Duerst Insulation Technicians
Lee Duerst
Owner and CEO

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 science-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.
