Had the guys from Duct Blasters out to clean our house yesterday. They were on time, very polite and knowledgeable about the service they were providing. I just installed hardwood floors and they took every precaution to make sure that they were not damaged. (drop cloths, removing shoes). They were very personable and fun to talk to. I had my home done last year with another company who showed me what was removed from our vents, and it was NOTHING compared to what these guys got out! It was amazing!! I would highly recommend Duct Blasters to anyone, and I have told everyone I know!
