What should I know about safety edge and photocell repairs in Sunbury-on-Thames?

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.
Photocells either side of the opening stop the door closing while anything is breaking the beam between them.
Never tape over, bridge or bypass a safety device to make an electric roller door close.

Safety edge and photocell repairs in Sunbury-on-Thames: questions

Do you charge more for Sunbury-on-Thames than other towns in Surrey?

No. Guide prices are the same for Sunbury-on-Thames as for anywhere else we cover in Surrey. 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.

Can I get a price for Sunbury-on-Thames 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.

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.

Do you cover Sunbury-on-Thames?

Yes. Sunbury-on-Thames is part of the area we cover in Surrey, including TW16, TW17 and TW15. Get a guide price online, then we confirm a survey or visit date in writing. Dates depend on installer and engineer availability.

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.

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.
