I had Thor Construction come to my home to do air sealing and insulation. When they came to perform the scope of work, they give me the bid the same day. The other two firms took over a week to get their quotes to me. The crew came on time and worked most of the first day until they had to stop due to their needing to wait for the electrician to show up for the a bathroom fan installation. They came back the next morning and completed the job. Each time they completely cleaned up the work areas and were courteous and respectful. They ended up reducing my numbers on the blower test from 2460 to 1750. A big decrease largely attributable to the air gaps between the wall joists in the attic. I was pretty pleased and found that their pricing was in line with other firms for the same work.
