Spray Foam Didn't Help
The spray foam that Chuck had previously installed didn't stop mold from growing on the joists.
Relative Humidity Under the Home
The relative humidity under the home was too high. It created the perfect environment for mold to grow.
Before the Crawl Space Encapsulation
Though the soil may look dry, it's not. The earth is constantly releasing moisture vapor and it gets trapped in the crawl space. The wooden subfloor, joists and beams absorb - mold grows, and the wood eventually rots.
After Lowcountry Basement Systems
The crawl space was encapsulated, a SmartDrain was installed and a SaniDry Sedona dehumidifier was installed to lower the relative humidity.
