Dew point is a critical measurement in moisture control because it tells you when condensation will occur. When surfaces cool below the dew point temperature, moisture from the air condenses into water droplets—leading to mold, wood rot, corrosion, and musty odors. Unlike humidity or temperature alone, dew point provides a more accurate picture of the risk for condensation. That’s why ATMOX systems use dew point calculations to guide fan and dehumidifier operation. With sensors inside and outside the crawl space or attic, the system compares dew point values to determine when ventilation will dry the space—or when it could actually make things worse. This smart use of dew point ensures energy-efficient operation while protecting the structure and indoor air quality. Understanding and monitoring dew point is the foundation of intelligent moisture control and helps homeowners and installers make informed decisions.

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...
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...
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...
Summer heat can be relentless especially in your attic. With attic temperatures soaring up to 150°F in the summer months, your attic can quickly become a hidden threat to your home’s energy efficiency, comfort, and even structural integrity. While it might be out...
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...
In last month's blog, you learned just how essential proper ventilation is to maintaining a home environment that’s both comfortable and healthy. You explored the concept of good air quality in the home and saw how stale air, excess moisture, and lingering...
Moisture control is a crucial aspect of maintaining a healthy crawl space. Excessive moisture can lead to mold growth, wood rot, and even structural damage to your home. In some areas of the US, the dehumidifiers are often being used to reduce excess moisture in a...
Understanding the impact of temperature on air's moisture-holding capacity is a key concept in various fields, including meteorology, agriculture, HVAC systems, residential crawl spaces, attics, and daily comfort. This fundamental relationship, referred to as the...
Moisture issues in the attic are often overlooked yet stem from common household activities that generate significant moisture. As warm air rises from the living space, it carries moisture with it, seeping into the attic through poor sealing and insulation....
Crawl space encapsulation may be one of the most debated and confusing topics within residential building construction. Everywhere you look, you can find another opinion, another study, or another warning. Therefore, a large part of this confusion is that crawl...
