What should I know about battery backup and safety upgrades in Bangor (County Down)?

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.
A pressure-sensitive safety edge on the bottom rail stops or reverses the door if it touches something while closing.
Photocells mounted either side of the opening stop the door closing while anything is breaking the beam.

Battery backup and safety upgrades in Bangor (County Down): questions

Do you repair roller doors you did not fit in Bangor (County Down)?

Yes. We repair roller garage doors of any make in Bangor (County Down) and across BT20 and BT19, 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 get a price for Bangor (County Down) 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.

What should I do while I wait for a visit in Bangor (County Down)?

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 Bangor (County Down) visit date is confirmed in writing.

Do you cover Bangor (County Down)?

Yes. Bangor (County Down) is part of the area we cover in County Down, including BT20 and BT19. Get a guide price online, then we confirm a survey or visit date in writing. Dates depend on installer and engineer availability.

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.

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.
