Don Conklen Construction Inc. began earning its solid reputation for craftsmanship and quality construction more than 50 years ago. Since then, our clients have trusted us to build countless residential, commercial and agricultrual buildings throughout the Sauk Valley region. Our reputation for completing tough projects with demanding time and budget constraints stems in part from the tools we use. We support our crews in the field with modern, innovative equipment. We supply our office personnel with the latest computer systems for accounting, estimating, job cost and billing. This consistent policy of reinvestment enables us to work harder, faster and smarter and serve our clients better.
