  1. Put the area under negative air pressure, by setting up an air mover on the outside of the home to draw air out from the crawl space - preventing the mold-affected air in the crawl space from traveling into the living area any further. 
  2. "Meter" the floors in the home, assessing moisture levels to determine where unseen mold inside the home might exist. 
  3. Consider calling in a third party - e.g., a Certified Mold Inspector (CMI) - to provide an independent visual inspection of the crawl space, and to take air samples in the living area to determine how much mold has entered the home interior. 
  4. Mold Containment/Air ScrubbingMoisture MeasurementDevelop a mitigation protocol adhering to the BSR-IICRC S520 Mold Remediation Standard and Reference Guide for Professional Mold Remediation.
  5. Use a HEPA filter or air scrubber in the living area to reduce contamination. 
  6. Before beginning the mold mitigation in the crawl space, build a containment around the interior crawl space access, and tape off the interior air vents. 
  7. If mold damage is extensive, remove the crawlspace-mold by [baking] soda blasting [along with blasting using ground walnut shells], followed by thorough HEPA vacuuming and vapor barrier replacement. 
  8. Call in a third party - such as a CMI - to again perform an inspection of the crawl space and take air samples in the living area, to ensure that everything has been completed properly.
