Mold vs. Mildew: How to Tell the Difference and When to Call for Help
Not all fuzzy growths in your bathroom or basement are the same. While mold and mildew might seem similar at first glance, the truth is—they’re very different in terms of appearance, severity, and the risk they pose to your home and health.
As a trusted provider of mold remediation services in Fullerton, CA, Home Sweet Home Restoration is here to help you understand the key differences between mold and mildew, how to spot each one, and when it’s time to bring in a professional.
What Is Mildew?
Mildew is a surface-level fungus commonly found in damp, humid areas like bathrooms, kitchens, and laundry rooms. It typically grows on non-porous surfaces such as shower tiles, windowsills, and countertops.
How to Identify Mildew:
Flat growth, often appearing powdery or fluffy
Usually white, gray, or yellow in color
Has a musty smell but is not as pungent as mold
Easy to wipe away with basic cleaners
Is Mildew Dangerous?
Mildew is generally not dangerous, but it can be a warning sign of poor ventilation or excessive moisture in your home. Left unchecked, it can evolve into more serious mold issues.
What Is Mold?
Mold is a more aggressive and potentially toxic fungus that can grow deep into walls, insulation, carpets, and ceilings. Unlike mildew, mold can’t be simply wiped away—it often requires professional remediation to remove completely.
How to Identify Mold:
Appears fuzzy or slimy
Colors range from black, green, or blue to brown
Strong, persistent musty odor
Grows on porous surfaces like drywall, wood, and fabric
Can cause staining and material deterioration
Health Risks of Mold Exposure:
Allergies and respiratory issues
Headaches and fatigue
Skin and eye irritation
Worsening asthma symptoms
Long-term exposure can lead to serious health complications
