Cleaning and Sanitizing
At this point in the remediation process the infested area is scrubbed with powerful antimicrobials to ensure the black mold colonies are destroyed. Then the structural wood and other materials are treated with sanitizers to prevent a recurrence of the infestation.
Drying and Restoring
Once everything has been cleaned and sanitized, the remediation service will need to dry out wet areas before replacing infested drywall or other components with fresh material. The drying might be done with powerful fans, or dehumidifiers to ensure that no pockets of moisture are left behind where the fungal infestation could once again gain a foothold.
After the drying, the owner’s possessions can be brought back. Any salvageable content would have been removed from the affected area early in the remediation process so that none of it could be infested.
Mold Clearance
When the remediation process is complete, a post-remediation verification (PRV) air test should be taken (like the test suggested at the beginning of the procedure) before occupants re-enter the premises. This will ensure that the property has a safe, healthful environment. It is best to check with your own state or municipal health codes to see what restrictions (if any) they have in place. In any event, testing is highly advisable because it may protect the property owner from any litigious actions that may arise later. There have been cases in which property owners were found to be responsible for physical ailments stemming from black mold.
Although some remediation services perform their own tests to make sure the job has been completed successfully, it is generally believed to be in the best interest of the property owner to hire a licensed third party to conduct the test, someone who has no vested interest in the outcome. The PRV test (also called a clearance test) shows that the mold infestation has been cleared out to at least a prescribed healthful level. Generally, the test should indicate that mold levels inside the premises are approximately equal to the outside air.
