Crawl Space Encapsulation

Crawl Space Encapsulation Process

At E3 INNOVATE, we take a detailed, step-by-step approach to crawl space encapsulation to ensure your home gets the best possible results:

1. Moisture Control with a Vapor Barrier
   We start by installing a sealed laminate ground cover across the crawl space floor. This vapor barrier prevents moisture from the ground and harmful soil gases like radon from seeping into your home, protecting it and preventing mold growth.  
2. Insulating and Air Sealing the Walls
   Next, we insulate and air seal the crawl space walls using high-performance spray foam insulation. This not only prevents outdoor temperatures and moisture from affecting the crawl space but also creates an airtight seal that blocks air leaks.
3. Sealing and Insulating Ductwork
   If your HVAC ductwork runs through your crawl space, it could be losing energy due to temperature fluctuations. We seal and insulate all ductwork to optimize the efficiency of your heating and cooling systems.
4. Addressing Air Leakage in the Subfloor
   Many contractors stop at the walls and floor, but we go further by addressing air leakage in the subfloor. This ensures that the crawl space is fully encapsulated, prevents pests from entering your living space, contributes to better indoor air quality, and improves energy efficiency.
5. Humidity Control
   Depending on the design of your home and your particular needs, mechanical ventilation and humidity control may be required. We install energy recovery ventilators (ERVs) and dehumidification systems to aid in crawl space (and whole home) health.
6. Radon Mitigation
   Nashville is a ‘Class 1’ radon zone, so E3 includes active radon mitigation in all E3 Sealed Crawlspace Systems to help control radon, odors, moisture.
