Mold Testing and Remediation questions, answered by experts

Toxic mold doesn't have a specific color; instead, toxicity depends on the type of mold and the mycotoxins it produces. Stachybotrys chartarum (also known as black mold) is notorious for its potential toxicity. However, not all molds appearing black are Stachybotrys chartarum. Mold species that appear in various colors, such as green, gray, brown, or black, can also produce mycotoxins. Therefore, it's essential to focus on identifying the type of mold through professional testing rather than relying solely on color to determine its toxicity.

Mildew is a type of mold that forms in areas of excessive moisture and poor ventilation. Although it commonly exists in household air, it can’t take hold and spread if a surface is clean and dry. Generally, if you have any mildew or mold issues, it’s because the humidity in either your house, room, cabinet, or cupboard is above 50 percent. Common areas where you’ll find mildew are around water sources, which is why it’s commonly found near showers and in kitchen sinks.

The difference between mold and mildew is that mildew is a mild type of mold, whereas mold can be used to describe many different types of fungus. In general, mold is more dangerous than mildew. If you spot mold in your home, you will need a professional mold remediation specialist to help clean and remove it.

It can be challenging to know if mold is growing behind walls without knocking them down. If the walls show signs of water damage (discoloration, water stains, or peeling paint) or there’s a musty odor, it’s possible mold is growing. Know the difference between signs of water damage vs. termites because termite infestations are sometimes mistaken for water damage. A more subtle sign might be your own health: If you’re constantly not feeling well or are sneezing, scratching your eyes, or coughing when in a specific room, you could have mold.

In some cases, black stains on brick are caused by organic substances like algae and mold. However, it's more likely that the black spots you're noticing on your bricks come from carbon from vehicle exhaust or soot. Black stains can usually be removed by scrubbing the brick with a brush and masonry cleaner or power washing.
