What are common signs of mold presence in a home?

Visible growth, musty odors, and discoloration on walls are definitive indicators of mold presence in a home. Mold can often be seen as fuzzy patches or spots on surfaces, typically in areas with high moisture levels like bathrooms or kitchens. The distinctive musty odor often accompanies mold growth as it results from the organic compounds released by mold spores. Discoloration on walls, such as dark spots or patches, usually indicates the presence of mold, particularly if the discoloration appears in damp areas.

Other options, while they may suggest certain issues in a home, do not specifically indicate mold presence. Cracked walls and peeling paint may suggest structural issues or problems related to moisture but do not directly denote mold. Excessive dust and pollen are more related to air quality concerns rather than mold specifically. Water stains and uneven floors might indicate water intrusion or structural issues but do not confirm mold presence without visible signs or odors that directly associate with mold growth.
