East Grinstead: replacement bifold 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 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.
Thresholds range from a raised weathered sill to a low or flush threshold for level access between floor and patio. Low thresholds rely on drainage outside, such as a slot drain, and some shelter from driving rain. The right choice depends on exposure, patio levels and how the doors are used.

About East Grinstead for this job
- Postcodes covered
- RH19 and the surrounding area, including Horley, Crawley and Crowborough
- Coast
- East Grinstead is well inland, around 34 km from the nearest coast, so salt exposure is not usually a factor.
- Daylight and sun
- In East Grinstead the midwinter sun reaches about 15° above the horizon at noon, with roughly 7.7 hours of daylight, rising to about 62° and 16.3 hours in midsummer. A wide bifold opening on a south or west-facing wall brings in strong sun and can overheat a room, so solar-control glass or integral blinds may help. North-facing bifolds benefit from high light-transmission low-E glass to make the most of winter daylight.
- Access and setting
- Rural gardens often slope or sit lower than the floor, so threshold height and drainage need careful planning. Exposed open sites benefit from stiffer aluminium systems, raised thresholds and outward-opening doors that seal against the wind.
- Rules in England
- 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.

Bifold Doors in East Grinstead: questions
Do bifold doors need building regulations approval?
Yes. Fully glazed replacement doors like these are controlled fittings, and in England an installer registered with a competent person scheme can self-certify them, or building control approves the work. A new or widened opening is structural work and needs building control approval for the lintel or steel. Wales, Scotland and Northern Ireland set their own requirements.
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.
Should bifold doors open inwards or outwards?
Outward-opening bifold doors are more common because the stacked panels sit outside and leave the room clear. Inward opening suits balconies, raised decks or tight patios where outward panels would block the space. The direction also affects weather performance and furniture layout, so it is decided at survey with the room plan in mind.
Can I fit bifold doors in a conservation area or a flat?
Possibly, but you may need permission first. Flats and maisonettes do not have the same permitted development rights as houses, and listed buildings need consent for significant works. Conservation areas and Article 4 directions can restrict changes visible from the street. Check with your council before ordering; the council can tell you what an application needs, and we can provide product details and specifications to support it.
