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.
Anyone planning bifold or sliding doors in Chessington wants three things: a clear price, a realistic timetable and a tidy job. We publish a guide of £3,900–£10,500 including VAT for London up front, explain that work normally takes 1–2 days to fit into a ready opening, and confirm both in writing after a free survey of your property.

Homes in London
London's housing is dominated by Victorian and Edwardian terraces, often in yellow London stock brick, with Georgian terraces in central districts and mansion blocks across many inner areas. Outer boroughs have large belts of interwar semis, and there are extensive post-war council estates. Many houses have been split into flats, and conservation areas are widespread.
London Clay shrinks and swells with the seasons, and street trees close to houses can contribute to movement, which affects foundation design.
So when we survey a Chessington property for bifold or sliding doors, the first step is working out how it was built and what has been changed since.
Do you need permission in Chessington?
The notes below cover England, which is where Chessington sits. Rules change and every property is different, so we speak to the council before pricing your job.
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.
The four stages
We look at the job
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.
Quote in writing
Next you receive a written quote with a fixed price for the agreed specification. It lists what is included, what is not, and how payments are staged, so you can compare it properly.
Booking the work
Once you accept, we agree start dates, order materials and deal with any planning, building control or neighbour notices the job needs. You'll know who is coming and when before work begins.
On site to finish
The work is carried out to the agreed specification, with floors and furniture protected and the site kept tidy. At the end we clean up, walk through the finished job with you and hand over any certificates.
Why homeowners choose us
Bifold and sliding doors in Chessington: questions
Will large glass doors make my room cold?
Large glass doors lose more heat than an insulated wall, but modern double glazing with thermally broken frames performs far better than older patio doors. Solar control glass helps stop south-facing rooms overheating in summer. In extensions, building control looks at the total glazed area, so heat-loss calculations may be needed. We can suggest glass specifications that balance light, warmth and cost.
How long will bifold or sliding doors take?
On a typical home, allow 1–2 days to fit into a ready opening. Larger projects, older buildings and extra work found once things are opened up can extend that, while simpler jobs may be shorter. Your quote includes an estimate of time on site, and your point of contact keeps you updated on the programme as the work progresses.
Can I have a level threshold?
A level threshold means the door track sits flush with the floor, so there is no step between inside and out. Most aluminium bifolds and sliders can be fitted this way, but the outside paving must sit just below the track with a drainage channel to keep rain out. Rebated thresholds give stronger weather protection with only a small step. We check floor and patio levels before recommending either.
Which postcodes in Chessington do you cover?
We cover KT5, KT6, KT7 and KT9, along with the rest of London. If your postcode is not listed, get in touch anyway: our coverage is UK-wide, and we can usually arrange a survey wherever you live. Enter your postcode in the guide-price tool or contact form and we will confirm.
How long do bifold doors take to make and fit?
Aluminium bifold and sliding doors usually take several weeks to manufacture after the survey, depending on the supplier and colour. Fitting into a ready opening normally takes one to two days, including sealing and finishing trims. If we are widening the opening, allow a few extra days for the structural work and making good before the doors arrive. We give you the expected timeline with your quote.
