Crawl space encapsulation is a protective measure that seals off the crawl space with a vapor barrier to prevent moisture from entering the underbelly of your home. By controlling moisture levels, it prevents mold growth, wood rot, pest infestations, and contributes to stable indoor temperatures, saving energy over time. It is a crucial step towards creating a safer, more comfortable, and energy-efficient home.

Do You Need To Encapsulate Your Crawl Space?

  • High Humidity: Crawl space encapsulation insulation controls the moisture level in your crawl space, significantly reducing the risk of high humidity. This control is crucial, as excessive moisture can lead to various structural and health-related issues.

  • Mold Growth: A direct consequence of unchecked humidity is the proliferation of mold. Mold not only damages the structural components of your home, like wooden beams and flooring, but can also severely impact indoor air quality and health.

  • Pest Infestations: Damp environments attract pests such as termites, rodents, and insects, which find crawl spaces ideal for nesting. By sealing these areas with basement crawl space encapsulation, you discourage pest invasions, protecting your home from damage and potential health risks.

  • Poor Insulation: An unencapsulated crawl space can lead to energy inefficiency due to poor insulation. Encapsulation helps maintain a consistent temperature throughout your home, reducing the workload on heating and cooling systems and leading to energy savings.

  • Foundation Problems: Moisture can be particularly detrimental to your home’s foundation. It can lead to the soil expanding and contracting, which in turn can cause foundation cracks and instability. Encapsulation keeps moisture levels in check, safeguarding the foundation’s integrity.

Benefits of Crawl Space Encapsulation

The decision to encapsulate your crawl space brings with it a host of advantages that can significantly improve the comfort, health, and efficiency of your home. Here is a closer look at these benefits:

  • Improved Air Quality: Encapsulated crawl space insulation reduces mold and pollutants, improving indoor air quality.
  • Reduced Energy Costs: Stabilizes temperature for more efficient heating and cooling, lowering utility bills.
  • Structural Protection: Guards against standing water and moisture problems such as rot, mold, and structural damage, prolonging home integrity.
  • Enhanced Home Value: Seen as a valuable upgrade, encapsulation can make your home more appealing to buyers.

How Crawl Space Encapsulation Works

Crawl Space Encapsulation WorksCrawl space encapsulation is a systematic process to eliminate moisture and humidity from the crawl space, thereby preventing the issues they cause. The process involves several key steps:


  • Vapor Barrier Installation: The cornerstone of crawl space encapsulation is installing a heavy-duty vapor barrier along the floor and walls of the crawl space. This barrier is designed to prevent moisture from the ground and exterior from entering the crawl space. It is made from a thick, durable plastic material that covers every surface, including the foundation walls, and is sealed at all seams to ensure no moisture can penetrate.

  • Dehumidifiers: To manage and maintain the humidity levels within the encapsulated crawl space, a dehumidifier is installed. This device continuously monitors the air for excess humidity and removes it, ensuring the space stays dry and moisture-free. The dehumidifier plays a crucial role in maintaining an environment that is hostile to mold, mildew, and other moisture-related issues.

  • Sump Pumps: In areas prone to flooding or where water infiltration is a concern, drainage systems such as sump pumps are installed as part of the encapsulation process. These pumps are placed at the lowest point of the crawl space to collect and prevent any water that manages to enter despite the vapor barrier. This ensures the crawl space remains dry, even during heavy rains or in high water table conditions.

  • Sealing Vents and Gaps: Finally, all vents to the outside and gaps in the crawl space are sealed. This step is crucial to stop the inflow of humid air and pests. It further isolates the crawl space from external conditions, enhancing the overall efficacy of the encapsulation.


By integrating these components, crawl space encapsulation creates a controlled environment under your home that significantly reduces moisture and humidity levels. At NJ Spray Foam Insulation, we have years of experience leveraging state-of-the-art technology and industry-leading practices to ensure your home benefits from the highest level of protection against moisture-related issues.
