What should I know about roller garage door motor replacement in Dartford?
- A compatible tubular motor is fitted inside your existing barrel and wired to the control box on the wall.
- Remotes and keypads are paired again after the motor is fitted, and each one is tested at the door.
- Safety edges and photocells are tested with the new motor, and the closing force is checked before handover.
- Motors are matched to your barrel size and curtain weight, not just to the space inside the roller box.

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.
Roller garage door motor replacement in Dartford: questions
Do you charge more for Dartford than other towns in Kent?
No. Guide prices are the same for Dartford as for anywhere else we cover in Kent. 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 cover Dartford?
Yes. Dartford is part of the area we cover in Kent, including DA1, DA2 and DA8. Get a guide price online, then we confirm a survey or visit date in writing. Dates depend on installer and engineer availability.
Can I get a price for Dartford 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 repair roller doors you did not fit in Dartford?
Yes. We repair roller garage doors of any make in Dartford and across DA1, DA2 and DA8, 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.
Can you replace the motor on any make of roller door?
We replace tubular motors on electric roller garage doors of any make, provided a compatible motor is available for the barrel size and curtain weight. Send us details of the control box and the door size and we'll confirm before booking. If a matching motor isn't available, we'll explain the options, including a new control box or a new door.
Should I replace the motor or the whole door?
Replace the motor when the rest of the door is sound: the curtain runs straight, the laths are undamaged, and the guides and barrel are in good order. If several major parts are worn, or the door has other recurring faults, a new door may be better value. The engineer will tell you plainly what they find.
