"They arrived on time, it took about 2.5 hours, there is at least 18 inches or more of insulation, and I cannot wait to see the difference in the temperature in the house! Next weekend will be to do blown in insulation in the walls! Many thanks to owner Mike DePasquale and Energy Consultant Kevin Sweeney!"
