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

Photocells either side of the opening stop the door closing while anything is breaking the beam between them.
Wiping the photocell lenses and clearing the beam are safe checks to make before you request a visit.
After a repair, the door is tested to check it stops or reverses on obstruction before it's handed back.
Photocells can often be added to doors that only have a safety edge, if the control box allows it.

How does it work in St Austell?

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

Safety edge and photocell repairs in St Austell: questions

Do you cover St Austell?

Yes. St Austell is part of the area we cover in Cornwall, including PL25, PL26 and PL24. Get a guide price online, then we confirm a survey or visit date in writing. Dates depend on installer and engineer availability.

Can I get a price for St Austell without anyone visiting?

How much is a visit in St Austell?

Prices for safety edge and photocell repairs start from £99 inc VAT, and the price is agreed before anyone comes out. Any parts not covered by that price are quoted before they are fitted, so you can decide on the spot. The guide prices are the same in St Austell as elsewhere we cover.

What should I do while I wait for a visit in St Austell?

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 St Austell visit date is confirmed in writing.

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.
