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.
Every house in Putney is a little different, so we never price bifold or sliding doors from a brochure. We look at the structure, access and existing finishes first, then put in writing a fixed figure for the scope we settle on. As a rough steer, homeowners in London should budget £3,900–£10,500 including VAT, with work typically taking 1–2 days to fit into a ready opening.

What are homes like around Putney?
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.
Knowing the typical building types in London helps, but a survey of your own home in Putney is what decides the right approach to bifold or sliding doors.
Permissions for bifold or sliding doors in Putney
As Putney is in England, read the following with that system of planning and building control in mind. We check what applies to your house with the council before you receive a quote.
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.
How does the job run?
Survey and measure
Book a visit and we'll come to you. The survey covers measurements, the state of what's there now and any obvious constraints, so the price that follows is based on your actual home, not an average.
Quote in writing
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.
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.
Finish and handover
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.

Questions about bifold or sliding doors in Putney
Do I need planning permission in Putney?
It depends on the work, the size of the project, your property type and whether the building is listed or in a conservation area. Putney is in England, so England's rules apply. Many smaller jobs need no planning application, but some still need building control approval. We check what applies to your address before quoting.
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.
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.
Who do I deal with during the job?
One point of contact manages your project from survey to handover. They schedule the trades working under our contract, keep you updated on progress, and are the person to call with any question. You don't need to coordinate builders, electricians or decorators separately, because that is part of what we do.
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.
