Options for door safety upgrades in Caernarfon
- Panel upgrades. Where the old panel cannot monitor devices, we replace it with one that can.
- Photocells. If something breaks the beam, the door will not close.
- Light curtains. Full-height multi-beam detection across the whole opening.
- Fall protection. If a spring, cable or drive fails, the door is caught before it falls.
- Safety edges. Edges on the closing rail detect contact and send the door back up.
Jobs we can carry out
- Fitting a full-height light curtain to an automatic sectional door on a busy pedestrian route.
- Replacing a damaged or bypassed safety edge on a yard roller shutter and re-testing its closing forces.
- Adding warning beacons and photocells to a door that is being converted to automatic closing on a timer.
Safety law for industrial doors in Wales
Industrial doors in Caernarfon are covered by the same rules as the rest of Great Britain. On handover you should receive user instructions and, for a powered door, the conformity paperwork, because the installer is treated as the manufacturer when they assemble or motorise it. Afterwards, keeping the door in efficient working order is the occupier's job under the Workplace Regulations 1992 and PUWER 1998, which in practice means regular servicing and a written log.
Planning the work around your site
For busy sites in Gwynedd the work can be split across visits — preparation and framing first, door installation and commissioning second — so the opening is only out of action for the shortest time.

Frequently asked questions
How long does a safety upgrade take in Caernarfon?
Most upgrades take a few hours per door, including re-testing. If a new control panel is needed, it may take longer. We plan work to keep doors out of use for as short a time as possible.
Do our powered doors in Caernarfon need safety upgrades?
It depends on how they are controlled and used. Doors that close automatically or on a single press typically need edges and photocells or light curtains. A survey and force test shows whether your doors meet current expectations.
Do you upgrade doors from other installers across Gwynedd?
Yes. We upgrade safety devices on most makes of powered door across Gwynedd, whoever installed them, checking that new devices are compatible with the existing control panel and replacing the panel where needed.
