Chances are that the crawl-space/foundation wall of your house doesn’t have enough vents, therefore, provides inadequate ventilation for your crawl-space. This can lead to wood decay resulting from abnormally high moisture in your crawl-space.As discussed in a previous article, ventilation, air movement, helps to remove moisture from spaces, and most building codes normally require ventilation, which will remove the moisture, especially in those areas prone to damage from moisture.

The building Heating, Ventilation, and Air Conditioning, HVAC, system helps to remove most of the moisture in the conditioned living spaces, but typically, attics and crawl-spaces are not conditioned. These two spaces depend almost exclusively on natural ventilation to remove moisture.

The case study example, in the previous article, dealt with a major crawl-space problem, and for the time, the articles’ focus will be on crawl-spaces and the humidity there. Attic moisture and ventilation will be addressed in later articles.Checking building codes, as far back as 1963, has revealed that crawl-space ventilation has been required at the rate of 1 square foot of net, free air area, ventilation area for each 150 square feet of crawl-space floor area.

Using automatically closing vents, and evenly spacing the vents around the 30’x50′ building, locates one vent every seven feet. Count the vents in your foundation wall. Do you have enough? Chances are that your house has crawl-space vents installed every twelve to sixteen feet, which is probably inadequate for the crawl-space area.
