How Crawl Space Encapsulation Works To Control Moisture, Odors, Pests, And Mold

If your home has a crawl space instead of a basement, you may have escaped wet basement problems, but a wet crawl space can be just as bad. Since a crawl space is right under your home, you want it to be as dry as possible, but that's hard to do since water vapor is constantly wafting up through the soil. Crawl space encapsulation is one solution that can help. Here's a look at why it works.

Why Crawl Spaces Are Wet And Humid

Crawl spaces have problems with standing water after a rain when there isn't proper drainage around your home. Your crawl space floods for the same reason a basement floods, and even though a crawl space is sort of like an outdoor area, you still don't want water to accumulate in it because there is reduced ventilation in a crawl space, and that makes it hard for water to dry out. Plus, water is constantly seeping into the crawl space from the soil below even if there is no drainage problem. If your crawl space has a dirt floor, then problems with water vapor and high humidity are even worse.

Why Moisture Is Bad In A Crawl Space

Moisture and high humidity is always a threat to your home when it's a long-term situation. If your crawl space has high humidity, mold can grow and spread into the living space above it. Moisture also attracts bugs, and your crawl space can become a haven for pests. A musty crawl space also has a foul odor that you can smell from inside your home. All these problems can be eliminated by encapsulating your crawl space and keeping it dry.

Why Crawl Space Encapsulation Works

Encapsulating your crawl space involves sealing it with a plastic barrier that keeps moisture from getting inside. The most important step is placing the water vapor barrier on the floor of the crawl space. This blocks moisture from seeping up through the soil. However, encapsulation goes a step further and places the plastic over the walls too. The result is a space that's protected against moisture, but in order to control the climate in the crawl space, the air has to be treated too. While you don't need to heat or cool the space, you do need to provide some ventilation or install a dehumidifier to complete the job properly.

Crawl space encapsulation works because it creates a barrier surrounding the space that's completely dry inside. This means no musty air can filter into your living space above and no moisture can build up and rot the wood in the crawl space or cause mold to grow.
