All went according to plan except the use of the hepa vacuum. We spent the night away to minimize problems for my husband and he has HAD NO BREATHING DIFFICULTIES!!!
I can't say yet if the insulation made a difference as this has been an exceptionally cool summer for us. If I can post something when it gets cold, I will add to this post.
Had to call them back months later when I found an area they missed. Out they came and quickly corrected the error (which was in a hard to get to spot in the crawl space. They even foamed the pipes to/from the hot tub as they went - showing thoughtful desire to a goal of insulation not just a work order.
