One question we get all the time is "Shouldn't my crawl space be vented?" Crawl Space vents don't offer enough airflow to keep your crawl space dry resulting in mold, pests, and critters in your crawl space, falling insulation, and in some cases damage to your floor joists. In your home, you may notice; musty odors, high humidity in the house, cold floors, or high energy bills. Sealing and dehumidifying your crawl space helps improve your home's energy efficiency, indoor air quality, helps prevent mold from re-growing, and protects your home's foundation from wood rot.
