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

Decide whether one wide door or two single doors suits how you use the garage, especially if there is a central pier.
Ask whether pier removal needs building regulations approval before planning to turn two openings into one.
Measure the width of your opening at the top, middle and bottom, and use the narrowest figure for your guide price.
Allow extra headroom for a wide door, since larger laths make a bigger roll and need a deeper box.

Rules that apply in Blackheath

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 Blackheath: questions

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

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 Blackheath garage so you can compare.

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

No. Guide prices are the same for Blackheath 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.

How much do double and wide roller garage doors cost in Blackheath?

Our guide price for double and wide roller garage doors is from £1,395 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 Blackheath as elsewhere we cover.

Do you cover Blackheath?

Yes. Blackheath is part of the area we cover in Greater London, including SE3, SE13 and SE10. Get a guide price online, then we confirm a survey or visit date in writing. Dates depend on installer and engineer availability.

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.

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.
