Moisture
Whether it's from standing water after a rainstorm or just the dirt floor, evaporating moisture can damage wood and insulation and eventually make its way into your home. Mold in the crawl space and upstairs living areas is a common problem caused by excess moisture.
Pests (and their droppings)
Moisture in the crawl space is a magnet for spiders, mice, rats, snakes, termites and other nasty pests. Because the crawl space is usually left undisturbed, this provides a safe haven for critters looking for a cozy home. What's more, much like our kids, critters don't usually clean up after themselves. Pathogens from rodent droppings ad urine can affect the air quality inside your home.
. Protect your home from mold
When water seeps into your crawl space, the enclosed area becomes a breeding ground for mold. Whether the water comes from a burst pipe in your home or from excess rainfall during a storm, chances are you've had a flooding issue at some point or another. Because there is little airflow to these spaces and they are often not dried properly after leaks and flooding, it doesn't take long for mold to form and take over.
Radon
You can't see or smell radon gas, but it's found in almost all soils. It comes from the natural decay of uranium and it moves up through the ground and into the air above and eventually into your home. Studies have linked radon exposure and lung cancer. In fact, radon is the number one cause of lung cancer among non-smokers, according to the Environmental Protection Agency (EPA).
