If you’re looking to enhance the character, efficiency, and value of your home, authentic sash windows are a timeless choice — but only when installed or restored by experienced sash window specialists.
At Quality Finish, we combine craftsmanship, precision, and traditional techniques with modern performance standards. Whether you need a full replacement, refurbishment, draught-proofing or maintenance, our team delivers exceptional results for every listed or period property.
Not all window installers are sash window experts. Sash windows are unique:
They rely on counterweights and cords rather than modern hinges.
They require precise balance and draught-proofing for smooth operation.
They must preserve heritage aesthetics in period homes.
Our sash window specialists understand every detail — from timber selection to weather performance — ensuring long-lasting, beautiful results.
We install high-quality timber sash windows tailored to your property’s style. Whether traditional or slimline double-glazed sashes, we offer solutions that boost energy efficiency and visual appeal.

Q: What makes sash windows different from casement windows?
A: Sash windows slide vertically (or sometimes horizontally) using weights and cords — unlike casement windows that swing open on hinges.
Q: Can sash windows be double glazed?
A: Yes — modern slimline units can be fitted to traditional designs to improve insulation without losing character.
Q: How long does sash window restoration take?
A: Timelines vary by scope, but most restoration projects are completed efficiently, with minimal disruption.
