What is it?
Post-remediation translates to “after initial mold removal”, and the inspection process can also be referred to as a clearance testing or a verification survey. The post-remediation clearance testing consists of a visual evaluation as well as the professional assessment of mold-causing factors, such as humidity and poor indoor air quality. The clearance testing includes a collection and analysis of air samples from the designated area. Evidently, the goal of the verification survey is to ensure that mold removal was performed correctly and the designated area is safe for the occupants.
Similar to the original mold testing, the samples of indoor and outdoor air are sent to the laboratory to closely examine and compare the levels of mold spores. Additionally, a qualified mold professional takes pictures of the previously contaminated area for the visual record and assessment. It is recommended that the clearance test is carried out by the same company that performed the original testing and removal to ensure the consistency of methodology, thus, greater accuracy of the results.
Why is it necessary?
Even if the area looks generally clean after mold remediation, it can’t be a guarantee of the total elimination of the microscopic mold spores. Verification testing absolutely needs to be performed within 24-48 hours after the initial mold removal. Within the given time frame, the area should not be ventilated to ensure the accuracy of indoor air samples. Mold testing following mold remediation provides a scientific verification that the mold problem has been eradicated, as well as providing the occupants with peace of mind.
