Clearance testing in Teaneck: what to know
Teaneck's predominantly single-family housing stock from the 1920s–1960s includes many homes with block foundations and original basement damp-proofing that degrades, admitting moisture during wet seasons.
The Overpeck Creek and nearby wetlands create elevated groundwater tables in portions of Teaneck — basement flooding from high water tables is more common here than in upland NJ communities.

Signs you need clearance testing
- Remediation has been completed and containment is still in place
- The written protocol specifies clearance testing as a completion requirement
- A real estate transaction requires documented proof of successful remediation
- An insurance claim requires certified clearance documentation
- The remediator has offered to perform their own clearance (this should be declined)
- A previous clearance test failed and re-clearance is required after additional work
How we handle clearance testing in Teaneck
Clearance testing is the final step of any IICRC S520-compliant mold remediation and the critical quality control measure that confirms the work was done correctly. The clearance test must be performed by an independent licensed mold assessor — the company or individual that performed the remediation cannot perform their own clearance test. This independence is mandated by the NYS 2015 Mold Law and is best practice in all markets.
The timing and conditions of clearance testing are specified in the written remediation protocol. Standard protocol requires that containment remains fully in place when samples are collected, that the HEPA-filtered negative air machine has been running for at least 4 hours before sampling, and that an outdoor control sample is collected simultaneously with indoor samples.
