Guin Service began in 1958 as a group of specialized mechanics to compliment Guin Company’s mechanical contracting company. W.C. (Bill) Guin knew that to have a successful contracting company he must have top mechanics to start-up and service contract jobs. Over the years the contracting company grew to one of Alabama's largest by doing quality work and providing exceptional customer service. In the mid 90’s as the top management of the company began to retire, the decision was made to discontinue the mechanical contracting division. Because of the loyalty of the employees of the service department and their many customers, the service company became an independent operation.

Through the leadership of Ricky Lockheart, Manager; Keith Rotenberry, Assistant Manager; and Peggy Rice, Office Manager, Guin Service Company has continued to thrive. Associates Marvin Watson, Richard McDonald, Dewayne Todd, Tommy Thrasher, Jay Guin, Gary Rice, and their teams, have continued the legacy of friendly customer service. Each associate is highly qualified with 20+ years’ experience. As everyone knows, to have a successful business you must have the best people and GUIN SERVICE, INC. has the best. GUIN SERVICE, INC. has been in business since 1958 and strives everyday to make sure that customer satisfaction is guaranteed.

W.C. (Bill) Guin, is retired but remains available for backup to the team. He is very proud of the continued success GUIN SERVICE INC. and has made plans for the operation to continue for many years to come.
