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

A battery backup unit lets the door run for a limited number of cycles when the mains power is off.
The battery charges from the mains while the power is on, so it's ready the next time there's a power cut.
Photocells mounted either side of the opening stop the door closing while anything is breaking the beam.
Where a door has never had photocells, any extra wiring needed is priced before we come out.

How does it work in Grantham?

We confirm the visit price and the cost of the battery unit, safety edge or photocells. The visit is booked, with the date confirmed in writing once an engineer is available.

Rules that apply in Grantham

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 Grantham: questions

Do you charge more for Grantham than other towns in Lincolnshire?

No. Guide prices are the same for Grantham as for anywhere else we cover in Lincolnshire. 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 message you a photo of my garage in Grantham?

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

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

Yes. We repair roller garage doors of any make in Grantham and across NG31 and NG32, 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.

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.

How many times will a battery backup open the door?

It depends on the unit, the motor and the size and weight of the door. A battery backup is designed for a limited number of cycles in a power cut, not for running the door for days. If you need the door after the battery runs down, use the manual override as the manufacturer's instructions describe.
