"I requested an estimate for blowing insulation into my attic. Jim came out once to do an assessment, and offered a reasonable estimate. We scheduled installation. He returned on my request after I removed the existing insulation to reassess the attic. It was determined that there was already insulation blown under the floor, and Jim stated that he would not recommend any further work. Jim did not charge me for the multiple visits for assessments, and was very gracious about the necessity of canceling. I would recommend his services without reservation."

"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"

"Everyone at Comfort 1st are wonderful to work with ! I recently got my attic insulated with them. Overall, very pleased with team and the work, I would highly recommended them. I received several quotes from competitors, but, David from Comfort 1st, was the only one to detail out all aspects of the job and was thorough in explaining the process. Mike was also great to work with and really knows his stuff. The crew who came onsite did a wonderful job in preparation and cleaned up once they were done. Overall, great communication with all team members. Once again, great company, would highly recommend them."
