About DNR Construction

Small business owner Rick Helwig is helping residents of metropolitan Chicago make their buildings more energy-efficient and weather-proof.

For over 16 years DNR Construction has provided weatherization and construction services to Chicago and the surrounding areas. We are a true family owned construction company. We specialize in the exterior remodeling of single family, condominium, and townhome complexes. In addition, we have become the largest weatherization contractor in the state of Illinois.

Our projects include governmental programs, multi-unit complexes, and the individual homeowner. Although we specialize is larger scale jobs, we continue to service the individual homeowner because that is how we grew our company.

We provide a wide array of services, but we have one goal in mind—to provide professional service and quality workmanship for our customers.
