For 45 years, ICS has stood for something simple, but powerful: loyalty, service, and integrity.
These core values—once considered old-fashioned—remain the driving force behind everything we do. They define the way we work, the relationships we build, and the legacy we continue to shape. Backed by a team of more than 100 skilled craftsmen and construction professionals, ICS has earned a reputation as one of the leading contractors in the St. Louis region and throughout the Midwest. It’s not just how we build—it’s who we are.
