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

We check your motor and control box are compatible with the upgrade before the visit is booked, not on the day.
You're shown how to test the safety edge and photocells monthly, following the manufacturer's instructions for your door.
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.

Battery backup and safety upgrades in Dagenham: questions

Can I get a price for Dagenham 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.

Do you cover Dagenham?

Yes. Dagenham is part of the area we cover in Greater London, including RM10, RM9 and RM8. 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 Dagenham?

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 Dagenham as elsewhere we cover.

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

Yes. We repair roller garage doors of any make in Dagenham and across RM10, RM9 and RM8, 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.

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.

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.
