A Glimpse of What We Do
Over the years, we’ve designed and installed secondary glazing for thousands of windows, in homes as well as historic, heritage and commercial properties.
No two buildings are the same, and original windows can present all kinds of challenges — from unusual shapes and curved systems to stained glass and large bay windows. We also carefully work around existing shutters, blinds and original ironmongery, with colour matching available to complement the existing windows and interiors.
We also help with draught-proofing for doors, carefully designed to improve comfort while retaining their character and traditional features.
Our approach is always to work with the building, not against it, creating bespoke solutions that respect the character and craftsmanship of the original windows and doors.
Here are just a few examples of the different installations we’ve completed over the years.
