Mold and mildew are two common problems that can grow on the exterior of homes in Nashville, Tennessee. While both are types of fungi that thrive in moist environments, they have distinct characteristics and require different approaches for removal. Understanding the differences between mold vs mildew exterior growth can help homeowners in Nashville take the appropriate steps to protect their homes.
What is Mold?
Mold is a type of fungus that produces spores, which are tiny cells that can float through the air and land on surfaces. When mold spores land on a moist surface, they can begin to grow and spread. Mold often appears as black, green, or brown spots on surfaces and can have a musty odor. Mold can grow on a variety of materials, including wood, brick, and vinyl siding.
What is Mildew?
Mildew is also a type of fungus, but it is generally less harmful than mold. Mildew appears as a white or gray powdery substance on surfaces and does not produce spores. Mildew typically grows on surfaces that are exposed to moisture, such as concrete, brick, and vinyl siding.
Key Differences Between Mold and Mildew
While mold and mildew are both types of fungi, there are some key differences between them:
- Mold produces spores, while mildew does not.
- Mold can be more harmful to human health than mildew.
- Mold often has a musty odor, while mildew does not.
- Mold can grow on a variety of materials, while mildew typically grows on surfaces that are exposed to moisture.
Why is Nashville Prone to Mold and Mildew Growth?
Nashville’s hot, humid summers and mild winters with occasional ice storms create the perfect environment for mold and mildew growth. High humidity levels drive the growth of these fungi on exterior surfaces. Additionally, the pollen season from March to May coats everything in a layer of organic matter that can provide a food source for mold and mildew. The red clay soil in the area can also stain concrete surfaces, creating an ideal breeding ground for these fungi.
The common building materials in Nashville, such as brick, vinyl siding, stone veneer, and hardiplank, are all susceptible to mold and mildew growth. The local vegetation, including southern pine trees, crepe myrtles, and magnolias, can also contribute to the problem by providing organic matter for the fungi to feed on. Heavy algae growth on north-facing roofs due to humidity can also create an environment conducive to mold and mildew growth.
