Crawl space ventilation is essential for maintaining a dry, healthy, and structurally sound home. Without proper airflow, moisture can accumulate under your house, leading to mold growth, wood rot, musty odors, and even pest infestations. Traditional open-vent systems often fail to address humidity effectively—especially in humid climates. That’s why modern solutions, like the ATMOX crawl space ventilation system, use intelligent technology to improve results. These systems monitor temperature, humidity, and dew point, then activate fans only when outside air can improve conditions inside the crawl space. This targeted approach avoids bringing in moist air and maximizes drying potential. Crawl space ventilation works well on its own or as part of a system that includes a dehumidifier. It’s also an excellent solution for homes with encapsulated or sealed crawl spaces that still need air circulation. A well-ventilated crawl space helps improve air quality, protects structural components, and reduces the risk of long-term damage.
Over the past several decades, construction preferences and styles have evolved and changed. In some styles, such as bungalows, minimal traditional and cape cod style homes from the 1920s to 1950s, the layouts stayed mostly within a rectangular frame. Once the ranch...
What should my crawl space humidity be? Sounds like an easy question, but humidity is actually a little tricky and sometimes misleading. Why is that? Most people in the crawl space industry often forget that humidity is rH and that “r” is important to remember. It is...
ATMOX focuses on a dew point comparison – not relative humidity. How do you explain dew point vs humidity?
Crawl space ventilation fans work as an excellent tool to dry a crawl space, BUT it is critically important to use them at the right time. If you’ve been researching crawl spaces before landing on this blog, your head is probably spinning. There are so many, many...
