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

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.
A pressure-sensitive safety edge on the bottom rail stops or reverses the door if it touches something while closing.
You're shown how to test the safety edge and photocells monthly, following the manufacturer's instructions for your door.

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 Chalk Farm

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 Chalk Farm: questions

Can I message you a photo of my garage in Chalk Farm?

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

How much is a visit in Chalk Farm?

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 Chalk Farm as elsewhere we cover.

Can I get a price for Chalk Farm 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 Chalk Farm?

Yes. We repair roller garage doors of any make in Chalk Farm and across NW3, NW5 and NW1, 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.

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.
