Ecotelligent Homes removed the old insulation from our attic (which contained asbestos) and blew in the amount/depth of insulation that is recommended today. This was a huge undertaking because abating asbestos is a serious business. At every step of the process, from evaluating the insulation already in our attic, to explaining the process, to preparing the house, to removing the old insulation and installing the new, to monitoring and certifying the air quality in our home, everyone seemed to pay meticulous attention to detail, and was very serious about safety and compliance with state standands. Everyone responded to our questions and concerns with timely and complete answers. The company also removed our old attic fan, and changed the location of our attic access. We are very happy with their work.
