Devon: aluminium sliding doors
Lift-and-slide doors raise the panel off its seals when the handle is turned, so it glides easily, then lower it back onto the gaskets when closed. This allows very large, heavy panels with good weather sealing. Standard in-line sliders are lighter, simpler and usually cost less.
Making an opening wider for new sliding doors is structural work that needs building control approval and a correctly sized lintel or steel. Replacing doors in the existing opening is simpler. Flats, listed buildings and conservation areas may also need planning or other consent for the change.
Replacing patio doors in the same opening usually takes about a day on site, longer for wide multi-panel systems or where heavy glass needs extra hands or lifting gear. The doors are made to the survey sizes first, and the lead time is confirmed in writing with the quote.
Sliding door panes reach near the floor, so they need safety glass. In England, Approved Document K treats glass in doors, and in side panels within 300mm of a door's edge, up to 1500mm from the floor as critical. Toughened glass is standard; laminated adds security and holds together if broken.

What applies in Devon
Approved Document K requires safety glass in critical locations in England: glazing in doors and in side panels within 300 mm of a door, up to 1500 mm above floor level, and any glazing in walls or partitions up to 800 mm above floor level.
Approved Document L sets the minimum energy performance for replacement windows and doors in existing homes in England: a U-value of 1.4 W/m²K, or Window Energy Rating band B for windows; doors can instead meet a Door Set Energy Rating (band B, or band C for doors more than 60% glazed); rooflights need 2.2 W/m²K.
Devon has its own coastline, so for homes and businesses near the sea, salt air and wind-driven rain are part of the brief. Salt and sand collect in sliding door tracks near the coast, wearing rollers and seals more quickly, so tracks need more frequent cleaning. Stainless running gear, a coating suited to marine exposure and a raised threshold help on exposed elevations facing the sea.
Large sliding panels are heavy and long, so city installations need planned access through the house, parking nearby and sometimes lifting equipment for upper floors or balconies. Flats need freeholder consent and planning permission, and acoustic glass helps on busy roads.

Choosing your sliding doors
Slimline aluminium sliders
Very narrow frames and interlocks for the widest view, powder coated in a range of colours, suited to large openings.
Lift-and-slide doors
Panels lift off their seals to glide, then drop to seal tightly when closed; suited to very large, heavy glass panels.
uPVC patio doors
A lower-cost in-line sliding door with chunkier frames, available in white, grey and woodgrain foils for standard openings.
Multi-track configuration
Two, three or four tracks so several panels stack behind each other, opening one or both sides of the frame.
Sliding Doors in Devon: questions
How long does it take to install sliding doors?
Replacing a typical set of sliding patio doors takes about a day on site, and large multi-panel or lift-and-slide systems can take longer, especially if lifting equipment is needed. The doors are made to order first, and the manufacturing lead time is confirmed in writing when you accept the quote.
How much do sliding patio doors cost?
The cost of sliding patio doors depends on the width and height, the number of panels and tracks, aluminium or uPVC, standard or lift-and-slide hardware, colour, glass and threshold. Large slimline aluminium systems sit at the upper end. See the guide prices for typical ranges; the written quote fixes the price for your exact specification.
Can sliding doors have a level threshold?
Yes, many sliding door systems offer a low or flush bottom track for near level access. They need good external drainage and some shelter, because a flush track is less weather resistant than a raised sill. On exposed elevations, a slightly raised threshold is often the more reliable choice, and the survey checks which suits your patio.
Why is my sliding door so hard to open?
A sliding door usually becomes stiff because of grit in the track, worn or seized rollers, or a panel that has dropped out of adjustment. Cleaning the track often helps, and rollers can sometimes be adjusted or replaced. If the frame has distorted or the panels are very heavy, replacing the doors is often the more lasting fix.
