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

We check your motor and control box are compatible with the upgrade before the visit is booked, not on the day.
The battery charges from the mains while the power is on, so it's ready the next time there's a power cut.
Where a door has never had photocells, any extra wiring needed is priced before we come out.
A battery backup unit lets the door run for a limited number of cycles when the mains power is off.

How does it work in Weymouth?

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 Weymouth

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 Weymouth: questions

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

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 Weymouth visit date is confirmed in writing.

Do you charge more for Weymouth than other towns in Dorset?

No. Guide prices are the same for Weymouth as for anywhere else we cover in Dorset. 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.

How much is a visit in Weymouth?

Prices for battery backup and safety upgrades 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 Weymouth as elsewhere we cover.

Do you cover Weymouth?

Yes. Weymouth is part of the area we cover in Dorset, including DT4 and DT3. Get a guide price online, then we confirm a survey or visit date in writing. Dates depend on installer and engineer availability.

Do I still need the manual override if I have a battery backup?

Yes. A battery unit covers a limited number of cycles, and it can run down during a long power cut or as the battery ages. Keep the override handle somewhere you can find it in the dark, and make sure everyone who uses the garage knows where it is and how it works.

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.
