Choices to weigh up in Knowle

Vertical sliding sash windows

uPVC sliding sashes reproduce the look of Victorian and Edwardian box sashes without the rattles, draughts and repainting. They use spiral balances instead of weights, tilt inwards for cleaning and can include decorative horns and astragal bars. They cost noticeably more than casements but keep the character of a period front.

Bay and bow windows

Bays are three or more windows set at angles; bows are a gentle curve of four or five. Replacement bays are built with structural bay poles or posts so the window doesn't carry the load of the brickwork or roof above. We check whether the existing bay is load-bearing before quoting, because that changes how it's supported during the swap.

uPVC windows in Knowle: common questions

What guarantee comes with new windows?

Frames, glass and hardware are covered by the manufacturer's guarantee, and the terms for your specific windows are set out in your quote. Ask what's covered for sealed units misting up, hinges and locks, as these differ between suppliers. Keep the guarantee paperwork with your building regulations certificate, because both are useful when you come to sell.

Which postcodes in Knowle do you work in?

We cover B93 and the streets around them. If you're on the edge of Knowle, neighbouring Dorridge and Balsall Common are covered too.

How much do new uPVC windows cost for a three-bed semi?

Most three-bed semis have eight to ten windows, and replacing them all in white uPVC typically costs around £3,800–£6,500 in total in the West Midlands, including fitting and removal of the old frames. A bay window, colour finishes or tilt-and-turn sashes push it higher. We price each window separately in your quote, so you can see exactly where the money goes and phase the work if you'd prefer.

Does Solihull Council need to approve my new windows?

You won't usually need planning permission, but the work must meet Building Regulations. Building control in Knowle is provided by Solihull Council or a registered building control approver, and some work is self-certified by registered installers.
