These homeowners came back from a trip to find standing black water, black mold growing on the walls and furniture, bugs everywhere, and a terrible stench. The interior of their condo was destroyed by a sewage backup in the condo above them that backed up through their kitchen sink and flooded the house.
In mold remediation, containment barriers keep airborne mold spores from cross-contaminating other areas of the site during the removal process. Mold reproduces via spores that are released into the air and require moisture to survive. In asbestos abatement, containment prevents asbestos from drying out and releasing fibers into the air.
