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

Ask whether pier removal needs building regulations approval before planning to turn two openings into one.
Think about electric operation for any opening over 4 m, since the wide doubles in our price list are all electric.
Decide whether one wide door or two single doors suits how you use the garage, especially if there is a central pier.
Check whether the floor slopes or dips across the opening, as a wide bottom rail needs to sit evenly when closed.

Rules that apply in Barnet

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 Barnet: questions

Can I get a price for Barnet without anyone visiting?

Yes. The guide price tool takes four steps and gives a range for your opening and door type. It is a guide, not a quote: the written quote comes after the survey or once the visit price is agreed.

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

No. Guide prices are the same for Barnet 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.

What do you check at a survey in EN5?

At a survey in EN5 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 I need permission for a new roller garage door in Barnet?

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 a manual roller door practical on a double garage?

It can be, but only up to 4 m in our price list, and you'll be lifting a long curtain by hand each time, even with spring assistance. For a garage opened every day, or anyone who would find that hard work, an electric door is usually the better choice. Wide doubles between 4 and 5.5 m in our price list are electric.

Will a roller door give me more width than my double up-and-over door?

Possibly a little. An up-and-over door has a frame and swing-out arms at the sides, and a roller door doesn't, so converting can improve the clear width slightly. The guide rails still need some side room at each end. We measure the clear width you'd get at survey, so you know before ordering.
