Crawl space air is the air beneath a building’s main floor and above the soil or ground. This area is known as the crawl space and is typically accessed through a small door or hatch. Crawl spaces are common in many types of buildings, including houses, commercial buildings, and industrial facilities.
The air in crawl spaces can be of concern due to the potential for moisture, mold, and other contaminants that can accumulate in this enclosed space. Crawl space air can also affect the indoor air quality of the living spaces above, as air from the crawl space can enter the building through cracks and openings in the floor. That’s where our team of experts at Perma-Seal come in. Our team can help solve crawl space humidity and air quality issues.
