Post-Remediation Evaluation (PRE)
Once remediation work has been completed, the next step is verifying that the documented objectives have been met.
A Post-Remediation Evaluation (PRE) is conducted after remediation to assess whether moisture conditions have been corrected and whether remediation efforts align with established remediation objectives and recognized industry guidance.
Many homeowners are familiar with the term “clearance testing.” The IICRC term for this process is Post-Remediation Evaluation. The goal is not simply testing — it is confirming that the remediation process achieved its intended outcome.
Why a Post-Remediation Evaluation Matters
Remediation is only complete when defined objectives have been met.
Without an independent evaluation, property owners are often left relying solely on the remediation contractor’s assessment of their own work.
A PRE provides:
Independent verification of remediation efforts
Evaluation of containment and final cleaning
Confirmation that moisture sources have been addressed
Environmental sampling when appropriate to confirm defined clearance objectives
A Post-Remediation Evaluation may be performed following remediation completed under our protocol or under a plan developed by another party.
The evaluation focuses on current environmental conditions and whether remediation objectives have been achieved.
For a PRE to be meaningful, it must occur at the proper time.
Best practice is for the Post-Remediation Evaluation to take place after remediation work is complete, but before containment is removed and before any rebuilding begins.
Evaluating the work prior to containment removal allows any identified deficiencies to be corrected within controlled conditions — avoiding disruption, additional demolition, or repeated reconstruction later.
What a Post-Remediation Evaluation May Include
Depending on the scope of remediation, a PRE may involve:
Visual inspection of remediated areas
Verification that containment remains intact at time of evaluation
Moisture re-evaluation of previously affected materials and areas
Environmental sampling when defined clearance objectives require it
Comparison of current conditions to the original remediation protocol
Sampling is performed only when appropriate and when it aligns with the defined remediation goals.
Important Considerations
A Post-Remediation Evaluation reflects environmental conditions present at the time of evaluation. It does not guarantee future conditions.
If conditions are identified that do not meet defined objectives, findings will be documented so that corrective action can be taken before the project is considered complete and containment is removed.
Our role is to assess environmental conditions based on documented standards. We do not supervise remediation crews or assume responsibility for contractor performance.
When to Schedule a PRE
A Post-Remediation Evaluation should be scheduled:
After remediation work has been completed
Before containment is removed
Before reconstruction or building materials are replaced
When written verification of remediation completion is desired
Scheduling the evaluation at the appropriate stage helps protect your investment and ensures remediation objectives are confirmed before moving forward.
Next Steps
Post-Remediation Evaluation is typically discussed during protocol development or remediation consulting.
We begin with a complimentary consultation to confirm timing and scope before scheduling an on-site evaluation.
