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

A pressure-sensitive safety edge on the bottom rail stops or reverses the door if it touches something while closing.
Where a door has never had photocells, any extra wiring needed is priced before we come out.
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.

Do you charge more for Merthyr Tydfil than other towns in Mid Glamorgan?

No. Guide prices are the same for Merthyr Tydfil as for anywhere else we cover in Mid Glamorgan. 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 Merthyr Tydfil?

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

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.
