After remediation, clearance testing is how you confirm the cleanup actually worked. An independent inspector samples the remediated area and an outdoor control, the labs run the numbers, and you get a MoldSCORE-based pass, marginal, or fail result in writing within 48 hours - the adjuster-ready report insurers often require before they close a claim and release final payment. For homes and commercial buildings across LA, Ventura, and Orange Counties.
Clearance testing - also called post-remediation verification - is the independent check that comes after the cleanup, measuring whether the remediated space is back to normal indoor levels.
When a remediation contractor finishes mold removal, water-damage mitigation, or smoke restoration, the work looks done. Clearance testing measures whether it actually is. An independent inspector visually checks the remediated area, then collects two air samples - one inside the cleaned space and one outdoors as a control - and sends them to the lab. Comparing the indoor result against the outdoor baseline is what shows whether indoor levels have returned to normal or are still elevated.
This is a verification role, and we keep it that way. We measure the result independently - we do not perform the remediation or certify the contractor's work. The lab data and the MoldSCORE comparison speak for themselves, which is exactly what makes a clearance report useful to a homeowner, a contractor, an adjuster, and a lender alike.
Post-remediation clearance is frequently a required step, not an optional one. Some states mandate that the company performing the clearance test is independent from the company that did the abatement, and insurance carriers often require an independent clearance report to close out a remediation claim and release final payment to the contractor. If your project is tied to an insurance claim, a lender, or a real estate transaction, an independent clearance test is usually what moves it to the finish line.
Clearance testing and mold testing use the same labs and the same air-sampling methods, and both are $349 with two samples included. The difference is the question they answer. Mold testing asks "is there a mold problem here?" before any work is done. Clearance testing asks "did the remediation work?" after it is finished, and the report is written and interpreted around that pass-or-fail outcome.
| Mold Testing ($349) | Clearance Testing ($349) | |
|---|---|---|
| Visual inspection + 2 air samples (indoor + outdoor) | Yes | Yes |
| BTLS spore trap + Eurofins MoldSCORE | Yes | Yes |
| When it happens | Before remediation | After remediation |
| Question it answers | Is there a mold problem? | Did the remediation work? |
| Report outcome | Species + spore counts | Pass / Marginal / Fail verdict |

Every $349 clearance test pairs an independent inspection with two lab-analyzed air samples and a clear pass-or-fail report.
Time on site: 45 to 75 minutes for most areas.
Labs: Eurofins and BTLS, the same labs as our mold testing.
Best for: Claim close-out, final payment release, and resale.
Your clearance test is run by a certified mold inspector who reads to a recognized industry standard, and your samples are analyzed by Eurofins (AIHA-LAP accredited, ID #173068) and BTLS (ASTM-standard methods, Tarzana). We measure the result independently, so the pass-or-fail outcome rests on objective lab data that everyone in the process can trust.
$349 flat for standard clearance testing, with two air samples included. The price you're quoted is the price you pay.
The clearance testing cost is $349 for a standard remediated area, covering the independent visual inspection, two air samples (one indoor and one outdoor control), BTLS spore trap analysis, the Eurofins MoldSCORE comparison, the Pass, Marginal, or Fail determination, and your adjuster-ready written report within 48 hours. Additional samples are $85 each when more areas need confirmation, and larger projects are quoted before we book.
That pricing is worth a direct look. Clearance testing around Los Angeles commonly runs $499 to $650, often with additional samples at $150 each. Our $349 includes two samples and the MoldSCORE verdict, with extra samples at $85 - more included, clearly priced, with the same accredited labs behind every result.

Once remediation is complete, tell us the scope. We confirm a time - same day inside our 25-mile core, next day everywhere else - and lock in the $349 flat rate.
We visually verify the remediated area, then collect one indoor air sample in the cleaned space and one outdoor control, with surface samples if an area needs confirmation.
Before we leave, we walk you through what we observed on site - in plain language - while the samples head to the lab.
BTLS runs the spore trap analysis (ASTM D7391-20) and Eurofins applies the MoldSCORE comparison of indoor levels against the outdoor baseline.
Within 48 hours you'll have the written report with a clear Pass, Marginal, or Fail verdict, ready for your insurer, lender, or records.
