What can excessive moisture in a crawl space lead to?

Excessive moisture in a crawl space can lead to mold growth and wood rot, which are significant concerns for the integrity of a building. High humidity levels and standing water create an environment conducive to mold spores to thrive, leading to health issues for occupants and damage to building materials. Additionally, wood rot occurs when moisture penetrates wood structures, weakening the materials and potentially compromising the structural stability of the building. Maintaining appropriate moisture levels in crawl spaces is crucial to preventing these problems and ensuring a healthy living environment.
