What Homeowners Say

We help Charlotte homeowners make crawlspaces clean, dry, and energy-efficient. Here’s a sample of recent feedback:

  • “Worth every penny.” Our floors are warmer and the musty smell is gone in a week. – Danielle P., South End

  • “No more moisture headaches.” Crew was on time, clean, and explained every step. – Marcus R., Ballantyne

  • “Power bill dropped.” After insulation + vapor barrier, our bill fell ~15%. – Leah & Chris, Plaza Midwood

Photos and references available upon request.

Transparent Pricing

Every crawlspace is different. These typical ranges help you ballpark costs before your free inspection:

  • Seal & Stabilize (vapor barrier + basic sealing): $1,200 – $2,500
  • Insulation Upgrade (replace/upgrade insulation, air seal): $2,000 – $4,500
  • Full Encapsulation (20-mil liner, sealing, sump/dehu as needed): $4,000 – $9,500+

Includes inspection, detailed scope, and all labor/materials as quoted. Rebates/financing may be available.

Crawlspace Cost Guide

What drives price?

  1. Size & access: Square footage and tight/low clearance add labor time.
  2. Moisture level: Standing water or high RH may require sump or dehumidifier.
  3. Insulation type: Fiberglass removal vs. new foam/board affects scope.
  4. Vapor barrier: Thickness (10–20 mil), seams, and wall/column wrapping.
  5. Air sealing & ducts: Gaps, rim joists, and leaky ductwork increase load.
  6. Mold or debris: Remediation/disposal adds crew time and PPE.

Quick ballpark formula:
Base $1.50–$3.50 per sq ft for barrier + sealing, then add:
– $1.50–$4.00 per sq ft for insulation removal/replacement
– $900–$2,200 for dehumidifier (if needed)
– $650–$1,500 for sump/pump (if needed)

Your free inspection includes photos, humidity readings, and a clear scope so you know exactly what you’re paying for.
