What Causes Mold on Floorboards?

Mold on floorboards typically develops due to excess moisture. Common culprits include plumbing leaks, roof leaks, high humidity levels, and poor ventilation. Even a small, persistent drip can create the perfect environment for mold growth. When water seeps into the wood, it compromises the structure and provides nutrients for mold spores to flourish. Ignoring these issues allows mold to spread rapidly, making it harder to treat later.
