Aluminium Bi-fold & Sliding Doors in York

At SM Windows & Doors, we supply and install aluminium bi-fold and sliding doors in York and right across North Yorkshire, helping homeowners open up their living spaces and let the garden in. Whether you are extending a kitchen in Haxby, updating a family home in Acomb or finishing a new build near Poppleton, these doors turn a wall into a wide, light-filled opening.

Aluminium is the natural material for big glazed doors. It is strong enough to hold large panes on slim frames, so you get more glass, more daylight and a clean modern line. On a bright day you can fold or slide the doors right back and bring the outside in, then close them up snug against the Yorkshire weather when the evenings draw in.

Bi-fold or sliding: which suits your space?

Both styles have their strengths, and the right one depends on your room and how you want to use it. Bi-folds concertina neatly to one side and fully open the wall, which is lovely for entertaining. Sliding doors keep bigger uninterrupted panes of glass and take up no floor space when open, so they suit tighter rooms. We are happy to talk both through with you. Here is what we offer:

  • Aluminium bi-folding doors that fold back to open up your space completely
  • Aluminium sliding doors for wide openings with minimal frame and maximum glass
  • Slimline profiles for a clean, modern look
  • A wide range of colours and finishes, including anthracite grey, black and bespoke RAL options
  • High-performance glazing that helps keep rooms warm and quiet
  • Smooth-running, secure systems built for daily use

Fitted properly, finished neatly

Every door is made to measure and installed by our own team, so the tracks run true and the seals do their job for years. We serve York and the villages around it, including Clifton, Fulford, Bishopthorpe, Strensall, Tadcaster, Wetherby, Selby and Easingwold, and we are glad to come out and measure up in person.

These doors work brilliantly alongside matching aluminium windows in York, and they are a popular finishing touch for a conservatory or orangery. If you are after even more light, a roof lantern or flat roof light above the opening makes a real difference.

Frequently asked questions

How much do aluminium bi-fold and sliding doors cost?

As a rough UK guide, aluminium bi-fold and sliding doors typically run from a couple of thousand pounds for a smaller opening up to several thousand for wider, multi-panel sets. The final price depends on the number of panels, the size of the opening, your glazing and the finish you choose, so figures move around a fair bit. The best way to know where you stand is to have us pop out, measure the opening and give you a proper quote.

Which is better, bi-fold or sliding doors?

It really comes down to your room and how you want to use it. Bi-folds concertina neatly to one side and open the wall up completely, which is lovely for entertaining and summer barbecues. Sliding doors keep bigger uninterrupted panes of glass and take up no floor space when open, so they suit tighter rooms and anyone who wants the widest possible view of the garden.

How slim are the frames and sightlines?

Because aluminium is so strong, the frames can be kept slim while still holding large, heavy panes of glass. That gives you narrow sightlines and more daylight, with less frame breaking up the view. On a sliding door in particular, the slim central meeting point means the garden feels like part of the room even when the doors are shut.

Do aluminium doors need much maintenance?

Not really, which is one of their best features. The powder-coated frames just need an occasional wipe down, and it is worth keeping the tracks clear of grit so the doors keep gliding smoothly. Because we fit every door ourselves across York and North Yorkshire, we make sure the rollers and seals are set up properly from day one, so they run true for years.
