In the winter of 2014 we hired HOTSHOTZ to do an energy audit on our loghome.The results were astounding as the air infiltration was coming from areas not detectable with the human eye and the old candle trick! When we received Mark Watkins professional audit and the recommended areas to insulate and caulk we then hired Mark and his excellent helper. Together they performed an efficient job of caulking and insulating all the area identified with his ‘heat’ camera. The team was very quick and did a wonderfully professional job. The energy company subsidized the cost of the repairs so that that was a great incentive to having the work done too.
