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

Photocells can often be added to doors that only have a safety edge, if the control box allows it.
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.
A pressure-sensitive safety edge on the bottom rail stops or reverses the door when it touches something while closing.

How does it work in Harlow?

Rules that apply in Harlow

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.

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 Harlow: questions

Do you charge more for Harlow than other towns in Essex?

No. Guide prices are the same for Harlow as for anywhere else we cover in Essex. 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.

Can I get a price for Harlow 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 repair roller doors you did not fit in Harlow?

Yes. We repair roller garage doors of any make in Harlow and across CM20, CM18 and CM17, 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.

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

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 Harlow visit date is confirmed in writing.

Can photocells be added to a door that doesn't have them?

Often, if the control box has a connection for them. Some older systems need extra wiring or a replacement control box first. Tell us what's on the control box label and we'll confirm whether photocells can be added, and the price, before booking. Our battery backup and safety upgrades page covers adding devices.

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.
