Crawl Space Encapsulation Services
Crawl space encapsulation transforms a damp, vented crawl space into a sealed, clean, and controlled environment. At Schmitt Waterproofing, we install professional encapsulation systems that protect your home from moisture, improve air quality, and increase energy efficiency.
Encapsulation is one of the most effective long-term solutions for crawl space moisture control.
What Is Crawl Space Encapsulation?
Crawl space encapsulation is a comprehensive sealing system that isolates the crawl space from outside air and ground moisture. It typically includes:
- Heavy-duty vapor barrier installation
- Sealing of crawl space vents and penetrations
- Wall and ground liner installation
- Moisture and humidity control
Encapsulation works best when paired with proper crawl space waterproofing.
Our Encapsulation Process
Vapor Barrier Installation
We install reinforced vapor barriers across the crawl space floor and walls to block moisture vapor from the ground.
Vent Sealing & Air Sealing
Exterior vents and gaps are sealed to prevent humid air, pests, and outdoor moisture from entering the crawl space.
Crawl Space Insulation
Wall insulation improves thermal efficiency and helps stabilize indoor temperatures year-round.
Moisture & Humidity Control
Encapsulation systems are often paired with a crawl space dehumidifier to maintain proper humidity levels.
Protect What Matters Most
Benefits of Crawl Space Encapsulation
- Controls moisture and humidity
- Reduces mold and mildew risk
- Improves indoor air quality
- Lowers heating and cooling costs
- Creates a cleaner, usable crawl space
- Helps deter pests and insects
Is Crawl Space Encapsulation Worth It?
For homes with ongoing moisture issues, the answer is yes. Encapsulation provides long-term protection and prevents recurring damage that can impact flooring, framing, and HVAC performance.

FAQs About Crawl Space Encapsulation
Does crawl space encapsulation really work?
Yes. By installing a heavy-duty vapor barrier and sealing off exterior vents, you effectively turn your crawl space into a “conditioned” space. This prevents the “stack effect,” where damp air from the ground rises into your living areas, keeping your home drier and healthier.
How long does crawl space encapsulation last?
A professionally installed system can last 20 years or more. The longevity depends on the quality of the vapor barrier (the “mil” thickness) and ensuring that any drainage issues or plumbing leaks are addressed promptly to protect the liner.
Will encapsulation lower my energy bills?
Most homeowners see a 15% to 20% reduction in heating and cooling costs. Because the air under your home is no longer extreme in temperature (freezing in winter or humid in summer), your HVAC system doesn’t have to work nearly as hard to maintain your indoor climate.
Do I need a dehumidifier if I encapsulate?
In most cases, yes. While the liner blocks ground moisture, a dedicated crawl space dehumidifier manages the humidity levels in the air itself. We typically recommend keeping crawl space humidity below 55% to completely prevent mold growth.
