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

The engineer tests the whole circuit, because a damaged cable or control box fault can look like a failed device.
Photocells either side of the opening stop the door closing while anything is breaking the beam between them.
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.

Rules that apply in Caterham

Powered door safety

Every powered door we fit is commissioned with force testing to BS EN 12453 and handed over with a Declaration of Conformity and UKCA or CE marking, as the Supply of Machinery (Safety) Regulations 2008 require.

Electrics

An electric door needs a power supply near the roller box. Electrical work must meet BS 7671, and in England some domestic electrical work is notifiable under Part P, so it is done by a registered competent person or signed off by building control.

Do you cover Caterham?

How much is a visit in Caterham?

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 Caterham as elsewhere we cover.

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

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 Caterham. 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.

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.
