What PRV Is (and Why It Matters)
Post-remediation verification (PRV) confirms that the mold source was addressed, affected materials were removed or cleaned, and the area is dry and safe to rebuild. It is far cheaper to verify now than to reopen walls later.
PRV Checklist
Moisture and Materials
- Moisture source fully repaired
- Wet materials dried to acceptable levels
- Porous materials removed where required
- No ongoing condensation or leaks
Visual and Cleanliness
- No visible mold growth or staining
- Dust and debris removed from surfaces
- HEPA vacuuming completed
- No musty odor remaining
Verification Steps
Independent Verification
For medium and large projects, consider hiring an independent inspector for verification. Third-party oversight reduces conflicts of interest and provides written documentation that can be used for insurance or tenant disputes.
