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

The battery charges from the mains while the power is on, so it's ready the next time there's a power cut.
We check your motor and control box are compatible with the upgrade before the visit is booked, not on the day.
Where a door has never had photocells, any extra wiring needed is priced before we come out.
You're shown how to test the safety edge and photocells monthly, following the manufacturer's instructions for your door.

How does it work in Borehamwood?

We confirm the visit price and the cost of the battery unit, safety edge or photocells. The visit is booked, with the date confirmed in writing once an engineer is available.

Battery backup and safety upgrades in Borehamwood: questions

How much is a visit in Borehamwood?

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 Borehamwood as elsewhere we cover.

Do you cover Borehamwood?

Yes. Borehamwood is part of the area we cover in Hertfordshire, including WD6, WD7 and HA8. Get a guide price online, then we confirm a survey or visit date in writing. Dates depend on installer and engineer availability.

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

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

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

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 Borehamwood visit date is confirmed 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.
