Why choose external pocket sliding doors in Cobham?
A few practical points decide whether external pocket sliding doors suit a particular room and opening:
Solid brick, cavity block or timber frame: the way your Cobham wall is built decides how the pocket is formed, which is why the survey looks at it closely.
If the wall beside your Cobham patio opening is free of windows, radiators and sockets, it may be long enough to take a pocket so the panels disappear completely.
- Insulating the pocket wall and sealing the panel edges limits heat loss through the cavity, helping the wall beside the door perform like the rest of the house.
- A removable access panel on the inside of the pocket wall lets the rollers be reached and adjusted without opening up the plaster.
- Pockets can be formed on one side or both, so a wide opening can part in the middle with panels sliding away in each direction.
Light and sun in Cobham
Sun angles matter for big glazed doors. Around Cobham, midday sun reaches about 62° in summer and drops to about 15° in winter. That low winter sun is free heat through south-facing glass; high summer sun is easier to shade with a roof overhang, and solar-control glass helps where there is none.

Timescales for external pocket sliding doors in Cobham
A surveyor visits your Cobham home to check the wall, the structure above and the floor levels, and talks through glass and finish. Any building work is planned to the engineer's design, the door is made to the finished opening sizes — typically 6–8 weeks from survey sign-off — and fitting usually takes 3–5 days of building work to form the opening and pocket, then 1–2 days to fit the door.
Rules for external pocket sliding doors in England
A new or wider opening in England needs Building Control approval for the structural work as well as compliance for the door itself under Approved Documents L and K. Expect structural calculations, a steel beam and, where a party wall is involved, notices under the Party Wall etc. Act 1996.
Specification choices for external pocket sliding doors in Cobham
- Internal finish. Plastered, panelled or tiled finishes on the pocket wall, with the access panel set discreetly into it.
- Colours. Single or dual colour powder coating, so the exposed edge of the panel matches the frame inside and out.
- Glass. Double or triple glazed safety glass, with laminated or solar-control units as needed.
Questions about external pocket sliding doors in Cobham
How soon can you survey in Cobham?
Surveys in the KT11 district are booked at a time that suits you, and we offer survey dates when we reply to your enquiry. After you approve the written quote, manufacture is typically 6–8 weeks from survey sign-off.
How wide can an external pocket sliding door be?
An external pocket sliding door in our range typically gives a clear opening of about 1.8 m to 6 m, using one panel at the narrow end and two or three panels on wider doors. Wider openings usually use pockets on both sides, or a multi-track pocket so the panels stack inside the wall. Sizes are confirmed after survey and the engineer's design.
How much wall do I need for an external pocket door?
An external pocket door needs a clear length of wall beside the opening at least as long as the panels that slide into it, plus a little for the frame. For a single 2 m panel that means just over 2 m of wall with no windows, radiators, sockets or pipes in it. A two-sided pocket splits the panels between both sides, so each side needs less length.
How much do external pocket sliding doors cost?
External pocket sliding doors start from a guide price of £6,595 for a 1.8 m single-panel door, fitted, inc VAT, at standard 2.1 m height, including forming the wall pocket. A 3 m two-panel door is a guide £8,395–£10,295, and a 6 m three-panel door is around £12,895. Wall construction, glass and finish affect the figure, which is fixed in a written quote after survey.
