The Importance of Crawlspace Encapsulation

50% of the air in your home comes from your crawlspace.

It’s true, half of the air you’re breathing in your home is rising from the crawlspace beneath your house. Most people are unaware of just how significant it is to the rest of their home, but as it turns out, a moist, moldy crawlspace that is left unsealed can bring allergens, radon, mold and more into your home.

Not convinced that your crawlspace can be a danger?

Let’s pose it as a question. Of the images below, which would you prefer to have under your house? Consider maybe kids or pets running around on the floor, or playing near vents.

It’s likely that you preferred the sealed crawlspace to the unsealed one. Even if you’re not quite convinced that an unsealed crawlspace is harmful, you wouldn’t risk your family’s health for certainty. And that is precisely the point. Encapsulating your crawlspace should not come after your kids develop allergies or you yourself develop a cold. It’s a prevention method to ensure that your family stays healthy for years to come.

When a homeowner finds signs of mold in their home and an inspection shows mold in their crawlspace, it makes sense to remove that mold.

But how do you ensure that the mold does not return?

You eliminate areas of moisture. The most certain way of eliminating moisture is by separating the crawlspace from the earth and keeping out the weather…encapsulation. This will protect your crawlspace and ultimately, protect your home.
