About the company
S & D Mechanical Services, Inc., a Native American-owned, SBA 8(a) certified small disadvantaged business based in Grand Blanc, Michigan, operates exclusively as a prime contractor delivering HVAC system repair and replacement, plumbing infrastructure, water and sewer line upgrades, and related mechanical facility maintenance to federal defense and civilian agencies under 8(a) sole source set-asides. The firm holds active SBA 8(a) Program certification through June 13, 2027.
