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

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.
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.

How does it work in Dronfield?

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.

Battery backup and safety upgrades in Dronfield: questions

Do you cover Dronfield?

Yes. Dronfield is part of the area we cover in Derbyshire, including S18, S17 and S8. Get a guide price online, then we confirm a survey or visit date in writing. Dates depend on installer and engineer availability.

Do you charge more for Dronfield than other towns in Derbyshire?

No. Guide prices are the same for Dronfield as for anywhere else we cover in Derbyshire. 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 Dronfield?

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

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

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 Dronfield visit date is confirmed in writing.

How often should I test the safety edge and photocells?

Test them monthly, following the manufacturer's instructions for your door. The aim is to confirm that the door stops or reverses when the safety edge meets an obstruction, and won't close while the photocell beam is broken. If either test fails, don't keep using the door until it has been checked, and request a visit.

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.
