The Plumbing and Mechanical Contractors Association (PMCA) represents over 250 plumbing and mechanical contractors throughout Oregon, Southwest Washington, and the northernmost counties in California. PMCA’s focus is the betterment of plumbing and mechanical contractors and the plumbing industry.

In addition to traditional residential and commercial plumbing projects, PMCA contractors work on highly complex and diverse mechanical projects such as large scale refrigeration and cooling systems, gas pipelines, medical gas systems in hospitals, and computer chip manufacturing facilities.

Originally founded in 1980 as the Plumbing and Piping Industry Council, we changed our name to PMCA in 1998 to more accurately represent our membership. Today, over 250 union plumbing contractors in the region utilize PMCA’s services to stay competitive and informed.
