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

A pressure-sensitive safety edge on the bottom rail stops or reverses the door when it touches something while closing.
Photocells either side of the opening stop the door closing while anything is breaking the beam between them.
The engineer tests the whole circuit, because a damaged cable or control box fault can look like a failed device.
Wiping the photocell lenses and clearing the beam are safe checks to make before you request a visit.

Powered door safety

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 Sidcup: questions

How much is a visit in Sidcup?

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 Sidcup as elsewhere we cover.

Do you cover Sidcup?

Yes. Sidcup is part of the area we cover in Greater London, including DA14, DA15 and DA5. Get a guide price online, then we confirm a survey or visit date in writing. Dates depend on installer and engineer availability.

What should I do while I wait for a visit in Sidcup?

If the door is stuck part-open, keep people, pets and cars clear of it and switch off the power at the isolator if it is safe to reach. Do not force the curtain or open the roller box. Your Sidcup visit date is confirmed in writing.

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

Yes. We repair roller garage doors of any make in Sidcup and across DA14, DA15 and DA5, 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 photocells be added to a door that doesn't have them?

Often, if the control box has a connection for them. Some older systems need extra wiring or a replacement control box first. Tell us what's on the control box label and we'll confirm whether photocells can be added, and the price, before booking. Our battery backup and safety upgrades page covers adding devices.

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.
