UPVC sliding sash windows

It depends on the number and style, but as a general rule a whole house — typically eight to ten windows — is fitted in one to two days. We survey before the windows are made and manufacture every frame to the exact size of the existing opening, which keeps time on site down.

Very. All opening windows have locking handles as standard, and every window is internally beaded — the trims holding the glass in are on the inside, so the glass can't be removed from outside to get into the property. Many of our products are Secured by Design accredited, the official police initiative for designing out crime, and we can supply an endorsed upgrade with extra security on top.

Every window we supply is BFRC A-rated as standard — the highest rating a double glazed window can achieve. Ratings above that need triple glazing, which we can supply, though it costs considerably more than double.

Yes, toughened glazing comes as standard on all our glass units. A lot of firms fit standard double glazed units and charge extra for toughened.

We take them out and take them away. They go to recycling facilities where possible, and are disposed of properly where not.

Yes please — curtains, blinds and anything on the sills need moving before we arrive so the fitters have clear access to the windows.

Not normally. Repairing, fitting or replacing windows and doors doesn't usually need permission unless the building is listed. If you're in a conservation area or another designated area, check with your local planning authority first.

All our windows and doors come with a comprehensive 10-year insurance-backed guarantee, so the cover outlasts the invoice. Roofing and building work carries its own guarantee, and ProPERLA coatings come with a 10-year manufacturer's guarantee on top of ours.

Yes. Windows, doors, roofing, building work, electrics and coatings are all our own teams. That's the point of the business — one contract and one point of contact, rather than you co-ordinating five firms and absorbing the gaps between them.
