The adverse health effects of mold contamination are widely known. Fatigue, weakness, headaches, joint stiffness, shortness of breath, sinus congestion or chronic cough are just a few of the ailments associated with mold exposure. The very young, old, pets and people with compromised immune systems are particularly at risk.


Flooding and water damage frequently leave behind an environment that is ideal for mold growth. Infestation can spread quickly so it is essential to deal swiftly and efficiently to combat this threat before it spreads. Despite clever marketing, mold rarely responds to typical home cleaning methods and materials. That’s why it’s important to hire a reliable, accredited company prepared to handle any infestation.


The mold remediation industry is not heavily regulated and many companies perform mold removal without proper training or certification. But hiring such companies may void home warranties or be ineligible for insurance reimbursements. That’s why it’s important to hire a company accredited through the Institute of Inspection Cleaning and Restoration Certification (IICRC). This organization sets the standards for the mold remediation industry across the U.S. and globally.


KOS is IICRC certified (#111805), so you can have peace of mind that all work will be done by trained, knowledgeable professionals with the know-how to provide a lasting solution to your mold problems.

IICRC Certified Mold Remediation Long Island

We Follow A Rigorous Five-Step Process:


  1. Mold testing to determine what type of mold you have and the areas of your home that are affected.
  2. Determine the extent of damage behind drywall and insulation. Mold typically breeds in these areas and this is a critical step to determine the severity of mold infestation.
  3. Safely remove all affected materials in the area of contamination. Since mold spores easily spread when disrupted, we insulate the area and remove any materials that has mold growth, including carpet, drywall, insulation, etc. to prevent the mold from spreading.
  4. Once materials are removed, we treat the entire area with professional strength chemicals to destroy mold and prevent regrowth. The exact method of removal will depend on the type of mold and severity of the infestation.
  5. After all mold has been thoroughly removed and the area is treated, we can return your home to normal. This may involve the use of advanced drying techniques and restoration of cabinets and drywall. At this stage, we’ll do a final inspection to identify and address water or humidity issues before replacing drywall, insulation, and carpet.

Frequently Asked Questions About Mold Remediation on Long Island

  • What are the signs I might need mold remediation in my home?

    If you've noticed a musty odor, visible mold growth, past water damage, or increased allergy-like symptoms when indoors—it's time to call in a professional. 


    Mold can thrive behind walls, in basements, or crawlspaces, often undetected until it becomes a serious problem. At K.O.S. Restoration, we’re trained to locate and eliminate mold at the source.

  • Is mold dangerous to my health?

    Yes—certain mold types, especially black mold, can trigger respiratory issues, headaches, skin irritation, and worsen asthma or allergies. 


    Mold exposure can be especially harmful to children, the elderly, and anyone with compromised immune systems. That’s why our IICRC-certified team takes every case seriously and follows strict remediation protocols.

  • How quickly can you respond to a mold emergency on Long Island?

    We offer 24/7 emergency service and can typically arrive within 45 minutes in Suffolk County. 


    Mold spreads fast—especially after a flood or leak—so immediate containment and drying are crucial. Don’t wait to get help. We’re here when you need us.

  • Do I need to leave my home during the mold remediation process?

    In most cases, our team can isolate the affected area using containment barriers and HEPA filtration so you can safely remain in your home. 


    However, for larger infestations, we may recommend temporary relocation during the most intensive phases of the cleanup for your comfort and safety.

  • Will my homeowner’s insurance cover mold removal?

    It depends on your policy and the cause of the mold. If it resulted from a covered event like a burst pipe or storm damage, insurance may help cover the cost. 


    Our team has experience working with insurance companies and can guide you through the claims process to make things easier.

  • How do you ensure mold doesn’t come back after treatment?

    We don’t just treat the symptoms—we find the source. Our remediation process includes moisture control, HEPA vacuuming, enzyme-based antimicrobial treatment, and in many cases, professional mold encapsulation to prevent future growth. 


    We also educate homeowners on how to reduce moisture and keep their homes safe long-term.
