Mold: Sources of Moisture

Big Idea: It is important to identify the sources of moisture that can allow mold growth in a home.

Talking points:

  • The ideal settings for mold growth include:
    • moisture;
    • a surface where mold can grow, such as wet paper products, cardboard, ceiling tiles, and wood; and
    • warm temperatures.
  • There are many common, even everyday sources of moisture in homes, like taking a shower, cooking, and naturally occurring water vapor from soil.
  • Other sources of mold occur when some type of repair or maintenance is needed in the home, including a leaking pipe or roof, clogged gutters, or window condensation.
