Dave, Rosco and Junior were very efficient. With all the changes we made, Todd helped us a lot. Already is quieter. Thanks for the work. -George and Cindy W.

Very happy with the overall service provided. Great techs, very friendly and knowledgeable. -Brett K.

Thanks to John and Roscoe for doing an excellent job of installing foam and blown-in insulation in my home. From the minute they showed up at my door, I was impressed. Not only with their professionalism and work ethic, but also with the care they took when loading equipment into the house. They put down drop cloths, covered everything in plastic, and even made sure not to smash the flowers on the front walk. To top it off, before they left, they took the time to clean the messy insulation out of my garage that was there from the day before! I would definitely recommend this company - they are top notch!

Excellent service with great reps and technicians- Eric, Todd, Roscoe. They were all exceptionally polite, cooperative, courteous, and helpful. They also cleaned up well after themselves, which I really appreciated more than anything else. I also didn't feel like I had to worry about my belongings around them, they seemed so honest.

I'm totally pleased with Duersts service. The work was done promptly and neatly, it was thourough, and my new foam door for the attic opening is a work of art! I also appreciate your willingness to be involved with Focus Green Madison. I know those programs can be a hassle for contractors, but I couldn't have done these projects without the financial aid of the programs.

We are very happy with the service! The technicians were nice, approachable and professional. This is the second time we used their service and we can't be more pleased. -Juan
