Clearance Testing

Clearance testing is performed after mold repairs or remediation has been completed. This is may have been due to a plumbing leak, water intrusion or a high moisture situation when mold growth has occurred.

Many insurance companies, financial institutions and real-estate buyers will require clearance testing before payment is made. The test confirms that the repairs have been completed and all issues have been eliminated.

Home owners have the option of hiring an independent inspection company to perform the testing other than the company that did the work. This helps to assures the area is safe, has been properly cleaned and that compliance has been met.

Safe Clearance Testing Protocol 

Windows and doors need to be shut the day before inspection is scheduled and during the inspection. Hot air ducted heating and cooling systems need to be shut down during inspection.

Mold debris and materials removed.

Air scrubbers off at least 24 hours before inspection.

Plastic containment enclosure should be left intact to ensure it had been properly installed.  If clearance test fails to pass, the elevated mold spores that were contained by the enclosure could drift into the surrounding cleaner air and cause new contamination.

Recommended inspection should contain both air and dust sampling. This makes sure that air borne and settled dust does not still contain highly elevated mold spores and that the area is safe and clean.
