201903.21 0 What is a PRV Clearance? in Public Adjusters Post-Remediation means “after mold has been removed”. A post-remediation verification survey (sometimes called clearance testing) includes a visual inspection and moisture assessment of the construction materials that were part of the remediation work, and air quality testing inside the work area. Both are necessary to properly assess whether or not the mold remediation was successful. The purpose of Clearance Testing is to determine the success of the mold remediation efforts inside of existing containment areas to document the areas remediated are safe for occupants to safely enter.
