Bi-fold doors in Leeds.

How bi-folds actually work

The panels hinge to each other and concertina to one side – fold left, fold right, or split from the middle. Most sets include one panel that opens like a normal door, so you're not folding the whole wall back just to let the dog out.

Bi-folds live or die on the fit

The track has to be dead level across the whole span for the panels to glide and lock cleanly. A set hung even slightly out of true will drag, stick, or refuse to sit flush. Our own team fits every one – and it's covered by our 10-year guarantee.

Frames, colours, glass

We'll talk through frame options, colours and glazing on the visit – including whether your wall can take the span or needs structural work first. Honest advice on what suits the opening, not what's easiest to sell.

Two, three or four panels: what fits your opening?

Most of the bi-fold doors we fit across Leeds have two, three or four panels – the wider the opening, the more panels it takes to keep each leaf a sensible size and weight.

You choose how they stack, too: fold left, fold right, or split from the middle so the panels park at both ends. And the traffic door – that everyday panel that swings like a normal door – matters more than most people expect. It's the one you'll use ten times for every time you fold the whole set back, so we'll help you put it where the footpath actually is.

Bi-folds, sliding patio doors or French doors?

There's no wrong answer – just the right one for your opening and how you'll actually live with it. We'll tell you straight which that is, even when it's the cheaper option. Still weighing it up? See all our doors in Leeds.

Locking and security

Do bi-fold doors need Building Regulations approval?

Yes – replacement glazed doors are a controlled fitting under Building Regulations, but when Wortley Windows & Doors fits your bi-folds there's nothing for you to arrange. We're CERTASS certified (registration 19‑1239), so the installation is self-certified and registered automatically – no council application, no chasing certificates. The one case that needs more is widening the opening itself: if a wall is coming out or a new lintel is going in, that structural work needs its own approval, and we'll tell you before anything starts.

Is a bi-fold actually right for your opening?

A bi-fold earns its keep when you'll genuinely fold the whole lot back. If the doors will spend most of the year shut with one panel in use, a slider or a pair of French doors gives you more glass and less frame across the same opening. Our bi-folds are uPVC. We fit no aluminium, and we'd rather say that here than have you find it out on survey day. On a uPVC set the sensible answer to a wide opening is more panels, not fewer big ones, so each leaf stays a weight the hinges and the track can carry.

Where an opening is wider than a sensible uPVC set covers, we say so rather than stretch one to fit. Sometimes the answer is a bi-fold with a fixed pane beside it. Sometimes it's a slider. What we won't do is give you a maximum width over the phone, because the honest figure depends on your opening, the wall above it and the weight of the glass. James and the team will stand at the opening, measure up, and tell you straight which of those three you're looking at.

Low threshold or weathered: what decides it

How exposed that wall is, and where the water can go. A low threshold takes the step out of the doorway, so there's nothing to catch a pram, a wheelchair or unsteady feet, and the kitchen floor runs straight out onto the patio. The trade-off is real, and worth hearing before you choose: the lower the upstand, the less sits between driving rain and your floor. A low threshold wants ground that falls away from the house, drainage that works, and ideally something overhead.

A weathered threshold gives up that level access and buys back protection, which is the right call on a rear wall that takes the wind and rain head-on. Neither is better in the abstract. What we look at on the visit is which way the wall faces, how sheltered it is, the floor level inside against the ground level outside, and who uses that door every day. Say if step-free access matters when you book your free quote, and we'll tell you what your house can actually carry.

The same opening, three different doors

Put a bi-fold, a slider and a pair of French doors on the same rear wall and you get three different rooms out of one opening. The bi-fold clears the whole aperture. The slider keeps the biggest, cleanest panes of glass but only ever opens half of it. The French pair asks least of the opening and still throws the back of the house open on a good day. Here's how they differ on the things people actually notice.

Which one wins is decided by your opening, not by a brochure. Read up on sliding patio doors and French doors while you're weighing it up, then ask for a free quote and we'll measure the opening before anybody talks you into anything. We're in Lower Wortley, so it's a short run out to most of the streets we cover.
