Crawl space moisture is a leading cause of mold, structural damage, and poor indoor air quality in homes. Moisture can enter through the soil, gaps and cracks in foundation walls, or leaks, and once inside, it often becomes trapped without proper ventilation or drainage. Excess moisture creates a perfect environment for mold and wood rot, while also attracting pests and creating unhealthy air that can seep into the living space above. The key to controlling crawl space moisture is managing humidity, improving air circulation, and monitoring conditions continuously. ATMOX systems use a combination of fans, sensors, and optional dehumidifiers to control crawl space moisture intelligently. By responding to actual dew point and humidity readings, the system ensures moisture is addressed only when needed—saving energy while protecting your home. Don’t wait until problems become visible. Proactively control crawl space moisture for a healthier, more efficient home.
Can outside air actually help dry a crawl space? The answer is yes, but only when the conditions outside are beneficial to the conditions inside the crawl space. Beneficial outside air is outdoor air that is dry enough, compared with the air in the crawl space, to...
When you look inside a crawl space, some areas can appear dry while others show water droplets, damp insulation or visible condensation on ductwork and pipes. It may look like a leak. In many cases, however, the water is coming from the air itself. A crawl space is...
What causes high crawl space humidity? High crawl space humidity is usually not caused by one isolated problem. It often develops over time and through a combination of water intrusion, moisture evaporating from the ground, humid outdoor air, plumbing or condensate...
This is a hot topic in the crawl space industry. You hear it all the time: encapsulation vs. ventilation. Some people believe the crawl space should be closed up completely. Others believe ventilation is still important. The conversation can quickly turn into an “us...

Moisture in the crawl space can lead to more than just problems below the home. It can affect the air inside the home, the condition of wood materials, and even the flooring above. Since the crawl space is connected to the home, excess moisture underneath should never...
Crawl space moisture can be effectively managed when the right conditions are controlled. Moisture problems typically come from three sources: ground moisture, moisture in the air, and water management issues around the home. Because a crawl space responds to changing...
Crawl space moisture control often begins with a single number: relative humidity (RH). Many homeowners look at a weather app, see high humidity, and assume outdoor air will always increase moisture in a crawl space. Others believe a moderate humidity reading means...
Fall is one of the best times of year for managing moisture in crawl spaces. The hot, humid days of summer are fading, and cooler, drier air is moving in. These milder “shoulder season” conditions make it the perfect time for ventilation to do its job. When outdoor...
Have you noticed some areas in your crawl space remain damp and never seem to dry out, no matter what the weather is like? Maybe it’s just a corner or two that feel musty, or spots where condensation forms more often than others. These areas aren’t just an eyesore -...
Excess moisture often leads to mold in crawl space areas, creating problems that homeowners can’t ignore. When wood, insulation, or other materials stay damp, mold spores have the conditions they need to thrive. This damp environment doesn’t just create musty odors it...
You haven’t seen rain in days or even weeks but your crawl space still feels damp, musty, or humid. If there’s no visible water, what’s causing the moisture? The answers often surprise homeowners: it’s not just about water intrusion. It’s about moisture and...
