Are timber and alu-clad sliding doors right for your Blyth home?
A few practical points decide whether timber and alu-clad sliding doors suit a particular room and opening:
Because timber and alu-clad sliding doors typically take 8–10 weeks to make, a Blyth building programme runs more smoothly when the survey happens as soon as the opening size is fixed.
Oak floors, exposed beams or a timber kitchen in your Blyth home? Matching the inside finish of the door ties the new glazing into the room.
- Scratches and dents on internal timber faces can usually be sanded and refinished locally, rather than needing a whole panel replaced.
- 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.
- 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 Blyth
In Blyth the shortest day has roughly 7 h 08 min of daylight and the longest about 17 h 24 min. The noon sun sits near 11° above the horizon in winter and 58° in summer — so glass that faces south collects useful warmth from October to March, while a west-facing door may need solar control to stop it overheating in July.
What should you budget for timber and alu-clad sliding doors in Blyth?
Guide prices are the same across Northumberland: the fitted price depends on the size, system and specification, not your postcode. These figures are for a standard 2.1 m high door, fitted, including VAT and removal of an old door of similar size.

|---|---|---|
| 2.4 m | 2 panels | £6,495–£7,995 |

Timescales for timber and alu-clad sliding doors in Blyth
Once the opening is measured, nothing is ordered until you sign off the specification. Lead time is typically 8–10 weeks from survey sign-off. Our fitters protect floors, remove the old door, install and seal the new one and leave the area clean — usually 1 day for a two-panel swap; 1–2 days for larger doors for a door like this.
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 Blyth
Do you fit timber and alu-clad sliding doors in Blyth?
Yes. We survey and fit timber and alu-clad sliding doors in Blyth and across Northumberland, including nearby Bedlington and Ashington. Start with a guide price online or call us, and we will arrange a free survey for a new or replacement door.
Are timber sliding doors energy efficient?
Timber sliding doors are energy efficient because wood insulates naturally, and engineered timber systems typically achieve whole-door U-values comparable with good thermally broken aluminium, depending on the glass. In England, a new or replacement door in an existing home with more than 60% glazing must reach 1.4 W/m²K or better, and the glazing is specified to meet that. Wales, Scotland and Northern Ireland set their own energy rules.
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.
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.
