What should I know about roller garage door replacement in Harpenden?

If only a lath or two is damaged on a sound door, we'll tell you that a repair may be better value.
Where an old electric door already has power near the box, the supply is checked before it is reused for the new door.
We take down and dispose of the old roller or up-and-over door, and that is included in every door price.
Moving from single-skin to insulated laths reduces heat loss, draughts and noise in a garage you use every day.

How does it work in Harpenden?

We measure the opening, check how the old door is fixed, and look at headroom, side room, the lintel and power. Your written quote lists the new door, extras, removal and disposal of the old one, and anything priced on survey.

Rules that apply in Harpenden

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.

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.

Roller garage door replacement in Harpenden: questions

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.

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

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 I need permission for a new roller garage door in Harpenden?

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.

Can I get a price for Harpenden 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.

Can you replace a roller door made by a different company?

Yes. We replace roller garage doors of any make, and up-and-over doors too. The old door is removed and disposed of as part of the price, so it doesn't matter who made or fitted it. What matters is the opening itself, which we measure afresh at the free survey before quoting.

Can I keep my old roller box and just change the curtain?

Our replacement prices are for a complete new door, because a new curtain needs a barrel, box, guides and controls that are matched to it. If only a few laths are damaged on an otherwise sound door, a lath repair may be the better option, and we'll say so if that's the case.
