Our Story

JBH Mechanical Contracting isn’t just a business—it’s the result of hard work, dedication, and a shared vision between husband-and-wife team Zac and Cristy Hart. Founded in 2021, JBH was built from the ground up with a commitment to quality, reliability, and strong relationships. While running a business is no small feat, Zac and Cristy also juggle the demands of raising their four kids, which only strengthens their ability to adapt, problem-solve, and stay motivated in everything they do.

With over 15 years of hands-on experience as a Heavy Diesel Fitter, Zac brings extensive industry knowledge and a strong work ethic to JBH. His expertise ensures the business delivers top-tier mechanical servicing and highly skilled subcontract labour to the mining and civil sectors. A natural leader, Zac understands the importance of both technical excellence and fostering a team that takes pride in their work.

Cristy, with more than a decade of experience in administration and financial management, is the backbone of JBH’s operations. She keeps everything running smoothly behind the scenes, ensuring compliance, financial stability, and seamless day-to-day management. Her keen eye for detail and organisational skills allow the business to remain efficient, professional, and customer-focused.

Together, Zac and Cristy have built JBH Mechanical Contracting into a trusted name, known for its integrity, quality workmanship, and commitment to long-term client relationships. They take pride in providing services that not only meet but exceed industry standards, supporting some of WA’s largest mining and civil contractors.

For Zac and Cristy, JBH is more than a business—it’s a reflection of their values, hard work, and dedication to building something meaningful for their family, their team, and the industries they serve.
