For over 29 years, DNR Construction has been a trusted provider of weatherization and construction services in Chicago and the surrounding areas. As a true family-owned business, we take pride in our craftsmanship and commitment to excellence.

Specializing in exterior remodeling, we work on single-family homes, condominiums, and townhome complexes. Over the years, we’ve also grown to become the largest weatherization contractor in Illinois.

Our projects range from government programs and multi-unit developments to individual homeowners. While we excel in large-scale projects, we remain dedicated to serving homeowners—because that’s how our company was built.

With a comprehensive range of services, our mission remains the same: to deliver professional service and quality workmanship to every customer we serve.
