These are all signs that moisture has entered your home and could promote mold growth.
Understanding Mold
Mold is a type of fungus that grows in damp and humid environments. It reproduces by releasing tiny spores that can travel through the air. Once these spores land on a surface, they can grow and multiply, causing mold to spread.
There are many different types of mold, and each species has unique characteristics. Some common types of mold include Aspergillus, Stachybotrys, and Penicillium. Mold can appear in various colors, including black, green, white, and brown.
Mold and mildew are often used interchangeably, but they are different. Mildew is a mold that usually grows on white or gray plants. Mold, on the other hand, can grow on a variety of surfaces and can be many different colors.
While mold is not always harmful, some types can produce mycotoxins, harming your health. Exposure to mycotoxins can cause various symptoms, including respiratory problems, headaches, and fatigue.
If you suspect mold in your home, it’s essential to identify the type of mold and take steps to remove it. You can hire a professional mold inspector or use a mold test kit. These kits can help you identify the presence of mold spores in your home and tell you what type of mold is present.
