Sliding doors we fit in Caernarfon
Prices are the same across Gwynedd; each page explains what to expect in Caernarfon.
Daylight in Caernarfon and what it means for your glass
In Caernarfon the shortest day has roughly 7 h 32 min of daylight and the longest about 16 h 58 min. The noon sun sits near 13° above the horizon in winter and 60° 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 after you enquire
In Caernarfon the process is simple: guide price, free survey, written quote, manufacture and fitting, with the compliance certificate sent to you. Nothing is ordered until you confirm the surveyed specification in writing.
Approvals 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.
Sliding doors in Caernarfon: questions
Can you widen my opening in Caernarfon?
Yes. We can form or widen an opening for a larger sliding door, with structural calculations, a steel beam and Welsh approvals arranged. That work is quoted alongside the door.
Which sliding door suits a home in Caernarfon?
It depends on the opening and budget. uPVC is the lowest-cost option for openings up to about 3.6 m; aluminium gives slimmer frames and wider spans; slimline and lift and slide suit large, high-end openings. The survey in Caernarfon is the place to settle it.
Who fits the doors in Caernarfon?
Doors are fitted by installers we appoint and manage under our contract, so your contract and guarantees stay with us. The same surveyed specification goes from the quote to the factory to the fitters.
