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.
Never tape over, bridge or bypass a safety device to make an electric roller door close.

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.

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 Darton: questions

Can I get a price for Darton 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 Darton?

Yes. Darton is part of the area we cover in South Yorkshire, including S75 and S71. 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 Darton?

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

Do you charge more for Darton than other towns in South Yorkshire?

No. Guide prices are the same for Darton as for anywhere else we cover in South Yorkshire. 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.

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.

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.
