Section 1: Understanding Mold in Long Beach, New York
FAQ 1: Why are Long Beach, New York homes especially vulnerable to mold?
Buildings in Long Beach, New York are generally old, with older plumbing and building materials. Additionally, the city’s humid climate keeps things wet.

Even a small, undetected leak can become a big problem.

Mold grows in irregular patches and may be black, green, brown, white, or orange. Dirt typically remains flat; it doesn’t stink, and it doesn’t lighten with bleach. You can do a quick test to differentiate between dirt and mold by wiping with a cotton swab and a little bleach. If the spot disappears, it’s likely mold
