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

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.
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.

Rules that apply in Finchley

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 Finchley: questions

Do you cover Finchley?

Yes. Finchley is part of the area we cover in Greater London, including N3, N12 and N2. Get a guide price online, then we confirm a survey or visit date in writing. Dates depend on installer and engineer availability.

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

No. Guide prices are the same for Finchley 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.

Is the survey in Finchley 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.

How long does it take to fit a roller garage door in Finchley?

Most single domestic roller doors are fitted in a day once the door has been made, including removing the old door. Wider doors, conversions that need building work and jobs where power has to be run can take longer; the quote says what to expect.

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.

What if my garage opening is wider than 5.5 m?

We price it on survey. Openings over 5.5 m fall outside our standard price bands, because the door, the lintel and the fixing points need to be checked and specified individually. You can still use the online tool to tell us about the opening, and we'll arrange a free survey and give you a written quote.
