We Understand How Hard It Is to Worry About Mold in Your Home

Living on Long Island means we get our fair share of beautiful summers—but we also get humidity. And that sticky air you feel in July and August? It’s not just uncomfortable... it can quietly create the perfect storm for mold growth inside your home.


If you've been running your AC nonstop or noticed a musty smell in your basement, attic, or bathrooms, you're not alone. High humidity fuels mold—and once mold starts growing, it doesn’t stop without proper remediation.


Let’s break down how it happens, what to look out for, and most importantly—how we can help.


Why Does Mold Love Humidity?

Mold thrives in environments with humidity levels over 60%. Here’s what that means for homes on Long Island:

  • Warm, humid air enters your home—especially through basements, crawl spaces, and poorly sealed windows.
  • That moisture gets trapped in walls, insulation, or under flooring, creating a damp environment.
  • Mold spores, which are always floating in the air, land and grow—often behind walls or under furniture where you won’t see them right away.


By the time you notice the signs, mold could already be spreading.


Common Signs of Mold in Humid Homes

If you’ve been dealing with persistent humidity, here are some red flags to watch for:

  • Musty or earthy smells, especially in the basement or bathrooms
  • Dark spots or discoloration on walls, ceilings, or vents
  • Peeling paint or bubbling wallpaper
  • Health symptoms like sneezing, itchy eyes, or breathing issues


If this sounds familiar—it’s okay. You’re not alone, and we can help.
