What Is a Crawl Space Encapsulation?

Crawl Space Encapsulation

Waterproofing your home is essential in ensuring its structure and stability. When waterproofing the foundation of your home, the importance lies in not only sealing the exterior and interior walls but also what is referred to as the crawl space.

What Is Crawl Space Encapsulation?

Did you know that 50% of the air you breathe inside your home rises directly from your basement/crawl space? One of the most effective ways of protecting this area is called crawl space encapsulation. This process differs from what is referred to as “Sealing” which only lines the floor of the space. Full encapsulation covers the floor, walls and even the ceiling in some cases.

The Benefits of Crawl Space Encapsulation

Eliminate Mold & Musty Odors

Common organisms that thrive and colonize in a wet crawl space are mildew and mold. Once they become established, they will start to spread throughout the house and will further promote wood rot. Thus, it will be hard for you to eliminate them.

The special polyethylene barrier which is used for encapsulation will keep out the moisture and the pests and mold that go along with it.

Improves Energy Loss & Efficiency

Back in the day, homes were built with a vent in the crawl space to provide better air circulation throughout the home.  Today, we consider air conditioners to be a necessity and do not rely on these vents.  In fact, if you do have a vent in your crawl space as well as an air conditioner, it could cause more harm than good.  Proper crawl space encapsulation will cut down on energy loss and make your home’s furnace and/or air conditioner more efficient in managing the temperature of your home.

Reduces Dampness & Bugs

By sealing the crawl space area, pests will no longer have easy access to your crawl space and eventually into the rest of your home.  The process of encapsulation will also create a much dryer environment in your crawl space, thus reducing the dampness and ultimately the wood rot and mold that can happen as a result.

Improves Air Quality

Crawl space encapsulation can also increase the air quality throughout the house and eliminate musty odors.  Dehumidification and air purification systems will help to accelerate this process and also reduce energy costs by increasing the efficiency of heating and cooling your home.

Increases Storage

For many homeowners, the crawl space provides a necessary space for storage but only if it is dry and free bugs.

Remember, a healthy basement leads to a healthy home.
