Choices to weigh up in Dorridge

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.

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.

Bi-fold and patio doors in Dorridge: common questions

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.

Which postcodes in Dorridge do you work in?

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

How long does fitting take?

Fitting doors into a ready opening usually takes one to two days. If we're widening the opening, allow another two to four days for propping, cutting, fitting the beam, inspection and making good. Manufacture usually takes four to eight weeks after the design is signed off, depending on the material and colour.

Who approves bi-fold and patio doors in Dorridge?

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