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

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.
A pressure-sensitive safety edge on the bottom rail stops or reverses the door when it touches something while closing.
After a repair, the door is tested to check it stops or reverses on obstruction before it's handed back.

Rules that apply in Colchester

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 Colchester: questions

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

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 Colchester. Send them by WhatsApp or mention them in your enquiry, and we will reply in writing.

Do you cover Colchester?

Yes. Colchester is part of the area we cover in Essex, including CO1, CO2 and CO4. Get a guide price online, then we confirm a survey or visit date in writing. Dates depend on installer and engineer availability.

Can I get a price for Colchester 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.

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.

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.

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.
