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

After fitting, the door is tested to check it stops and reverses as it should with the new devices.
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.
You're shown how to test the safety edge and photocells monthly, following the manufacturer's instructions for your door.

An electric door needs a power supply near the roller box. Electrical work must meet BS 7671, and in England some domestic electrical work is notifiable under Part P, so it is done by a registered competent person or signed off by building control.

Battery backup and safety upgrades in Prestwich: questions

Do you charge more for Prestwich than other towns in Greater Manchester?

No. Guide prices are the same for Prestwich as for anywhere else we cover in Greater Manchester. 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 Prestwich?

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

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

Yes. We repair roller garage doors of any make in Prestwich and across M25, M45 and M7, 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.

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

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 Prestwich visit date is confirmed in writing.

How often should I test the safety edge and photocells?

Test them monthly, following the manufacturer's instructions for your door. The aim is to confirm that the door stops or reverses when the safety edge meets an obstruction, and won't close while the photocell beam is broken. If either test fails, don't keep using the door until it has been checked, and request a visit.

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.
