Rather than completely replacing your timber windows, if the frames are in good enough condition to be saved, we offer full perimeter draught-proofing and can fit new double glazed sashes to the existing frames.

This is the most cost-effective option to improve thermal performance as well as preserve the original look and character of your property, with minimum disruption to your property and maximum impact. 

Draught-proofing and new double glazed sashes can reduce heat loss through the glass by at least 77% when compared to single glazing. 

As specialists in bespoke timber windows for period, listed and conservation properties, we can also carefully match your existing sashes down to the finest detail.
