What should I know about battery backup and safety upgrades in Sunbury-on-Thames?

You're shown how to test the safety edge and photocells monthly, following the manufacturer's instructions for your door.
Photocells mounted either side of the opening stop the door closing while anything is breaking the beam.
A battery backup unit lets the door run for a limited number of cycles when the mains power is off.
We check your motor and control box are compatible with the upgrade before the visit is booked, not on the day.

We confirm the visit price and the cost of the battery unit, safety edge or photocells. The visit is booked, with the date confirmed in writing once an engineer is available.

Battery backup and safety upgrades in Sunbury-on-Thames: questions

How much is a visit in Sunbury-on-Thames?

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 Sunbury-on-Thames as elsewhere we cover.

Do you repair roller doors you did not fit in Sunbury-on-Thames?

Yes. We repair roller garage doors of any make in Sunbury-on-Thames and across TW16, TW17 and TW15, 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 you cover Sunbury-on-Thames?

Yes. Sunbury-on-Thames is part of the area we cover in Surrey, including TW16, TW17 and TW15. Get a guide price online, then we confirm a survey or visit date in writing. Dates depend on installer and engineer availability.

Can I message you a photo of my garage in Sunbury-on-Thames?

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 Sunbury-on-Thames. Send them by WhatsApp or mention them in your enquiry, and we will reply 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.

How many times will a battery backup open the door?

It depends on the unit, the motor and the size and weight of the door. A battery backup is designed for a limited number of cycles in a power cut, not for running the door for days. If you need the door after the battery runs down, use the manual override as the manufacturer's instructions describe.
