Post-Remediation Verification (PRV) & Clearance Testing

Independent verification after mold remediation. Once remediation work has been completed, EnviroProz evaluates accessible treated areas and relevant environmental conditions against agreed project criteria.

Independent Assessment

EnviroProz does not perform mold remediation, helping maintain separation between the contractor who completed the work and the assessor reviewing it.

Documented Findings

The written assessment identifies what was checked, any sampling performed, limitations and whether specified verification criteria were met.

Our Four-Stage Verification Process

  • 1. Visual verification: evaluate accessible treated surfaces, remaining debris, visible growth and apparent completion of the documented scope.
  • 2. Moisture screening: assess relevant materials and previously affected locations with appropriate diagnostic instruments.
  • 3. Sampling when indicated: collect indoor air or direct surface samples based on the project scope and verification criteria.
  • 4. Written results: document observations, laboratory findings when applicable and a clear pass, fail or conditional outcome against the defined criteria.

What Does a PRV Pass Mean?

A passing result means the specific inspected and tested conditions satisfied the established criteria at the time of evaluation. It is not a guarantee that every concealed area is free of mold, that all spores have been eliminated or that contamination cannot return.

When Should PRV Be Scheduled?

Generally after the contractor reports the remediation scope complete and before containment is removed or reconstructed areas are closed, when the protocol requires verification at that stage. Coordinate the sequence with the contractor and assessor.

Frequently Asked Questions

Is clearance testing always required?

Requirements vary by project, client needs and applicable agreements. Independent verification is often valuable when a documented remediation outcome is important.

Does clearance always include air samples?

No. Sampling is chosen according to the specific verification objectives, remediation scope and established criteria.

What if the work does not pass?

The findings identify remaining concerns and the areas requiring corrective attention. The remediation contractor can address those items before a new verification is considered.
