Never tape over, bridge or bypass a safety device to make an electric roller door close.

Wiping the photocell lenses and clearing the beam are safe checks to make before you request a visit.

Rules that apply in Denton

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 Denton: questions

Do you charge more for Denton than other towns in Greater Manchester?

No. Guide prices are the same for Denton as for anywhere else we cover in Greater Manchester. The written quote reflects your opening and the door you choose, not your postcode, apart from islands and remote areas where any travel cost is shown in advance.

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

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 Denton visit date is confirmed 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 cover Denton?

Yes. Denton is part of the area we cover in Greater Manchester, including M34, M18 and M43. Get a guide price online, then we confirm a survey or visit date in writing. Dates depend on installer and engineer availability.

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.
