We had our entire attic sprayed with insulation. The owner came out and gave us an estimate. He also was very helpful because he told us some other ideas to help with out heating and cooling such as installing bathroom fans. He went through the process step by step and made sure we knew that there might not be a ton of difference in how the house will insulate but that it would help some. Once they did the insulation we had a bit of a problem because his workers sealed up the attic vents so there was no circulation in there. Once we called him he came out right away and fixed the problem.
