What Causes Cladosporium Mold Growth?

Fix any leaks promptly. Ensure good ventilation throughout your home. Consider using a dehumidifier in damp areas.
Simple Steps for Mold Prevention

Minor surface mold on wood might be salvageable. However, deep-set mold can compromise the structural integrity of the wood. You need to understand if mold on wood can it be saved or does it need replacing. This decision often depends on the extent of the mold and the type of wood.
