Crawl Space Dehumidifier vs. Crawl Space Encapsulation: Which Is Right for You?

When it comes to protecting your home from moisture-related issues, two popular solutions are crawl space dehumidifiers and crawl space encapsulation. While both options help manage humidity levels, they serve different purposes and offer varying benefits.


A crawl space dehumidifier is a great option for homes dealing with high humidity. It effectively controls moisture levels, reducing the risk of mold growth and improving energy efficiency. However, it does not block outdoor moisture, meaning issues like groundwater intrusion or excessive dampness from external sources may still persist.


On the other hand, crawl space encapsulation is a more comprehensive solution. This method involves sealing the crawl space with a vapor barrier, blocking moisture from entering in the first place. In addition to controlling humidity, encapsulation prevents mold growth, keeps pests and rodents out, and helps improve overall energy efficiency. Unlike a dehumidifier, it also protects homes in areas with high groundwater levels by preventing moisture from seeping in.


For homes experiencing general humidity problems, a dehumidifier may be sufficient. However, if your crawl space is prone to excessive moisture, mold, or pest infestations, full encapsulation is the more effective long-term solution.
