Clearing visible mold growth from structural surfaces is only one step in the restoration process. Because microscopic mold spores float in the air, confirming that a space is safe for re-occupancy requires formal Post-Remediation Clearance Testing.
1. What Is Air Clearance Testing?
Following physical remediation and HEPA air scrubbing, an independent, third-party NYS-certified Mold Assessor enters the contained work area. The assessor collects high-volume air cassette samples and surface lift swabs, which are processed by an accredited laboratory to verify that airborne spore counts match clean indoor or outdoor baseline standards.
2. Why Clearance Documentation Is Essential
-
Legal Compliance: A formal Clearance Certificate proves to landlords, lenders, co-op boards, and prospective buyers that the remediation was executed per NYS Article 32 guidelines.
-
Real Estate Closing Protection: Prevents real estate transactions from stalling due to unverified environmental disclosures during property sales.
-
Verification of Air Quality: Confirms that all microscopic spores disturbed during structural teardown were captured by HEPA filtration equipment.
