I live in a newly contructed home and after it was finished there was dust everywhere. I would clean the floors and furniture and within a few days it was back. I could even see the dust in the air on sunny days. After Clean Air Specialties came in I noticed a huge difference in how much dust accumulates. The guys that came in to clean were very professional. They laid tarps down and even wore covers on their shoes! I was very impressed with the job and highly recommend them to anyone.
