We schedule a survey of each opening, provide an itemised quote covering all frames and glazing, and coordinate fitting around your programme. ## What the installation process actually involves Understanding each stage helps you know what to expect, and whether repair or replacement is the right call for your windows. The first question is whether replacement is needed at all. A draught caused by a worn seal or a misaligned hinge can sometimes be fixed without removing the frame. Where the frame itself is warped, rotten, or the sealed glazing unit has failed, repair tends to cost more than it saves. The on-site survey records frame condition, glazing integrity, and hardware before any decision is made, so the written quote can set out both options with separate costs. Once replacement is agreed, the method depends on the outer frame. If it is still level, plumb, and structurally sound, a pocket insert fits the new double-glazed unit into the existing opening using shims and weatherproofing sealant, leaving the surrounding plaster and exterior finish undisturbed. Where the frame is compromised, a full-frame replacement strips the opening back to the masonry, checks for hidden damp or rot, and installs a new uPVC, timber, or aluminium frame with energy-rated glazing and trickle vents where Building Regulations require them. After fitting, the installer checks that the window opens, closes, and locks correctly, and that the perimeter seal is airtight with no gaps at the reveals. Replacement windows in domestic properties require FENSA certification or local authority Building Control approval, the installer handles this as part of the job. Old frames and glazing are removed from site, and any making good around the internal reveals is completed before the installer leaves.

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. ### How much will window installation cost? 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. ### Does the quote include taking the old windows out and clearing everything away? 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. ### Are these windows made to fit my opening properly? 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. ### Will the suggested windows suit my house and budget? 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. ### What happens during window installation? 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. ### How quickly can the work be booked in? 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. ### Will fitting new windows damage my plaster, brickwork or decoration? 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.
