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

Photocells mounted either side of the opening stop the door closing while anything is breaking the beam.
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.
After fitting, the door is tested to check it stops and reverses as it should with the new devices.

How does it work in Daventry?

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 Daventry

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 Daventry: questions

Do you charge more for Daventry than other towns in Northamptonshire?

No. Guide prices are the same for Daventry as for anywhere else we cover in Northamptonshire. 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.

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

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

How much is a visit in Daventry?

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 Daventry as elsewhere we cover.

Do you cover Daventry?

Yes. Daventry is part of the area we cover in Northamptonshire, including NN11. Get a guide price online, then we confirm a survey or visit date in writing. Dates depend on installer and engineer availability.

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.

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.
