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

Photocells either side of the opening stop the door closing while anything is breaking the beam between them.
A pressure-sensitive safety edge on the bottom rail stops or reverses the door when it touches something while closing.
The engineer tests the whole circuit, because a damaged cable or control box fault can look like a failed device.
Photocells can often be added to doors that only have a safety edge, if the control box allows it.

Rules that apply in Warminster

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 Warminster: questions

Do you cover Warminster?

Yes. Warminster is part of the area we cover in Wiltshire, including BA12. 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 Warminster?

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 Warminster. 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 Warminster?

Yes. We repair roller garage doors of any make in Warminster and across BA12, 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 get a price for Warminster 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.

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.
