Manual to electric roller door conversion in Dereham: questions
Do you cover Dereham?
Yes. Dereham is part of the area we cover in Norfolk, including NR19. Get a guide price online, then we confirm a survey or visit date in writing. Dates depend on installer and engineer availability.
What do you check at a survey in NR19?
At a survey in NR19 we measure the width and height of the opening, the headroom above it for the roller box, the side room for the guide rails and the floor level. We also look at the lintel and where power can come from for an electric door.
Is the survey in Dereham really free?
Yes. For a new door, a replacement or a conversion, the survey is free and there is no obligation to go ahead. We measure the opening, check the lintel, headroom, side room and power, and send a written quote afterwards.
How much does manual to electric roller door conversion cost in Dereham?
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 Dereham as elsewhere we cover.
Do I need an electrician for a conversion?
An electric door needs a power supply near the box, usually a fused spur or a socket. If you already have one in a suitable place, it can normally be used. If not, a qualified electrician fits a new fused spur, priced separately in your quote. In England and Wales some domestic electrical work is notifiable under Part P.
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.
