Harder Mechanical Contractors (HMC) is a privately owned construction company founded in 1934. We started in commercial plumbing and evolved into a major mechanical contractor when asked to help build the first hydroelectric dams throughout the Pacific Northwest. Our experience and industry diversification grew as new industries came to the region, enticed by abundant water and surplus electrical power. Our work and consistent performance quickly recognized Harder Mechanical Contractors, Inc. as a leading contractor for industries like power generation, pulp and paper, oil, gas, chemical, steel, aluminum, aerospace, food and beverage, industrial manufacturing, and now microelectronics, life sciences, health care, higher education, solar manufacturing, data centers, and renewable energies.
