What should I know about double and wide roller garage doors in Swanley?

Ask whether pier removal needs building regulations approval before planning to turn two openings into one.
Check whether the floor slopes or dips across the opening, as a wide bottom rail needs to sit evenly when closed.
Think about electric operation for any opening over 4 m, since the wide doubles in our price list are all electric.
Look along the lintel for cracks or sagging, because a wide door's box is fixed along its full length.

Rules that apply in Swanley

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.

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.

Double and wide roller garage doors in Swanley: questions

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

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 Swanley garage so you can compare.

Can you remove my old garage door in Swanley?

Yes. Every door price includes removing and disposing of an old roller or up-and-over door at your Swanley 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.

What do you check at a survey in BR8?

At a survey in BR8 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 Swanley 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 convert a double up-and-over door to a roller door?

Yes. We remove the old door and its frame, or keep the frame if it's sound, then check the lintel and reveals. The box is fitted behind the lintel and the guides to the reveals. Any extra work, such as a new lintel or building out the reveals, is priced on survey and listed separately in your written quote.

Do I need permission to turn two garage openings into one?

Removing a pier and fitting a longer lintel is structural work, and it may need Building Regulations approval. Whether planning permission is needed depends on your property, so check with your local authority, especially for listed buildings or homes in a conservation area. Our guide to planning and building regulations covers the questions to ask.
