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

Where a door has never had photocells, any extra wiring needed is priced before we come out.
Photocells mounted either side of the opening stop the door closing while anything is breaking the beam.
A battery backup unit lets the door run for a limited number of cycles when the mains power is off.
You're shown how to test the safety edge and photocells monthly, following the manufacturer's instructions for your door.

Rules that apply in Chatham

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 Chatham: questions

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

Yes. We repair roller garage doors of any make in Chatham and across ME4, ME7 and ME1, 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.

Do you cover Chatham?

Yes. Chatham is part of the area we cover in Kent, including ME4, ME7 and ME1. Get a guide price online, then we confirm a survey or visit date in writing. Dates depend on installer and engineer availability.

Can I get a price for Chatham 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 charge more for Chatham than other towns in Kent?

No. Guide prices are the same for Chatham as for anywhere else we cover in Kent. The written quote reflects your opening and the door you choose, not your postcode, apart from islands and remote areas where any travel cost is shown in advance.

How often should I test the safety edge and photocells?

Test them monthly, following the manufacturer's instructions for your door. The aim is to confirm that the door stops or reverses when the safety edge meets an obstruction, and won't close while the photocell beam is broken. If either test fails, don't keep using the door until it has been checked, and request a visit.

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.
