Rules that apply in Dorchester
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 Dorchester: questions
Do you cover Dorchester?
Yes. Dorchester is part of the area we cover in Dorset, including DT1 and DT2. Get a guide price online, then we confirm a survey or visit date in writing. Dates depend on installer and engineer availability.
Do you charge more for Dorchester than other towns in Dorset?
No. Guide prices are the same for Dorchester as for anywhere else we cover in Dorset. 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.
Can I get a price for Dorchester 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 Dorchester?
Yes. We repair roller garage doors of any make in Dorchester and across DT1 and DT2, 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.
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.
Does a new motor change how the manual override works?
It can. Different motors use different override arrangements, such as an internal crank or a winding handle. The engineer shows you how the override on your new motor works before leaving, and you should keep the handle somewhere you can find it in the dark. Our power-cut guide explains how overrides work in general.
