Big Idea: It is important to identify the sources of moisture that can allow mold growth in a home.
- The ideal settings for mold growth include:
- 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.
