Before and After: Crawlspace Mold Remediation Project

 Photo taken during the initial inspection after insulation removal. Visible microbial growth is present on the subfloor. The black, yellow, and white discoloration indicates multiple types of microbial growth. 

 Before remediation. Although it resembles fire damage, this was microbial growth caused by a hot water line failure. No dry rot was found, so demolition was minimal and remediation began immediately. 

Same bay post remediation. Some staining remains, but testing confirmed the microbial growth was successfully removed and the area is safe. 

In this project, the homeowner elected to have an encapsulant applied for aesthetic purposes. Encapsulation is optional and should only be performed after proper removal and remediation of all contaminants. 

 This photo shows our containment chamber for the affected area. Negative pressure is created inside the chamber and continuously monitored with a manometer to ensure airborne particulates remain contained within the work area. Note the particulates visible in the air, without proper containment, these contaminants could migrate into unaffected areas of the home. 

The silver flex ducting in the background is connected to a HEPA negative air machine, designed to filter 99.97% of airborne particles down to 0.3 microns.
