Illinois Offices

Founded in Illinois in 1937, our firm began as a humble masonry company. Since then, CORE Illinois has grown into a thriving construction leader in the area, and across the country. Our local team, with roots deep in the community, sets the standard for excellence with award-winning projects in the K-12 and Higher Education markets, as well as the public safety space. We continue to invest in our “home” state through our dedicated service to our communities.
