I did indeed hire Mr. Lucas. I have 5 attic spaces in my house, I asked him to do just one, about 650 square feet. The dramatic difference in temperature in that room and the cooling efficiency below that room was really incredible. I have kept daily temperatures on all the rooms and the difference is remarkable. He is going to do the rest of my house, around another 4,000 square feet in about 10 days. The savings in energy and the comfort level far outweigh the costs. The insulation is not cheap but, it's much better than paying high energy bills. I am referring him to my family and he will help insulate some of our properties.
