The firm started in 1958 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.

A sheet metal shop was added to allow the company better quality and cost control over this vital aspect of mechanical projects.

In 1984, the company was purchased by The Branch Group and merged with Branch Mechanical, an established design-build mechanical contracting firm.  The resulting company, a wholly owned subsidiary of the Branch Group, an ESOP (Employee Stock Ownership Plan) company, is one of stronger financial position, stronger management, and greater technical expertise.

The company has continued to build upon the standards of quality and sound engineering skills our customers have come to expect.  In addition we feel that we have the area’s finest service department to attend to our client’s needs after construction is complete.

G.J. Hopkins, Inc. committed to providing in-house design-build capabilities to our customers in 1998.

The successful service department births the creation of two more departments (Special Projects and Controls) to better serve our clients in 1999.

In 2008, GJH proudly celebrates 50 years of providing quality services to our clients!

Our services expanded in 2011 to provide Building Information Modeling (BIM) and prefabrication of systems.
