Sniffing Out Trouble: What That Smell Really Means

If your home has a persistent musty odor, it could be a sign that mold is growing behind walls, under flooring, or even inside your HVAC system. Mold releases compounds known as MVOCS (microbial volatile organic compounds), which often carry an earthy, damp, or stale scent. Mildew, a related fungus that often grows on damp clothing or fabrics, may smell more like rotting wood. Either way, it’s not something you want lingering in your home.

Homeowners often worry about the dreaded black mold (Stachybotrys chartarum), which is linked to serious health issues after prolonged exposure. This mold is known for its distinctive color, making it easier to spot. But in reality, most mold growth in homes comes from more common species like Cladosporium, Penicillium, or Aspergillus. These house molds can cause respiratory irritation and allergies that can lead to disease if left unchecked, especially for those with a weaker immune system.

These types of mold thrive in moisture dense areas such as bathrooms, basements, and in areas that have experienced flooding or water damage. Without removal or proper cleaning, they will continue to spread via airborne spores.
