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

Where an old electric door already has power near the box, the supply is checked before it is reused for the new door.
Reveals, lintel and fixing points are checked once the old door is off, and any making good is agreed with you first.
If only a lath or two is damaged on a sound door, we'll tell you that a repair may be better value.
Security-rated models are available, and we show you the manufacturer's certificate for the exact door being quoted.

How does it work in Harrow?

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 Harrow

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 Harrow: questions

What do you check at a survey in HA1?

At a survey in HA1 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.

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

No. Guide prices are the same for Harrow 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.

Can you remove my old garage door in Harrow?

Yes. Every door price includes removing and disposing of an old roller or up-and-over door at your Harrow address, along with standard fixings and making good to the reveals. If the frame or lintel needs work, we price it at the survey before you agree.

Do I need permission for a new roller garage door in Harrow?

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.

Will a new insulated door make my garage warm?

Insulated laths reduce heat loss, draughts and noise compared with single-skin laths, so the garage is more comfortable to use. The door still isn't part of the house's insulated envelope, and the walls, roof and floor matter too, so think of it as an improvement rather than turning the garage into a heated room.

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.
