A crawl space prevents moisture damage and allows easy access to piping and utility areas by keeping a structure off the ground. A crawl space foundation is less expensive than a basement foundation; it is also preferred when soil conditions don't allow the construction of a slab foundation. Crawl spaces are common in areas with high humidity and areas where water builds up excessively. Avoid foundation damage by keeping a crawl space clean and dry all year long.Continue Reading
Relative humidity is the moisture in the air needed to reach maximum humidity. Relative humidity levels are directly affected by air temperature. Levels of above 70 percent create perfect conditions for mold to grow.
When the air reaches 100 percent humidity, air condenses and dampens all organic material in the crawl space, inviting the growth of toxic mold.
Hygrometers and thermohygrometers monitor levels of humidity. A thermohygrometer also monitors temperature, making it more convenient for crawl spaces.
Dehumidifiers control humidity levels. They can activate automatically when humidity reaches 70 percent. This is particularly useful in areas where temperatures shift drastically from day to night.
Crawl spaces must be well-insulated and have a well-installed vapor barrier. Keep gutters clean, close air vents and seal air leaks to prevent humidity issues.Learn more about Heating & Cooling
