About Duerst Insulation & Concrete
Meet Lee Duerst
Owner and CEO
In 1985, I was named Director of the Weatherization Program, a Department of Energy (DOE) federal program. In this position, I was involved in third-party testing for and participated in several DOE energy studies.
It didn’t take long to see a few minor changes to the traditional insulation approach can make a world of difference. So, in 2001, I officially opened my business as Duerst Energy Consulting and Insulation.
We insulate hundreds of Wisconsin homes each year and have installed enough cellulose insulation to fill a football stadium. A high portion of our business comes from referrals, and we always stand behind our work.
I take pride in using a research-backed approach to provide the most reliable and cost effective options. Whether remodeling an existing home, adding on to a business, or building a new home or facility, better insulation means more comfort and lower bills.
Using state-of-the-art equipment and materials, we employ “green” technologies with the goal of reducing environmental impact and saving money for those we serve.
Thank you for considering us.

Services and Products
The Smart Approach
We are a top reviewed contractor in Madison, Wisconsin for a reason. Our products and approach are scientifically backed, and we’ve insulated thousands of homes in our community.
Raising and Resurfacing
Sidewalk or driveway sinking may have already cracked your sidewalk in a few spots. So long as the overall slabs are intact, we can lift, stabilize, and resurface old concrete to extend its lifespan well beyond its original life.
and so much more...
From sound reduction to ice dams, mold, comfort, and more, we can fix a lot of common building issues. That’s because many of these problems are caused by insufficient or low quality insulation. Get more out of your insulation.
State Rebates & Incentives
Many (though not all) Wisconsin insulation projects are eligible for hundreds of dollars in rebates through the state’s Department of Energy. We typically capture at least 1 rebate per week for our clients.
We are certified to implement these rebates and complete nearly all the paperwork for you. We even instantly discount the rebate from your invoice, so you’re not left waiting for the rebate check to arrive.
Know YOUR Numbers
Planning with general numbers often leads to inaccurate estimations and budgets. That’s one of the many reasons we offer free estimates. Whether you need a quick fix or are planning for work next year, work with actual numbers specific to you.
