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

Measure the width of your opening at the top, middle and bottom, and use the narrowest figure for your guide price.
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.
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 Harpenden

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 Harpenden: questions

Can I message you a photo of my garage in Harpenden?

Yes. Photos of the opening, the inside of the garage above the door and any existing door help us give a more useful guide price for Harpenden. Send them by WhatsApp or mention them in your enquiry, and we will reply in writing.

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

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 Harpenden as elsewhere we cover.

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

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 Harpenden garage so you can compare.

What do you check at a survey in AL5?

At a survey in AL5 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.

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.

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.
