The biggest problem with moisture is that it can lead to rot, decay, and mold underneath your home and this is something you do not want. In addition to the health problems that mold causes, the fixes for a mold or foundation problem can get costly. Another problem which will be just as costly over time is that the air from the outside seeps into your home which means it costs more to heat your home in the winter and costs more to cool it in the summer.
