Mold vs. Mildew: What’s the Difference and Why It Matters for Your Home

Mold and mildew are terms often used interchangeably, but they’re not the same thing. While both are types of fungi that thrive in moist environments, they look different, grow in different ways, and have varying effects on your health and home.

Knowing the difference between the two is essential—especially for homeowners in humid regions like South Carolina. Understanding how to identify and treat them can help you avoid costly damage and potential health risks.

In this post, we’ll explore Mold vs. Mildew: What’s the Difference and Why It Matters for Your Home, and how a professional mold treatment can make all the difference.

What Is Mildew?

Mildew is a surface fungus that typically appears white or gray and grows in flat patches. You’ll often find it in damp, warm areas such as bathrooms, kitchens, and basements.

Common signs of mildew:

• Thin, powdery texture
• Gray or white in color
• Grows on tiles, walls, or fabric
• Musty odor

Risks: Mildew is generally less harmful than mold but can still cause minor allergic reactions and irritate the respiratory system if left untreated.

What Is Mold?

Mold is usually darker in color—black, green, or brown—and has a thicker, fuzzier texture. It often penetrates deeper into materials like drywall, wood, or insulation, making it harder to remove.

Common signs of mold:

• Black, green, or brown patches
• Slimy or fuzzy texture
• Grows inside walls, under floors, or in ceilings
• Strong, musty odor

Risks: Mold can cause serious health problems, especially for individuals with allergies, asthma, or weakened immune systems. It’s also known to damage the structural integrity of your home over time.

Key Differences Between Mold and Mildew

Whether it’s a mild mildew buildup or a serious mold infestation, taking action early is the key to protecting your home.
