Timber casement window restoration.
Suitable for timber windows.
For over 25 years we have breathed new life into countless well-loved historic buildings. We are experts in timber casement and sash window restoration and are proud to be trusted and recommended by the UK’s most respected heritage architects and developers.
Time eventually takes its toll on historic timber. Ageing affects us all! We have undertaken window and timber repairs on historic buildings across the UK and recognise heritage building principles such as The Society for the Protection of Ancient Buildings.
Our expert restoration work is vital in maintaining structural integrity, and we have unrivalled experience of working with historic timber for listed buildings and conservation areas.
Our ethos is to repair timber whenever possible. Sometimes we recommend a window survey to determine whether it’s better to repair or replace. Many TRC projects have a mix of repaired and replacement windows.
And while our core expertise is in heritage sash window restoration, we can also carry out timber repairs and replacement joinery work to fascia boards, soffits, external timber beams and structural joists and columns and heritage casement windows as well.
Our work combines unbeatable craftsmanship with the finest materials, latest technology and three decades of market-leading experience. Speak to us today to find out how we can help.
Where timber repairs are viable, we use a professional resin repair system called Repair Care. Being one of the most sustainable innovations this is a versatile system that provides fast and durable timber repairs. In the skilled hands of our window restorers, the repairs are seamless once finished and painted.
Draught-proofing isn’t just about keeping the cold out. Our expert casement window restoration specialists add insulation via hidden, rebated sealing strips in key places around the window, putting a stop to rattles too.
As a result, air leakage is reduced by up to 50%, and the casement sash opens and closes smoothly with minimum effort.
And with better insulation comes better thermal performance, as well as fewer occurrences of dirt, dust and rain ingress. That’s complete insulation from cold, leaks, and premature timber decay and damage, significant noise reduction also.
Our comprehensive draught-proofing ticks all the boxes (and fills all the gaps) - the benefits are:

Repair and restoration | Timber repair. Guidance for specification option: Decayed and damaged timber is gently prised out from windows, frames and sills, retaining as much of the original wood as possible. Where decay is severe, sections of timber is replaced with new joinery work to closely match the original. Whole cills or cill fronts can be replaced seamlessly to match the original window profile. The remaining timber is treated with a multi-stage epoxy resin repair system called Repair Care. Using specialist tools, the surface of the repair is carefully smoothed to match the shape of the original timber, so that it blends seamlessly. Finally, the window is stained or painted as required. |
Weatherpiles | Draught proofing. Guidance for specification option: Draftfix system which typically uses a weather pile with a central fin, fixed into a plastic carrier which is rebated into the casement. The weather pile prevents dust and dirt ingress, and the central fin contributes to air tightness. All the seals are rebated into the casement, which means no unsightly, protruding, face-fixed seals. Draught proofing is applied around the perimeter of the opening casement window, ensuring thorough, effective sealing while still allowing the window to open freely. Verified to BS 6375-1. |
