"Rick was the only contractor to reply to my call for an estimate the same day. He scheduled the work promptly and showed up on time. I have hired him twice: Blown in insulation in the attic in April and recently Spray Foam on my basement rim joist. In both instances Total Comfort did a great job. Our house is much cooler this summer with the additional insulation in the attic. I would hire them again. Thanks Total Comfort !!"
