Mold growth in homes can be caused by various factors. High humidity levels, often above 60%, create an environment conducive to mold. Leaking roofs, windows, or pipes can introduce moisture into walls and ceilings, providing a breeding ground for mold. Poor ventilation, particularly in bathrooms and kitchens, can trap moisture and contribute to mold growth. Flooding, whether from natural disasters or plumbing issues, leaves behind damp conditions that foster mold. Condensation on cold surfaces like windows and pipes can also lead to mold formation. Additionally, improper drying of wet clothes indoors can increase indoor humidity and promote mold. Effective mold prevention involves controlling moisture levels and ensuring adequate ventilation.

To prevent mold growth and improve ventilation, use exhaust fans in bathrooms, kitchens, and laundry rooms to remove excess moisture. You’ll also want to ensure there is proper ventilation in crawl spaces, attics, and basements by installing vents or fans. Address plumbing leaks or water infiltration promptly to prevent moisture buildup, and maintain indoor humidity levels below 60% to discourage mold growth. Implementing these preventive measures can help reduce the risk of mold growth and create a healthier indoor environment.
