Objective proof the job is done
Visual inspection is the first check after remediation, but some situations call for objective results: a property that was used to make methamphetamine, a home where fentanyl was present, a tenant or buyer who wants assurance, or an insurer or lender that requires documentation. Clearance testing provides that.
Why independent testing matters
Results carry more weight when the person who collects samples isn't the company that did the cleaning. We coordinate testing by independent, qualified professionals, such as industrial hygienists, certified drug lab assessors or environmental consultants, and accredited laboratories. In states that regulate drug lab cleanup, the regulations often specify who may perform final sampling and what standards apply.
Types of clearance testing
- Drug residue sampling: surface wipe samples for methamphetamine, fentanyl or other drugs, compared to state standards or agreed targets
- ATP testing: a fast measure of organic residue on surfaces, useful as a cleaning verification tool
- Air and surface sampling for specific concerns, such as mold, when ordered by a consultant
- Moisture verification after water and sewage events
How it works
- Agree on the standard. Which tests, which locations and what results count as passing, before work starts.
- Remediate to that standard.
- Independent sampling by the third party.
- Laboratory analysis with chain-of-custody documentation.
- Results report delivered to you. If an area fails, it's cleaned again and retested.
State-regulated drug labs
Tennessee, Kentucky, Arkansas, West Virginia, North Carolina and Virginia all have rules or guidelines for properties used to manufacture methamphetamine. Requirements differ by state, and we plan clearance to match.
Common questions
Who pays for clearance testing?
Usually the property owner or insurer. We include it in the scope so costs are clear up front.
What happens if a test fails?
The area is cleaned again and retested. That's why we agree on targets before remediation.
Is testing required?
Only in certain situations, such as some state-regulated drug lab properties. Elsewhere it's optional but often valuable.
