Double Glazing Upgrading
We offer a unique service where a lot of people would love to upgrade their windows to double glazing but cannot for conservation reasons, We have a system where you keep your original frames and we insert new sashes in them keeping the section sizes the same with double glazing installed. It’s a way to keep your original aesthetics and benefit from double glazing and draught proofing. We call this a “retro fit”. we usually recommend a reasonably priced hardwood sash to replace the common softwood sash as with experience we find softwood sashes deteriorate rapidly compared to hardwood.
Draught proofing sash windows
Draught proofing your sash windows is a great way to stop the common “whistling window” when its rattling in the wind and letting cold air into your property. We don’t use the reasoning that your initial investment would be returned in saving on your heating bills as the numbers just simply don’t add up! However, if you want a warm cosy home with reduced bills then this is a great option to think about. We can guarantee draft proofing sash and casement windows and doors up to 95% from its original state so it really is worth while.
