Aluminium bifold doors in Mitcham: what to know
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.
Security on bifold doors comes from multi-point locks on the traffic door, shoot bolts top and bottom on the folding panels, internally glazed beads, anti-lift track design and hinges that cannot be removed from outside. Ask whether the system has been tested to PAS 24 and fit an anti-snap cylinder.
The number of panels sets how the doors open. Odd numbers, such as three or five panels, usually include a traffic door that opens on its own for everyday use. Even numbers can split to both sides. Panels can fold inwards or outwards, and outward folding keeps the room clear.
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 a typical job includes
- Fitting, levelling, adjusting and sealing the frame
- Removal and disposal of any existing doors
- Written guarantee terms and advice on building regulations sign-off
- Survey of the opening, support above and floor levels

Working in Mitcham
- Postcodes covered
- CR4, SM4, SW17 and the surrounding area, including Morden, Wimbledon and Streatham
- Coast
- Mitcham is well inland, around 38 km from the nearest coast, so salt exposure is not usually a factor.
- Daylight and sun
- In Mitcham the midwinter sun reaches about 15° above the horizon at noon, with roughly 7.6 hours of daylight, rising to about 62° and 16.4 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
- 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.
- 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 Mitcham: questions
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.
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.
What guarantee comes with bifold doors?
Manufacturer guarantees apply to the frames, coating, hardware, rollers and sealed units, and the terms are confirmed in writing. Cover for running gear can depend on regular cleaning and adjustment, so read the conditions. Guarantee terms for the installation are set out in writing with your quote, so you know what is covered before going ahead.
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.
