Humidity buildup occurs in a crawlspace through multiple sources from moisture evaporation through the earth, evaporation from water along with many other sources.
These sources come together to create excessive humidity levels.
The source for excessive humidity varies dependent upon many factors. Properly assessing the causes will allow us to locate and address all access points.
Properly controlling humidity will stabilize the crawlspace and prevent many of our common problems such as mold, structural harm and cupped flooring.
