How to identify mold and mildew

Do you know the difference between mold and mildew? Most people don’t but there are simple reasons for this common misunderstanding. Mold and mildew can grow in tandem, they start as tiny spores, and they often require a similar environment to flourish.

Since these common substances seem so alike, should you treat them the same? Absolutely not! Mold and mildew have distinct differences in how they appear, significant health consequences, and their abilities to cause property damage.

How Can I Identify Mold vs. Mildew?

It is understandable that the terms “mold” and “mildew” are often used interchangeably. Mildew is actually many different types of fungus, including some types of mold. Both are fungi requiring moisture, oxygen and a food source to thrive, and they can both flourish in many different environments. While mildew is most often seen in shower tile walls and glass doors, it can grow and spread on organic matter, paper, and even cloth.

Mold and mildew each have a distinct appearance, so it is relatively easy to tell them apart.

  • Mold – Look for a soft, fuzzy raised substance, dark green, black, or red in color, with a strong odor.
  • Mildew – Look for a powdery gray, white, or brown substance that appears flat. It also has a foul odor.

Use this handy chart to help you identify mold and mildew around your property:

In the right environment, with plenty of moisture, both mold and mildew can appear in as little as 24-48 hours.

Health Effects of Mold and Mildew

Mold and mildew can create health effects, but they vary somewhat. Mildew is not as invasive and problematic as mild, but over time and prolonged exposure can trigger some respiratory issues, or aggravate those issues in those already suffering from them.

Mold produces allergens that often trigger allergic reactions and can significantly aggravate asthma. It also produces powerful toxins that can irritate the lungs and cause chronic respiratory ailments. Those with preexisting breathing problems can be particularly affected by mold.

How to Prevent Mold and Mildew
The absolute best way to prevent mold and mildew from developing is to control the level of moisture in your home. You should always run a vent fan in areas where steam is prolific, like the bathroom shower. Other areas to keep well ventilated include laundry rooms, the kitchen, and your basement or crawlspace. Aim to keep humidity levels throughout your home between 30-50% for optimum health.

Any leaks should be repaired as soon as they are detected, and a thorough inspection of the area is also wise, to detect if mold or mildew has already begun to grow. Any areas that incur water damage should be dried within 48 hours and closely inspected for mold or mildew. Remove any traces of either immediately to prevent proliferation and spreading.

How to Clean Mold and Mildew

Mildew is more of a surface fungus that can often be cleaned away using detergent, bleach, and a vigorous scrubbing. Always be sure to wear respiratory protection and gloves to prevent health complications from mildew or the cleaning agents.

Mold can be harder to eradicate. Small patches can be removed with a disinfectant or water/bleach solution. Always be sure to wear proper personal protective equipment when addressing areas of mold.

Damp or damaged materials that have or may develop mold are best thrown away in a sealed trash bag. Mold can be present in your HVAC ducts, which could spread it throughout your home. Mold that is allowed to grow can actually penetrate materials, making it impossible to clean without professional remediation.
