What should I know about battery backup and safety upgrades in Northolt?

You're shown how to test the safety edge and photocells monthly, following the manufacturer's instructions for your door.
The battery charges from the mains while the power is on, so it's ready the next time there's a power cut.
After fitting, the door is tested to check it stops and reverses as it should with the new devices.
A battery backup unit lets the door run for a limited number of cycles when the mains power is off.

Rules that apply in Northolt

Powered door safety

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.

Battery backup and safety upgrades in Northolt: questions

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

Yes. We repair roller garage doors of any make in Northolt and across UB5, UB6 and UB1, 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.

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

No. Guide prices are the same for Northolt 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 cover Northolt?

Yes. Northolt is part of the area we cover in Greater London, including UB5, UB6 and UB1. Get a guide price online, then we confirm a survey or visit date in writing. Dates depend on installer and engineer availability.

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.

Can a battery backup be fitted to a manual roller door?

No. A manual door has no motor or control box for a battery unit to power, because springs in the barrel balance the curtain and you lift it by hand. If you'd like powered operation, a manual-to-electric conversion may be possible when the curtain, barrel, box and guides are sound and compatible.

Can safety devices be added to an older electric door?

Usually, if a compatible safety edge or photocells are available for the control box. 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 it can be done, and the price, before booking the visit.
