The document that proves the mold job is actually done.
Post-remediation verification is the independent check between 'the remediator says it's finished' and 'you can prove it.' Here is the deliverable, what it verifies, and what happens when a clearance fails.
Short answer
Mold clearance testing — post-remediation verification, or PRV — is an independent inspection performed after remediation, before containment comes down. The verifier confirms the moisture source is corrected, the work matches the written protocol, and the area is visibly clean and dry, with clearance sampling when the protocol specifies it. You receive a written clearance report and letter; if the area fails, the report says exactly why and the remediator corrects it under the same protocol.
What you walk away holding
Clearance is a document product. This is what Sterling's verification produces:
The clearance report
A written post-remediation verification report: what was checked, moisture and visual findings in the work area, lab results when sampling was specified, and a clear pass or fail conclusion tied to the remediation protocol.
The clearance letter
A concise letter you can hand to a buyer, landlord, insurer, or attorney stating the work area passed verification — the document transactions actually ask for.
The evidence behind it
Photos and readings from the verification visit, retained with the report. If anyone questions the clearance later, the record answers.

Four things a real clearance checks
A drive-by air sample is not a clearance. Verification is a comparison of the finished work against the moisture cause and the written protocol.
The moisture problem is actually fixed
Clearance starts with the cause, not the mold. If the source that fed the growth still reads wet — a slab edge, a supply line, an AC condensate path — the remediation is not done, whatever the containment looks like.
The work area matches the protocol
Florida remediation should follow a written protocol. Verification checks the completed work against that scope: materials that were to be removed are removed, cleaning steps were performed, and the area is dry, clean, and free of visible growth and debris.
The air and surfaces support clearance
When the protocol specifies sampling, clearance sampling compares the work area against the outdoor baseline and unaffected areas. The IICRC S520 standard frames the goal as returning the area to normal ecology — Condition 1 — not to some impossible zero.
Containment came down in the right order
Verification is meaningful only if it happens before the containment and negative air come down — after teardown, the work area mixes with the rest of the building and the result no longer isolates the remediated space.
What happens when the area doesn't pass
Nobody advertises this part, which is exactly why you should understand it before you hire anyone.

The report says exactly why
A failed clearance is not a shrug — the report identifies the specific condition that failed: elevated counts dominated by water-indicating types, visible dust or debris in containment, moisture still present at the source, or scope items from the protocol left undone.
- 2
The remediator returns under the same protocol
Failure sends the job back to the remediation contractor to correct the identified items. You should not be quoted a new project — the original protocol still governs, and the correction is part of completing it.

Re-verification, same standard
After correction, the verifier re-checks the same criteria. Clearance is issued when the area passes — not when the schedule gets tight.

Your leverage is the paper
A written failed-clearance report is what protects you in a dispute with a remediator, a seller, or a carrier: it is dated, specific, and produced by someone with no stake in the remediation invoice.
A failed clearance is not a disaster — it is the system working. The alternative is the containment coming down over a work area that was never actually finished, and the problem returning behind fresh paint. The independence of the verifier is what makes the fail honest: Sterling performs no remediation, so a failed clearance costs us nothing and protects you completely. That separation is not a slogan; it is Florida law.
Clearance testing questions
Is clearance testing required in Florida?
No statute forces a clearance test on every job. But Florida's licensing law (§468.8419) deliberately separates assessment from remediation, and lenders, insurers, buyers, and attorneys routinely require independent verification before they treat a mold problem as resolved. In practice, remediation without clearance is a job you cannot prove was finished.
Who should perform the clearance?
Someone other than the company that did the remediation. A remediator passing their own work is the exact conflict the law was written to prevent. Sterling performs verification only — we never remediate, so a pass from us certifies the work, not our own invoice.
How soon after remediation can clearance happen?
As soon as the work area is complete, dry, and still under containment. Verifying before containment teardown is the correct sequence; scheduling it in advance with the remediator avoids the tear-down-too-early mistake.
What does clearance testing cost?
It depends on the size of the work area and whether the protocol specifies clearance sampling. Sterling quotes it in writing before the visit — request an estimate and we respond with scope and price.
