What should I know about manual to electric roller door conversion in Sunbury-on-Thames?
- Where there's no socket near the box, a qualified electrician fits a fused spur from an existing circuit, priced as a separate line.
- The free survey checks that the curtain, barrel, box and guide rails are sound and compatible before anything is quoted.
- The engineer releases the spring tension and converts or replaces the barrel so a tubular motor can drive it, with a control box on the wall.
- If your door isn't suitable for a motor, we tell you plainly and price a new electric door for comparison.

Manual to electric roller door conversion in Sunbury-on-Thames: questions
How much does manual to electric roller door conversion cost in Sunbury-on-Thames?
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 Sunbury-on-Thames as elsewhere we cover.
What do you check at a survey in TW16?
At a survey in TW16 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 an electric roller door worth it for a garage in Sunbury-on-Thames?
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 Sunbury-on-Thames garage so you can compare.
Is the survey in Sunbury-on-Thames 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.
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.
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.
