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

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 check your motor and control box are compatible with the upgrade before the visit is booked, not on the day.
A battery backup unit lets the door run for a limited number of cycles when the mains power is off.

Rules that apply in Grays

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 Grays: questions

How much is a visit in Grays?

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 Grays as elsewhere we cover.

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

Yes. We repair roller garage doors of any make in Grays and across RM17, RM16 and RM20, 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 get a price for Grays 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 cover Grays?

Yes. Grays is part of the area we cover in Essex, including RM17, RM16 and RM20. Get a guide price online, then we confirm a survey or visit date in writing. Dates depend on installer and engineer availability.

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.

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.
