We were going to have our heating ducts cleaned by Direct Energy and when they came in to do the job, on inspection the serviceman found asbestos around three ducts leading through the floor in between the walls. When Asbex came to remove the asbestos, the serviceman explained exactly what he would be doing and how he would package the refuse. he was courtious and after repeated tries, he would not stop calling me "sir". He was particularly sensitive to my familys environmental sensitivities. I would recomend them to family and friends.
