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

A battery backup unit lets the door run for a limited number of cycles when the mains power is off.
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.
After fitting, the door is tested to check it stops and reverses as it should with the new devices.

How does it work in Heston?

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.

Rules that apply in Heston

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 Heston: questions

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 repair roller doors you did not fit in Heston?

Yes. We repair roller garage doors of any make in Heston and across TW5, TW4 and TW3, 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 charge more for Heston than other towns in Greater London?

No. Guide prices are the same for Heston 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.

How much is a visit in Heston?

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 Heston as elsewhere we cover.

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 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.
