What should I know about roller garage door replacement in Carshalton?

We take down and dispose of the old roller or up-and-over door, and that is included in every door price.
Reveals, lintel and fixing points are checked once the old door is off, and any making good is agreed with you first.
If only a lath or two is damaged on a sound door, we'll tell you that a repair may be better value.
The opening is measured again at the free survey, so the new door suits the opening rather than copying the old door's size.

Rules that apply in Carshalton

Planning

Replacing a garage door is not usually development that needs planning permission. Check first if your home is listed (listed building consent covers works that affect its character), sits in a conservation area with an Article 4 direction, or is on an estate where planning conditions or covenants control garage doors.

Structural work

Widening the opening, removing a central pier or fitting a new lintel is structural work that needs Building Regulations approval from building control before it starts.

Roller garage door replacement in Carshalton: questions

Is the survey in Carshalton 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 you remove my old garage door in Carshalton?

Yes. Every door price includes removing and disposing of an old roller or up-and-over door at your Carshalton address, along with standard fixings and making good to the reveals. If the frame or lintel needs work, we price it at the survey before you agree.

Is an electric roller door worth it for a garage in Carshalton?

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 Carshalton garage so you can compare.

What do you check at a survey in SM5?

At a survey in SM5 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 VAT included in the replacement price?

Yes. Home prices are shown including VAT. Garage doors are standard-rated at 20% and there's no reduced rate for them, so the figure in your written quote is the price you pay, unless you change the specification or further work is agreed with you in writing.

Will a new insulated door make my garage warm?

Insulated laths reduce heat loss, draughts and noise compared with single-skin laths, so the garage is more comfortable to use. The door still isn't part of the house's insulated envelope, and the walls, roof and floor matter too, so think of it as an improvement rather than turning the garage into a heated room.
