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

A pressure-sensitive safety edge on the bottom rail stops or reverses the door if it touches something while closing.
We check your motor and control box are compatible with the upgrade before the visit is booked, not on the day.
A battery backup unit lets the door run for a limited number of cycles when the mains power is off.
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 Carrickfergus: questions

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

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 Carrickfergus visit date is confirmed in writing.

Can I get a price for Carrickfergus 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.

Do you charge more for Carrickfergus than other towns in County Antrim?

No. Guide prices are the same for Carrickfergus as for anywhere else we cover in County Antrim. 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 repair roller doors you did not fit in Carrickfergus?

Yes. We repair roller garage doors of any make in Carrickfergus and across BT38, 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 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.

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.
