Celebrating 90 years of excellence and innovation, Harder Mechanical Contractors traces its roots back to 1934 when James Michel Harder embarked on a journey to fulfill the American Dream amidst the Great Depression, founding J.M. Harder Plumbing. Over the decades, five generations of the Harder family have transformed this local startup into a national powerhouse.
