Crawlspace Encapsulation: Solving Enclosed Moisture Issues in South Carolina



South Carolina is one of the nation’s most prominent areas for housing built on crawlspaces. With water levels so variable, protecting your home from flooding is important when you don’t have the option to build the necessary structure for a basement. However, with our natural moisture levels, crawlspaces are prime territory for mold and mildew, which can rot the structure and foundation of your home.

Encapsulating your crawlspaces is essential for repairing and protecting your home from the natural water content of our humid air. From mold to fungus, Custom Climate is ready to help you understand and repair surface and structural problems with your crawlspace.

Wood is the primary concern in your crawlspace. Because wood has the ability to absorb moisture and is a common material used to construct our homes, it is critical to have your crawl space protected to ensure the longevity and safety of your home.

Do I need Crawlspace Encapsulation?

Cement foundations are not enough protection to your home. The porous makeup of the concrete can still allow for damp air to allow moisture into your home. You may need increased vapor barriers if you experience the following:

  • Bug & Insect Problems
  • Expensive air conditioning costs
  • Humid air or Windows That Accrue Moisture or Sweat
  • Wood flooring that shows evidence of separation, softening, or deterioration
  • Smell or evidence of Mold or Mildew Inside
  • Damp or moist insulation materials


The Solutions


Ventilating your crawlspace is not enough and can even worsen the problem if not done properly. Crawlspace vents – or brick vents – must be installed depending on your building’s coding and the requirements of your space based on square footage, water content, and general condition.

Dehumidifiers may also be a necessary investment for your project depending on the size, scope and current condition of your crawl space. These appliances are critical to managing the humidity of enclosed spaces. If your home has a dehumidifier that is working overtime to keep up with your climate control, it may be because of your crawlspace.

Installing sump systems is another option depending on the environment of your crawlspace. Soil, concrete, wood, and metal all influence the crawlspace because of the difference in their barrier protection to water vapor.

Insulation your flooring may also be necessary to protect moisture from elevating through the crawlspace into your flooring and home. Indoor humidity issues may be a direct result from the moisture-laden air of your crawlspace not being securely separated from the home.
