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

A pressure-sensitive safety edge on the bottom rail stops or reverses the door when it touches something while closing.
Photocells either side of the opening stop the door closing while anything is breaking the beam between them.
Never tape over, bridge or bypass a safety device to make an electric roller door close.
Replacement safety edges and photocell pairs have fitted prices, agreed before the visit is booked.

Rules that apply in Christchurch

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 Christchurch: questions

Do you charge more for Christchurch than other towns in Dorset?

No. Guide prices are the same for Christchurch as for anywhere else we cover in Dorset. 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.

Do you cover Christchurch?

Yes. Christchurch is part of the area we cover in Dorset, including BH23, BH6 and BH7. 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 Christchurch?

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 Christchurch 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.

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.

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.
