Get matched with top insulation pros in Fond Du Lac, WI

"We have been in a 2 year long build with many facets. I reached out to Dason at the very beginning about the project and his professional insight was spot on. I had very specific engineering requirements for our build to achieve a very high performance, Thermal comfort gave us what I required. I had a previous Spray foam contractor from a prior build and received 3 additional bids for this 2020 project. I choose Thermal comfort from the 4 companies for several reasons and I am very pleased that I did. Closed cell IMO is the only way to go, that said the install is critical and the site crew was fantastic. George, was the lead and listened to my install concerns and did an excellent job. Rich and Walt were also on hand and also did great. They accommodated us the best possible in the timing of our project. They were thorough, conscientious and and their site prep and clean up was excellent. We have future projects and they will be our insulation contractor from now on."

"I still have vacuum lines in my carpet from where they cleaned up after themselves! In addition to responsive customer service, competitive prices, and a polite, clean work crew; CM Advance Insullation was easy to work with and did a fantastic job. I was invited to inspect the work and could easily see that the job had been done well."

"They showed up on time and went right to work. They did a very good job with the insulating and cleaned everything up. Thanks"

"They had a great group of people to work with, The crew was there at the appointment time. Nick and his team worked together well to get the job done, including adding insulation to the attic, adding foam to all exterior walls, and insulating in the basement. This was all done in 1 day and they cleaned up after themselves. I would highly recommend them."

"These guys came out right away, gave me a fair price and did the job great ! The toughest part was removing old insulation, getting it out of my house and cleaning it all up. They did all that and sealed up my basement tight ! Using their foam insulation they filled in all gaps. And they did it in one day ! We now notice our house stays a little warmer and no more mice ! Kyle and his crew were fantastic and I recommend them highly. -- Alan B - Sun Prairie"

"Specific project was attic, dense pack, and foam insulation. Very clean, friendly, and professional crew. Took the time to explain what they were doing, why, and what was wrong with what they found. Did a Focus on Energy assessment along with this work, recommended by Premier North, to make sure we let the science dictate the work. Very impressed with my overall experience."

"Travis, Logan and Jaxon were very professional in their work and cleaned up after. Great group of men to work with and I highly recommend Koala. Also had a room fan installed. None other of the estimates I had offered a fan. Another feature Koala offered and installed was an insulated zipped hatch cover over the entrance cover into the attic to completely seal any air leakage. Highly recommend Koala"

"Quick and efficient and did the job the way they said they would"
