In 1971, Enviromatic Corporation of America™ (Viro) began with the idea that cleaning and servicing grease exhaust systems should be done to the highest and most exacting industry standards.

Today, Enviromatic has gone further than any other company with our Roto-Steamcleaning™ and Powerwashing division and world-renowned EnVirospection® Nationwide Inspection Program, the innovative and groundbreaking, completed job picture programs... We just don't say it's clean, We prove it! The Enviroleaktest program for water leak testing grease exhaust vent systems is another example of our commitment to setting the quality standards for the industry.

Enviromatic Corporation provides the highest quality kitchen exhaust system cleaning, services, products, and consulting. We handle almost all aspects of the grease exhaust systems from assisting design, providing parts, leak testing the ductwork during construction, providing rooftop containment systems, inspecting and monitoring the cleanings outside of our service area, assisting with contracts and kitchen exhaust cleaning programs, providing kitchen exhaust training for end users and AHJs, along with our core work of cleaning and maintaining the exhaust systems. In addition to setting the industries highest quality standards, Enviromatic is also the leading innovator in the kitchen exhaust cleaning industry with many current industry standard programs either started or perfected by Enviromatic staff over the past 50 plus years.

With its strong foundation in Minneapolis, MN, Enviromatic began to expand in the 90's with the 1995 acquisition of the Blower Balancing and Repair Company and the opening of the Des Moines, St. Louis and Kansas City branches. In 2003, the acquisition of Majestic Cleaning of Rockford, IL extended Enviromatic eastward and led to additional shops being opened in:

     Houston, Texas
     Chicago, Illinois
     Dallas, Texas
     Denver, Colorado
     Atlanta, Georgia
     Columbus, Ohio
     Des Moines
     Kansas City, Missouri
     St Louis, Missouri
     Orlando, Florida
     Ft. Lauderdale, Florida
     Bloomington, Minnesota (Headquarters)
     Richmond, Virginia

As a result of the tremendous response requesting Enviromatic's quality work resulting in growth, Enviromatic Corporation of American (Viro) moved into a new state of the art national headquarters building in Bloomington MN in March 2020. We look forward to the expansion and serving more customers across the states.
