Sioux City has a mix of new and older homes. Unfortunately, both have issues with crawl space moisture and mold, but typically only older homes have crawl space vents. Old building science thought humid air would flow in and flow out, causing no harm to the crawl space or your home’s structural integrity. This was proven to be incorrect, although homes are no longer built with crawl space vents, plenty still remain in older homes.

Vents allow humid outside air into the crawl space where it becomes trapped and unable to exit. When the air of a different temperature mixes with the original air, condensation happens. This leads to mold, mildew, wood rot, and an overall unpleasant living environment.

We know that half the air we breathe comes from the crawl space, so you’re breathing mold and mildew spores, pest droppings, and humid, musty air if your crawl space is untreated. Groundworks offers several options to seal your crawl space from the outside environment and create dry, usable space.

Where crawl space flooding or moisture issues are prevalent, crawl space drainage can help direct water to a specially designed sump pump. From there it will be pumped out of the crawl space and away from your home. To seal moisture from the rest of your home, a high-quality 20-mil vapor barrier is installed on the walls and floor, locking out moisture and creating a dry, clean space.
