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

A pressure-sensitive safety edge on the bottom rail stops or reverses the door when it touches something while closing.
Never tape over, bridge or bypass a safety device to make an electric roller door close.
Photocells can often be added to doors that only have a safety edge, if the control box allows it.
The engineer tests the whole circuit, because a damaged cable or control box fault can look like a failed device.

Rules that apply in Coulsdon

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 Coulsdon: questions

Do you cover Coulsdon?

Yes. Coulsdon is part of the area we cover in Greater London, including CR5, CR8 and SM7. Get a guide price online, then we confirm a survey or visit date in writing. Dates depend on installer and engineer availability.

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

No. Guide prices are the same for Coulsdon 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.

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

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 Coulsdon visit date is confirmed in writing.

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.

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.
