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

After fitting, the door is tested to check it stops and reverses as it should with the new devices.
The battery charges from the mains while the power is on, so it's ready the next time there's a power cut.
We check your motor and control box are compatible with the upgrade before the visit is booked, not on the day.
A pressure-sensitive safety edge on the bottom rail stops or reverses the door if it touches something while closing.

How does it work in Greenock?

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 Greenock

Electrics

An electric door needs a power supply near the roller box. Part P does not apply in Scotland, but electrical work must meet BS 7671 and the Scottish building standards where it forms part of building work.

Battery backup and safety upgrades in Greenock: questions

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

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 Greenock visit date is confirmed in writing.

Do you charge more for Greenock than other towns in Renfrewshire and Inverclyde?

No. Guide prices are the same for Greenock as for anywhere else we cover in Renfrewshire and Inverclyde. 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.

Can I get a price for Greenock 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.

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.

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.
