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

Never tape over, bridge or bypass a safety device to make an electric roller door close.
Wiping the photocell lenses and clearing the beam are safe checks to make before you request a visit.
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 Blackheath?

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 Blackheath

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 Blackheath: questions

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

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 Blackheath visit date is confirmed in writing.

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

No. Guide prices are the same for Blackheath 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.

Do you repair roller doors you did not fit in Blackheath?

Yes. We repair roller garage doors of any make in Blackheath and across SE3, SE13 and SE10, 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.

How much is a visit in Blackheath?

Prices for safety edge and photocell repairs start from £99 inc VAT, and the price is agreed before anyone comes out. Any parts not covered by that price are quoted before they are fitted, so you can decide on the spot. The guide prices are the same in Blackheath as elsewhere we cover.

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.

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.
