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

Photocells mounted either side of the opening stop the door closing while anything is breaking the beam.
We check your motor and control box are compatible with the upgrade before the visit is booked, not on the day.
You're shown how to test the safety edge and photocells monthly, following the manufacturer's instructions for your door.
A pressure-sensitive safety edge on the bottom rail stops or reverses the door if it touches something while closing.

Rules that apply in Tonbridge

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 Tonbridge: questions

How much is a visit in Tonbridge?

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 Tonbridge as elsewhere we cover.

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

Yes. We repair roller garage doors of any make in Tonbridge and across TN9, TN11 and TN10, 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 I message you a photo of my garage in Tonbridge?

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

Do you cover Tonbridge?

Yes. Tonbridge is part of the area we cover in Kent, including TN9, TN11 and TN10. Get a guide price online, then we confirm a survey or visit date in writing. Dates depend on installer and engineer availability.

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.
