Bi-fold and patio doors in Cradley Heath

Planning your bi-fold or patio doors in Cradley Heath

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 Cradley Heath, building control is provided by Sandwell Council or a registered building control approver (formerly an approved inspector).

A flush threshold needs the outside ground set lower, with drainage in front of the door.
Widening an opening needs a structural engineer's design and building control approval.
If a new beam bears on a wall you share with a neighbour, the Party Wall etc. Act 1996 may apply.

Options to consider in Cradley Heath

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.

Before you book in Cradley Heath

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.
