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

A battery backup unit lets the door run for a limited number of cycles when the mains power is off.
You're shown how to test the safety edge and photocells monthly, following the manufacturer's instructions for your door.
After fitting, the door is tested to check it stops and reverses as it should with the new devices.
Where a door has never had photocells, any extra wiring needed is priced before we come out.

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 Bexleyheath: questions

Can I get a price for Bexleyheath 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 Bexleyheath?

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

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

No. Guide prices are the same for Bexleyheath 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.

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.

How many times will a battery backup open the door?

It depends on the unit, the motor and the size and weight of the door. A battery backup is designed for a limited number of cycles in a power cut, not for running the door for days. If you need the door after the battery runs down, use the manual override as the manufacturer's instructions describe.

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.
