Post-Remidiation Verification
PRV is an independent check after cleanup is completed to confirm the space is ready and safe for re-occupancy by documenting moisture control, containment, cleanliness, and any remaining concerns; Puritas provides a clear, evidence-based summary and next steps if anything needs to be addressed.

Mold remidiation
After moisture is corrected and HEPA cleaning is completed, clearance confirms readiness.
Water loss
(Cat 1-2)
After drying targets are met and removals are completed, verification confirms stability.
Contaminated water (Cat 3)
After disposal, cleaning, and disinfection are completed, clearance supports safe return.
Fire or smoke cleaning
After soot and odour work are completed, verification checks residual impacts.
Asbestos or lead abatement
After final cleaning is completed and before containment is removed, clearance supports re-occupancy.
Major renovation or dust containment
After demolition/sanding and deep cleaning are completed, verification checks dust control.
PRV
Triggers
Remediation is completed after an incident and you need independent confirmation that the affected area is ready to reopen; we check moisture, contamination, smoke residue, hazardous dust, or heavy renovation dust, and PRV helps verify that drying, containment, and cleaning were effective and safe for occupancy.

What we investigate
To confirm the space is ready for re-occupancy by verifying dryness, cleanliness, and containment, and when mold is involved, to verify Condition 1 (normal fungal ecology), meaning only background-level spores or fragments consistent with a comparable normal indoor environment.
Scope + pass criteria
Affected areas, boundaries, and acceptance criteria documented up front with the cleint and remidiation company.
Cleanliness + odors
debris removed, surfaces visibly dust-free, no abnormal odors, optional glove/wipe checks.
Moisture control
moisture mapping and confirmation drying targets are met and sources corrected.
Containment effectiveness
Barriers, negative pressure, and cross-contamination controls verified against scope.
HVAC + documentation
Filtration/returns reviewed as relevant, with a clear report and any corrective actions.
What to expect: Typical visit 60–120 min • Verbal or written report • Prioritized recommendations
