Mold is a type of fungus that thrives in moist environments. While some molds are harmless, others can produce allergens and toxins that can cause health problems. One of the first signs of a mold problem is a musty or earthy odor. If you notice this odor in your home, it's important to investigate the source of the moisture and take steps to address it.
The moisture level at which mold grows in drywall varies depending on the type of mold and the environmental conditions. Some molds can grow at moisture levels as low as 50%, while others require 85% or higher. However, even if the moisture level is below the threshold for mold growth, it's still important to address any moisture issues, as they can eventually lead to mold growth.
The musty or earthy odor associated with mold is caused by the release of microbial volatile organic compounds (MVOCs). These compounds are produced by mold as it breaks down organic matter. The odor can be more noticeable in areas with high humidity or poor ventilation.
