"The team at Dana Insulation is top notch. From Tom in sales to the installation team everyone was courteous and professional. They put down protective plastic on the floors so as not to get any dirt or insulation on the floors. Did a great job cleaning up after the job as well. Thank you very much Dana Insulation!!!! I would definitely recommend this company!!!"

"From the consultant, Joe, to the five men that came to my home, I was impressed with the professionalism and respect for my home. Tyler,Jake, Chuck, Dustin and Scott made sure everything was installed with exceptional precision and attention to detail. It took a full day to accomplish. They arrived on time, and cleaned up afterwards throughout my home and garage. Protective covering on their feet with additional protective materials on my floors and walls were used. Their care and respect went above and beyond. The product is eco friendly, fire retardant and mold resistant. And my home is warm and cozy. Removing all the old and filthy insulation that is 37+years old and leaving my attic space and foundation areas sealed and cleaned just makes everything feel buttoned up and tight. Highly recommend! Special shout out to Makaila and Katie, office personnel that kept in touch and applied for eligible rebates to help keep costs down as well. Thank you!"

"I hired Thermal Solutions to spray foam insulate my pole barn and they did an excellent job. I got 4 quotes and theirs was the cheapest. They say never go with the cheapest, but I did because I wanted to support a veteran owned, local business, and after talking with Niko, I felt confident the job would be done right. I'm really glad that I did because they came when they said they would, they did it just the way that I wanted, and they did a great job of cleaning up when they were done. I highly recommend them for open and closed cell spray foam insulation jobs!"
