What is containment?

Containment is nothing more than a system of barriers and other engineering controls designed to contain the mold contamination to the designated work area.  Contractor’s typically erect 6 mil poly sheeting (visquene) around the work area and then places the “containment” under as slight negative pressure with HEPA filtered air movers. While the mold spore concentration within an area may not be too high at the beginning of a project, it will quickly climb as moldy materials are disturbed. The containment is designed to prevent those mold spores from moving to unaffected areas of your home.
