Mold is a type of fungi that thrives in damp, dark environments where there is organic matter, like wood, to feed on. It can grow just about anywhere but is most commonly found in areas such as bathrooms, kitchens, basements, cabinets, and near pipes or ducting areas. Here are some common causes of mold in a house:

• Persistent Humidity: High humidity levels in the air can cause mold to grow on walls, ceilings, in dark closets, under the kitchen sink, etc. This type of mold is especially common if you live near the ocean or a large body of water and could also be worsened by a lack of ventilation.

• Leaking Pipes in the Home: Leaking pipes can cause moisture to accumulate in walls, floors, and ceilings, creating a prime area for mold to develop.

• A Leaking Roof: A leaking roof can cause water to seep into the walls, floors, and ceilings, creating a prime area for mold to develop.

• A Build-Up of Condensation: Condensation occurs when warm air comes into contact with a cold surface, like an exposed cold water pipe. The water vapor in the air rapidly cools upon contact with the cold surface, condensing into water droplets. This process can be seen by observing a glass of ice water on a hot summer day. Heavy condensation can lead to mold growth in your home.

• Poor Ventilation: Poor ventilation keeps the excess moisture trapped in one room where it settles onto the ceiling, walls, floors, appliances, counters, sinks, and any other surfaces. Mold and mildew need a damp or moist area to grow and thrive. When the home experiences a high level of ongoing humidity, the moisture in the air can seep into the walls, floors, ceilings, and furniture, creating a prime area for mold to develop.

• Water Damage: Water damage around windows or doors to the outside of the house can cause molds to grow.

• Storing Wet Items: Storing wet firewood, watering many plants, and storing many vegetables like potatoes and squash can make a mold problem more likely.

To prevent mold growth, it is important to control moisture levels in your home. This can be done by fixing leaks, using exhaust fans in bathrooms and kitchens, and using a dehumidifier in areas with high humidity.
