Is a timber and alu-clad sliding door a good fit for your home in Porthmadog?
These are the points a surveyor will go through with you when you choose timber and alu-clad sliding doors for a home in Porthmadog:
If your Porthmadog home is a period property or a barn conversion, timber and alu-clad sliding doors can bring in more light without the modern look of a metal frame.
Whether you live in Porthmadog or elsewhere in Gwynedd, an exposed coastal or hilltop elevation makes a strong case for alu-clad rather than all-timber outside.
- 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.
- 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.
Planning glass for the light in Porthmadog
Daylight in Porthmadog runs from about 7 h 34 min in December to 16 h 55 min in June, with the noon sun at roughly 14° and 61° respectively. Use that to choose your glass: standard low-E double glazing for north and east elevations, and consider solar-control or triple glazing for sunny south and west walls.

Rules for timber and alu-clad sliding doors in Wales
In Wales, replacement doors are covered by the Building Regulations as applied in Wales, including the Welsh Part L energy requirements and safety glazing rules. Compliance is arranged through a competent person scheme installer or your council's Building Control, and the certificate is kept with your property records.
Choosing the specification
- Sliding hardware. Inline rollers on smaller doors, or lift and slide gear for larger and heavier panels.
- 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.
Questions about timber and alu-clad sliding doors in Porthmadog
Do you fit timber and alu-clad sliding doors in Porthmadog?
Yes. We survey and fit timber and alu-clad sliding doors in Porthmadog and across Gwynedd, including nearby Pwllheli and Caernarfon. Start with a guide price online or call us, and we will arrange a free survey for a new or replacement door.
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.
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.
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.
