Why Charleston Homes Need Crawl Space Encapsulation

Homeownership in the Holy City presents unique challenges, from humidity to coastal conditions, requiring specialized care to maintain your property.

  • The word humidity is written on a foggy window.

    High Humidity

    Our summers feel like living in a steam room, and that moisture loves to sneak into crawl spaces.

  • A large body of water surrounded by tall grass and trees on a sunny day.

    Coastal Location

    Proximity to the ocean and rivers means constant moisture in the air.

  • A person is holding an umbrella in the rain.

    Heavy Rainfall

    Charleston's frequent rains can lead to water accumulation under your house.

At Crawl Logic Low Country, we've helped numerous Charleston homeowners protect their investments with our state-of-the-art crawl space solutions. These factors can lead to:

  • Mold and mildew growth
  • Wood rot in your home's structure
  • Poor indoor air quality
  • Pest infestations
  • Higher energy bills
  • Structural damage to your home's foundation
Crawl Logic Lowcountry

At Crawl Logic Low Country, we use science to fight dirt and moisture. We keep a close eye on two things:

  • Relative Humidity: This is how much water is in the air. When it's over 70% in your crawl space, trouble starts.
  • Wood Moisture Content: This is how much water is in the wood. If it hits 13%, mold can start to grow. At 19%, you're in the danger zone for big problems.
