What information to have when getting a quote for a new garage door

Whether you are wanting to replace your existing door, or perhaps you have built a new garage and want to install a new door, here are some guidelines to assist you when contacting installers to get a quote.

The more information you provide and the accuracy of the said information, the more accurate the quote will be. Also there are certain requirements that needs to be met for certain doors, and you may well get a quote on a specific type of door only to find your garage space is not suitable.

Typically installers will offer a quote on the information given, and a final quote will be issued when a site inspection was performed and measurements and limitations could be ascertained for themselves. If information given was pretty accurate deviations on the final quote will be minimal or not applicable at all.

Below you will find a breakdown of information you should gather for a quote and to get it as accurate as possible.


Firstly measure the opening of the garage, this is the actual opening for the door, not the width of the garage.

The width will be the opening size from wall to wall. The height will be from the floor to the plinth or lintel. Depending on the size of opening you may have a standard door size which is normally better priced than a custom size which have to be specially manufactured.

Pro Tip: If you are in the process of building, get the standard sizes of garage doors so there is no surprises when it comes to costing the new garage door.

Then you need to measure the nip space, this is measured from your garage wall to the inside of the opening. This nip space needs to be a minimum of 150mm to accommodate the hardware(rails and/or arms) of the doors.

Lastly you would measure the headroom, this is the space above the door opening. For sectional and rollup doors you require a minimum of 300mm. (or minimum 250mm where low headroom tracks can be installed for sectional doors).

Low headroom tracks normally comes at additional costs, in the event of construction being done ensure the minimum of 300mm headspace is adhered too.
