G.J. Hopkins is a mechanical and electrical contracting firm based in Roanoke, Va. Since its founding in 1958, the company has grown to be one of Virginia's largest and most respected contracting firms. It started with the goal of providing mechanical contracting services from the quality perspective of sound engineering principles. Personnel with experience and technical expertise in the electrical field were added to the staff in 1963. This allowed the firm to offer both major disciplines and to provide a combined, coordinated package, which covered both fields. The company is licensed in Virginia, West Virginia, North Carolina and Tennessee.
