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.

Draft Proofing Sash Windows London

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.

We’re a passionate business with exceptional attention to detail

The journey started back in 1999 for Mark. as a 16 year old apprentice in Pocklington, North Yorkshire, where he learnt his craft as a bench joiner creating all types work from conservatories to staircases.
From there he went from strength to strength starting his own business in a workshop in York in 2004 where he made all things wood! his favorite thing to make was windows hence the new venture….
In July 2019 Mark made a big decision in his life and made the move to the big smoke, he’s new to the area but with 21 years experience under his belt producing nothing but high quality work he’s definitely got a lot to offer!!

Mark manufactured and installed the windows in my farm house. They had to be changed like for like as we live in a conservation area, when the windows arrived at our house I was amazed how every little profile matched the ones we were taking out. Definitely would recommend.
