Are secure sliding doors right for homes in Gwynedd?
Here is what to weigh up if you are considering secure sliding doors for a home in Gwynedd:
Ask your insurer whether a tested door or particular locks are a requirement on your Gwynedd policy, so the quote can be specified to suit.
Whichever door you choose for your Gwynedd home, pair it with good habits: lock the door, remove the key and keep side gates bolted.
- Laminated glass has a tough interlayer that holds the pane together when struck, so even a cracked panel resists an attempt to break through.
- A doorset tested to PAS 24 has resisted a defined set of timed attacks using hand tools, giving an objective benchmark rather than a claim based on the look of the hardware.
- Robust interlocks where the panels meet reduce the chance of the door being levered open at the overlap, which is where a sliding door is often probed first.

Questions about secure sliding doors in Gwynedd
Can you match other doors and windows in my Gwynedd home?
Usually, yes. Most aluminium and uPVC systems come in standard RAL colours and finishes, and we can quote dual colour where the inside and outside need to differ. Bring photos of existing frames to the survey.
What is PAS 24?
PAS 24 is the UK enhanced security test standard for doorsets, including sliding doors. A door tested to it has been subjected to timed manual attacks with hand tools, mechanical loading of the panels and locks, and tests on how the glass is held. It applies to the complete doorset as tested, not to individual handles or locks on their own.
Can I upgrade the locks on my existing sliding door?
Sometimes, but upgrading locks alone does not turn an old door into a tested one. A new anti-snap cylinder or a secondary bolt can improve security on a sound door, and our sliding door repairs page covers lock work. If the panel can be lifted out or the glass removed from outside, replacement is usually the better answer.
How do anti-lift devices work on a sliding door?
Anti-lift devices are blocks or bolts fitted in the head of the frame or on the sliding panel that fill the gap above the panel when the door is closed. Without them, some older sliding panels could be lifted up and out of the bottom track. With them, the panel cannot be raised far enough to clear the track.
