43 years ago, ICS was founded on a few old fashioned values, sometimes rare in today's business world. Loyalty. Customer Service. Integrity. The kind of values that set ICS apart in the industry, and define our special brand of partnership. These are the values that are embraced by the ICS team – more than 100 skilled craftsman and building industry professionals. Without question, these are the values that have helped ICS become one of the premier contractors in the St. Louis metropolitan area, and the Midwest.
