Bifold doors for homes and businesses in Wimbledon
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.
The price of bifold doors depends on overall width and height, the number of panels, material and profile system, colour, glass specification, threshold type and the condition of the opening. Wide or very tall sets and triple glazing add cost. See the guide prices for typical ranges; the written quote fixes your figure.
Bifold doors run on rollers along a track, either top-hung with the weight carried by the head or bottom-rolling with the weight on the threshold. Top-hung systems depend on a strong, stiff lintel or steel above, so the glazier checks support before ordering, because sagging heads cause doors to bind.
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.

About Wimbledon for this job
- Postcodes covered
- SW19, SW20, SW17 and the surrounding area, including Morden, Mitcham and Wandsworth
- Coast
- Wimbledon is well inland, around 40 km from the nearest coast, so salt exposure is not usually a factor.
- Daylight and sun
- In Wimbledon 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.

In England, replacing a whole window, roof window or glazed external door is building work. It has to be notified to building control, either by an installer registered with a competent person scheme such as FENSA or Certass, or through a building notice to the council. Replacing only the glass in an existing frame is a repair and is not notifiable.
Choosing your bifold doors
Low or flush threshold
A low-profile track for near level access between inside and out, paired with drainage outside and some shelter.
uPVC bifolds
A lower-cost option with bulkier frames, suited to smaller openings with fewer panels, available in white, grey and woodgrain foils.
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 Wimbledon: questions
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.
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.
How long does it take to fit bifold doors?
Fitting a typical set of bifold doors takes one to two days on site, depending on width, removal of old doors and making good around the opening. The doors are manufactured to the survey sizes first, and the lead time depends on the system and colour; it is confirmed in writing when you accept the quote.
