At MG Plumbing & Maintenance, we are committed to delivering reliable, high-quality plumbing solutions with honesty, efficiency, and a strong focus on customer satisfaction. Originally established as AIG Industries in December 2018, the business was proudly taken over by directors Mitchell Glass and Georgia Foster in November 2022. This transition marked the beginning of an exciting new chapter, as they built upon the company’s solid foundation to develop a business known for excellence and integrity in the plumbing industry.

Professional Background

Hi, I’m Riley Johnson, the Carpentry Manager at MG Plumbing & Maintenance. I bring 16 years of hands-on experience in the carpentry industry. My journey commenced in Perth, Western Australia, in 2010 as an apprentice and I achieved my trade qualification in 2014. Following qualification, I quickly progressed into a Leading Hand position, supervising teams and coordinating works across a range of residential and commercial construction projects. During this time, I developed strong skills in project coordination, workforce management, quality control, and client liaison.

After two years as a Leading Hand, I relocated to Darwin, Northern Territory, where I expanded my experience by delivering refurbishment and new-build projects throughout Darwin and surrounding regional areas. My work also included projects within remote Indigenous communities, where I gained valuable experience managing construction activities in challenging and isolated environments while maintaining high standards of safety, quality, and stakeholder engagement.
