Why choose timber and alu-clad sliding doors in Welwyn Garden City?
These are the points a surveyor will go through with you when you choose timber and alu-clad sliding doors for a home in Welwyn Garden City:
Because timber and alu-clad sliding doors typically take 8–10 weeks to make, a Welwyn Garden City building programme runs more smoothly when the survey happens as soon as the opening size is fixed.
For a listed building or a house in a conservation area in Welwyn Garden City, check with the local planning authority before choosing any new door; timber frames are often closer in character to the original joinery.
- Wood is a natural insulator, so timber frames feel warm to the touch in winter and help keep condensation off the inside face of the frame.
- The inside face can be finished to match existing oak floors, stair parts or window boards, so the new door feels part of the room rather than an addition.
- Many timber systems use lift and slide hardware, letting large, heavy panels glide easily and then settle onto compressed seals for a tight closure.
How much sun will a door in Welwyn Garden City get?
Daylight in Welwyn Garden City runs from about 7 h 46 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 Welwyn Garden City
Surveys in the AL8 district are booked at a time that suits you. After you approve the quote, manufacture is typically 8–10 weeks from survey sign-off; on fitting day the old door comes out, the new frame is set level and sealed, and the panels are adjusted so they glide properly. Fitting usually takes 1 day for a two-panel swap; 1–2 days for larger doors.
Rules for timber and alu-clad sliding doors in England
In England, a replacement sliding door is a controlled fitting under the Building Regulations. In an existing home, a door with more than 60% glazing must reach a U-value of 1.4 W/m²K or better (or a Doorset Energy Rating of band C) under Approved Document L, and glass in doors must be safety glazing under Approved Document K. We arrange compliance through a competent person scheme installer or by notifying Building Control, and you receive the certificate.

Questions about timber and alu-clad sliding doors in Welwyn Garden City
Do I need building approval for timber and alu-clad sliding doors in Welwyn Garden City?
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.
Can I fit timber sliding doors to a listed building or in a conservation area?
Timber sliding doors can suit listed buildings and conservation areas, but listed buildings and properties under an Article 4 direction may need consent before any door is changed, so check with your local planning authority first. In England, replacing doors on an ordinary house with similar-looking ones is usually permitted development. Wales, Scotland and Northern Ireland have their own planning rules.
How big can a timber sliding door be?
A timber sliding door in our range is typically about 1.5 m to 4.8 m wide overall, in two to four panels, at standard 2.1 m height or taller on request. Individual panel sizes depend on the system and glass weight; larger panels usually move to lift and slide hardware so they stay easy to open. Sizes are confirmed after survey.
How long do timber sliding doors take to make?
Timber and alu-clad sliding doors typically take 8–10 weeks to make after survey sign-off, longer than metal or uPVC, because each door is joinery-made, factory finished and allowed to cure before delivery. Fitting typically takes 1 day for a two-panel swap and 1–2 days for larger doors. These are typical timescales, confirmed once your order is placed.
