Crawlspace Encapsulation Near You

Transform your musty crawl space into clean, usable storage. Installing a sealed vapor barrier in your home not only keeps your crawl space bright and dry, but helps with radon levels and adds value to your home. Next time you need to check something under the house, you'll be happy you have it.

What is a Crawlspace Encapsulation?

While many homeowners may think a vapor barrier on the floor of a crawlspace constitutes an encapsulation, there’s actually a bit more to it than that. The idea of the crawlspace encapsulation is to seal the crawlspace from the ground as tightly as possible. This entails:

  • Attaching the polyurethane barrier to the foundation walls using masonry anchors, not just tape or caulk, to fasten the barrier to the wall permanently;

  • The polyurethane sheeting is spread out across the floor and sealed to the material attached to the wall using vapor barrier tape;

  • All piers are wrapped with the polyurethane sheeting and sealed to the barrier on the floor using vapor barrier tape;

  • The top edge of the polyurethane barrier is sealed along the top edge of the perimeter using either expanding spray foam or caulk.

  • The polyurethane sheeting should never extend all the way to the sill plate. There should always be a viewing window for pest exterminators to inspect the foundation wall.

Radon Mitigation and Crawlspace Encapsulation

For homes built on a crawlspace foundation the encapsulation is a crucial part of the radon mitigation process. Unlike with slab and basement homes, there’s no concrete barrier in place that contains radon gas as it is coming out of the ground. This requires the installation of a sealed vapor barrier, or encapsulation.

As radon gas is coming out of the ground it needs to first be contained by a vapor barrier so that the other components of the radon system, the fan and the piping, can properly draw the gas outside. The encapsulation works in this way like a concrete slab would, trapping the gas so that a negative pressure can be used to draw it outside before it can enter the home.

What Else is an Encapsulation Good for?

Efficient radon mitigation isn’t the only reason to encapsulate your crawlspace. An encapsulation is also going to help with moisture problems stemming from the crawlspace. Ground moisture can be a big problem in crawlspaces, leading to high humidity, mold growth, pest issues, poor air quality, and nasty odors. The good news is that an encapsulation can block this ground moisture from entering the air and causing these problems.
