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

Never tape over, bridge or bypass a safety device to make an electric roller door close.
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.
Wiping the photocell lenses and clearing the beam are safe checks to make before you request a visit.

How does it work in Johnstone?

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

An electric door needs a power supply near the roller box. Part P does not apply in Scotland, but electrical work must meet BS 7671 and the Scottish building standards where it forms part of building work.

Safety edge and photocell repairs in Johnstone: questions

Can I get a price for Johnstone 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 I message you a photo of my garage in Johnstone?

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

Do you charge more for Johnstone than other towns in Renfrewshire and Inverclyde?

No. Guide prices are the same for Johnstone as for anywhere else we cover in Renfrewshire and Inverclyde. 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.

Do you cover Johnstone?

Yes. Johnstone is part of the area we cover in Renfrewshire and Inverclyde, including PA5, PA10 and PA9. Get a guide price online, then we confirm a survey or visit date in writing. Dates depend on installer and engineer availability.

Can I bypass the photocells to get the door shut?

No. Bypassing, bridging or taping over a safety device removes the protection that stops the door closing onto a person, pet or car. If the door won't close, switch it off at the isolator, keep the area clear and request a visit. Tell us if you're concerned about security when you get in touch.

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.
