Containment is Necessary for Mold Remediation
If restorers encounter mold growth during the course of a restoration project, water damage restoration activities that may disturb the mold should stop until the area of existing or suspected mold contamination is "contained". A containment barrier can consist of using 6 mil poly plastic sheeting sealed with tape to completely isolate the work area, as shown in picture. Disturbing mold during the remediation or cleaning process will inadvertently cause mold spores to spread and will cause cross-contamination, which is the spread of contaminants from a contaminated area to an uncontaminated area. Without a proper containment barrier set up the mold spores might become airborne and spread throughout the home to places where mold may not have been before.
