What external pocket sliding doors offer homes in Finchley
A few practical points decide whether external pocket sliding doors suit a particular room and opening:
For a Finchley extension still at the drawing stage, planning the pocket wall now is far simpler than rebuilding a finished wall later.
If the wall beside your Finchley patio opening is free of windows, radiators and sockets, it may be long enough to take a pocket so the panels disappear completely.
- Open panels are hidden inside the wall rather than stacked in view, keeping the opening clean-lined compared with a bifold stack at one side.
- When closed, a pocket door looks like a large-paned slider, with slim meeting stiles and plenty of glass instead of the many frames of a folding door.
- 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.
Light and sun in Finchley
At the latitude of Finchley, the midday sun climbs to about 62° in late June but only about 15° in late December, when daylight lasts around 7 h 49 min against 16 h 39 min in midsummer. A south-facing external pocket sliding door lets that low winter sun deep into the room; on a west or south elevation, solar-control glass keeps summer afternoons comfortable.

From survey to fitted door in Finchley
Here is the usual sequence in Finchley: guide price, free survey, written quote, any building work, then manufacture (typically 6–8 weeks from survey sign-off). Fitting typically takes 3–5 days of building work to form the opening and pocket, then 1–2 days to fit the door. Nearby, we also survey in Hendon, Mill Hill and Golders Green.
Do you need approval in Finchley?
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.
Options to consider for your external pocket sliding door
- 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 Finchley
Can you match other doors and windows in my Finchley home?
Usually, yes. Most aluminium and uPVC systems come in standard RAL colours and finishes, and we can quote dual colour where the inside and outside need to differ. Bring photos of existing frames to the survey.
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.
Does a pocket in the wall cause heat loss?
A pocket in the wall does not have to cause significant heat loss if it is insulated, lined and sealed as part of the design, and the door itself typically achieves whole-door U-values around 1.2–1.6 W/m²K double glazed. In England, a new door in an existing home with more than 60% glazing must achieve 1.4 W/m²K or better. Wales, Scotland and Northern Ireland have their own energy rules.
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.
