Crawl Spaces: Open vs Closed

There are many homes that are built over crawl spaces rather than the usual slab. Having a crawl space can provide homeowners with many benefits. There are two major types of crawl spaces, but which one is better: open or closed?

Crawl Space Problems
While crawl spaces do provide homeowners with benefits like protection from flooding, they can also come with a set of drawbacks. Moisture can become trapped, eventually leading to mold, mildew, and water damage. Any of these side effects of excessive moisture will result in a drastic cut in your home’s quality of air. These conditions also make a perfect environment for many pests to live in, so infestations are common.

Open Crawl Spaces
While flooding and moisture from underneath the dirt floor do affect crawl spaces, humidity is one of the biggest factors. Vented crawl spaces can see levels of up to 80 percent humidity during the warmer weather. Any enclosed area that experiences a humidity level above 60 percent is highly prone to develop mold or mildew.

Closed Crawl Spaces
A closed, or encapsulated, crawl space can also develop mold and mildew if moisture is present since there is no air flow. However, if the crawl space is properly cleaned and insulated, there will be less moisture and overall humidity present in this space. Therefore, choosing to have an encapsulated crawl space can be better for your home’s air quality and improve the chances of avoiding pest infestations.
