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 Crawley wants three things: a clear price, a realistic timetable and a tidy job. We publish a guide of £3,400–£9,000 including VAT for the South East 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.

Scope of the work

What are homes like around Crawley?
Chichester has Georgian brick streets, Downland villages use flint and brick, and Horsham stone slabs cover some older roofs. Worthing and Bognor Regis have interwar and post-war bungalows and semis, Crawley was planned as a post-war new town, and Wealden villages to the north feature tile-hanging and timber framing.
Bungalows commonly suit loft conversions and extensions; new-town homes often take window, roofline and cladding renewal. Flint and stone properties need lime repointing, and coastal homes may need external decorating more often.
If your house in Crawley fits one of these patterns, it helps us anticipate what bifold or sliding doors will involve, though we always confirm the details on site.
Planning and building rules in Crawley
England, Wales, Scotland and Northern Ireland each handle planning a little differently. Crawley 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
We look at the job
First, someone visits your home in Crawley to see the space, take measurements and note anything that could affect the work, such as access or the condition of what is there. There is no charge for this visit.
Written quote
The quote arrives in writing, not over the phone. It covers the full scope, the finishes you've chosen, any exclusions and the payment schedule, with a fixed price tied to that specification.
Getting ready
With the quote agreed, we book the work in and handle preparation: permissions where needed, building control notifications, material orders and access arrangements for your Crawley property.
Build and hand over
Our trades complete bifold or sliding doors while your point of contact keeps you updated. When everything is finished, we clear the site, take away waste and go through the result with you before handover.
What you can expect from us
Frequently asked questions
How much will bifold or sliding doors cost in Crawley?
As a guide, expect to pay £3,400–£9,000 including VAT for bifold or sliding doors in Crawley. That range is adjusted for the South East, which runs about 12% above the national guide. Where your project lands depends on size, materials, access and the condition of what is already there. We confirm a fixed price in writing after a free survey of your home.
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.
Should I choose bifold or sliding doors?
Bifold doors suit you if you want to open the whole width to the garden, because the panels fold and stack to one side. Sliding doors suit you if you mainly want the view, because they have fewer, larger panes and slimmer frames, though only part of the width opens. Sliding doors also take up no room when open. We help you weigh up how you will use the space in summer and winter.
Do you cover Horley, Horsham and East Grinstead?
Yes. As well as Crawley, we cover Horley, Horsham and East Grinstead and the rest of West Sussex. Our coverage is UK-wide, so the process is the same wherever you are: a free site survey, a quote in writing that fixes the price for the agreed scope, and one point of contact while the work is planned and carried out.
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.
