Crawl Space Encapsulation
Protect your home from the ground up

Your crawl space directly affects your home's air quality, structural integrity, and energy efficiency. Up to 50% of the air you breathe on the first floor comes from below—if your crawl space is damp, musty, or moldy, so is the air in your home.
Our encapsulation process completely seals your crawl space from the earth. We install a heavy-duty 20-mil vapor barrier across the entire floor and up the walls, creating a moisture-proof envelope. Seams are overlapped and sealed to prevent any moisture infiltration.
For homes with persistent moisture issues, we can integrate a commercial-grade dehumidifier to maintain optimal humidity levels year-round. The result is a clean, dry space that protects your home and improves indoor air quality.
Signs Your Crawl Space Needs Attention
Warning Signs:
- • Musty odors in your home, especially on the first floor
- • High humidity indoors, foggy windows, or condensation
- • Bouncy or sagging floors indicating moisture damage to joists
- • Increased allergy symptoms from mold spores rising into living space
- • Pest problems - damp crawl spaces attract insects and rodents
- • Standing water or wet soil visible in the crawl space
- • Mold or mildew growth on floor joists or subfloor
Our Encapsulation Process
Inspection & Assessment
We evaluate moisture levels, check for standing water, assess structural components, and identify the sources of moisture intrusion.
Debris Removal & Cleaning
Old vapor barriers, debris, and any contaminated materials are removed. The space is cleaned and prepped for encapsulation.
Drainage Solutions (If Needed)
For crawl spaces with water intrusion, we may install interior drainage, sump pump systems, or exterior waterproofing solutions.
Vapor Barrier Installation
Heavy-duty 20-mil vapor barrier is installed across the floor and up foundation walls. All seams are overlapped and sealed.
Vent Sealing
Foundation vents are sealed to prevent outside air and moisture from entering the conditioned crawl space.
Insulation & Dehumidification
Closed-cell spray foam or rigid foam insulation on walls, plus dehumidifier installation for complete moisture control.
Why Encapsulation vs. Vented Crawl Spaces?
Traditional building practice called for vented crawl spaces, but research now shows this approach actually increases moisture problems in most climates. In Colorado, warm summer air entering through vents condenses on cooler crawl space surfaces, creating the perfect environment for mold growth.
A fully encapsulated crawl space acts as part of your home's conditioned envelope. It stays dry, clean, and maintains consistent temperatures year-round. Energy studies show encapsulated crawl spaces reduce heating and cooling costs by 15-20%.
Key Benefits
Frequently Asked Questions
How much does crawl space encapsulation cost?
Costs typically range from $5,000 to $15,000 depending on crawl space size, condition, and whether drainage solutions are needed. We provide free inspections and detailed quotes.
How long does encapsulation take?
Most crawl space encapsulation projects are completed in 1-3 days depending on size and complexity.
Do I need a dehumidifier?
In most cases, yes. While encapsulation dramatically reduces moisture, a dehumidifier ensures humidity stays below 50% year-round, preventing any chance of mold growth.
Will encapsulation affect my home's foundation?
Encapsulation actually protects your foundation by controlling moisture that causes concrete deterioration. It does not negatively impact the foundation in any way.
