Why choose external pocket sliding doors in Hertford?
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 Hertford wall is built decides how the pocket is formed, which is why the survey looks at it closely.
Want the whole width of your Hertford 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.
- 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.
- 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.
- 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.
Sunlight, glass and orientation in Hertford
Daylight in Hertford runs from about 7 h 47 min in December to 16 h 42 min in June, with the noon sun at roughly 15° and 62° respectively. Use that to choose your glass: standard low-E double glazing for north and east elevations, and consider solar-control or triple glazing for sunny south and west walls.

From survey to fitted door in Hertford
A surveyor visits your Hertford 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.
Do you need approval in Hertford?
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
- Pocket side. A single pocket to one side, or pockets on both sides so a wide door parts in the middle.
- Internal finish. Plastered, panelled or tiled finishes on the pocket wall, with the access panel set discreetly into it.
- Threshold. Low or flush thresholds, with the external drainage channel continuing past the pocket.
Questions about external pocket sliding doors in Hertford
Can you match other doors and windows in my Hertford 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.
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 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.
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.
