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.
Homeowners in Pimlico usually consider bifold or sliding doors for one of a few reasons: something has worn out, the house no longer suits the way they live, or they are getting it ready to sell. We visit, agree a specification and put a fixed price in writing. Most jobs like this take 1–2 days to fit into a ready opening, and we work across London, including Westminster, Battersea and Chelsea.

What are homes like around Pimlico?
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.
Terraces suit side-return extensions and rear dormer loft conversions; interwar semis commonly take hip-to-gable lofts. Shared party walls, restricted parking and conservation rules often shape the plans and the programme.
These patterns matter for bifold or sliding doors: older walls, roofs and floors in Pimlico can need different materials or extra preparation compared with newer homes.
Do you need permission in Pimlico?
Because Pimlico falls under England's rules, the guidance below is the version relevant to you. Before sending a price, we check your property's position with the council.
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
Survey and measure
We begin by looking at the job in person. During the free survey we discuss options, materials and budget for bifold or sliding doors, and photograph or measure anything the quote needs to reflect.
Price and scope agreed
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.
Dates and permissions
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.
The work itself
Work goes ahead as scheduled and you deal with one contact throughout. When the last trade leaves, we clear and clean the site, talk you through what has been done and pass on any certificates and care instructions.
Why homeowners choose us
Frequently asked questions
Can you fit bifold doors where I have a window now?
Bifold doors can usually replace a window by cutting the wall down to floor level and, if the opening is being widened, fitting a new lintel or steel beam. A structural engineer sizes the beam, and building control approval is needed. Radiators, pipes and cables under the window may need moving. We check all of this at the survey and include it in a single written quote.
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.
Which postcodes in Pimlico do you cover?
We cover SW1, SW1E, SW1H and SW1P, 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.
Can you combine bifold or sliding doors with other work?
Yes. Because we manage several trades under one contract, we can plan bifold or sliding doors alongside other work on your Pimlico home, such as new windows with rendering, or a kitchen refit with an extension. Combining jobs can reduce repeat set-up such as scaffolding, skips and access, and every element is listed and priced in the same written quote.
