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

The battery charges from the mains while the power is on, so it's ready the next time there's a power cut.
You're shown how to test the safety edge and photocells monthly, following the manufacturer's instructions for your door.
After fitting, the door is tested to check it stops and reverses as it should with the new devices.
Photocells mounted either side of the opening stop the door closing while anything is breaking the beam.

Battery backup and safety upgrades in Coulsdon: questions

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

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 Coulsdon visit date is confirmed in writing.

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

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

Do you charge more for Coulsdon than other towns in Greater London?

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

Yes. We repair roller garage doors of any make in Coulsdon and across CR5, CR8 and SM7, 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.

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.

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.
