Crawl Space Humidity

When your crawl space isn’t properly sealed, excess moisture and humidity from outside can easily make their way underneath the home. While you may not notice its effects at first, it will eventually make its presence known through dangerous mold or mildew growth and from many other types of damage.

Humidity is a measure of the amount of moisture in the air. This dense air will get into cracks and crevices of the footing and cause wooden supports, floor joists, and beams to deteriorate. This doesn’t just spell trouble for the structural integrity of your home; the rotting wood can also contribute to a pest infestation – including termites, roaches, mosquitoes, snakes, rats, and so on.

Recommended Crawlspace Humidity Levels

Studies have shown that half of the air in a home comes from either the basement or crawl space. The air contained in your basement or crawl space is often higher in moisture content or humidity and carries with it many allergens and odors. Experts at the Environmental Protection Agency and other sources recommend maintaining a relative basement or crawl space humidity level in the 30%-50% range. Anything above a 50% humidity level for an extended period can cause mold, mildew, and bacteria to grow in your crawl space.
