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

Never tape over, bridge or bypass a safety device to make an electric roller door close.
A pressure-sensitive safety edge on the bottom rail stops or reverses the door when it touches something while closing.
Replacement safety edges and photocell pairs have fitted prices, agreed before the visit is booked.
Photocells can often be added to doors that only have a safety edge, if the control box allows it.

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 Hornchurch: questions

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 Hornchurch?

Yes. Hornchurch is part of the area we cover in Greater London, including RM12, RM11 and RM2. Get a guide price online, then we confirm a survey or visit date in writing. Dates depend on installer and engineer availability.

Do you charge more for Hornchurch than other towns in Greater London?

No. Guide prices are the same for Hornchurch as for anywhere else we cover in Greater London. 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 Hornchurch?

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 Hornchurch visit date is confirmed 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.

How do I test my safety edge and photocells?

Follow the manufacturer's instructions for your door. In general, the test checks that the door stops or reverses when the safety edge meets an obstruction while closing, and that the door won't close while the photocell beam is broken. Keep people and pets clear while testing, and repeat the test monthly.
