Crawl Space Services in Mount Pleasant, SC

We don’t push cookie-cutter systems. Instead, we provide custom crawl space repair, encapsulation, and waterproofing solutions based on your home’s unique needs.

Crawl Space Encapsulation

  • Heavy-duty vapor barrier sealed to walls and floor
  • Seals vents and air leaks to block out coastal humidity
  • Prevents mold, mildew, and wood rot

Local Highlight:

We encapsulated a crawl space in Belle Hall, where moisture and falling insulation had caused indoor air quality issues. Post-encapsulation, the home’s HVAC ran smoother and allergy symptoms disappeared.

Structural Repairs & Floor Joist Support

  • Replacement of rotting beams and sagging floor joists
  • Lifts and stabilizes soft or bouncy floors
  • Especially effective for older Mount Pleasant homes with pier-and-beam construction

Why It Matters in Mount Pleasant:

Homes built in marsh-adjacent areas like Old Village often suffer from long-term moisture exposure that weakens floor supports.

Crawl Space Insulation

  • Closed-cell insulation to resist moisture intrusion
  • Keeps floors more comfortable year-round
  • Reduces HVAC workload and helps with energy efficiency

Drainage Systems & Sump Pumps

  • Interior French drains to handle storm runoff and rising groundwater
  • Sump pumps with battery backup to remove water during extreme weather

Local Highlight:

A homeowner in Seaside Farms experienced seasonal flooding. We installed a French drain and sump pump system — it’s remained dry through two hurricane seasons.
