Manual to electric roller door conversion in Windsor: questions
What do you check at a survey in SL4?
At a survey in SL4 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.
Do you cover Windsor?
Yes. Windsor is part of the area we cover in Berkshire, including SL4, SL3 and SL1. Get a guide price online, then we confirm a survey or visit date in writing. Dates depend on installer and engineer availability.
Is the survey in Windsor 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.
Can I message you a photo of my garage in Windsor?
Yes. Photos of the opening, the inside of the garage above the door and any existing door help us give a more useful guide price for Windsor. Send them by WhatsApp or mention them in your enquiry, and we will reply in writing.
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.
