What should I know about safety edge and photocell repairs in Llangefni?

After a repair, the door is tested to check it stops or reverses on obstruction before it's handed back.
The engineer tests the whole circuit, because a damaged cable or control box fault can look like a failed device.
Never tape over, bridge or bypass a safety device to make an electric roller door close.
Photocells either side of the opening stop the door closing while anything is breaking the beam between them.

Rules that apply in Llangefni

Powered door safety

Every powered door we fit is commissioned with force testing to BS EN 12453 and handed over with a Declaration of Conformity and UKCA or CE marking, as the Supply of Machinery (Safety) Regulations 2008 require.

Electrics

An electric door needs a power supply near the roller box. Electrical work must meet BS 7671, and in Wales some domestic electrical work is notifiable under Part P, so it is done by a registered competent person or signed off by building control.

Safety edge and photocell repairs in Llangefni: questions

How much is a visit in Llangefni?

Prices for safety edge and photocell repairs start from £99 inc VAT, agreed before anyone comes out, and any extra parts are quoted before they are fitted. Because of travel, visits to Llangefni are arranged individually and any travel charge is confirmed in writing before the visit is booked.

Can I get a price for Llangefni without anyone visiting?

Yes. The guide price tool takes four steps and gives a range for your opening and door type. It is a guide, not a quote: the written quote comes after the survey or once the visit price is agreed.

Do you charge more for Llangefni?

How do I test my safety edge and photocells?

Follow the manufacturer's instructions for your door. In general, the test checks that the door stops or reverses when the safety edge meets an obstruction while closing, and that the door won't close while the photocell beam is broken. Keep people and pets clear while testing, and repeat the test monthly.

Do you repair safety devices on any make of roller door?

Yes. We repair and replace safety edges and photocells on electric roller garage doors of any make, provided compatible parts are available for the control box. We don't work on sectional or up-and-over doors. If a compatible part isn't available, we'll explain the options before anything is booked.
