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

Replacement safety edges and photocell pairs have fitted prices, agreed before the visit is booked.
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.

Safety edge and photocell repairs in Dunoon: questions

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 Dunoon?

Yes. Dunoon is part of the area we cover in Dunbartonshire and Argyll, including PA23. 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 Dunoon?

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

Can I get a price for Dunoon 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.
