Duerst Insulation Technicians

Duerst did a great job from the beginning. They returned my call fro an estimate immediately (anyone calling contractors knows that that is not the norm). Todd set up a time to stop over, came promptly and it was obvious that he knew what he was talking about. He brought up things that I'd never even thought about and listened to what I needed. The Duerst estimate was a little higher than the other one I'd gotten but the detail on the estimate was excellent. The workers came to do the work within 2 weeks as scheduled and did an awesome job. They were courteous and let me know how they were going to do the work. They blew insulation in the attic and found places that needed more and added the extra. Then they donned their spray foam outfits and filled all the sills in the basement. They were very efficient and had the job done in one day. Afterwards, they pulled out their shop-vac and cleaned up after themselves. My house was almost cleaner when they left. My house is now warmer and more energy efficient than ever. I expect to have lower energy bills next winter. Thanks for the excellent service!

Looking for recommendations on insulators in the area, I contacted a sales rep for the spray insulation I had been looking at. Lee was recommended by the rep and came right out for an estimate. He was very knowledgeable and walked me through the several different types of products available and made sure we had the right product for our job. His installers Chris and Bruce were very professional and did a top notch job. Cleanliness and thorough workmanship start to finish. The job site was very neat when they finished and they made sure I was satisfied with the job before they finished. Lee came back out afterwards to double check the job and again made sure I was happy and everything was done to our satisfaction. I would definitely use them for any work again and would highly recommend them to anyone who asks. Their pricing was very reasonable and fair especially for the amount of work we had to do. They didn't come in low to get the job and run me up the ladder. His workmanship was great start to finish.

If I could give 10 stars.. I would. I don't even know where to begin about this company and their team members. It appears my builder in Waunakee (P****** Builders) did a poor job when laying my front porch. When I reached out to the builder to talk with them they wouldn't give me the time of day becaue the warranty is one year. I called Duerst. They were at my house the next day to look at the porch and provide me a bid. When they started the work the following week, they realized the prior workmanship was poor which required them to do more work to make it right. The owner himself, Lee Duerst, came out not once, but twice. to talk with me and follow up on the progress and completion of the porch. I would ABSOLUTELY recommend Duerst Insulation and Concrete. Diane, Trevor, Lee, the guys that came out, all wonderful!! Thank you so much

We have an older cedar shake home with plaster walls, so finding a contractor who was willing to take on our insulation job was impossible, until I called Duerst. Trevor came out the same day I called and about a week later our house was insulated and there is a noticeable difference in comfort level. There was amazing communication throughout the whole process, and minimal disruption/mess in our home. The crew took extra time and care to make sure the cedar shake wasn’t damaged. It was so nice to minimize the inside plaster repair. This was the truly the best money we’ve spent on a home project. Our home is cozy and comfortable now and we can’t wait to see the difference in our energy bills!

Durest Inusulation installed spray foam insulation my in the sill boxes of my basement. They did an excellent job at all stages of the project from initial inspection and quote, scheduling, and doing the job. Both Trevor and Nick were great, very professional and kept me updated throughout the day. When they ran into unexpected issues (our house is 30 years old) they showed me pictures of the issue and proposed a solution. For one issue they couldn't handle, they are sending me names of contractors. There is a noticeable difference in the basement temperature and the price was very reasonable. I would highly recommend Duerst Insulation!
