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

Photocells can often be added to doors that only have a safety edge, if the control box allows it.
After a repair, the door is tested to check it stops or reverses on obstruction before it's handed back.
Wiping the photocell lenses and clearing the beam are safe checks to make before you request a visit.
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 Helensburgh?

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 Helensburgh: 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 repair roller doors you did not fit in Helensburgh?

Yes. We repair roller garage doors of any make in Helensburgh and across G84, 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.

Can I get a price for Helensburgh 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.

Do you cover Helensburgh?

Yes. Helensburgh is part of the area we cover in Dunbartonshire and Argyll, including G84. Get a guide price online, then we confirm a survey or visit date in writing. Dates depend on installer and engineer availability.

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.

Do you repair safety devices on any make of roller door?

Yes. We repair and replace safety edges and photocells on electric roller garage doors of any make, provided compatible parts are available for the control box. We don't work on sectional or up-and-over doors. If a compatible part isn't available, we'll explain the options before anything is booked.
