Building through the Years

Over 40 years ago, Key Builders started as a small contractor doing residential renovation work in Princeton, Illinois.

Because of company’s reputation for providing quality work and excellent customer service, Key Builders continues to increase in the size and sophistication of its projects—branching into design-build work through partnerships with architectural firms and providing  construction management services to oversee the design and construction for our clients.

Over the years, Key Builders established a track record for doing a very diverse scope of work:  

Hospital, dental, and medical facilities, distribution centers and warehouse facilities, manufacturing facilities, municipal facilities, food industries, and manufacturing  service industries, manufacturing facilities, agricultural buildings, libraries, and retirement facilities.

Key Builders has been a firm of strong values. Honesty and integrity. Quality work and open communication. Going the extra mile. Doing work right the first time. These were established as core values not just of those at the top, but of people throughout the organization. Key’s employees have consistently been high-caliber professionals who know and understand the value system that makes us a trusted business partner.

Throughout our history, we’ve remained relevant to our clients and competitive within our industry. We’ve built solid relationships with our clients with a history of quality work.

Safety is Key

At Key Builders, safety is priority number one, and the improvements in our experience modification rating are a clear measure of that commitment. We employ a safety coordinator who works with all of our clients and subcontractors to make sure risk management and risk avoidance are on everyone’s agenda during construction.


Key Builders has been working with the same surety/bonding company for more than twenty years, an accomplishment that few in our industry can claim.
