Common Types of Mold and How to Tell You Have a Mold Issue in Your Home

Would you know some of the more common types of mold that appear in homes? Or, would you know how to tell the signs of a mold infestation? Read on to learn about how you can determine if you likely have mold growing in your house.

3 Common Types of Mold 

The 3 most common mold types that grow in houses include cladosporium, penicillium, and aspergillus. They are distinct in their presentation and where they are found.

  • Cladosporium is a green, black, or brown mold that grows in cool and warm locations and can be found on carpets, fabrics, wood, and in heating and cooling ducts.
  • Penicillium is a fuzzy yellow, blue, or green mold that often can be found in basements or insulation, or under carpets, especially if there has been water damage.
  • Aspergullus is a white, green, or gray with dark spots mold that can have a powdery look to it. It doesn’t require much in the way of ventilation, and it can thrive in basements, fabrics, walls, attics, and on dry food items.

How Mold Presents Itself 

You may not be surprised to learn that mold starts as just a little spot. It can spread out quickly and many people notice it shortly after it appears, as long as it’s not in a location you don’t look often. Though it’s often white, black, or spotted, it can appear as nearly any color and be cottony, velvety, or powdery.

If you do see a spot that suspiciously looks like mold, but you aren’t sure if it’s a stain or bit of dirt, here are some ways you can tell the difference:

  • The spot has an earthy and musty smell to it.
  • There’s cracking, peeling, or warping to the material that you notice the spot on.
  • It’s around a source of moisture, but there’s a lack of light to the affected area.
  • Mold continues growing if you don’t do anything to it, while stains and dirt will not.
  • A drop of bleach will lighten the color of the spot within about a minute.

Remember that large mold infestations usually can be seen or smelled. You want to remedy the problem before you and your loved ones begin to experience health issues that can become severe. This is especially the case if you are sensitive to mold, or you have asthma. It’s a good idea to contact a professional for remediation right away through so that you can get back to having a comfortable, healthy home.
