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

Photocells either side of the opening stop the door closing while anything is breaking the beam between them.
After a repair, the door is tested to check it stops or reverses on obstruction before it's handed back.
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.

How does it work in Walthamstow?

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

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

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

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.

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.
