The Causes of Wet Insulation Odor

You’ll notice a distinct smell in wet insulation that can be caused by various factors.

One of the main causes is mold growth. When insulation becomes wet, it creates a damp environment that is ideal for mold to thrive. As the mold grows and spreads, it releases volatile organic compounds (VOCs) into the air, resulting in a musty odor.

Another factor that contributes to the smell of wet insulation is moisture damage. If there are leaks or water seepage in your home, it can lead to damp insulation. The combination of moisture and trapped air within the insulation can create an unpleasant smell.

Identifying the smell of wet insulation will help you take appropriate steps towards addressing the issue without delay.
