Crawl Space Moisture Control

Control crawl space humidity for greater whole-home health, comfort, and energy efficiency

Did you know half of the air you breathe inside your home comes from the crawl space or basement? Your vented dirt crawl space is affecting your health and comfort and costing you money more than you know. The air inside the crawl space is musty and full of mold spores, mildew, dust mites, and bacteria. Moisture in the crawl space also causes mold growth and dry rot, which damages the structure of your home.

The good news is health, comfort, and structural problems caused by crawl space moisture can be avoided with a complete crawl space dehumidification and encapsulation system from Basement Systems.

  • Signs of high humidity in the crawl space

    Some signs of a moisture problem in the crawl space are obvious, but some damage can be hidden and moisture in the crawl space can also cause problems in the upper levels of the home. Here are a few of the ways crawl space moisture affects a home:

    • Musty odors
    • Mold growth
    • Buckling hardwood floors
    • Damp, smelly carpets
    • Increased heating and cooling bills
    • Decreased life of the roof and shingles
  • Causes of crawl space moisture

    There are several ways water and moisture get into the crawl space:

    • Exposed dirt in the crawl space is damp and as the damp soil dries, the wator vapor moves upward through the crawl space.
    • Groundwater enters the crawl space under the footing, between the footing and the walls, or through cracks in the walls. After the water seeps in, it forms puddles and then slowly evaporates upward into the crawl space.
    • Outside air gets into the crawl space through open vents. Humid air causes moisture problems and cold air can make floors cold. Either way, vents don't help the situation.
    • Plumbing leaks in a dirt crawl space will seep into the dirt, making the dirt wet. As the soil dries, the wator vapor moves upward through the crawl space.

Protecting Your Home & Health Begins with Crawl Space Moisture Control

How crawl space encapsulation and dehumidification work together

Today building scientists recommend that crawl spaces be sealed or “encapsulated” to prevent problems caused by crawl space moisture. The encapsulation process involves completely isolating the crawl space interior from damp exterior conditions.

4-step process for effective crawl space moisture control

Our crawl space contractors can solve most crawl space moisture problems with a simple process that includes waterproofing, encapsulation, and dehumidification.

  1. Fix and prevent water intrusion issues in the crawl space by installing an interior drainage system and sump pump.
  2. Install the CleanSpace vapor barrier over the interior walls and floor to seal out moisture.
  3. Seal foundation vents to prevent humid outside air from entering the crawl space.
  4. Install a crawl space dehumidifier to maintain a proper humidity level in the crawl space to help protect against mold, mildew, and wood rot.
