The 7 Most Common Types of Mold in New York Homes

Did you know that the mold in your home could be more than just an unsightly nuisance? Some types of mold can pose serious health risks to you and your family. Here’s a guide to the most common molds found in NYC homes—and what you can do to protect your home and health.

Left unchecked, mold can spread quickly, releasing spores that trigger allergies, asthma, and other respiratory issues. In more severe cases, certain types of mold can produce mycotoxins, toxic substances that pose even greater health risks.
