Frequently Asked Questions

High Humidity in Your Crawl Space — Common Questions

What humidity level should my crawl space be at?▼

Ideally, crawl space humidity should be kept between 30% and 50%. Anything above 60% creates conditions for mold growth, wood rot, and pest activity. A commercial-grade dehumidifier with encapsulation helps keep humidity within a controlled range year-round.

Should I close my crawl space vents in Murfreesboro?▼

Yes. In Middle Tennessee's humid climate, open vents actually introduce more moisture than they remove. Sealing vents and conditioning the crawl space with a dehumidifier is the modern, building-science-approved approach to moisture control.

Will a dehumidifier alone fix high crawl space humidity?▼

A dehumidifier helps, but without encapsulation and vent sealing, it works overtime fighting an endless supply of new moisture. Encapsulation seals the space, and the dehumidifier helps maintain drier conditions — together, they form a comprehensive moisture-control system.
