Are timber and alu-clad sliding doors right for your Lewisham home?
A few practical points decide whether timber and alu-clad sliding doors suit a particular room and opening:
Whether you live in Lewisham or elsewhere in Greater London, an exposed coastal or hilltop elevation makes a strong case for alu-clad rather than all-timber outside.
Oak floors, exposed beams or a timber kitchen in your Lewisham home? Matching the inside finish of the door ties the new glazing into the room.
- Engineered timber is laminated from several layers with the grain opposed, so frames resist the twisting and warping that solid timber can suffer as the seasons change.
- 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.
- A timber sliding door sits comfortably beside brick, stone, render or weatherboarding, which helps where a modern metal frame would look out of character.
Planning glass for the light in Lewisham
Sun angles matter for big glazed doors. Around Lewisham, 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 fitting works in Lewisham
A surveyor visits your Lewisham home to measure the structural opening, check levels and the lintel, and talk through glass and finish. Once you confirm the written specification, the door is made to measure — typically 8–10 weeks from survey sign-off — and fitting usually takes 1 day for a two-panel swap; 1–2 days for larger doors. We also cover Blackheath (1 km north-east) and Catford (2 km south).
Rules for timber and alu-clad sliding doors in England
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.
Finishes and extras for timber and alu-clad sliding doors
- Timber species. Oak or another hardwood for a visible grain, or engineered softwood where a painted finish is planned.
- Interior finish. Clear lacquer, a wood stain or a painted colour, chosen to match floors, beams or kitchen units.
- 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 Lewisham
Is the price different in Lewisham?
No. Guide prices for timber and alu-clad sliding doors are the same across mainland Britain, including Lewisham. The fitted price depends on size, system, glass and finish, and any structural work, all fixed in your written quote 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.
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.
Are timber sliding doors secure?
Timber sliding doors are secure when built with multi-point locking, laminated glass and robust sections, because engineered timber gives the locking keeps a solid, dense fixing. Timber systems are available tested to PAS 24, the UK enhanced security test standard for doorsets. Internally beaded glass and a key-locking handle add further resistance to forced entry.
