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

You're shown how to test the safety edge and photocells monthly, following the manufacturer's instructions for your door.
A battery backup unit lets the door run for a limited number of cycles when the mains power is off.
Photocells mounted either side of the opening stop the door closing while anything is breaking the beam.
Where a door has never had photocells, any extra wiring needed is priced before we come out.

Battery backup and safety upgrades in Sidcup: questions

Do you cover Sidcup?

Yes. Sidcup is part of the area we cover in Greater London, including DA14, DA15 and DA5. Get a guide price online, then we confirm a survey or visit date in writing. Dates depend on installer and engineer availability.

How much is a visit in Sidcup?

Prices for battery backup and safety upgrades start from £99 inc VAT, and the price is agreed before anyone comes out. Any parts not covered by that price are quoted before they are fitted, so you can decide on the spot. The guide prices are the same in Sidcup as elsewhere we cover.

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

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 Sidcup visit date is confirmed in writing.

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

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

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 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.
