How K.O.S. Restoration Can Fix Mold Problems

There’s nothing like that first drive out to your Long Island summer home—the breeze, the beaches, and the excitement of the season ahead. But what happens when you unlock the door and notice a musty smell… or worse, visible moldgrowing on walls, ceilings, or wood beams?


Unfortunately, mold in summer homes is all too common, especially after a long winter of vacancy. At K.O.S. Restoration, we get the same panicked calls every May and June: "We just opened the house and found mold everywhere!"


If this sounds familiar, here’s what you need to know—and how our IICRC-certified team can help get your home back to normal fast.


Why Does Mold Grow in Unoccupied Homes?

Mold needs three things to grow: moisture, organic material, and a lack of airflow. And unfortunately, that’s exactly what most summer homes on Long Island provide during the off-season.


Whether your home is in The Hamptons, Montauk, Southold, or The North Fork, here’s why mold might have taken hold:


  • Closed-up spaces with poor ventilation
  • Undetected roof or plumbing leaks
  • Humidity buildup during warm spells
  • No heat or air circulation during damp months


Even without visible water damage, mold can grow on walls, wood trim, sheetrock, ceilings, and furniture after just a few weeks of unchecked humidity.


The Health Risks of Mold Exposure

Even if the mold isn’t black, it can still affect your health—especially for children, older adults, or anyone with allergies or asthma. Breathing in airborne mold spores can cause:


  • Sneezing and coughing
  • Eye, nose, and throat irritation
  • Headaches and fatigue
  • Respiratory infections


We understand how upsetting it is to come back to a home you love, only to find it’s not safe to stay in. That’s where we come in.

K.O.S. Restoration offers expert summer home mold remediation services on Long Island.
