D N R Construction

For over 16 years DNR Construction has provided weatherization and construction services to Chicago, IL and the surrounding areas. We are a true family owned construction company; made up of four brothers, a cousin, sister and brother-in-laws. 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.

Air sealing is accomplished by sealing gaps and holes (bypasses) in the thermal boundary. The type of materials used to seal bypasses must stop the air movement. This is why rigid products must be used to seal bypasses. Types of products used in air sealing are spray foams, 1-part and 2-part, caulks and sealants, and air barrier materials such as backer rods and rigid foam board. Fiberglass insulation does not stop air flow. Although many of our competitiors believe it does!

DNR Construction provides construction services to Chicago, IL and the surrounding areas. Over the last 16 years we have built a reputation as one of the area's premier contractors. This is because we have brought together a unique group of talented and experience professionals that take pride in their work. Our work has an emphasis on exterior remodeling and we believe that specializing on core services, rather than taking the "jack of all trades" approach, helps us accomplish our goals for our customers.

There are many reasons for wanting to make your home more energy efficient. Many of our customers simply want lower energy costs and to be more comfortable in their home. Others may want to lower their carbon footprint, help the environment or reduce our dependency on foreign countries. For these reasons and more, DNR Construction weatherizes thousands of homes annually. We differ from the common insulation company because our process takes the entire home into account. By dealing with only one aspect of a home may not correct the issue.
