Each of your home’s systems play a key role in the overall health of your house. Since they rely on each other, a problem in your crawl space such as water damage will eventually spread to other areas of your home – causing major damage.

What is a Crawl Space?

Sometimes, people may refer to a crawl space as a “cubby hole” closet, or even the attic above the rest of the home. But typical crawl spaces are underneath the home.

Not all homes have a crawl space, but it is a common practice to build houses with this hollow area, usually one to three feet high, underneath. The crawl space elevates the home off the ground, and it is a convenient place for HVAC units, ductwork, plumbing, and electrical wiring.

Crawl spaces generally are “out of sight, out of mind” for homeowners, but they should not be. It is crucial to be aware of what is underneath your living space. Would you feel comfortable knowing there could be nasty conditions like mold growth, standing water, failing support beams, insects, and rodents under your feet?

What is Causing These Issues?


The biggest problem is that most crawl spaces were constructed to be vented. While building code calls for vented crawl spaces for air drying purposes, this is harmful to the home. Because of The Stack Effect, air circulates through your home from top to bottom, like a chimney.

In winter, rising warm air increases pressure at the top of the building, which pushes hot air out at the top and sucks cold air in at the bottom. The reverse occurs in summer, when cool inside air tends to get pushed out at the bottom, which draws hot air in at the top. This ends up creating a comfort problem that feeds on itself, moisture damage, and energy loss. (Source: Pro Remodeler)

As hot and humid air contributes to high levels of moisture and humidity in the crawl space and home, this can lead to sagging, soft, buckling floors above, and result in problems to hardwood floors. Similarly, cold wintertime air that is vented inside will make the above floors feel chilly and overtax your furnace.
