About Us

Graycor is a leading provider of construction, maintenance and facilities services throughout North America. Since its founding in 1921, Graycor has earned a strong reputation in the industry for providing innovative, collaborative solutions to its clients' unique challenges. The company also is recognized as one of the few U.S. contractors to achieve ISO 9000 registration.

The 86-year-old firm employs more than 1,500 construction specialists at its headquarters in Chicago, regional offices and project sites throughout the United States, Canada and Mexico. With revenues in excess of $600 million, Graycor ranks 123rd on Engineering News-Record's list of 400 leading U.S. contractors and 92nd on ENR's list of top 100 design-build firms; 55th among Crain's Chicago's largest private firms and 12th among Crain's Chicago's largest construction contractors. Midwest Construction also ranks Graycor as 7th among the top 50 Illinois contractors; 12th among top contractors ranked by revenue from projects completed in Illinois, Indiana and Wisconsin; and 11th among the top contractors ranked by total revenue.

To ensure its rigorous schedule, cost and quality standards, Graycor self-performs much of the trade work -- 2 million hours annually -- including concrete, carpentry, equipment installation, refractory, boiler work, steel erection, demolition and specialty blasting. Additionally, Graycor maintains intensive employee training, team-building partnering relationships with key clients, sophisticated project management information systems and stringent safety programs backed by a 15-person safety staff.

Graycor is a company of great integrity, financial strength and stability; a company dedicated to high quality and continuous improvement. Most importantly, Graycor is a company built on strong client relationships. We have built and expanded our business by growing with long-time clients as they entered new markets or identified new construction needs. Today, the majority of our business comes from ongoing relationships with clients who have come to depend on Graycor for highly responsive construction services tailored to their particular needs.
