Mold growing within a damp, unsealed crawl space can indeed make you sick, particularly if spores and mycotoxins migrate upward into the main living areas of the house through HVAC ductwork and floor gaps. Exposure to toxic mold can trigger severe allergic reactions, chronic sinus congestion, coughing, skin irritation, headaches, and asthma flare-ups, making professional mold remediation and crawl space encapsulation vital for indoor air quality.
