What can create odors in wet buildings?

Wet building materials can create odors in buildings primarily due to the growth of microorganisms, such as mold and mildew, which thrive in damp environments. When materials like wood, drywall, or insulation become saturated with moisture, they can serve as ideal substrates for these microbes. As they metabolize the organic compounds in the materials, they produce volatile organic compounds (VOCs) and other byproducts that contribute to unpleasant odors.

Additionally, wet materials can trap moisture, leading to ongoing microbial growth even after the initial water intrusion has been addressed. This persistent microbial activity continues to emit odors over time unless the affected materials are properly dried or replaced. Understanding this relationship is crucial for anyone involved in microbial remediation, as addressing the source of moisture and the resulting wet materials is vital for eliminating odors and preventing further microbial growth.
