Crawl Space Encapsulation
The gold standard in crawl space protection. Seal out moisture, mold, and pests with a complete encapsulation system.
What is Crawl Space Encapsulation?
Crawl space encapsulation is a comprehensive moisture control solution that seals your crawl space from the ground and outside air. A heavy-duty vapor barrier (typically 12-20 mil polyethylene) is installed across the entire floor and up the walls, all seams are sealed, vents are closed, and a dehumidifier maintains optimal humidity levels. The result is a clean, dry, conditioned space that protects your home's structure and improves indoor air quality.
Key Benefits
- Eliminates moisture, preventing mold growth and wood rot
- Improves indoor air quality — up to 50% of your home's air comes from the crawl space
- Reduces energy costs by 15-20% by eliminating unconditioned air infiltration
- Protects structural integrity of floor joists, beams, and subfloor
- Prevents pest infestations (termites, moisture ants, rodents)
- Increases home value — encapsulated crawl spaces are a selling point
- Eliminates musty odors in your living space
- Creates usable storage space beneath your home
Our Process
Inspection & Assessment
A certified professional evaluates your crawl space for moisture levels, structural issues, mold, pest damage, and existing drainage. This determines the scope of work needed.
Water Management
Any standing water is addressed first. Drainage systems or sump pumps are installed if needed to manage groundwater before sealing.
Repairs & Remediation
Existing damage is addressed — mold remediation, wood repair, structural support installation, and removal of old, damaged insulation.
Vapor Barrier Installation
A heavy-duty vapor barrier (12-20 mil) is installed across the entire crawl space floor, extending up the walls and around piers. All seams are sealed with specialized tape.
Vent Sealing
All crawl space vents and gaps are sealed to prevent outside air and moisture from entering the space.
Dehumidification
A commercial-grade dehumidifier is installed to maintain humidity below 55%, ensuring long-term moisture control.
Typical Cost
$5,000–$15,000
Factors That Affect Your Cost
- Size of the crawl space (square footage)
- Current condition and needed repairs
- Vapor barrier thickness and quality
- Drainage system requirements
- Dehumidifier size and type
- Local labor rates and accessibility
- Mold remediation needs
