Why do we need a crawl space ventilation fan?

Perpetually enclosed crawl spaces lack essential outdoor air circulation, resulting in the buildup of damp air. This prolonged moisture presence can initiate mold growth and wood decay, weakening its structural integrity. Additionally, damp wood attracts pests like insects and rodents, exacerbating damage through chewing and erosion. Furthermore, airborne mold spores can infiltrate living spaces through floors, gaps, and HVAC systems located in the crawl space, leading to indoor air pollution and potential health risks for your family.
