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

Photocells can often be added to doors that only have a safety edge, if the control box allows it.
Photocells either side of the opening stop the door closing while anything is breaking the beam between them.
After a repair, the door is tested to check it stops or reverses on obstruction before it's handed back.
A pressure-sensitive safety edge on the bottom rail stops or reverses the door when it touches something while closing.

How does it work in Redruth?

The engineer tests the circuit and replaces the faulty device, then tests the door. Any further parts are quoted before they're fitted.

Powered door safety

Safety edge and photocell repairs in Redruth: questions

Can I message you a photo of my garage in Redruth?

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

Yes. We repair roller garage doors of any make in Redruth and across TR16 and TR15, 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.

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

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 Redruth visit date is confirmed in writing.

Do you cover Redruth?

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.
