It depends on your policy and what caused the problem. Sudden pipe bursts usually get covered, but slow leaks might not. Some policies exclude mold entirely unless you bought extra coverage. Environmental liability insurance offers better protection. Document everything immediately after water damage. Call your agent before problems get worse.
Post Remediation Clearance
Why Do I Need Post Remediation Clearance?
Post remediation clearance ensures mold was properly removed and hasn't spread during cleanup. Independent testing by certified inspectors prevents fraudulent practices, verifies contractor work quality, protects property value, and provides documented proof for insurance claims. Without clearance, hidden mold may resurface, causing recurring health issues and expensive re-remediation costing tens of thousands more.
Who Should Perform Post Remediation Clearance?
Post remediation clearance must be performed by certified ACAC third-party mold inspectors with no affiliation to the remediation company. Using independent inspectors prevents conflicts of interest and ensures unbiased results. Remediation companies offering their own clearance testing violate ethical codes. Only AIHA accredited laboratories should analyze samples to guarantee accurate, trustworthy contamination-free results.
How Long Does Clearance Testing Take?
Post remediation clearance testing takes 2-3 hours for residential properties, including visual inspection, air sampling, surface testing, and moisture verification. Laboratory analysis requires additional 3-5 business days for results. Properties pass when spore counts meet acceptable levels and no visible mold remains. Failed clearances require additional remediation before retesting, extending overall timeline.
Can the Remediation Company Do Their Own Clearance Test?
No, remediation companies cannot perform their own clearance testing due to conflicts of interest and ethical violations. IICRC standards and industry codes of ethics require unbiased third-party ACAC certified inspectors conduct all clearance testing. Companies offering both services often provide false results to pass inspection, compromising your safety and leading to mold resurfacing later.
How Long After Remediation Should Clearance Testing Occur?
Clearance testing should occur immediately after remediation completion, typically within 24-48 hours once cleaned areas are dry and containment barriers remain in place. Testing too early while surfaces are wet produces inaccurate results. Contractors should not remove containment, apply coatings, or begin reconstruction until receiving official clearance approval, ensuring no contamination persists before restoration work begins.
