Bifold doors are glazed panels that fold and stack to one side to open up a wide gap, while sliding doors glide past each other on tracks; both connect a living space to the garden and bring in more daylight.
If you have bifold or sliding doors on your list for a property in Sevenoaks, we can help from the first measurements to the final clean-up. For a typical home, plan for 1–2 days to fit into a ready opening, though larger or more complex jobs take longer. We cover postcodes TN13 and nearby Tonbridge, Swanley and Tunbridge Wells, and every quote we send is fixed for the scope described in it.

Local housing and bifold or sliding doors
Kent's older buildings include oast houses, weatherboarded cottages, Wealden timber-framed houses and Kentish ragstone walls. Medway towns have long rows of Victorian terraces, Margate and Ramsgate have Regency and Victorian seafronts, and Ashford, Maidstone and Dartford have seen large new estates alongside interwar and post-war housing.
Victorian terraces suit loft rooms and rear extensions; weatherboarded and timber-framed buildings may need cladding repairs and lime work. Newer estate homes often take garage conversions, porches and landscaping.
Whatever era your Sevenoaks home dates from, we plan bifold or sliding doors around how it is actually built rather than a one-size-fits-all specification.
Do you need permission in Sevenoaks?
England, Wales, Scotland and Northern Ireland each handle planning a little differently. Sevenoaks comes under England, covered below, and we raise any questions with the council before your quote is finalised.
Replacing windows and doors on a house is usually permitted development in England when the new ones look broadly similar to the old. Flats, listed buildings and homes covered by an Article 4 direction can need consent, and conservation areas may limit materials or styles.
Replacement windows and external doors must meet Building Regulations for energy efficiency, ventilation and, on upper floors, escape. The work is either self-certified by an installer registered with a competent person scheme or signed off by building control.
Rules change and every property is different, so we check the planning history and constraints for your address before we quote.
From survey to handover
A visit to your home
A free survey comes first. It gives us what we need to price bifold or sliding doors properly, including dimensions, existing materials and access for deliveries, and gives you the chance to ask anything you like.
Price and scope agreed
We turn the survey notes into a written quote. The price is fixed for the specification we agree, and the document sets out materials, scope and payment stages in plain language.
Booking the work
Preparation matters as much as the build. We agree access, parking and working hours with you, order materials in good time, and confirm any permissions so the job isn't held up once it starts.
Build and hand over
The job proceeds in the order set out in the programme, with dust and debris kept under control. Finally we tidy away, inspect the work together and pass the finished project over to you with its paperwork.

Questions about bifold or sliding doors in Sevenoaks
What happens at the survey?
We visit your home at a time that suits you, look at the area involved, take measurements and check access, condition and any services that might be affected. We talk through what you want from bifold or sliding doors, explain the options and answer questions. There is no charge and no obligation; afterwards we send a written quote.
Can I stay at home during the work?
In most cases, yes. Most people can live at home throughout, and we plan the work to keep disruption down by protecting floors, agreeing working hours and keeping access routes clear. Bigger jobs affecting kitchens, bathrooms or heating may mean a short spell with reduced facilities, and we talk this through with you at the survey.
How do I maintain bifold doors?
Bifold doors need simple, regular care to keep them running smoothly. Vacuum or brush grit out of the bottom track every few weeks, wipe the frames with warm soapy water and avoid abrasive cleaners. Once or twice a year, lubricate the rollers, hinges and locks with a silicone spray. If the panels start to drop or catch, the hinges can usually be adjusted rather than replaced.
Are bifold doors secure?
Modern bifold and sliding doors are designed to be secure, with multi-point locks, shoot bolts into the frame, internally beaded glass and toughened or laminated glazing. The traffic door, which you use day to day, has a cylinder lock that can take an anti-snap barrel. Sliding doors also have anti-lift features. We explain the locking on each option so you can compare like for like.
How much do bifold doors cost?
Bifold doors cost £3,400–£9,000 for a typical 3m opening, supplied and fitted. As a rough guide, allow around £900–£2,000 per metre of width plus the fixed costs of fitting, depending on frame material and glass. uPVC sits at the lower end and slimline aluminium at the top. Widening the opening with a new steel adds to the price. We confirm a fixed figure after measuring.
