  • "We called on Proac to decontaminate an occupied dormitory room. A water leak caused mold growth on the walls and carpet. All the occupant’s possessions had to be removed, decontaminated and stored in a trailer while the work was completed on the room. Again, this project was completed in a professional and timely manner."
