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

Wiping the photocell lenses and clearing the beam are safe checks to make before you request a visit.
The engineer tests the whole circuit, because a damaged cable or control box fault can look like a failed device.
Replacement safety edges and photocell pairs have fitted prices, agreed before the visit is booked.
Photocells can often be added to doors that only have a safety edge, if the control box allows it.

Safety edge and photocell repairs in Forfar: questions

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

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 Forfar visit date is confirmed in writing.

Can I message you a photo of my garage in Forfar?

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

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.

How much is a visit in Forfar?

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 Forfar as elsewhere we cover.

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.
