How We Help With Post-Remediation Verification

After mold remediation is completed, verification testing by an independent third party — not the remediation contractor — is the industry-recognized best practice under IICRC S520 standards. Post-remediation verification (PRV) confirms that remediated areas have been returned to a normal fungal ecology, that spore counts are consistent with or lower than outdoor baseline levels, and that no residual elevated moisture remains to sustain future growth. Alchemist Mold Testing provides this critical final step with complete independence from any remediation contractor.

Our PRV protocol includes a thorough visual inspection of all previously affected areas for evidence of remaining growth or incomplete containment teardown, followed by air sampling inside and outside the work area and surface swab sampling from remediated surfaces. Samples are sent to an accredited laboratory, and a written clearance report is issued — or, if conditions do not yet meet clearance criteria, a detailed failure report identifying what remains to be addressed before retesting.

Clearance documentation is frequently required by mortgage lenders, real estate transactions, insurance carriers, and commercial property managers before a space can be reoccupied. Having an impartial, third-party clearance report from Alchemist Mold Testing protects all parties and provides lasting documentation that the remediation was performed to standard.
