Mold is one of the most common and harmful indoor contaminants. It thrives in damp areas like bathrooms, basements, and kitchens—but it can also grow hidden behind walls or under floors.

What mold needs to grow:

• Moisture
• Organic material (like wood or drywall)
• Time (growth can begin in just 24–48 hours)

Prevention strategies:

• Fix leaks immediately – Whether it’s a roof, plumbing, or appliance leak, moisture must be stopped at the source.
• Use dehumidifiers – Especially in basements or humid climates, to keep RH in the 40–50% range.
• Ventilate wet areas – Use exhaust fans in bathrooms, kitchens, and laundry rooms.
• Dry wet materials fast – Carpets, drywall, and insulation should be dried or removed within 24–48 hours of water exposure.

By managing moisture, you’re cutting off the fuel that mold needs to grow.
