Which option fits your home?

Widening an opening

Turning a window into doors, or making an opening wider, means cutting the wall and fitting a new lintel or steel beam sized by a structural engineer. Building control must approve the structural work. We organise the calculations, temporary supports, steel and making good, and show these costs on their own lines in your quote.

Aluminium bi-fold doors

Slim, strong aluminium frames carry large glass panels and are made with a thermal break to meet energy rules. Three to six panels are typical, with a traffic door for everyday use so you don't open the whole set. They come powder-coated in almost any colour and suit kitchens and new extensions.

Bi-fold and patio doors in Sandwell: common questions

What should I check before ordering?

Think about the floor level inside and out: a flush threshold needs the patio set lower, with drainage at the door. Decide which side the panels should stack and where the everyday traffic door goes, keeping furniture in mind. If the doors face south or west, ask about solar control glass to keep the room cooler.

Do you cover the whole of Sandwell?

Yes — we cover Sandwell from our West Bromwich base, including Dudley, Walsall and Wolverhampton. Call 0800 088 6248 or send the form on this page to book a free survey.

How much do bi-fold doors cost?

A three-panel aluminium bi-fold for an opening of around 2.4 m typically costs £3,000–£5,000 fitted in the West Midlands, and wider four- or five-panel sets run to around £8,500. uPVC versions cost less. If the opening needs widening, add the cost of a steel beam, calculations and building control, which we price separately in your quote.

Does Sandwell Council need to approve my bi-fold or patio doors?

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