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

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

Rules that apply in Morden

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.

Safety edge and photocell repairs in Morden: questions

Do you cover Morden?

Yes. Morden is part of the area we cover in Greater London, including SM4, SM3 and SM1. 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 Morden?

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 Morden visit date is confirmed in writing.

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

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 Morden. 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.

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.

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.
