About Us

Founded in Frankenmuth in 1988, Winninger Fire Protection has grown

In 1988, as a journeyman sprinkler fitter and plumber, Hal Wininger applied for his Michigan Mechanical Contractor’s License to start Wininger Fire Protection, Inc. From his barn in Frankenmuth, MI he came armed with a Construction Management degree from Ferris State University and 16 years of skilled trade knowledge. He slowly grew the company but quickly gained a reputation for dependable, efficient, quality installations of fire protection systems. Early projects included the world famous Bronner’s Christmas Wonderland and Bavarian Inn in Frankenmuth and the University of Toledo Museum of Art. The sphere of construction now stretches from military barracks and industrial buildings to churches and nursing homes.

Proud of his Frankenmuth (Michigan’s Little Bavaria) background, Hal decided to change the spelling of his company’s name to Winninger Fire Protection, to reflect the town and his German roots. For more than 30 years, the company has remained a family owned and operated enterprise. Hal continues to oversee much of the design and installation. His son Wes, lured from his pharmacist career, has joined the company by directing estimating, purchasing and project management.
