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

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.
Look along the lintel for cracks or sagging, because a wide door's box is fixed along its full length.
Decide whether one wide door or two single doors suits how you use the garage, especially if there is a central pier.

Rules that apply in Carshalton

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 Carshalton: questions

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.

Do you charge more for Carshalton than other towns in Greater London?

No. Guide prices are the same for Carshalton as for anywhere else we cover in Greater London. The written quote reflects your opening and the door you choose, not your postcode, apart from islands and remote areas where any travel cost is shown in advance.

Do I need permission for a new roller garage door in Carshalton?

Replacing a garage door is not usually development that needs planning permission in England, and widening the opening needs building control approval. If you live in a listed building, a conservation area or on an estate with covenants or planning conditions, check before ordering.

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 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.
