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

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

Rules that apply in Barnet

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 Barnet: questions

Do you charge more for Barnet than other towns in Greater London?

No. Guide prices are the same for Barnet as for anywhere else we cover in Greater London. The written quote reflects your opening and the door you choose, not your postcode, apart from islands and remote areas where any travel cost is shown in advance.

Do you cover Barnet?

Yes. Barnet is part of the area we cover in Greater London, including EN5, EN4 and N20. Get a guide price online, then we confirm a survey or visit date in writing. Dates depend on installer and engineer availability.

Can I message you a photo of my garage in Barnet?

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 Barnet. Send them by WhatsApp or mention them in your enquiry, and we will reply in writing.

Do you repair roller doors you did not fit in Barnet?

Yes. We repair roller garage doors of any make in Barnet and across EN5, EN4 and N20, 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.

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.

Why does my roller door reverse when nothing is in the way?

A door that reverses on its own while closing is often reacting to a safety device that thinks there's an obstruction. Dirty or misaligned photocells, a damaged safety edge, a loose cable or limits that have drifted can all cause it. Clean the photocell lenses and check the beam is clear, then request a visit if it continues.
