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

After a repair, the door is tested to check it stops or reverses on obstruction before it's handed back.
Never tape over, bridge or bypass a safety device to make an electric roller door close.
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.

Rules that apply in Islington

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 Islington: questions

Will you fix the door on the first visit?

A fault can sometimes be found and put right on the first visit, but we never promise it. If a part needs ordering, we quote for it first, make the door safe where we can, and confirm the return date in writing.

Do you cover Islington?

Yes. Islington is part of the area we cover in Greater London, including N1, N1C and N5. 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 Islington?

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

How much is a visit in Islington?

Prices for safety edge and photocell repairs start from £99 inc VAT, and the price is agreed before anyone comes out. Any parts not covered by that price are quoted before they are fitted, so you can decide on the spot. The guide prices are the same in Islington as elsewhere we cover.

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.
