What is Mold?

Mold is a type of fungus that grows in multicellular filaments called hyphae. Unlike other fungi that take on a single-celled form, mold appears as fuzzy or slimy patches that can range in color from black and green to white and orange. Mold thrives in environments with high moisture levels and organic material to feed on, making homes and buildings perfect breeding grounds if conditions are right.

Common sources of mold growth include leaks in roofs, windows, or pipes, areas with high humidity such as bathrooms and basements, and even in HVAC systems. Mold spores, which are invisible to the naked eye, can travel through the air and settle on surfaces, where they begin to grow and spread. Even a small amount of moisture can trigger mold growth, which is why it is essential to address any water damage or humidity issues promptly.

Understanding what mold is and how it develops is the first step in preventing and managing its growth in your home. By keeping an eye on potential problem areas and maintaining a dry, well-ventilated environment, you can reduce the risk of mold becoming a serious health threat.
