About Sash Timber Windows

Sash Timber Windows was founded on a simple principle: period properties deserve windows and doors that respect their heritage while delivering 21st-century performance. Too often, we saw beautiful Victorian and Edwardian homes compromised by unsympathetic plastic replacements or poorly fitted timber units.

We set out to change that. By combining traditional joinery techniques with modern innovations like slimline double glazing and advanced draught-proofing, we create products that are virtually indistinguishable from the originals but perform lightyears ahead.

Today, our South-West London workshop buzzes with a team of dedicated craftsmen who treat every architrave, glazing bar, and horn with the respect it deserves.
