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

Photocells mounted either side of the opening stop the door closing while anything is breaking the beam.
After fitting, the door is tested to check it stops and reverses as it should with the new devices.
Where a door has never had photocells, any extra wiring needed is priced before we come out.
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 Greenwich?

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.

Covering Greenwich and nearby

Greenwich is within the area we cover in Greater London. Homes in SE10, SE8 and SE14 get the same survey, quote and fitting process as everywhere else we work. Greenwich is about 6 miles from Westminster.

Rules that apply in Greenwich

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 Greenwich: questions

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

Yes. We repair roller garage doors of any make in Greenwich and across SE10, SE8 and SE14, 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 Greenwich?

Yes. Greenwich is part of the area we cover in Greater London, including SE10, SE8 and SE14. Get a guide price online, then we confirm a survey or visit date in writing. Dates depend on installer and engineer availability.

What should I do while I wait for a visit in Greenwich?

If the door is stuck part-open, keep people, pets and cars clear of it and switch off the power at the isolator if it is safe to reach. Do not force the curtain or open the roller box. Your Greenwich visit date is confirmed in writing.

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

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

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.
