Why does a roller garage door need to be made to measure?

A roller garage door needs to be made to measure because the curtain, guides and box have to suit the width, height, headroom and side room of your particular opening.

Garage openings vary more than you might expect. Two houses on the same street can have openings a few centimetres apart in width, with different lintel heights and different amounts of space above the opening. A roller door that's even slightly the wrong size can leave gaps at the sides, rub in the guides or not close evenly on the floor.

Building the door to measured sizes avoids that. It also opens up choices a stock door can't offer, such as a smaller box for tight headroom or a different fitting position when the reveals aren't suitable. If your garage has very little space above the opening, our page on low-headroom roller garage doors explains the options.

How do I measure my garage opening for a guide price?

For a guide price you need four measurements: the width, the height, the headroom above the opening, and the side room either side of it.

1. Width: measure between the reveals at the top, middle and bottom, and use the smallest figure.
2. Height: measure from the floor to the underside of the lintel at both sides and in the middle.
3. Headroom: measure from the underside of the lintel up to the ceiling or the lowest obstruction inside the garage.
4. Side room: measure the clear wall either side of the opening inside; guides typically need around 75 to 100 mm.

Your figures only need to be close for a guide price. We measure again at the free survey, and the door is built to the survey measurements, not yours. Our step-by-step guide on how to measure for a roller garage door covers the awkward cases.

How much does a made-to-measure roller door cost?

Made-to-measure roller doors are priced by width band, starting at £1,495–£2,295 inc VAT for an insulated electric door on an opening up to 2.4 m wide.

An insulated electric door for a double opening of 3.0 to 4.0 m costs £2,195–£3,295 inc VAT. Manual, single-skin electric, steel and security-rated doors each have their own bands, which you can compare on our prices page. Within a band, the door is still built to your exact sizes.

Every price includes supply, fitting and the removal and disposal of your old roller or up-and-over door, with VAT at 20%. Some things fall outside the bands and are priced on survey:

• openings wider than 5.5 m
• steel doors wider than 4 m
• structural work, such as a new lintel or building out the reveals
• colours that aren't in the manufacturer's range

What can be adjusted to suit an unusual garage opening?

The fitting position, the position of the box and the size of the lath can all be adjusted to suit an opening that isn't straightforward.

Most doors are fitted behind the opening, with the guides on the inside face of the wall. Where that doesn't work, the door can be fitted between the reveals or face-fixed on the front of the wall. The box can go behind the lintel, which is the usual choice, under the lintel, which reduces the clear opening height, or in front of the wall when there's no room inside.

The lath matters too. Larger laths add rigidity on wider doors but need a bigger box, so the right choice balances width against headroom. Where the reveals are uneven or there isn't enough wall for the guides, they can sometimes be built out. That work is priced on survey and listed separately, so you can see what it adds.

What happens between the survey and fitting of a made-to-measure door?

Your survey measurements become the order: once you accept the written quote, the door is made to those sizes and your fitting date is confirmed in writing.

At the free survey we take the measurements the door will be built to, and check the lintel, floor level, access and, for an electric door, the power supply. The written quote then sets out the door, its sizes, the fitting and box positions, the finish and any extras. Nothing is ordered until you've agreed that quote, so check it carefully. The fitting date depends on installer availability.

On fitting day, the old door is removed and taken away, and the new door is installed in the position set out in your quote. An electric door is commissioned, with its limits set and safety devices tested, and you're shown how to use the manual override.
