What's the Difference Between Mold & Mildew?, Richmond Hill, Georgia

Mold and mildew lead to major problems in homes, including health problems and damage to furniture and walls. Dealing with either can become a constant battle if it’s not tackled quickly and efficiently. While mildew can usually be classified as a household chore, mold removal is a job for professionals. For this reason, it’s important to know the differences between the two.

How Do You Tell Them Apart?

Both are forms of fungi that spread through the spores they produce, which can become airborne. While mold’s detrimental health effects are more severe than those caused by mildew, both can exacerbate breathing problems, such as allergies or asthma. Fatigue, lethargy, fever, and skin rashes are also possible.

Mildew can be white, gray, or yellow in color with a downy or powdery appearance. Meanwhile, mold tends to be black or blue with a fuzzy or slimy appearance.

Another key difference is that mildew remains on the surface of items, whereas mold can bury itself deep into materials, making its removal far more difficult. 

Where Do They Grow?

mold removalMold and mildew both tend to thrive in moist and humid conditions. They’re usually found in bathrooms, kitchens, attics, and basements, as damp areas lacking natural light provide the ideal environment for them to spread.

They usually grow on organic materials such as wood and fabrics, and they’re unlikely to be found on plastics and other synthetic surfaces. Mildew is known for its growth on houseplants and flowers. 

How Should You Deal With Them?

To determine whether you have mold or mildew, dab the substance with bleach for a quick test. If it gets lighter, it’s likely mildew, while if it remains dark, it’s mold. A professional mold tester will be able to verify which fungus you’re dealing with.

An effective way to prevent each from spreading is to ensure good air circulation and reduce humidity levels in your home. According to the EPA, relative humidity should be kept below 60%. Mildew can be tackled using a commercial cleaning product and some vigorous scrubbing. Mold, on the other hand, needs to be dealt with by a professional mold removal company, as it’s too dangerous to be handled by someone without the proper training and equipment.
