What should I know about battery backup and safety upgrades in Bishop's Stortford?

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.
After fitting, the door is tested to check it stops and reverses as it should with the new devices.

Battery backup and safety upgrades in Bishop's Stortford: questions

Can I message you a photo of my garage in Bishop's Stortford?

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 Bishop's Stortford. Send them by WhatsApp or mention them in your enquiry, and we will reply in writing.

Do you charge more for Bishop's Stortford than other towns in Hertfordshire?

No. Guide prices are the same for Bishop's Stortford as for anywhere else we cover in Hertfordshire. 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 Bishop's Stortford?

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 Bishop's Stortford as elsewhere we cover.

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.
