What should I know about battery backup and safety upgrades in Chester-le-Street?
- You're shown how to test the safety edge and photocells monthly, following the manufacturer's instructions for your door.
- We check your motor and control box are compatible with the upgrade before the visit is booked, not on the day.
- The battery charges from the mains while the power is on, so it's ready the next time there's a power cut.
- After fitting, the door is tested to check it stops and reverses as it should with the new devices.
How does it work in Chester-le-Street?

Rules that apply in Chester-le-Street
Powered door safety
Every powered door we fit is commissioned with force testing to BS EN 12453 and handed over with a Declaration of Conformity and UKCA or CE marking, as the Supply of Machinery (Safety) Regulations 2008 require.
Electrics
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 Chester-le-Street: questions
Do you charge more for Chester-le-Street than other towns in County Durham?
No. Guide prices are the same for Chester-le-Street as for anywhere else we cover in County Durham. 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.
What should I do while I wait for a visit in Chester-le-Street?
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 Chester-le-Street visit date is confirmed in writing.
Will you fix the door on the first visit?
A fault can sometimes be found and put right on the first visit, but we never promise it. If a part needs ordering, we quote for it first, make the door safe where we can, and confirm the return date in writing.
Can I get a price for Chester-le-Street 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.
Can a battery backup be fitted to a manual roller door?
No. A manual door has no motor or control box for a battery unit to power, because springs in the barrel balance the curtain and you lift it by hand. If you'd like powered operation, a manual-to-electric conversion may be possible when the curtain, barrel, box and guides are sound and compatible.
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.
