As well as offering full replacement sash windows and timber casement windows, we can also fit new single or double glazed sashes/casements to the existing window frames, if the frames are in good enough condition to be saved.

As specialists in bespoke timber windows for period, listed and conservation properties, we can carefully match your existing sashes/casements down to the finest detail, with slimline double glazing from just 11mm thick. 

Draught-proofing and new double glazed sash windows can reduce heat loss by at least 77% when compared to single glazing. We offer a range of specialist options when it comes to double glazing for sash windows, including acoustic glass, laminated security glass and restoration glass for the authentic heritage look.
