ESCANABA & MARQUETTE, Mich. (WZMQ) – Wisconsin-based company Tweet Garot Mechanical has acquired Prime Specialty Contracting, a full-service mechanical, plumbing, HVAC, and custom metal fabrication contractor in Michigan’s Upper Peninsula.
Prime Specialty Contracting has offices in Marquette and Escanaba. A press release from Tweet Garot Mechanical states that the acquisition establishes the company as the leading mechanical contractor in the U.P. and strengthens its growing statewide presence.
“I’ve known Prime’s founder Cory Bushong for many years, and I’ve watched him build something truly unique,” said Tweet Garot Chairman and CEO Christopher Howald. “In just six years, Cory and his team have built a business and a culture that stand out in this industry. We didn’t pursue Prime because of geography alone—we pursued them because of the people, the reputation, and the values they’ve established. Together, we believe we can create the dominant destination for both employees and customers in Upper Michigan.”
Prime Specialty Contracting operates through three divisions—Prime Mechanical Contracting, Prime Plumbing, Heating & Cooling, and Prime Welding & Fabrication—serving residential, commercial, and industrial clients throughout the Upper Peninsula. Both the Marquette and Escanaba facilities will maintain full operations. Bushong will remain with the company permanently, continuing to lead his team of approximately 90 employees.
“When I started Prime in 2019, the goal was always to build something our team and community could be proud of,” Bushong said. “Partnering with Tweet Garot gives us the resources, technology, and scale to take that vision even further—without changing what makes us who we are. I’m excited for what this means for our employees, our customers, and the Upper Peninsula.”
Tweet Garot President and COO Hope Voigt added, “The synergies between our organizations are natural. We share the same commitment to culture, employee development, and customer relationships. With Prime’s deep roots in the UP and Tweet Garot’s resources and technology platform, we’re positioned to offer something no one else in the region can match.”
The acquisition closed in February. Terms of the deal were not disclosed.
