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

You're shown how to test the safety edge and photocells monthly, following the manufacturer's instructions for your door.
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.
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 Chepstow?

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 Chepstow: questions

Can I get a price for Chepstow 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 I message you a photo of my garage in Chepstow?

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

Do you charge more for Chepstow than other towns in Gwent?

No. Guide prices are the same for Chepstow as for anywhere else we cover in Gwent. 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.

Do you cover Chepstow?

Yes. Chepstow is part of the area we cover in Gwent, including NP16. Get a guide price online, then we confirm a survey or visit date in writing. Dates depend on installer and engineer availability.

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.

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.
