What should I know about safety edge and photocell repairs in Ballymena?

The engineer tests the whole circuit, because a damaged cable or control box fault can look like a failed device.
A pressure-sensitive safety edge on the bottom rail stops or reverses the door when it touches something while closing.
After a repair, the door is tested to check it stops or reverses on obstruction before it's handed back.
Replacement safety edges and photocell pairs have fitted prices, agreed before the visit is booked.

Safety edge and photocell repairs in Ballymena: questions

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

No. Guide prices are the same for Ballymena 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.

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

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 Ballymena visit date is confirmed in writing.

Can I get a price for Ballymena 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 cover Ballymena?

Yes. Ballymena is part of the area we cover in County Antrim, including BT42 and BT43. Get a guide price online, then we confirm a survey or visit date in writing. Dates depend on installer and engineer availability.

How do I test my safety edge and photocells?

Follow the manufacturer's instructions for your door. In general, the test checks that the door stops or reverses when the safety edge meets an obstruction while closing, and that the door won't close while the photocell beam is broken. Keep people and pets clear while testing, and repeat the test monthly.

Can photocells be added to a door that doesn't have them?

Often, if the control box has a connection for them. 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 photocells can be added, and the price, before booking. Our battery backup and safety upgrades page covers adding devices.
