Crawl Space Repair - Open Vents

The open vents lining the foundation walls of this crawl space are allowing outside air and moisture to influence the area. The idea behind the vents was to let the air outside help ventilate the crawl space and keep it dry. What happens is air and moisture become trapped and add to the increase in relative humidity and allow in pests, critters, snakes, and even water. The odors, allergens, and dust from all this are pulled up into your home resulting in poor indoor air quality.
