We had insulation work performed by Dan and his crew from Dr. Energy Saver on two houses. They installed radiant barrier foil and cellulose insulation to the attic of one, and added cellulose and built a floor storage platform in the attic of the other. It was a very positive experience; they were very attentive to our requests and helpful in recommendations. It took a little longer than expected to perform, but the work provided was excellent and the amount of insulation they blew in was better than the R-value we had discussed. Overall they did a great job and had very competitive pricing. I couldn't be happier with the results.
