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.

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 Walmley: common questions

Which is better, bi-fold or sliding doors?

It depends on how you use the space. Bi-folds open almost the whole width, which suits summer living and wide openings onto a patio. Sliders have fewer, larger panes and slimmer frames, so they give a better view when closed and never take up room when open. Sliders are often the better pick where the doors stay shut for most of the year.

Do you cover Walmley?

Yes. Walmley (B76) is about 9 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.

Will I need permission from the council in Walmley?

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