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

After fitting, the door is tested to check it stops and reverses as it should with the new devices.
Where a door has never had photocells, any extra wiring needed is priced before we come out.
You're shown how to test the safety edge and photocells monthly, following the manufacturer's instructions for your door.
A pressure-sensitive safety edge on the bottom rail stops or reverses the door if it touches something while closing.

Battery backup and safety upgrades in Coleraine: questions

Do you repair roller doors you did not fit in Coleraine?

Yes. We repair roller garage doors of any make in Coleraine and across BT52, where parts are available. If a part is no longer made, we tell you what will fit instead, or price a replacement door if that is the better option.

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

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

Do you cover Coleraine?

Yes. Coleraine is part of the area we cover in County Londonderry, including BT52. Get a guide price online, then we confirm a survey or visit date in writing. Dates depend on installer and engineer availability.

Will you fix the door on the first visit?

A fault can sometimes be found and put right on the first visit, but we never promise it. If a part needs ordering, we quote for it first, make the door safe where we can, and confirm the return date 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.

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.
