What should I know about made-to-measure roller garage doors in Welwyn Garden City?

Read the sizes, fitting position and box position in your written quote carefully, because that's what the door will be made to.
Note any piers, downpipes or meter boxes outside the opening that could affect a face-fixed door or box.
Check the height at both sides and in the middle, since an uneven floor can make one side of the opening taller than the other.
Check the clear wall either side of the opening, since the guide rails typically need around 75 to 100 mm each side.

Rules that apply in Welwyn Garden City

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.

Made-to-measure roller garage doors in Welwyn Garden City: questions

What do you check at a survey in AL8?

At a survey in AL8 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.

How much do made-to-measure roller garage doors cost in Welwyn Garden City?

Our guide price for made-to-measure roller garage doors is from £1,495 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 Welwyn Garden City as elsewhere we cover.

How long does it take to fit a roller garage door in Welwyn Garden City?

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.

Do you cover Welwyn Garden City?

Why might my measurements differ from the surveyor's?

Openings are rarely perfectly square, so width and height often vary by a few millimetres from one point to another. The surveyor measures at several points, checks the floor level and works to the figures the door must fit. Small differences from your own measurements are normal, and the written quote is based on the survey.

What if my opening is narrower than a typical garage door?

Narrow openings are fine, because the door is built to your width. Side room is the main thing to check, since each guide rail needs some clear wall beside the opening. If the opening is narrow and you'd like as much clear width as possible, we'll explain how each fitting position affects the space you'll have for the car.
