Why didn't I insulate years ago!! My oil consumption has decreased by more than 30% in comparable weather as compared to pre-insulation days. My house is so much more comfortable -- no longer are our walls freezing to the touch, and the noise level from the street is noticeably decreased. I no longer live in fear of freezing pipes. This is a family business, and they are friendly and responsive. Make sure to take pictures off the wall, because they will fall off. The house also gets very dusty from the cellulose. I researched cellulose vs. fiberglass quite extensively, and although the cellulose was more expensive to begin with, the research definitely showed it to be better than the fiberglass in the long run.
