Have you noticed a musty odor or mold growth in your crawl space? Often these odors are also noticeable in your living space.
These are signs of high humidity. One way to prevent high relative humidity (RH) is to install a crawl space dehumidifier.
Causes of Excess Moisture in a Crawl Space
Excess crawlspace moisture can be caused by:
- Standing water caused by poor drainage, a leak or condensation on pipes.
- Moisture evaporating directly from the ground.
- Outdoor air coming in through crawl space vents. Relative humidity (RH) is dependent upon the temperature, so RH might be closer to the saturation point indoors at cooler temperatures.
Once the sources of standing water are addressed, you can automatically eliminate excess humidity with an Aprilaire Whole-Home Dehumidifier.
It's Important to Remove Excess Moisture in a Crawl Space
High humidity in your crawl space can damage items you store there, cause structural damage and affect the indoor air quality of your entire home.
Too much humidity can cause:
- Mold and mildew growth: These types of fungi cause a musty smell and ruin items like clothing, furniture, books and more. Mold can also cause wood to rot, resulting in structural damage.
Airborne mold and mildew spores can cause a host of health problems, such as asthma, allergies and sinus infections.
- Rust: The metal on your tools, appliances and other items may rust faster.
"Elevated relative humidity at a surface—70 percent or higher—can lead to problems with mold, corrosion, decay and other moisture related deterioration...An elevated relative humidity in carpet and within fabrics can lead to dust mite infestation and mildew."
-U.S. Environmental Protection Agency
