Options to consider in Marston Green

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.

French doors

A pair of hinged doors that open outwards or inwards, sometimes with fixed side panels. French doors suit narrower openings and older houses. They're the simplest and most affordable way to replace an old single back door, or to turn a window into a wider opening onto a patio.

Questions about bi-fold and patio doors in Marston Green

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 Marston Green do you work in?

We cover B37 and the streets around them. If you're on the edge of Marston Green, neighbouring Chelmsley Wood and Sheldon are covered too.

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.

Who approves bi-fold and patio doors in Marston Green?

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