Havering has a high proportion of older terraced and semi-detached housing where original timber windows are still in place. Rot at the sill or corners, recurring draughts despite repainting, and sashes that no longer close flush are the clearest signs that repair has run its course. The installer assesses the frame condition on site and sets out both options, repair and replacement, in the written quote before anything is removed.
Once replacement is agreed, the old timber frame and sashes are taken out carefully to avoid damaging the surrounding plasterwork or external render. The opening is inspected for damp, rot spread into the surrounding structure, and any movement in the lintel or sill. Any damage found is noted in the quote before the new frame is ordered, so there are no surprises on the day of fitting.
The new timber window is fitted into the prepared opening, sealed on all faces with sealant, and checked for smooth operation before the installer leaves. Glazing units are double-glazed as standard, and draught-proof seals run the full perimeter of the sash. Single windows can be replaced independently, there is no requirement to change all windows at once if only one has failed.
