Bi-fold and patio doors in Darlaston

Planning your bi-fold or patio doors in Darlaston

This kind of work rarely needs planning permission, but it does have to comply with Building Regulations, and some parts must be certified by a registered installer or signed off by building control. In Darlaston, building control is provided by Walsall Council or a registered building control approver (formerly an approved inspector).

If a new beam bears on a wall you share with a neighbour, the Party Wall etc. Act 1996 may apply.
With a traffic door on a bi-fold set, you don't have to open every panel to step outside.
Widening an opening needs a structural engineer's design and building control approval.

Which options suit homes in Darlaston?

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.

Before you book in Darlaston

What guarantee comes with the doors?

The frames, glass, rollers and locks are covered by the manufacturer's guarantee, and the terms for your doors are set out in your quote. Ask how sealed units, running gear and powder coating are covered, as these vary between systems. Keep the guarantee with your certificate and any structural sign-off from building control.

Do you cover Darlaston?

Yes. Darlaston (WS10) is about 4 miles from our West Bromwich base and inside the area we cover. Call 0800 088 6248 or send the form on this page to book a free survey.

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 Darlaston?

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