High humidity levels are a nightmare for your crawl space. These can lead to fungal growth, wood rot, and floor system issues. Dehumidifiers are crucial in these circumstances. These are prescribed with an encapsulation to help regulate the humidity. Dehumidifiers cycle the air through a filter and collect the water that is present. That water is pumped out of the crawl space. Dry air is then circulated back out resulting in a constant and stable environment for your crawl space.
