About Us

A tradition of excellence...

Founded in 1981 by Chris Lavoie and Terry Vojack, our total commitment to serving our clients' needs has helped Capitol Mechanical Industries grow from a home-based business into one of the Chicago area's leading commercial plumbing and piping contractors.

Led by a hands-on management team, it is this dedication to completing projects on-time, on-budget and safely that has helped CMI become the commercial plumbing contractor of choice for many of the most respected names in the industry. Firms that bring CMI back job after job, because they know they can depend on us for top quality, professional service. We think that says a lot about us and the professionals we employ and train.

We invite you to discover the difference CMI can make on your next project. For more information, please call us at (630) 261-8070 or email us
