Professional Steps for Mold Cleanup in a Crawl Space

6/14/2017 (Permalink)

• 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. 
• "Meter" the floors in the home, assessing moisture levels to determine where unseen mold inside the home might exist. 
• Consider calling in a third party - e.g., SERVPRO Southeast Portland - 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. 
• Use a HEPA filter or air scrubber in the living area to reduce contamination. 
• 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. 
• 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. 
• Call in a third party - such as a SERVPRO Southeast Portland - 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.
