Hermanson Company was founded by Jerry Hermanson in 1979 as a sheet metal contractor engaged in the fabrication and installation of commercial and industrial heating and air conditioning systems. From the very beginning, we worked with the most respected General Contractors and owners in the region and were an integral part of constructing some of the area’s iconic buildings – from downtown Seattle’s Columbia Tower to the Boeing Field Museum of Flight to the Washington State Convention Center.
Today’s Hermanson Company is a full-service mechanical contractor offering sheet metal, piping and plumbing design and construction services to meet a variety of mechanical system needs. Our main office and 32,000 s.f. fabrication shop are located in Kent, Washington. From this base we have successfully served customers throughout the Puget Sound region, in Eastern Washington, Alaska, Oregon, and California.
Hermanson Company is a union contractor, assuring that our workforce is well-trained and dedicated to excellence. Our non-bargaining staff is experienced, creative and committed. Together, we form a community of professionals with a common goal – to deliver the absolute best in mechanical construction, exceeding our client’s expectations.
