Is a timber and alu-clad sliding door a good fit for your home in Castle Douglas?
These are the points a surveyor will go through with you when you choose timber and alu-clad sliding doors for a home in Castle Douglas:
For a listed building or a house in a conservation area in Castle Douglas, 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 Castle Douglas 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.
- Scratches and dents on internal timber faces can usually be sanded and refinished locally, rather than needing a whole panel replaced.
- A timber sliding door sits comfortably beside brick, stone, render or weatherboarding, which helps where a modern metal frame would look out of character.
- 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.
Planning glass for the light in Castle Douglas
In Castle Douglas the shortest day has roughly 7 h 11 min of daylight and the longest about 17 h 22 min. The noon sun sits near 12° 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 happens when you order timber and alu-clad sliding doors in Castle Douglas?
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.
Do you need approval in Castle Douglas?
Scottish building standards still apply to a replacement door even where no warrant is needed, so the door must meet the energy and safety glazing requirements. If the opening is being formed or widened, a building warrant is required before work begins.
Specification choices for timber and alu-clad sliding doors in Castle Douglas
- Glass. Double or triple glazed safety glass, with slim glazing bars available for a period look.
- 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 Castle Douglas
Is the price different in Castle Douglas?
No. Guide prices for timber and alu-clad sliding doors are the same across mainland Britain, including Castle Douglas. The fitted price depends on size, system, glass and finish, and any structural work, all fixed in your written quote after survey.
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.
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.
How often do timber sliding doors need treating?
Timber sliding doors need the outside re-coated every few years, depending on how exposed the elevation is and which finish system is used; doors facing full sun or coastal weather need attention soonest. Alu-clad doors avoid this, needing only an occasional wash outside. Inside, timber only needs wiping and an occasional refresh of the lacquer or oil, and a clean track protects the rollers.
