Are timber and alu-clad sliding doors right for your Portsmouth home?
These are the points a surveyor will go through with you when you choose timber and alu-clad sliding doors for a home in Portsmouth:
For a listed building or a house in a conservation area in Portsmouth, check with the local planning authority before choosing any new door; timber frames are often closer in character to the original joinery.
Where the back of a Portsmouth home faces south and takes full sun, choosing alu-clad keeps the timber protected and cuts out the re-coating that strong sunlight makes necessary.
- 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.
- Scratches and dents on internal timber faces can usually be sanded and refinished locally, rather than needing a whole panel replaced.
- An alu-clad exterior shields the wood from rain and sunlight, so the outside needs only washing while the inside keeps a natural timber finish.
Light and sun in Portsmouth

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.
Choosing the specification
- Timber species. Oak or another hardwood for a visible grain, or engineered softwood where a painted finish is planned.
- Alu-cladding. A powder-coated aluminium outer shell in a standard or RAL colour, with timber left on show inside.
- Sliding hardware. Inline rollers on smaller doors, or lift and slide gear for larger and heavier panels.
Questions about timber and alu-clad sliding doors in Portsmouth
Do I need building approval for timber and alu-clad sliding doors in Portsmouth?
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 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 much do timber sliding doors cost?
Timber and alu-clad sliding doors start from a guide price of £5,095 for a 1.5 m two-panel door, fitted, inc VAT, at standard 2.1 m height. A 2.4 m door is a guide £6,495–£7,995, and a 4.8 m four-panel door is around £10,395. Species, cladding, finish and glass all affect the figure, and the final price is fixed in a written quote after survey.
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.
