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

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.
The engineer tests the whole circuit, because a damaged cable or control box fault can look like a failed device.

Safety edge and photocell repairs in Finchley: questions

Do you repair roller doors you did not fit in Finchley?

Yes. We repair roller garage doors of any make in Finchley and across N3, N12 and N2, 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.

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 Finchley?

Yes. Finchley is part of the area we cover in Greater London, including N3, N12 and N2. Get a guide price online, then we confirm a survey or visit date in writing. Dates depend on installer and engineer availability.

What should I do while I wait for a visit in Finchley?

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 Finchley visit date is confirmed in writing.

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.

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.
