Mold vs. Mildew: What’s the Difference?

Mold and mildew are similar in that they are both fungi that commonly occur in moist areas of homes. Mildew is commonly thought of as less severe and dangerous than mold. While it is true that mildew is considered an early stage of mold, both require attention and fast action if spotted in your home.

Here, we’ll break down the distinct characteristics of mold and mildew, whether or not they should be treated differently, and what to do if you spot either in your home.

 

The Differences Between Mold and Mildew

Mold includes all species of microscopic fungi, of which there are millions. Mold spores naturally exist in outdoor environments, decomposing fallen leaves, dead trees, and other organic matter. When inside, under the right conditions, the spores can thrive on organic materials and fully form into mold. 

Mildew refers to a certain kind of mold or fungus. It usually develops on shower walls, windowsills, and other places where moisture levels are high. The term mildew is sometimes used in reference to early-stage mold growth or molds that grow flat on surfaces. 

Recognizing the characteristics of mildew can help you identify it from other types of mold.

Appearance

Usually, mold has a thick, slimy look, although some species appear more fuzzy than slimy. Black mold is one of the most common types in homes, but molds can also be green, red, grey, and sometimes white.

Mildew, on the other hand, starts with a more powdery texture and is white or grey in color. As it ages, it tends to turn brown.

Common Locations

Both mold and mildew can develop in moist areas with inadequate ventilation. Common locations include showers, sinks, basements, and windowsills.

Smell

It may be difficult to distinguish between mold and mildew solely by smell. Usually, mold has a pungent, earthy odor, and mildew smells musty and damp. Mold often has a stronger odor than mildew.

Health Risks of Mold vs. Mildew

Mold is often considered more developed and therefore more dangerous to human health than mildew, but mold in any form poses health risks. Individuals exposed to mold may experience allergic reactions or respiratory issues.

How To Treat Mold and Mildew

Mold and mildew should both be treated with the same level of care and attention and by a trained professional. While it may be tempting to clean up the mold or mildew yourself, DIY jobs are often temporary fixes of a larger mold problem in the home. A mold remediation specialist will assess the scene and execute a thorough remediation process, ensuring the mold is eliminated and doesn’t return.
