3 Key Differences Between Mold and Mildew

Is it Mold or Mildew?

You have seen it in the basement before, and it has now reappeared after cleaning. What is it? A remediation expert in Denham Springs, LA, has different tests they can perform to figure out if you have mold damage. However, if you don't want to ask for an assessment, then three identifiable features can help you differentiate between these two fungal cousins.

1. Appearance
2. Color
3. Resilience
   

Appearance

The appearance between mold and mildew growth is often evident. Mildew is typically flat and grows of non-porous surfaces, like tile, making it a nonpenetrating substance. Its cousin, however, loves to invade porous items, growing deep within. Mold also has a more three-dimensional appearance and is often described as fuzzy.

Color

Color can also vary drastically between mildew and mold damage. Mold is often more vibrant and colorful, often appearing in green and yellow. Mildew, on the other hand, is often described as being monochromatic, appearing mostly in greys and whites. However, mildew and mold can both alter their color if they come into contact with other liquids.

Resilience

When it comes to resilience, mold growth reigns supreme. Mildew can often be removed with over-the-counter and readily available cleaners. Mold, however, due to its deep-rooted ways, will usually require deep and invasive cleaning practices. For example, porous items might need to be discarded altogether, and non-porous surfaces will typically have to undergo several rounds of scrubbing. Also, because of how mold develops, drywall might need to be removed as well as the insulation behind it.
While mildew and mold damage might both be considered fungal growths, they are significantly different. Therefore, if you cannot figure out which you are dealing with, you are better off hiring a professional to assess your property. They will look for signs of water damage and probably tests the air quality to determine which fungus you are dealing with.
