"It's hard to know about the quality of the work since I wasn't up in the attic with him. Would have been nice to have before and after pictures so I could see the amount of new insulation blown in. I just have to take Jasons' word for it. His cost was about 30% lower than the competition I got bids from. Overall satisfied."
