Devon: folding patio doors
Bifold door tracks need keeping clean: vacuum or brush grit from the bottom track and drainage slots regularly, wipe frames with mild soapy water and lightly lubricate the locking points. Panels that drag or catch usually need adjustment at the hinges or rollers, which a glazier can carry out.
Bifold door panels have wider frames where they meet than a sliding door, because each panel needs its own frame and hinges. A five-panel set shows four vertical sightlines when closed. If the view matters more than a fully open wall, a sliding door may suit better, so compare both.
Bifold doors take longer to manufacture than standard doors because each set is made to the opening and coated to order. Fitting a typical set usually takes one to two days, depending on width, removal of old doors and any making good to plaster, flooring and the patio outside.
Creating a new bifold opening in an external wall is structural work that needs building regulations approval and a correctly sized lintel or steel beam. Replacing existing doors in the same opening is simpler. Planning permission may also be needed for new openings in listed buildings, flats or conservation areas.

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.
Replacing windows and doors with similar ones is usually permitted development for houses in England. Flats, listed buildings and homes in conservation areas or covered by an Article 4 direction can need permission, so check with the council first.
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 deposits gather in bifold tracks and on rollers, so coastal sets need more frequent cleaning, stainless or protected running gear, and a coating suited to marine exposure. Wind-driven rain makes a raised threshold or good drainage especially important on exposed elevations.
Long, heavy bifold panels need planned access through the house or a side passage, and parking close by for unloading. In terraces and flats, check permitted development rights, freeholder consent and conservation area rules before ordering.

Choosing your bifold doors
Glass specification
Toughened low-E double glazing as standard, with triple glazing, laminated security glass or solar-control coatings available.
Low or flush threshold
A low-profile track for near level access between inside and out, paired with drainage outside and some shelter.
Aluminium bifolds
Slim, stiff thermally broken panels that carry large glass units, powder coated in a wide range of colours and finishes.
Integrated blinds
Blinds sealed between the panes of each unit, controlled by a magnetic slider, so they never need dusting or catch on folding.
Bifold Doors in Devon: questions
Do bifold doors leak or let in draughts?
Well-made bifold doors fitted level and square should keep out wind and rain, but they rely on accurate installation, a sound lintel and working drainage. Leaks usually come from blocked track drainage, a flush threshold on an exposed elevation or panels that have dropped out of adjustment. Keeping the tracks clean prevents most problems.
Bifold or sliding doors: which should I choose?
Bifold doors suit you if you want almost the whole opening clear in summer, because the panels fold and stack to the side. Sliding doors suit you if you want the fewest frames and the widest view when closed, because large panels glide past each other. Many people decide by how often they will fully open the doors.
Are bifold doors secure?
Good bifold doors are secure when the traffic door has a multi-point lock and anti-snap cylinder, the other panels have shoot bolts top and bottom, the glass is internally beaded and the hinges and track resist lifting. Ask whether the system has been tested to PAS 24, and consider laminated glass for ground-floor doors.
Can bifold doors have a level threshold?
Yes, most bifold systems offer a low or flush threshold for near level access between inside and out. It works well with a drainage channel outside and some shelter from wind-driven rain, because a flush track is less weather resistant than a raised sill. The glazier checks the patio and floor levels and exposure at survey.
