What timber and alu-clad sliding doors offer homes in Purley
These are the points a surveyor will go through with you when you choose timber and alu-clad sliding doors for a home in Purley:
Because timber and alu-clad sliding doors typically take 8–10 weeks to make, a Purley building programme runs more smoothly when the survey happens as soon as the opening size is fixed.
Where the back of a Purley 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.
- Stains, paints and lacquers are sprayed in the factory under controlled conditions, giving a more even and longer-lasting coat than a finish brushed on site.
- Scratches and dents on internal timber faces can usually be sanded and refinished locally, rather than needing a whole panel replaced.
Sunlight, glass and orientation in Purley
Sun angles matter for big glazed doors. Around Purley, 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.
How much do timber and alu-clad sliding doors cost in Purley?

How fitting works in Purley
Here is the usual sequence in Purley: guide price, free survey, written quote, then manufacture (typically 8–10 weeks from survey sign-off). Fitting typically takes 1 day for a two-panel swap; 1–2 days for larger doors. Nearby, we also survey in Coulsdon, Croydon and Carshalton.
Do you need approval in Purley?
English Building Regulations treat a new or replacement external door in an existing home as a controlled fitting: it needs a U-value of 1.4 W/m²K or better (or Doorset Energy Rating band C) if more than 60% of it is glazed (Approved Document L), and safety glass in a critical location (Approved Document K). Compliance is arranged through a competent person scheme installer or a Building Control notification, so you get a certificate for your records.
Which options matter for timber and alu-clad sliding doors?
- Sliding hardware. Inline rollers on smaller doors, or lift and slide gear for larger and heavier panels.
- Alu-cladding. A powder-coated aluminium outer shell in a standard or RAL colour, with timber left on show inside.
- Timber species. Oak or another hardwood for a visible grain, or engineered softwood where a painted finish is planned.
Questions about timber and alu-clad sliding doors in Purley
Can you match other doors and windows in my Purley 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 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.
What is the difference between timber and alu-clad sliding doors?
The difference is the outside face: a timber sliding door is wood inside and out, while an alu-clad door has a powder-coated aluminium shell fixed over the exterior timber. Alu-clad needs only washing outside and comes in any RAL colour; all-timber needs periodic re-coating but keeps a natural wood look on both faces. The inside is timber either way.
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.
