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.

Our work combines unbeatable craftsmanship with the finest materials, latest technology and three decades of market-leading experience. Speak to use today to find out how we can help.
