The Benefits of Crawl Space Encapsulation

The Benefits of Crawl Space Encapsulation: Improve the Livability of Your Home


The benefits of encapsulation are dramatic. Relative humidity will stay below 70% even if the outdoor humidity is higher. And if a dehumidification system is installed, humidity can be reduced to less than 50%. Just think: A home with no more rot, rust, mold, odors, insects or other moisture related-problems because of a dank, wet, moisture-laden crawl space.

Crawl space encapsulation is one of the most cost-effective investments you can make in your home. Consider these benefits:

  • Air Quality:  By eliminating excessive moisture, you’ll have better air quality in the crawl space -- and that means better air quality in your home. 
  • Damage prevention: When moisture from the crawl space starts spreading throughout your home, expensive home repairs can lie ahead. Moisture can spread to floor joists, sheathing, roof decks, and siding, causing corrosion, wood rot, and blistered paint. For a home, water is enemy number one and crawl spaces are the prime source of water intrusions and excess moisture build-up.
  • Energy Savings: You’ll save on your utility bills. Energy use studies have found substantial cost savings with a conditioned crawl space with homeowners saving upwards of 20% in energy use. High indoor humidity causes your air conditioner to work harder and less efficiently.  After encapsulation reduces the indoor humidity levels, you’ll see the dollar payback immediately. Your home’s comfort will grow as your energy bills shrink. There is no better win-win scenario for your home and your wallet.
  • Bug and Critter Control: Encapsulated crawl spaces not only keep out moisture, they keep out unwanted critters from taking up residence. Moisture is a welcome mat for destructive insects including ants and termites.
  • Radon Barrier: A vapor barrier can also slow or block most of the movement of radon and other harmful gases found in soil. Higher than national average radon levels are found in many New Jersey counties. According to the NJ DEP, the average indoor radon levels in Monmouth and Middlesex Counties is 2.7 and 2.5 pCi/L, respectively, compared to the average national indoor radon level of 1.3.
  • Home Livability: An encapsulated crawl space improves the livability of your home. Everyone will be more comfortable because of reduced humidity. Crawl space temperatures stay closer to living space temperatures by stopping air movement from the ground, turning your crawl space into a semi-conditioned space. Your floors will feel warmer in the winter and cooler in the summer.
