High Levels of Moisture in the Crawl Space and the problems it causes in Phiadelphia, PA, Trenton, NJ, and nearby areas.

Every time the Relative Humidity levels in the crawl space reach at or above 60%, the perfect environment for smelly mold and dust mites to thrive in is created. Warm and humid environments are also inviting spaces for termites, carpenter ants and other pests and wildlife.

Vented and untreated crawl spaces tend to be humid throughout the year because they get moisture from two sources: groundwater and the humid outside air constantly entering the crawl through vents.

Encapsulating the crawl space and providing proper drainage takes care of groundwater intrusion. Covering the vents takes care of outside air infiltration. However, there is a third source of moisture that needs to be addressed: moisture condensation. Very common in crawl spaces with HVC ducts and pipes, condensation happens when there is a difference in temperature between the crawl space and elements within it, and the outside. For example, an air conditioner duct running cold air in a hot summer day or a pipe of hot water running in a cold winter day.

Dehumidification: the definitive solution for crawl space mold problems


The only way to keep your crawl space healthy year-round and maintain Relative Humidity (RH) at safe levels is by running a good, energy-efficient dehumidifier.

The best options are models that were specifically designed for crawl space environments rather than generic, hardware-store bought portable models.
