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

A battery backup unit lets the door run for a limited number of cycles when the mains power is off.
Where a door has never had photocells, any extra wiring needed is priced before we come out.
We check your motor and control box are compatible with the upgrade before the visit is booked, not on the day.
After fitting, the door is tested to check it stops and reverses as it should with the new devices.

How does it work in Nailsea?

On the day, the upgrade is fitted and the door is tested. If anything else needs attention, the parts are quoted before they're fitted.

Rules that apply in Nailsea

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 Nailsea: questions

Do you charge more for Nailsea than other towns in Somerset?

No. Guide prices are the same for Nailsea as for anywhere else we cover in Somerset. 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 Nailsea?

Yes. We repair roller garage doors of any make in Nailsea and across BS48, 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.

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

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 Nailsea visit date is confirmed in writing.

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

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