Crawl Space Encapsulation in Charleston, SC.

Maintaining a good, safe home starts in the crawl space. While few homeowners brave this space, ensuring your crawl space doesn’t have excess moisture, mold, or mildew can save you hundreds of dollars, plus prevent health issues.

Problems that can occur underneath your home include:

  • Leaking plumbing lines: Plumbing lines can deteriorate over time or be jostled out of place, leading to a leak.
  • Damaged ductwork: Many things can go wrong with AC ducts, from normal wear and tear to rodent infestations to increased condensation.
  • Termite activity: If there’s no barrier blocking them, termites will begin eating through the wooden supports of your home.
  • Rodent nests: Batt roll insulation is commonly used underneath homes, and it makes a great rodent nest.

What is Crawl Space Encapsulation?

Crawl space encapsulation is the process of sealing off your crawl space from the outside environment. This is done by installing a vapor barrier on the floor and walls of the crawl space, as well as insulation and a dehumidifier.

While it’s easy for moisture to collect under your home, it’s just as easy to eliminate the problem with our crawl space encapsulation. This is the most effective and cost-efficient way to seal off your crawl space and prevent future issues from occurring.

Our service includes:

  • Installation of a high-grade liner that’s anchored to the ground and seam-taped together.
  • More liner wrapped around support beams and the foundation walls.
  • Foam boards and spray foam to seal ventilation openings.
  • A dehumidifier to remove moisture from the air.
  • A weather station so you can monitor conditions in your crawl space.

How Moisture Collects in the Crawl Space

Water can come into your crawl space in a variety of ways, such as a water line malfunction, leaking vent wells, cracks in the foundation, and clogged drains. The cause can also be as simple as hot, humid weather. As the warm air rises and passes through the subfloor, the moisture in the air collects inside the insulation, joists, and on the bottom of the subfloor.
