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

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.
Photocells can often be added to doors that only have a safety edge, if the control box allows it.
After a repair, the door is tested to check it stops or reverses on obstruction before it's handed back.

How does it work in Hatfield?

The engineer tests the circuit and replaces the faulty device, then tests the door. Any further parts are quoted before they're fitted.

Rules that apply in Hatfield

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 Hatfield: questions

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

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 Hatfield visit date is confirmed in writing.

Do you cover Hatfield?

Yes. Hatfield is part of the area we cover in Hertfordshire, including AL10, AL9 and AL7. Get a guide price online, then we confirm a survey or visit date in writing. Dates depend on installer and engineer availability.

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

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

Do you charge more for Hatfield than other towns in Hertfordshire?

No. Guide prices are the same for Hatfield as for anywhere else we cover in Hertfordshire. 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 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.
