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

After a repair, the door is tested to check it stops or reverses on obstruction before it's handed back.
Wiping the photocell lenses and clearing the beam are safe checks to make before you request a visit.
A pressure-sensitive safety edge on the bottom rail stops or reverses the door when it touches something while closing.
The engineer tests the whole circuit, because a damaged cable or control box fault can look like a failed device.

How does it work in Potters Bar?

The engineer tests the circuit and replaces the faulty device, then tests the door. Any further parts are quoted before they're fitted.

Rules that apply in Potters Bar

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 England 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 Potters Bar: questions

Can I message you a photo of my garage in Potters Bar?

Yes. Photos of the opening, the inside of the garage above the door and any existing door help us give a more useful guide price for Potters Bar. Send them by WhatsApp or mention them in your enquiry, and we will reply in writing.

Can I get a price for Potters Bar 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 cover Potters Bar?

Yes. Potters Bar is part of the area we cover in Hertfordshire, including EN6. Get a guide price online, then we confirm a survey or visit date in writing. Dates depend on installer and engineer availability.

Do you repair roller doors you did not fit in Potters Bar?

Yes. We repair roller garage doors of any make in Potters Bar and across EN6, where parts are available. If a part is no longer made, we tell you what will fit instead, or price a replacement door if that is the better option.

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.

Can I bypass the photocells to get the door shut?

No. Bypassing, bridging or taping over a safety device removes the protection that stops the door closing onto a person, pet or car. If the door won't close, switch it off at the isolator, keep the area clear and request a visit. Tell us if you're concerned about security when you get in touch.
