Rules that apply in Trowbridge
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.
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.
Manual to electric roller door conversion in Trowbridge: questions
Is an electric roller door worth it for a garage in Trowbridge?
That depends on how often you use the garage. An electric door opens from the car with a remote and has safety devices fitted, while a manual door costs less and suits occasional use. We price both for your Trowbridge garage so you can compare.
Can I get a price for Trowbridge 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.
How much does manual to electric roller door conversion cost in Trowbridge?
Our guide price for manual to electric roller door conversion is from £495 inc VAT. The figure for your garage depends on the opening size, the door specification and any extras, and is confirmed in a written quote after a free survey. The guide prices are the same in Trowbridge as elsewhere we cover.
Do you charge more for Trowbridge than other towns in Wiltshire?
No. Guide prices are the same for Trowbridge as for anywhere else we cover in Wiltshire. 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.
How do I know if my manual roller door can be motorised?
The only reliable way is a survey. We check that the curtain runs smoothly, the laths are undamaged, and the barrel, box and guide rails are sound and compatible with a tubular motor. If they are, we quote for the conversion; if not, we explain why and price a new electric door so you can compare the two.
Will I still be able to open the door by hand?
Not in the way you do now, because the motor holds the curtain in place. Most electric roller doors have a manual override, usually an internal crank or winding handle, for use in a power cut. A battery backup unit can also be added so the door runs for a limited number of cycles when the power is off.
