We are a London-based timber sash window specialist. We do one thing - timber sash windows and doors - and we do it properly.
Kensington Sash (Windows) Ltd does one thing: timber sash windows and doors in London. We repair them, restore them, and replace them. We also supply the doors and casements that go alongside them.
We are not a multi-trade contractor. We don't do rendering, roofing, or general building works. The focus is deliberate - it means everyone involved in your job knows timber sash windows properly, not as one item on a long service menu.
Every job starts with a personal site visit. We take precise measurements, assess each window honestly, and produce a written quote broken down window by window. There is no hard sell, and no upselling into services that don't make sense for the windows in front of us.
Installations are carried out by two-person teams - a fitter and a labourer working together. Dust sheeting and extraction are standard. Properties are left clean at the end of each day.
Our office is at 239 Kensington High Street, W8 6SN. We serve all London postcodes, with the deepest experience in the conservation areas of West and Central London.
Kensington Sash (Windows) Ltd is registered in England and Wales, Company Number 16036440. Business email: info@kensingtonsash.co.uk.
Every property is surveyed in person - no estimates from photos, no hard sell.
