They release spores and gases that create that unmistakable, unpleasant scent. Ignoring this smell can lead to serious health risks.

Why Does Old Water Damage Smell Worse?

The progression of the smell is directly linked to microbial growth. Mold and mildew are the main culprits behind the strong odors of old water damage. Research shows that these fungi release mycotoxins. These compounds contribute to the pervasive, unpleasant smell.

Type of Water Damage Common Odors Contributing Factors
New Water Damage Damp, wet cardboard, metallic, slightly chemical, fresh rain Absorption into materials, immediate release of VOCs
Old Water Damage Musty, earthy, moldy, mildewy, stale, sour Mold and mildew growth, bacterial activity, decomposition

The Role of Microbes in Odor Development

Microbial growth is the primary driver of the worsening smell over time. When water isn’t dried and removed promptly, mold and bacteria begin to colonize. These organisms feed on organic materials in your home. Their waste products and metabolic processes release gases. These gases are what we detect as odors.
