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

A pressure-sensitive safety edge on the bottom rail stops or reverses the door if it touches something while closing.
The battery charges from the mains while the power is on, so it's ready the next time there's a power cut.
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.

How does it work in Watford?

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.

Rules that apply in Watford

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 Watford: questions

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.

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

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

Can I get a price for Watford 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.

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

Yes. We repair roller garage doors of any make in Watford and across WD17, WD18 and WD24, 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 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.

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.
