Josh at Air Tight Solutions was amazing. They could have gotten money out of me by performing test that I thought code was requiring me to have done but Josh was very honest in letting me know that our building was exempt from certain test being done due to the building having foam insulation. I couldn't be more grateful and you are definitely dealing with honest people at ATS.🥰Posted on Google![]()
