Moisture, Humidity and Rot and How They Affect Your Living Space

Crawl space humidity has negatively affected homes in areas like North Carolina since homes were first built using a crawl space system. As heat levels rise, the temperature soars under your home. Add in the moisture from the humidity and the area underneath your home begins to develop condensation on wood surfaces, leading to serious problems in your crawl space. These problems can ultimately lead to health issues and the need for expensive repairs to damaged and rotting wood surfaces in your crawl space.

Let’s Break It Down

When warm air enters your crawl space through your home’s foundation vents, it’s cooled, which raises the relative humidity of all the air underneath your home.  The resulting moisture can not only attract pests and rot the wood of your home’s foundation, but it can also cause mold – which begins to thrive at around 70% relative humidity. Once your air quality is compromised, you can begin to experience health issues like eye irritation, worsened allergies, headaches and respiratory problems including asthma. In order to avoid this mold growth and the unwelcome side effects, the area under your home needs to remain constant at approximately 55% relative humidity throughout the year.

Controlling Humidity and the Environment in Your Crawlspace

Fortunately, we can control the humidity level under your home by encapsulating your crawl space. Properly sealing out moisture with a vapor barrier system, sealing foundation vents and entryways and treating the air will prevent rising humidity levels. In extreme cases, we may recommend a dehumidifier to dry out the space.

Taking these steps will create a clean and low-humidity environment that will keep your crawl space dry and odor free, and more importantly keep mold, mildew and pests from invading your home.
