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

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 pressure-sensitive safety edge on the bottom rail stops or reverses the door if it touches something while closing.
After fitting, the door is tested to check it stops and reverses as it should with the new devices.

Rules that apply in Hanworth

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 Hanworth: questions

Can I get a price for Hanworth 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 Hanworth than other towns in Greater London?

No. Guide prices are the same for Hanworth as for anywhere else we cover in Greater London. 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.

Will you fix the door on the first visit?

A fault can sometimes be found and put right on the first visit, but we never promise it. If a part needs ordering, we quote for it first, make the door safe where we can, and confirm the return date in writing.

Do you cover Hanworth?

Yes. Hanworth is part of the area we cover in Greater London, including TW13, TW12 and TW2. Get a guide price online, then we confirm a survey or visit date in writing. Dates depend on installer and engineer availability.

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 a battery backup be fitted to a manual roller door?

No. A manual door has no motor or control box for a battery unit to power, because springs in the barrel balance the curtain and you lift it by hand. If you'd like powered operation, a manual-to-electric conversion may be possible when the curtain, barrel, box and guides are sound and compatible.
