Find and fix moisture sources.
Leaks, condensation and damp materials can contribute to mold growth. Address the water source rather than treating only the visible surface.
Keep damp areas dry.
Use ventilation in bathrooms and other moisture-prone spaces. Dry wet materials promptly and maintain indoor humidity at an appropriate level.
Plan the response to existing damage.
The size of the affected area, materials and water source influence the cleanup approach. Review EPA guidance and discuss the appropriate scope with a qualified professional before disturbing suspect materials.
