Crawlspace Moisture Control in Wilmington NC
The necessary relative humidity level is determined by the coldest surface area in the structure. In Northern climates the foundation can be considered the coldest surface during humid periods because the ground temperature remains approximately 52 degrees Fahrenheit. In the South, portions of the air conditioning duct work probably represent the coldest points. The air in the structure must be dehumidified to a dew point (saturation temperature) lower than these coldest spots. Dehumidifiers remove humidity from the air. Since moisture is one of the critical requirements for mold growth and can be controlled, it is a logical strategy to dry the affected structure and the air within it to help reduce or eliminate mold growth. In order to be effective, the humidity levels in the structure must be aggressively lowered and maintained.
