A Real Homeowner’s Rescue Story

When a homeowner in Setauket, New York discovered extensive water damage under their kitchen sink, panic quickly set in. The plumbing leak had gone unnoticed just long enough to cause serious damage — not just to the kitchen flooring and cabinets, but also to the sub-flooring and even into the basement below.


The water had traveled through the structure of the home, affecting basement ceilingsfurniture, and personal belongings—and worst of all, mold had already started to grow.



At K.O.S. Restoration, we understand how overwhelming this kind of situation can be. That’s why when the homeowner reached out, our IICRC-certified team responded immediately.


Mold remediation at a home in Setauket NY.

Our Immediate Action Plan

Our first step was rapid drying and dehumidification of both the kitchen and basement to stop any further moisture damage. Using professional drying equipment and dehumidifiers, we were able to stabilize the property quickly and prevent additional mold growth from forming in untouched areas.



But the visible mold in the basement was already a threat—and we knew time was critical.


Mold Remediation the Right Way

Our crew quickly contained the affected basement areas and began mold remediation following IICRC standards. This included:


  • HEPA vacuuming of all visible mold spores
  • Spraying and wiping down surfaces where mold was present
  • Thorough cleaning of furniture and personal items to remove mold contamination
  • Protection of unaffected areas to prevent cross-contamination


We treated every surface with care—because we know mold isn’t just unsightly; it can be harmful to your health and damaging to the value of your home.


Mold Encapsulation for Lasting Protection

Once the basement was cleaned and dried, our team performed full mold encapsulation of exposed framing and ceiling joists. We applied professional-grade antimicrobial encapsulant to:


  • Basement floor joists
  • Wall studs
  • Other high-risk structural surfaces


This step provides a long-term protective barrier to keep the mold from returning. It’s one of the many reasons why homeowners across Suffolk County trust K.O.S. Restoration for thorough, professional results.

  • What should I do if I find water damage under my kitchen sink?

    If you discover water damage under your kitchen sink, it's important to act fast. Shut off the water supply, dry the area as best as you can, and call a professional water damage restoration company. 


    Hidden leaks can cause mold growth and structural issues—especially if water seeps into sub-flooring or travels to lower levels like the basement.

  • Can mold grow in my basement after a plumbing leak in the kitchen?

    Yes, water from a plumbing leak can easily travel through flooring and framing, especially if the leak goes unnoticed. 


    This moisture creates the perfect environment for mold to grow in basements and other hidden areas of the home. That’s why immediate drying and professional mold remediation are crucial.

    Our team is trained to restore both the structure and safety of your home.

  • What is mold encapsulation and do I need it after remediation?

    Mold encapsulation is the process of applying a specialized sealant to surfaces like wood framing, joists, and wall studs to prevent mold from returning.


     It’s often recommended after mold remediation in basements or crawl spaces to provide long-term protection, especially in humid areas like Suffolk County.

  • Does homeowners insurance cover water damage and mold cleanup?

    Many homeowners insurance policies cover water damage caused by sudden, accidental plumbing issues, but mold remediation coverage can vary.
