Kempston: aluminium bifold doors
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.
Bifold doors are glazed down to floor level, so every pane needs safety glass. In England, Approved Document K treats glazing in doors within 1500mm of the floor as a critical location. Units are usually toughened, with laminated glass added where extra security or protection against falls is wanted.
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 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.

- Coast
- Kempston is well inland, around 93 km from the nearest coast, so salt exposure is not usually a factor.
- Daylight and sun
- In Kempston the midwinter sun reaches about 14° above the horizon at noon, with roughly 7.5 hours of daylight, rising to about 61° and 16.5 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.

Listed buildings in England need listed building consent for most changes to historic windows or glass, and conservation areas can restrict changes visible from the street. Speak to the council's conservation officer before ordering.

Bifold Doors in Kempston: questions
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.
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.
How much do bifold doors cost?
The cost of bifold doors depends on the opening width and height, number of panels, material, colour, glass, threshold type and the condition of the opening. Aluminium usually costs more than uPVC, and wider sets, triple glazing and special finishes add more. See the guide prices for typical ranges; the written quote fixes the price for your specification.
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.
