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

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.
Replacement safety edges and photocell pairs have fitted prices, agreed before the visit is booked.
After a repair, the door is tested to check it stops or reverses on obstruction before it's handed back.

How does it work in Plymouth?

We confirm the visit price and the likely part before anything is booked. The visit date depends on engineer availability and is confirmed in writing.

Rules that apply in Plymouth

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 Plymouth: questions

Can I get a price for Plymouth without anyone visiting?

Yes. The guide price tool takes four steps and gives a range for your opening and door type. It is a guide, not a quote: the written quote comes after the survey or once the visit price is agreed.

Do you cover Plymouth?

Yes. Plymouth is part of the area we cover in Devon, including PL4, PL1 and PL3. 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 Plymouth?

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 Plymouth visit date is confirmed in writing.

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

Yes. We repair roller garage doors of any make in Plymouth and across PL4, PL1 and PL3, 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.

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.
