HEPA vacuuming areas of concrete and efflorescence with mold growth in it. (This is a pre and post process. HEPA vacuuming is a process of pulling all contaminates off a surface area. This process eliminates mold particles from a surface area with specific vacuums without contaminating the air quality of a livable space. HEPA vacuuming is normally done before and after to reassure no particles are in the space that was contaminated).
