About Martex Built

Choosing the builder to work with is an important financial decision. It’s potentially the largest single sum of money you’ll spend in your life. So, it’s important to get your choice right.

Some builders promise the world. But when it comes to build, you never hear from the director again. When you work with Martex Built, you will see Mario often. We restrict the number of properties we build each year. This gives you Mario’s personal attention to detail on your building project.

Mario Guglielmi Director

Mario’s number one is customer service. (Actually, it’s a joint first with the Magpies.)

“Customers want to see me, and I want to see them,” says Mario. “I stick my nose in during every stage.”

Mario caught the bug by tinkering at age seven with his bricklayer father. He then began his career as a carpenter before becoming a licenced builder. Mario established Martex in 2009. He quickly found that he’s allergic to sitting in the office. He spends his days on the road, checking the progress of projects, troubleshooting issues and managing his valued team of tradies.
