The team from Northeast Air Sealing were very accommodating and easy to work with. The job entailed blowing in cellulose insulation into all exterior walls of our 2400sf house as well as the finished rooms in the attic. There was some initial consideration of the best access being through the inside walls as we were getting new drywall installed but the team decided to go through the exterior of the house instead. While they did a good job, they did break a number of the siding shingles. The owner of the company has offered to come back and assess the damage and fix what he can. I wish they accessed the walls from the inside instead of the outside! Regardless, they did a great job, really got in there in the attic and it's made an incredible difference.
