Mechanical Construction, Engineering & Service

Our Services

The mechanical construction industry has always been a very hands-on, labor-intensive operation. 


Today it is still hands-on, but in a different way.  Focusing on LEAN concepts, Integrated Project Delivery, and sustainable, efficient ideas, Hermanson Company has successfully blended the best of the old with today’s technology to provide superior service.

As a leading Mechanical Contractor in the Pacific Northwest, Hermanson offers a comprehensive suite of mechanical system design, construction and repair & maintenance services.  Within each of our specialty areas, we offer the best of both worlds – state-of-the-art technology and good old-fashioned hard work and dependability – so that we exceed our customers’ expectations.
