Like many homes, our cabin is built over a soil crawl space. While crawl spaces offer simple construction and access to the underside of your home, they provide little protection from the environment, and can lead to structural and air quality problems within your home.
Standing water, high moisture levels, soil gas, dust and an abundance of rodents and other critters are common in unsealed dirt crawl spaces.
Traditional thinking (and building codes) promoted ventilation of crawl spaces to circulate outside air into the crawl space and control moisture.
Unfortunately, ventilation of crawl spaces often does more harm than good. In many climates, ventilation can make moisture problems worse by introducing an unending supply of relatively humid outside air into the crawl space that can form water once in contact with the cool surfaces within a crawl space.
