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

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.
You're shown how to test the safety edge and photocells monthly, following the manufacturer's instructions for your door.
We check your motor and control box are compatible with the upgrade before the visit is booked, not on the day.

How does it work in Liverpool?

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 Liverpool

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 Liverpool: questions

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

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

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 get a price for Liverpool 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 Liverpool?

Yes. We repair roller garage doors of any make in Liverpool and across L3, L2 and L1, 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.

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 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.
