American Quality


We have been in business since 2007 (started in Michigan) and have been creating crawl space encapsulation supplies since 2010. Our focus is creating & producing high quality crawl space vapor barriers, dehumidifiers and water control products that deliver results. We use our years of hands on installation experience to guide our product development.
