For an encapsulated crawl space, the basic approach is:
Seal + Isolate + Dry + Control Air
Crawl Spaces Are Important
50% of the Air in Your Home is Crawlspace Air
Mike Rowe has publicly discussed doing crawl-space encapsulation, foundation repair, and basement waterproofing work on Dirty Jobs. In a 2024 post, he specifically described crawl-space encapsulation as extremely demanding work and discussed his relationship with Groundworks, a company in the foundation and crawl-space industry
If what you're looking for is the indoor-air-quality principle—that crawl-space air can affect the air in the house—that's an important building-science concept. In a humid climate, an uncontrolled crawl space can contain elevated moisture, musty odors, mold spores, and soil gases. Air movement between the crawl space and living area means controlling the crawl-space environment can be an important part of controlling conditions in the home.
1st Step 👣 Assess and Identify
The first step toward a cleaner, drier, healthier crawlspace is to Assess and Identify the conditions beneath your home. Every crawlspace is different, so proper encapsulation begins with a thorough inspection—not simply installing a vapor barrier.
We inspect for standing water, leaks, foundation seepage, condensation, high humidity, damaged insulation, wood deterioration, mold growth, pests, open vents, and air infiltration. We may also measure humidity and wood-moisture levels to identify hidden moisture concerns.
Foundation walls, rim joists, crawlspace doors, HVAC systems, ductwork, drainage, gutters, and penetrations are also evaluated. Once the conditions are identified, we develop a customized Game Plan. Solutions may include drainage improvements, mold remediation, air sealing, insulation, vapor barriers, and humidity control—addressing the source of crawlspace problems, not simply the symptoms.
2nd Step 👣 Choose the Best Plan
Once we Assess and Identify your crawlspace conditions, the next step is choosing the best encapsulation plan for your home. Our goal is to address moisture, humidity, air infiltration, and other identified concerns with a system designed for long-term protection.
At the heart of our system is the Christian Vapor Barrier, our heavy-duty 125-mil lifetime product designed to provide a durable separation between your home and the ground beneath it. The barrier is installed and sealed as part of a complete crawlspace system based on your home's specific needs.
Your customized Game Plan may also include drainage, mold remediation, sealing vents and penetrations, rim-joist air sealing, insulation, and dehumidification. We help you choose the right combination of solutions—providing dependable protection without adding unnecessary work or expense.
