Repairing Timber Windows
Why Repair Instead of Replace?
Many homeowners are wrongly pressured into believing their old windows are "worn out". In reality, the slow-grown heartwood used in historic windows is vastly superior to modern timber, meaning they can almost always be saved through precise spliced repairs and advanced resin consolidation.
We follow Historic England and SPAB guidelines wherever possible.
-
Bypass Planning Nightmares
Replacing historic windows usually requires consent. Repair is classed as maintenance, sidestepping the red tape entirely.
-
Keep Authentic Aesthetics
Avoid the chunky, fake look of PVC-u plastic frames.
-
Modern Thermal Comfort
Our draught-proofing upgrades can reduce air infiltration by over 80%.
A repair you can repair again
A traditional window is an assembly of parts that were always meant to come apart — that is what the staff bead and the parting bead are for. If a pane breaks, you replace a pane. If a bottom rail rots, we splice in new timber and the rest of the window carries on. The smallest repair you can make is small, and it can be made again, by anyone with the skill, out of materials nobody controls.
A sealed unit is one part. When the seal fails you replace the unit, often the sash with it, and if the profile has been discontinued you replace the window. If several match, you replace the elevation.
Victorian Vicarage
We repaired all original windows at this Victorian Vicarage with splices made from the same type of wood and created using modern resin consolidation methods to repair rotten cills. By using a discreet method of draught-proofing the frame and using only the original historic glass, we greatly increased the thermal comfort of the property while maintaining its genuine 19th century feel.
Georgian Terrace
The Georgian terrace received cost-effective timber splicing and draught-proofing upgrades. These upgrades improved thermal comfort but retained the authentic slim glazing bars, which did not require listed building consent to do so. The cost of replacing the windows was significantly higher than these upgrades.
School House
The old village school house had large wooden windows that had experienced serious water damage from rot. We used new solutions like resin consolidation and precise timber splicing on the original frames instead of replacing them with new frames. These methods of restoration were much more economical (70% less expensive than replacing with new windows) than new custom made windows and allowed us to conserve much of the village school house's original character and appearance through economical methods.
