Your home is assessed and an itemised quote follows before any work." canonical: "https://www.haveringdoubleglazing.co.uk/services/window-replacement" lastmod: "2026-11-09T10:21:11.122Z" --- # Window Replacement in Havering ![A modern white house with a grey conservatory, surrounded by a lush green garden and paved steps on a sunny day.](https://utmost-ibex-736.convex.cloud/api/storage/9150f479-2266-42ed-ac6e-4f0a3de23ec0) Old frames out, new windows fitted and certified, draughts, misting, and rattling frames sorted for good. - **Free On-Site Survey**: An on-site visit comes before any quote is given. - **Itemised Written Quote**: Glass, frames, labour, and removal listed separately. - **FENSA Certification Included**: Paperwork is handled as part of the job. - **Repair or Replace Options**: Both options are set out before anything is ordered. ## Where rushed or cheap window replacement falls short The frame opening tells you more than the frame itself, skipping that check is where problems start. - **Skipped Opening Check**: Fitting a new frame over a damp or damaged reveal traps moisture and causes the new window to fail early. **Inspect Before Fitting**: The installer checks the reveal for damp and rot before the new unit is measured in and ordered. - **Wrong Frame Size**: Standard off-the-shelf units rarely fit older Havering properties, leaving gaps that let in draughts and water. **Made-to-Size Frames**: Older homes in the borough are measured individually so the replacement frame fits the actual opening. - **No Compliance Paperwork**: Replacement windows without FENSA registration or a Building Regulations certificate can block a property sale. **Self-Certification Handled**: The installer manages FENSA self-certification so the Part L compliance paperwork is ready when the job is done. - **Repair Sold as Replacement**: Replacing a whole window when only the sealed unit has failed adds unnecessary cost and disruption. **Honest Repair-or-Replace Call**: The written quote sets out both options, sealed unit swap or full-frame replacement, before anything is ordered. ## What window replacement covers From a single misted pane to a full run of frames across the property, the scope depends on what the survey finds. - **uPVC Frame Replacement**: Old frames are removed and replaced with new uPVC units, fitted level and sealed on all faces for draught-free performance. - **Timber Frame Replacement**: Rotted or warped timber frames are taken out and replaced with new timber units, sized to the original opening. - **Aluminium Frame Replacement**: Aluminium replacements suit properties where a slimmer sightline or a more contemporary finish is needed. - **Misted Sealed Unit Replacement**: Where the frame is still sound, a failed double-glazed unit is swapped out without disturbing the surrounding frame. - **Made-to-Size Frame Supply & Fit**: Non-standard openings in older terraced or semi-detached homes are measured and fitted with made-to-size frames. - **Trickle Vent Fitting**: Included where Approved Document F requires it. - **Old Frame Removal & Disposal**: Taken away as part of the job, not left on site. - **Draught Seal & Making Good**: All faces sealed and finished after fitting. ## When repair is not enough, full replacement done properly stops the problem for good The material choice, uPVC, timber, or aluminium, matters less than getting the opening condition right before the new frame goes in. Many properties across Havering carry original or early-generation frames that are now warping, letting in draughts, or showing misted sealed units that cannot be fixed without removing the sash. The frame is assessed first: if the frame itself is sound, a sealed unit swap may be sufficient. Where the frame has rotted, shifted, or failed at the corners, full removal is the right call, and the quote explains why. Once the old frame is out, the opening is checked for damp, rot, and structural condition before the new unit is measured in. Older homes in the borough often need made-to-size frames rather than standard units. The replacement window, uPVC, timber, or aluminium, is fitted, shimmed level and square, and sealed on all faces. Trickle vents are included where required by Approved Document F. Replacement windows in a dwelling require FENSA registration or a Building Regulations completion certificate to meet Part L thermal performance requirements. The installer handles self-certification, so the paperwork is in order when the job is finished. The written quote lists frame supply, glazing unit, labour, old-frame removal, and certification as separate line items.

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. ### Is uPVC always the cheapest option? 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. ### Will the installer be able to match non-standard frame sizes in older homes? Yes. Many terraced and semi-detached properties in Havering have openings that do not match standard unit sizes. Each opening is measured on site, and made-to-size frames are ordered where needed.
