  Crawl Space

Missouri Crawl Space Humidity

Vented dirt crawl spaces in Missouri are naturally cool, usually maintaining an average temperature in the low fifties year round.

However, during the hot, humid summer months in the St. Louis region, crawl space vents allow warm, humid air in. Because cooler air holds less moisture than warm air, the relative humidity in the crawl space raises dramatically.

Once the relative humidity reaches 100%, the air in the crawl space cannot hold anymore moisture. The extra moisture appears as condensation on the ground, floor joists, insulation, and any items stored in the crawl space.

This condensation, combined with the organic material found in wood, boxes, insulation, and other objects found in a crawlspace, creates a perfect environment for mold to grow. Any organic surface will quickly be covered in mold and rot, and mildew will form wherever it can. As mold grows, it will send millions of spores into the air. Insects such as termites will enter the basement and feed off the rotting wood. Rodents move into the home and feed off the insects as well, creating an even larger problem. Dust mites live and thrive in the humidity, sending their fecal matter into the air.
