The Plumbing and Mechanical Contractors Association (PMCA) represents 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.

Today, over 250 union plumbing contractors in the region utilize PMCA's services to stay competitive and informed. 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.

PMCA traces its roots back to the first plumbing contractors association in the region, which was formed around 1980. Originally founded as the Plumbing and Piping Industry Council, we changed our name to PMCA in 1998 to more accurately represent our membership.
