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

After fitting, the door is tested to check it stops and reverses as it should with the new devices.
We check your motor and control box are compatible with the upgrade before the visit is booked, not on the day.
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.

Rules that apply in Sevenoaks

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.

Battery backup and safety upgrades in Sevenoaks: questions

Do you cover Sevenoaks?

Yes. Sevenoaks is part of the area we cover in Kent, including TN13 and TN14. Get a guide price online, then we confirm a survey or visit date in writing. Dates depend on installer and engineer availability.

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

Yes. We repair roller garage doors of any make in Sevenoaks and across TN13 and TN14, 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.

Can I get a price for Sevenoaks 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.

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

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

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.

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.
