Mold Testing and Remediation questions, answered by experts

Several factors affect the color of mold, including humidity levels, age of the mold, and amount of light it receives. A patch of mold that starts out green may darken and turn black as it ages. A species of mold may be green if growing in one environment, but be black in another environment. Color usually isn't a reliable way to determine mold species or risk.

If you’re worried mold might still be lingering after you’ve cleaned your items, here are signs to watch for:

  • Musty smell

  • Visible spots or stains

  • Allergy symptoms when you’re around the item

  • Damp or sticky feel.

If you notice these signs, it might be time to let go of the item or get professional treatment.

Mold is a fungus that typically grows in warm, moist environments, which is why it's so often found in bathrooms, attics, and under sinks. It survives by digesting decaying organic materials, which makes it very helpful for removing dead plant matter around the world. However, if it starts eating away at your drywall, window frames, and flooring, it can harm your home and your health.

The primary signs of mold in an ice machine is a musty odor, slime buildup, and discolored ice. If you notice any of these signs, clean your ice maker immediately.

While the air inside your home should have some moisture—the ideal humidity level is between 30% and 50%—too much moisture can lead to issues. Some ways to tell if there’s too much moisture in your home include condensation inside your windows, mildew growth in the bathroom or mold on surfaces, peeling paint, or an uptick in allergy symptoms.
