent handyman can suffice, but external doors involve weatherproofing, security hardware, and frame integrity that benefit from a dedicated installer. A poor external door fit can leave gaps that affect draught resistance and security, so the stakes are higher than a simple internal swap.

Repair is usually the right call if the door sticks due to humidity swelling or a loose hinge. Replacement makes more sense when the frame is rotten, the door is warped beyond planing, or the seal and security no longer meet a reasonable standard. The on-site survey sets out both options with costs before you decide.

Replacing all windows in one visit usually reduces the overall cost compared with separate jobs, because mobilisation, survey, and waste-removal costs are shared across the project. If several windows need attention, it is worth asking for a combined quote to see the difference before deciding.

Replace the ones showing rot, damage, or seal failure first, those are causing ongoing harm. Windows that are still performing adequately can wait. A combined quote will show whether doing them all at once makes financial sense, but there is no obligation to replace windows that do not yet need it.

Neither is universally better, the right choice depends on the condition of the existing frames. Full-frame replacement is the correct option when frames are rotten, out of square, or the surrounding structure is damaged, because a pocket fit over a failing frame will not hold or seal correctly. Where frames are sound, a pocket fit is quicker and less disruptive. See pocket window installation for a direct comparison.

Yes, when the existing frames have suffered weather damage. Rain and wind exposure over many years causes timber to rot and frames to move, meaning a pocket fit would be built on a compromised base. Full-frame replacement removes the damaged material entirely and starts from a sound, sealed opening.

No, if the frame is sound, only the glass unit needs replacing. A local installer will check the frame condition on-site before anything is ordered. Replacing just the glazed unit costs considerably less than a full window replacement and causes far less disruption.

If the frame is in good condition, replacing only the glass unit is usually the more cost-effective option. The on-site survey checks frame integrity, and the written quote sets out both options with costs so you can compare them directly before committing. See full window replacement if the frame is the issue.

For a sealed double-glazed unit, a DIY fix is not practical, the unit is factory-sealed and must be ordered to exact measurements. Incorrect fitting can crack the glass or compromise the seal immediately. A correctly measured and fitted unit from a vetted installer avoids a costly repeat job.

No, if the frame is warped, rotted or has failed seals due to water ingress, replacing only the glass will not solve the underlying problem. The on-site survey checks frame condition specifically for this, and the written quote will set out whether a full frame replacement is needed. See window repair options for frame-related issues.

Generally yes, because the outer frame stays in place, cutting labour time and removing the need to make good brickwork or internal plaster. The itemised written quote covers both options side by side, so you can compare the actual figures for your specific windows before deciding.

Doing all windows in one visit usually reduces the overall cost, as mobilisation, survey, and waste-removal charges are spread across the job. The free itemised quote can cover a single window or the whole house, so you can see the difference before committing.

A full-frame replacement is the better choice when the outer frame is rotten, out of square, or poorly sealed to the brickwork. The on-site survey checks exactly this, and the written quote sets out both options, pocket insert and full-frame, with costs, so you can make an informed decision.

Pocket fitting requires accurate measurement, correct shimming to keep the frame square, and proper sealing to prevent water ingress. A poorly fitted window can cause draughts, leaks, and condensation within months. Using a trained installer reduces that risk significantly.

A handyman can remove a sash, but correct pocket installation requires precise measurement, levelling, and weatherproof sealing to manufacturer tolerances. An incorrectly fitted window can void the product warranty and lead to water damage. A window installer with the right tools and experience is the safer choice.

Repeated repairs on the same unit, failed seals, stiff hardware, persistent draughts, usually cost more over time than a single replacement. If the sealed unit has misted and the frame is sound, glass replacement may suffice. If the frame itself is warped or degraded, replacement is the more durable fix.

An incorrectly fitted window can void the manufacturer’s warranty, allow water ingress, and leave gaps that undermine thermal performance. Window installation also needs to comply with Building Regulations Part L on energy efficiency. A surveyed, correctly fitted installation avoids these risks and ensures the window performs as specified from day one.

Yes, because an inspection often shows that only one component has failed rather than the whole window. Replacing a misted glazing unit or worn seal costs considerably less than a full window replacement. The inspection gives you an honest basis for that decision before anything is ordered. See repair options

The inspection identifies the specific fault first. If only the glazing unit or seal has failed, a repair is usually sufficient. Full replacement is recommended only when the frame itself is structurally compromised or when the window no longer meets current thermal standards. The written quote sets out both options clearly.

No. Misting means the sealed unit has failed, but the frame is often still sound. In that case, only the glass unit needs replacing, not the entire window. An inspection confirms whether the frame can accept a new unit, which is a significantly lower cost than a full replacement. See glass replacement

The deciding factor is frame condition. If the frame is structurally sound and the hardware still operates correctly, a seal replacement or glazing unit swap is usually sufficient. Rot, warping, cracked profiles, or frames that have moved out of square mean a full replacement will hold up better long-term. The itemised written quote sets out both options so you can compare costs before committing.

Repair works when the frame is intact and the fault is isolated, a failed seal, broken handle, or single cracked pane. Replacement makes more sense when frames are rotten, draughty along their full length, or the glazing is single-pane. The on-site survey records frame condition and glazing before the quote, so you get a clear repair-or-replace recommendation in writing.

Cleaning the glass and wiping down frames is straightforward and worth doing regularly. What DIY cleaning cannot do is identify a failing seal, adjust a dropped hinge, or reseal a gap between the frame and the wall. If the window is stiff, draughty, or misting between the panes, a proper inspection is needed rather than a clean.

Simple lubrication or a track clean is within a competent handyman’s range. Resealing frames, replacing failed glazing units, or adjusting multi-point locking systems needs someone who works specifically with windows and understands how frame, glass, and hardware interact. Getting it wrong can void any existing warranty on the unit.

Maintenance is the right starting point if the frame is structurally sound and the glazing unit is intact. If the frame is rotten, cracked beyond repair, or the window no longer meets current thermal or security standards, replacement is the more cost-effective route. The on-site survey identifies which option applies and the written quote sets out both. Window replacement covers full swap-outs when maintenance is not enough.

Not necessarily. Draughts often come from worn or compressed weather seals, a misaligned sash, or a loose frame rather than a failed unit. An inspection identifies the exact source, so you only replace what has actually failed. A full replacement is only recommended when the frame itself is beyond repair.

Yes. A DIY fix applied to the wrong part of the window wastes time and can mask a more serious fault. Knowing the exact cause first means any repair targets the actual problem. The survey is free to quote, so you lose nothing by finding out what you are dealing with before touching anything.

Yes, in most cases the sealed unit can be swapped out while the frame stays in place. This works when the frame is undamaged and the existing rebate accepts a replacement unit. If the frame is warped or the seal failure has caused frame rot, a full replacement becomes necessary. A site visit confirms which option applies before anything is ordered.

Misting means the hermetic seal between the panes has failed, and the only lasting fix is replacing the sealed unit. The frame itself rarely needs changing unless it has been damaged by the moisture. Replacing just the glass unit is quicker and less disruptive than a full window replacement, and it restores thermal performance fully.

DIY attempts on sealed units, frame welds, or multipoint locking mechanisms can complicate a later repair. Sealant applied over a failed edge seal, for example, traps moisture and masks the true extent of the damage. Adjusting hinges without the correct tools can strip fixings. A professional assessment first confirms whether the fault is one you can safely address yourself.

Many stuck windows need only a hinge adjustment or a sash realignment rather than any part replacement. If the frame has warped or the hardware has worn past its adjustment range, a repair becomes necessary. An on-site check takes only a few minutes to distinguish between the two, and the quote reflects whichever applies.

Surface weathering and localised paint or coating failure on external frames can be repaired. If sustained rain exposure has caused the frame substrate to rot, crack structurally, or lose its shape, replacement is the more durable option. An on-site survey checks the depth of any damage to confirm which route is appropriate for your specific frames.

Misting between panes means the sealed unit has failed, not the frame, so a glass unit swap is usually enough. Replacement makes more sense when the frame is also damaged, the window is single-glazed, or the unit has failed repeatedly. An on-site survey will confirm which option suits your window before anything is ordered.

uPVC is the most common choice because it is low-maintenance, thermally efficient, and cost-effective. However, it is not always the right fit, aluminium suits contemporary or large-span designs, and timber is often required for period properties or conservation areas. The best material depends on your home’s style, planning constraints, and budget.

uPVC suits most homes, it needs little upkeep and performs well thermally. Aluminium handles larger frames and suits modern aesthetics, though it costs more. Timber is the right choice for period homes or where planning rules require it, but it needs periodic repainting. Your installer will confirm what is appropriate after the on-site survey.

Ask each firm for an itemised written quote that separates glass, frames, labour, and waste removal. Check that they carry public liability insurance and that the installation will be FENSA-registered, which is a legal requirement for replacement windows in England. Comparing like-for-like specifications, same frame material and glazing, makes quotes easier to assess.

For windows that have been repeatedly exposed to driving rain, the frame itself often deteriorates beyond what repair can fix, particularly timber frames with rot at the sill or corners. Replacement gives you a fully sealed, thermally efficient unit with current hardware. Repair is worth considering only when the frame is structurally sound and the fault is limited to glazing or seals. A window inspection can confirm which applies.

The key test is whether the frame joints are still solid. Soft or spongy timber around the corners, gaps where the frame has pulled away from the wall, or glass that has shifted in the rebate all point to structural failure that repair cannot fix. A local installer visits the property to assess frame condition before any recommendation is made. Window repair covers jobs where the frame is still structurally sound.

Replacement is the better option when the frame joints have failed, rot has reached the structural timber, or the glazing seal has broken down repeatedly. Repair suits localised surface damage on an otherwise sound frame. The written quote sets out both options with costs so you can compare them before committing.

For a straightforward like-for-like swap a competent joiner can do the work, but the fitting must meet Building Regulations for thermal performance and weather resistance. A specialist installer will specify the correct glazing unit, seal the frame to the required standard, and provide documentation, a handyman typically cannot. Incorrect fitting can void any product warranty.

Timber needs repainting periodically to stay weathertight, while uPVC or composite frames need less upkeep. For a period property where appearance matters, timber is still a sound choice if you are prepared to maintain the paint coat. For a modern property with no character restrictions, a lower-maintenance material may suit better. Vinyl window replacement is worth comparing if maintenance is the priority.

A single internal door typically takes two to four hours. An external door with new hardware and frame work can take a full day. Work is scheduled to keep time on site short, and the survey beforehand means materials and preparation are sorted before the installer arrives.

Waste removal is included in the itemised written quote, so you know before work starts whether old door and frame disposal is covered. Nothing is left for you to arrange unless that is specifically agreed and reflected in the price.

There will be some dust from trimming and any frame work, but it is contained to the immediate area. Work is scheduled to keep time on site short, and the installer tidies as they go so the disruption is brief and localised.

The finish depends on the condition of the existing frame and whether any making-good is needed around the architrave. The on-site survey identifies any gaps or damage beforehand, so the quote covers the work needed to leave a clean, flush finish rather than discovering it mid-job.

Yes, someone needs to be present for an external door installation for security reasons and to confirm the finished result. For internal doors the same applies, as the installer will need access to the room and may need decisions made about hardware or finish during the job.

Flats may have communal area restrictions or managing agent requirements, and post-war properties can have non-standard frame dimensions or steel lintels that affect installation. The on-site survey identifies these factors before quoting, so the method and materials are matched to the building rather than a standard approach.

The installer removes the entire existing frame, sill, and any fixings back to the bare opening. The opening is checked for damage, then the new frame is fitted, levelled, and secured. Gaps are filled and sealed, glazing is installed or confirmed, and internal and external finishes are made good before the installer leaves.

A single full-frame replacement typically takes half a day to a full day, depending on window size, access, and the condition of the opening. Multiple windows on the same property are usually scheduled consecutively to keep total time on site as short as possible.

There will be some dust and noise during frame removal, and the opening will be exposed briefly. Work is scheduled to keep time on site short, and the installer will protect internal surfaces where practical. Most single-window jobs are completed within one working day, leaving the room usable by evening.

Yes. Making good the reveals, sealing around the new frame, and removing old frames and waste are included in the scope of a full-frame installation. The itemised written quote sets out exactly what is covered, so there are no surprises about what is and is not included on the day.

In most cases, yes. Once the old frame is out, the installer can see the full condition of the lintel, sill, and surrounding masonry. Minor repairs to the opening are typically handled on the same visit. More significant structural issues may need a separate specialist, but the installer will flag these clearly before proceeding.

Removing the old frame can disturb the internal plaster reveal and external render or pointing around the opening. The installer makes good these areas as part of the job, filling, sealing, and finishing the reveals so the new frame sits cleanly. The scope of this making-good work is confirmed in the written quote before installation begins.

Once the on-site survey is done and the unit is ordered, most standard glass replacements are completed in a single visit. Lead times vary depending on glass type and supplier availability, but work is scheduled to keep time on site as short as possible.

First, a local installer visits to survey the frame and record the glazing specification. A free itemised written quote follows. Once approved, the replacement unit is ordered to size, fitted on a scheduled visit, and the old glass is removed and taken away.

Yes. Removal of the old glass unit is included, and the work area is left clear before the installer leaves. The written quote covers waste removal, so there are no separate disposal charges.

Usually yes, provided the frame is structurally sound. The glazing bead or putty is removed, the old unit taken out, and the new unit fitted and resealed, all without disturbing the surrounding frame. The on-site survey confirms whether the frame can support this approach before any work is scheduled.

Only the sashes, glazing, and internal hardware are removed. The outer frame stays in the opening, which is why the surrounding brickwork, plaster, and trim are largely undisturbed. This is what keeps the work faster and less invasive than a full-frame replacement.

A local installer visits the property before any work is quoted, checking frame condition, glazing, and hardware in person. Most hidden issues are caught at that stage. Occasionally, removing the sash reveals concealed rot, and the installer will discuss options with you before proceeding.

If damage is found once the sash is out, the installer will stop and explain what they have found before continuing. You can then decide whether to proceed with a repair to the frame or switch to a full-frame installation, nothing is ordered or fitted without your agreement.

In most pocket installations, the interior and exterior trim stays in place, which is one of the main advantages of the method. If the trim needs to be moved to allow a clean fit or proper sealing, the installer will flag this during the survey before work begins.

Because the outer frame and most trim remain undisturbed, there is minimal making-good needed. Any gaps between the new frame and existing trim are sealed neatly. The on-site survey identifies in advance whether any trim will need adjustment, so there are no surprises on the day.

Pocket installation is less disruptive than a full-frame replacement because brickwork and plaster are not disturbed. Work is scheduled to keep time on site short. Each window opening is exposed only briefly, and dust and debris are kept to a minimum by retaining the outer frame.

A single window typically takes a few hours; a whole house can usually be completed in one or two days. Work is scheduled to keep on-site time short, and the installer will give you a clear timeframe when the quote is confirmed.

Less than a full-frame replacement, because brickwork and plaster are not touched. Dust and debris are mainly limited to the immediate area around each window. Furniture near the window is worth moving or covering beforehand, and waste removal is included in the quoted price.

For a pocket installation, the outside cladding or trim usually stays in place. For a full-frame replacement, the exterior trim around the opening is removed to allow the new frame to be set and flashed correctly. The installer confirms which approach applies after surveying the opening, so there are no surprises on the day.

A pocket installation causes minimal disturbance to surrounding finishes. Full-frame work requires removing exterior trim, which may leave small areas needing touch-up. Internally, the reveal plaster can chip if the old frame is tight. Installers work carefully to limit this, but minor making-good around the reveal is a normal part of full-frame replacement.

A single window is typically completed in a few hours, leaving the opening exposed for a short period. Dust and debris are contained to the immediate work area, and old frames and glass are removed from site. Work is scheduled to keep time on site short, so most households can carry on normally during the job.

A single pocket replacement typically takes two to four hours. A full-frame swap runs longer due to trim removal and resealing. Replacing several windows in one visit is more efficient because setup, access, and waste removal are shared across the job, so the time per window falls when multiple units are done together.

Yes. A local installer visits the property before any work is ordered to record frame condition, glazing, and the surrounding structure. This on-site survey identifies rot, damp, or structural issues in the opening so they can be factored into the quote rather than discovered mid-installation.

Yes, for most replacements. The installer works from both sides to remove the old unit, set the new frame, and seal the perimeter correctly. Ground-floor windows are straightforward. Upper-floor work may require ladders or scaffolding on the outside, which is confirmed during the survey so access arrangements are agreed in advance.

The existing frame must be checked for rot, structural integrity, and whether it sits square in the opening. The reveal depth also needs to confirm the new unit will fit without reducing the glass area unacceptably. These checks happen during the on-site survey, before the replacement window is measured and ordered.

An inspection covers frame condition, glazing integrity, seal performance, opening hardware, and drainage channels. The inspector also checks whether the installation meets building regulations requirements. Each element is assessed separately so you know exactly what is working, what is failing, and what needs attention.

Photos can flag obvious misting or visible damage, but they cannot confirm seal failure, frame movement, draught paths, or hardware wear. An on-site visit is needed to record frame condition, glazing and hardware accurately before any repair or replacement decision is made.

A local installer visits the property to carry out the survey, and work is scheduled to keep time on site short. Contact us to arrange a convenient slot and we will confirm availability for your area.

Yes. Each component is assessed individually: seals, frame condition, glazing units, and opening hardware are all checked separately. The findings identify which element is at fault so any repair or replacement work targets the actual cause rather than the whole window by default.

Yes. The findings are set out in a written quote that itemises each issue and presents repair-or-replace options in plain terms. Each element, glass, frames, labour, and removal, is listed separately so you can see exactly what is needed and why before making any decision.

Yes. The on-site survey records frame condition, glazing integrity, seal performance, and hardware function as separate items. Each is assessed individually so the written findings tell you the condition of every component, not just a general pass or fail for the window as a whole.

The key checks are frame integrity for signs of rot or water ingress, seal condition around the glazing rebate, drainage channel blockages, and the performance of weather seals on opening sashes. Draughts and damp patches near the frame are also noted, as both indicate where water or air is bypassing the window.

The installer removes the existing window, prepares the opening, and fits the new frame, either as a pocket insert into the existing outer frame or as a full-frame replacement down to the structural reveal. The unit is levelled, sealed, and hardware is tested. Internal and external pointing is finished before the installer leaves.

A single window typically takes two to four hours; a full house of eight to twelve windows is usually completed in one to two days. Work is scheduled to keep time on site short. The exact programme is confirmed at the survey stage once the number and type of windows are known.

Some dust and debris around the reveal is unavoidable, but the installer protects internal surfaces and clears waste before leaving. External mastic pointing is finished as part of the installation. Minor plaster making-good around the internal reveal may be needed after fitting, and this is noted in the quote where applicable.

The process starts with an on-site survey, which is arranged after your initial enquiry. Lead times from survey to installation depend on the frame material and glazing specification chosen, as bespoke sizes require manufacturing time. The installer confirms the installation date once the quote is accepted and materials are ordered.

Bungalows and chalet bungalows often have low-level or dormer windows that require working at different heights and sometimes in restricted roof spaces. Access is straightforward for ground-floor openings, but dormer or roof-light replacements may need additional staging. The survey identifies any access constraints so the installation programme accounts for them.

Yes. A maintenance visit covers the full window: frame condition, track and channel cleanliness, seal integrity, and the operation of every hinge, handle, and locking point. Any faults found are recorded and included in the written quote so you can see exactly what needs attention and what can wait.

Yes. The on-site survey identifies what needs cleaning, what needs adjusting, and what needs repairing, and all of that is set out in the written quote before work begins. Where parts are needed, a second visit may be required, but straightforward cleaning and hardware adjustments are typically completed in the same appointment.

A local installer visits the property to carry out the on-site survey before any quote is issued. Availability depends on current demand in your area, so the best step is to get in touch and confirm a date. Work is then scheduled to keep time on site as short as possible.

Maintenance work is generally low-disruption, most tasks involve hand tools and no structural changes. Work is scheduled to keep time on site short. Any waste from replaced seals, glazing units, or hardware is removed as part of the job, so there is no clearing up left for you.

A visit should cover frame condition (including corners and fixings), the glazing unit for seal failure or cracking, track and channel cleanliness, hinge and handle operation, locking point alignment, and the external seal between the frame and the wall. Each of these is recorded during the on-site survey before the quote is issued.

Yes. Seal integrity and the operation of all moving parts, hinges, handles, and locking mechanisms, are checked as standard. Failed seals cause draughts and water ingress; worn moving parts affect security and ease of use. Both are included in the survey and itemised in the written quote.

Once a year is a practical minimum, ideally in early autumn before cold weather sets in. Wet winters accelerate seal degradation and cause timber frames to swell, so catching small faults before the cold spell means they can be fixed without urgency. A second light check in spring picks up any damage the winter left behind.

An inspection covers the frame condition, glazing integrity, weather seals, hardware operation, and how the sash or casement opens and closes. The surveyor also checks for draughts, water ingress points, and any movement or distortion in the frame. The aim is a complete picture, not just the fault you already noticed.

Yes. The on-site survey records frame condition, glazing integrity, weather seals, and hardware operation as standard. The surveyor checks how the window opens, closes, and locks, looking for misalignment, stiffness, or gaps. Every element is assessed before any repair or replacement option is put to you.

Yes. The survey goes beyond the fault you reported. The surveyor checks for early-stage seal failure, frame movement, and hardware wear that has not yet caused a noticeable problem. Catching these early avoids a minor issue becoming a more disruptive repair later.

No. The inspection and the repair are separate steps. After the survey you receive a written quote with options, and you decide whether and when to proceed. Nothing is ordered or started until you have agreed to the work in writing.

The survey checks weather seals, frame joints, and glazing edges for water ingress paths, and assesses how well the window closes against wind pressure. In exposed positions, the surveyor also looks for frame movement and any gaps where driving rain can track behind the frame into the wall.

Hardware repairs and adjustments are typically completed in a single visit. Sealed unit replacements require the new glass to be measured and manufactured first, which adds a short lead time before the fitting appointment. Work is scheduled to keep time on site as short as possible, and you are told the expected timeline at the quote stage.

The process starts with an on-site survey to record exactly what has failed. A free written quote follows, itemising glass, frame work, hardware, labour, and waste removal. Once agreed, the repair is carried out in a scheduled visit, replacing or adjusting only the components identified, leaving the rest of the window undisturbed.

Work is scheduled to complete the repair in a single visit wherever possible, so the window is not left open or unglazed overnight. Where a glazing unit must be ordered, the existing frame is left intact and functional until the new unit arrives. If a lock or handle is being replaced, the window remains closeable throughout.

Waste removal is included in the itemised quote, so old glass, packaging, and removed hardware are taken away as part of the job. The work area is left clean before the installer leaves. You will not be left to dispose of a broken sealed unit or old frame sections yourself.

The installer removes the old window, checks the surrounding frame or reveal for damage, then fits the new unit and seals it. For a full-frame job, the outer frame is removed first; for a pocket insert, the new frame sits inside the existing one. The area is cleaned up and the window is tested for operation and security before the installer leaves.

A single window typically takes one to two hours. A full-house replacement is usually completed in one or two days, depending on the number of windows and access. Work is scheduled to keep time on site short, so your home is not left open for longer than necessary.

Removing old frames produces dust and debris around the window reveal. Installers work room by room to limit the spread, and old frames and glass are taken away as part of the job. Internal decoration close to the window may need minor touching up once the new frame is in place.

The installer will refit internal trims and seal around the new frame. Minor plaster repairs to the reveal are typically included, but full redecoration, repainting walls or replacing skirting, falls outside the standard scope. Your itemised quote will set out exactly what making-good is covered before work starts.

Someone needs to be present at the start to give access and confirm the scope. After that, you do not need to stay in the room while work is under way. The installer will ask you to check each completed window before moving on, so being available at the end of the job is worthwhile.

In a terraced house, access to upper floors may require a ladder or short scaffold section, which the installer arranges. In a flat, you will need to confirm with your freeholder or managing agent that replacement is permitted and check whether the lease specifies a frame style or material. The installer can advise on FENSA registration, which applies regardless of property type.

The itemised written quote covers glass, frames, labour, and waste removal. On the day, the old frame is taken out, the reveal is checked and prepared, the new frame is fitted and sealed, and all debris is cleared from site. Nothing is left for you to arrange separately.

A single window typically takes half a day to a full day, depending on frame size and reveal condition. Work is scheduled to keep time on site short, so your room is not left open for longer than necessary. Multiple windows on the same property are batched to reduce the number of visits.

The on-site survey checks the reveal and surrounding masonry before any work is ordered. Once the old frame is removed, the installer inspects the opening again. If additional damage is found at that stage, it is assessed and discussed with you before the new frame goes in.

The opening is exposed only for the time needed to fit and seal the new frame. Work is scheduled to minimise on-site time, and waste removal is included in the quote, so there is no rubble or old frames left for you to deal with.

No. We arrange a local installer to carry out the survey, quote, and fitting. The installer is independent and works directly in Havering. Our role is to take your enquiry, match you with the right person, and make sure the process runs without gaps.

There is no charge for the on-site survey or the written quote. The installer visits, records what is needed, and returns an itemised price. You only proceed if the quote suits you.

The installer checks the existing frame on site. If the frame is structurally sound, a pocket insert, fitting a new double-glazed unit into the existing frame, may be enough. If the frame is rotten, warped, or poorly sealed, a full-frame replacement is set out as the better option.

The quote lists glass, frames, labour, and removal of the old frames as separate line items. If making good around the frame is needed, that is included too. Nothing is bundled into a single figure that is hard to check.

A failed seal lets moisture into the unit, and that condensation will not clear. Over time the frame around it can soften or rot, turning a straightforward unit swap into a full-frame replacement. Draughts also raise heating costs every month the window stays unrepaired.

Not always. A draught can come from worn seals, a misaligned hinge, or a frame that no longer closes flush. If the frame itself is warped or the glazing unit has failed, replacement is usually the better option. The on-site survey identifies the cause before any quote is issued.

A pocket insert fits a new glazed unit into the existing outer frame, suitable when the frame is still level and structurally sound. A full-frame replacement removes everything back to the masonry, which is needed when the frame is rotten, warped, or hiding damp. The written quote sets out which method suits your windows and why.

The itemised written quote is based on an on-site survey, not a phone estimate, so frame condition and glazing type are recorded before the price is set. Nothing is ordered or removed until you have agreed the written scope and price.

A window that is already letting in water or showing soft timber around the frame will allow damp to spread into the surrounding structure. What starts as a straightforward frame replacement can become a larger repair involving masonry or internal plasterwork if the work is left too long.

Yes. Replacement windows in domestic properties must meet Building Regulations for thermal performance and, where required, ventilation via trickle vents. The installer certifies completed work to FENSA standards, which covers Building Regulations compliance and provides a certificate for your records.

Any coverage terms are set out before work begins. Raise any concerns as soon as they appear, a door that drops, sticks, or fails to seal properly after fitting should be reported promptly so the cause can be assessed and rectified without delay.

Our partners are vetted independent local installers. Insurance details are confirmed at the point of connecting you with a partner, so you can ask for confirmation before any work starts. Never allow installation work to proceed without the installer confirming their public liability cover.

Guarantee terms vary by partner and are confirmed at quote stage. Ask for any guarantee to be stated in writing alongside the itemised quote so you have a clear record of what is covered and for how long before you commit.

The written itemised quote is provided before any work is ordered, covering glass, frames, labour, and waste removal. If the installer uncovers unexpected damage once the old frame is out, they will explain the additional scope and cost before continuing. Nothing is added to the bill without your agreement first.

Our partners are vetted independent local installers. Any warranty or guarantee terms will be set out clearly before work begins. Ask the installer to confirm the coverage period and what it includes in writing as part of the quote process, so you know exactly what protection you have after installation.

The installers we connect customers with are vetted independent local partners. You should confirm that the installer carries public liability insurance before work starts, a straightforward question to ask when reviewing the written quote. Any reputable window fitter will be able to confirm this without hesitation.

In England, replacement windows must comply with Building Regulations Part L (energy efficiency) and Part K (safety glazing where applicable). An installer registered with a competent person scheme such as FENSA or Certass can self-certify the work and issue a certificate. Keep this document, you will need it when selling the property.

Yes. A local installer measures the aperture on-site before anything is ordered, so the unit is cut to the exact dimensions of your frame. Ordering from a site measurement, rather than a customer-supplied figure, avoids sizing errors.

The on-site survey records the existing glazing specification before anything is ordered, which is the main safeguard against ordering errors. The written quote confirms the glass type, so you can check it matches your requirements before approving the order.

If the glass breaks due to a manufacturing defect in the sealed unit, that is a matter for the supplier’s product warranty. Impact damage is a separate issue. Ask the installer at the survey stage what warranty the specific unit carries, as this varies by glass type and supplier.

Yes. Once fitted, the installer checks that the window opens, closes, and locks correctly, that seals are continuous, and that there are no gaps allowing air or water ingress. Any adjustment needed is made before the installer leaves the property.

Contact the installer as soon as you notice the problem. A post-installation window inspection can identify whether the issue is a fitting fault or a separate cause. Fitting faults should be rectified by the installer at no additional cost, confirm this in writing when you accept the quote.

Coverage depends on the warranty terms set out by the installer and the window manufacturer. Ask for these in writing before work starts. The free itemised quote is the right moment to confirm what is covered and for how long, so you are not left uncertain after the job is done.

If the survey misses concealed damage that only becomes visible once the old frame is removed, the installer will stop and discuss the options with you before proceeding. The itemised written quote sets out repair-or-replace options in advance, so you understand the scope before anything is ordered. No additional work is carried out without your agreement.

Correct sealing depends on the frame being square, the fixing being secure, and the perimeter being fully weatherproofed. The on-site survey checks the opening before the window is ordered, so the unit is sized and specified to fit correctly. A window fitted to a surveyed, sound opening will seal as the manufacturer intends.

Vinyl frames typically last 20 to 30 years before the material begins to chalk or distort noticeably. The sealed glazing units may need replacing sooner if the edge seal fails. Longevity depends on the quality of the original installation and how well the perimeter seal is maintained over time.

Yes. The inspection checks whether the installation meets building regulations requirements, including thermal performance and ventilation standards. If compliance documentation such as a FENSA certificate is missing, the inspection will flag that gap so you can take the appropriate steps to resolve it.

Yes. Replacement windows in England must meet building regulations for thermal performance and, in some cases, ventilation. Approval is usually handled through a competent person scheme such as FENSA, which issues a certificate confirming compliance. Without that certificate, you may face difficulties when selling the property.

Yes, in almost all cases. New windows must meet Part L thermal performance standards and, where applicable, Part F ventilation requirements. A FENSA-registered installer self-certifies compliance and issues a certificate. If your installer did not provide one, an inspection can identify whether the installation meets the required standards.

Common reasons include verifying a recent installation before the installer’s liability period ends, resolving a dispute with a previous contractor, or checking compliance before a property sale. An independent assessment gives you a factual record of condition and compliance that is not tied to any sales interest.

Full-frame removal carries a small risk of disturbing the surrounding plaster or render, which is why the survey assesses the reveal condition beforehand. Where damage is likely, it is flagged in the quote. Pocket installations leave the outer frame intact, which significantly reduces any impact on internal decoration or external brickwork.

Because frames are measured on-site before ordering, sizing errors are rare. The itemised written quote confirms the specification, dimensions, profile, glazing type, and finish, so you can verify every detail before manufacture begins. Any discrepancy between what was agreed and what arrives is resolved before installation proceeds.

Our partners are vetted independent local installers; ask your installer at survey stage to confirm the product guarantee period and any workmanship warranty they provide in writing. Reputable installers typically offer a manufacturer-backed guarantee on sealed units and a separate workmanship warranty on the fitting itself.

Yes. Window installation in England must comply with Building Regulations Part L and Part N. A FENSA or CERTASS certificate is issued by the registered installer as evidence of compliance, and a copy is lodged with the local authority. You will need this certificate when you sell the property.

The on-site survey records frame condition, glazing, and hardware before any quote is issued. The written quote then sets out repair-or-replace options, so the underlying cause is addressed rather than masked. Nothing is ordered or started until you have agreed to the scope in writing.

Yes, abrasive pads or solvent-based cleaners can scratch glass and strip protective coatings from uPVC or aluminium frames. Timber frames can swell or crack if soaked with water. Using the correct tools and products for each frame material is part of what a proper maintenance visit covers.

Yes. After the survey you receive a free itemised written quote that sets out the fault found, the repair or replacement options, and the costs for glass, frames, labour, and waste removal. The repair-or-replace decision is laid out before anything is ordered, so you are not pressured into a choice on the day.

Yes. When the same fault appears across several windows, the survey can identify whether the cause is a systematic installation issue rather than isolated wear. The written findings give you a clear record to use if you need to raise the matter with a previous installer.

The written report sets out what was found and what was not found, so you have a clear record either way. If the fault is intermittent or environmental, the surveyor will note that and explain what further observation would help. You will not be left with a blank report and no direction.

A local installer visits first to assess the frame, glazing, and hardware, then provides a free itemised written quote. That quote sets out both the repair option and, where relevant, the replacement option, with costs for each. Nothing is ordered until you have agreed to a specific scope in writing, so there are no surprise escalations on the day.

If the same fault recurs, contact the partner who carried out the work directly. The on-site survey is designed to identify the root cause rather than just the symptom, so a recurring fault after a correct repair is uncommon. Any warranty terms are confirmed in writing at the quote stage, specific to the components replaced.

The on-site survey records frame condition, glazing, and hardware together, not just the reported symptom. If a failed seal has allowed water ingress that has softened the frame behind it, both are noted in the quote. Fixing only the visible damage without addressing the cause is the most common reason a repair fails prematurely.

Yes. The installer tests every lock, handle, and hinge before leaving, and the sealed unit is fully set in its frame. Modern replacement windows meet current security standards, including multi-point locking on casement and tilt-and-turn designs. You should not need to take any additional steps to secure the property after the installer leaves.

Contact the installer as soon as you notice a problem, whether that is a draught, a faulty lock, or a seal failure. Reputable installers will return to inspect and rectify issues covered under the product or installation guarantee. Getting any concerns in writing promptly helps establish a clear record if a formal warranty claim is needed.

Most replacement windows carry a manufacturer’s guarantee on the sealed units and frames, typically covering seal failure and hardware faults. Installation workmanship is separately guaranteed by the installer. Ask for both guarantees in writing before you sign anything, and confirm whether they are insurance-backed so they remain valid if the company ceases trading.

The installer assesses the reveal and surrounding timber once the old frame is out. If additional damage is found, you are told what it is and what is needed to address it before the new frame is fitted. Nothing extra is carried out without your agreement.

Any post-installation issue should be raised directly with the installing partner. The on-site survey and itemised written quote are designed to identify and address potential problems before fitting, reducing the likelihood of issues arising after the job is complete. Ask your installer about their specific workmanship terms at the quoting stage.
