Over 40 Year's Experience

our experience is what you need

The Supermac group started over 40 years ago with two brothers – Bro & Rex doing some contracting work. When a client asked who did the job he said ‘Supermac did it’ and so Supermac was born.

This small family business started as contractors under the name of Supermac Insulation. They graduated to SMAC taking on their own projects and more recently to complete design and build contracts. To carry out the bigger contracts they not only needed more staff, but they also needed access to equipment at which point Accessmac was born.

Accesmac started out with equipment only for internal use but such was demand, it wasn’t long before it became an access hire business. Modcom was added to the company’s portfolio at a staff’s suggestion for company growth. Modcom has grown in its 20 years of operation to be a market leader in the portable building market and has an extensive hire fleet and impressive sales history.
