Mold is a type of fungus that feeds on organic materials and reproduces by releasing microscopic spores into the air. In nature, it plays a role in breaking down dead plants and wood. Indoors, however, mold can be destructive, especially when triggered by moisture or leaks. It can grow on almost any surface, including wood, drywall, carpet, wallpaper, and insulation. Often appearing as a white, fuzzy layer (known as mildew), mold thrives in damp, humid environments. Leaky pipes, poor ventilation, and high humidity make perfect conditions for mold to spread. Spores can easily enter a home through open windows, on clothing or shoes, with used furniture, or even by clinging to pets. Once inside, mold can compromise air quality and damage the structure of your home.
