External pocket sliding doors in Crawley: what to know
These are the points a surveyor will go through with you when you choose external pocket sliding doors for a home in Crawley:
Want the whole width of your Crawley kitchen open to the garden but prefer the look of sliders to bifolds? A pocket gives you both, at the cost of more building work.
For a Crawley extension still at the drawing stage, planning the pocket wall now is far simpler than rebuilding a finished wall later.
- 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.
- With every panel slid into the wall, the full width of the opening is clear, so the room and terrace join without a fixed panel in the way.
- A removable access panel on the inside of the pocket wall lets the rollers be reached and adjusted without opening up the plaster.
Sunlight, glass and orientation in Crawley
Sun angles matter for big glazed doors. Around Crawley, 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.
Guide prices for external pocket sliding doors in Crawley

What happens when you order external pocket sliding doors in Crawley?
Nothing is ordered until you sign off the surveyed specification. The door is made from 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. If you are in Horley or Horsham, the same process and prices apply.
Do you need approval in Crawley?
In England, forming or widening an opening is structural work that needs a Building Regulations application, structural calculations and usually a steel beam on padstones. The new door is also a controlled fitting (U-value 1.4 W/m²K or better if more than 60% glazed). If steelwork bears on a party wall, the Party Wall etc. Act 1996 may apply.
Choosing the specification
- Colours. Single or dual colour powder coating, so the exposed edge of the panel matches the frame inside and out.
- System type. Standard aluminium, slimline or lift and slide pocket systems, chosen to suit panel weight and sightlines.
- Threshold. Low or flush thresholds, with the external drainage channel continuing past the pocket.
Questions about external pocket sliding doors in Crawley
Do I need building approval for external pocket sliding doors in Crawley?
In England a replacement door is a controlled fitting, so compliance is arranged through a competent person scheme installer or Building Control; new openings need a Building Regulations application. We confirm the right route for your property at survey, so the paperwork is in place before fitting.
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 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.
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.
