The water in these materials can keep the humidity at the surface high enough to support fungus and mildew 80% relative humidity (rh) is a commonly used threshold. And when these materials get wet, they tend to stay wet. Porous materials such as wood and insulation can absorb a lot of water. Crawlspace Vents and Problems With Enclosed CrawlspacesĮnclosed crawlspaces are usually contained by a solid concrete or masonry foundation wall that extends down to footings just below the frost line. Careful design and construction to mitigate the entrance of moisture and condition the space is your best line of defense. Gaps in the flooring will also admit moisture from the crawlspace below, which will affect indoor air quality. If the floor structure above the crawlspace is uninsulated, heating and cooling losses will result. If improperly constructed, the crawlspace can affect the comfort inside the house, as well as the home's energy consumption. Is Crawlspace Ventilation the Answer?īut does crawlspace ventilation really provide the desired drying and moisture control? Are there other more effective methods for keeping the crawlspace dry? And what about the energy impacts of venting the space directly below the main living area in a house?

Traditionally, the most common method of dealing with moisture in crawlspaces-and the one longest endorsed by building codes-has been to ventilate them. Enclosed crawlspaces can be a magnet for moisture, mold, and rot.
