"Owner, Jim Mass, responded promptly to set up a personal visit to explain the process and options to myself and my wife. Once the work was scheduled; crew arrived on time and work, including total clean up, was completed within the estimated time of less than day. All was completed within 1 week of the owner's initial visit. I would definately recommend Insulation Specialists to friends, which I have done."

"Thermal Comfort exceeded my expectations for scheduling my project, and the quality of their work is excellent. They did a great job of protecting everything prior to application, and the cleanup was done well. As a retired architect and professional engineer, I expect and watch for quality, and was very pleased with this company. I recommend this company to anyone requiring a foam insulation project of fine quality and a good value."

"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"
