Understanding Common Mold Types in North New Jersey Homes and Businesses and the Importance of Expert Testing

If you live or work in North New Jersey, mold isn’t just a nuisance—it’s a serious health and property risk. With our region’s humid climate, older building stock, and frequent seasonal moisture, mold growth can sneak into basements, attics, HVAC systems, and even behind walls. Whether you're a homeowner in Lincoln Park or managing a commercial space in Paterson, understanding the types of mold you might encounter is the first step toward protecting your space.
