An Organization of Union – Affiliated Contractors

Our Mission

The Great Southwestern Illinois Association of Plumbing-Heating-Cooling and Mechanical Contractors is dedicated to the promotion, advancement, education and training of the industry for the protection of our environment and the health, safety and comfort of our community.

The Association is an organization of union-affiliated contractors, primarily located in the southwestern Illinois counties of St. Clair, Madison, Bond, Clinton, Monroe, Randolph and Washington. Contractor members of the Association employ members of the United Association of Journeymen and Apprentices of the Plumbing and Pipe Fitting Industry of the United States and Canada.

Our members install and service hot water systems, steam boilers, air conditioning units, as well as plumbing and drains. We and our fellow contractors provide the safest piping systems for water purification, hospitals, sewage treatment, power plants, steel mills and many other public and private buildings.
