October 13, 2025

What should I do if my home floods after a storm on Long Island or Queens?


If storm flooding enters your home, turn off electricity (if safe), avoid standing water, and document visible damage. Contact an IICRC-Certified restoration company like K.O.S. Restoration right away. Our team provides 24-hour emergency flood cleanup, water extraction, and drying to prevent mold and structural damage.

Storm Flooding on Long Island & Queens

When powerful storms hit Long Island and Queens, flooding can happen fast. Heavy rain, rising groundwater, and overwhelmed drainage systems can turn basements, crawlspaces, and first floors into disaster zones in a matter of hours.


At K.O.S. Restoration, we understand how devastating it feels to see water pouring into your home. You may be worried about ruined floors, soaked walls, and what comes next — especially when it comes to mold and contamination risks. That’s where we can help.


1. Take These Steps Immediately

If flooding has already started:

  • Stay safe. Avoid entering standing water, especially if power outlets or electrical cords are submerged.
  • Shut off power if it’s safe to do so.
  • Document everything with photos or video for your insurance claim.


Call a professional flood cleanup team — the faster the water is removed, the less damage your home will suffer.

3. Preventing Mold After Flooding

Moisture that remains trapped inside walls, insulation, or flooring can lead to mold growth within 24–48 hours. That’s why immediate drying and dehumidification are essential.

Storm Flooding FAQ'S

  • How quickly should flood water be removed from my home?

    Ideally within 24 hours. The longer water sits, the higher the risk of structural damage, mold, and contamination.

  • Does homeowner’s insurance cover storm flood cleanup?

    Coverage depends on the cause. Standard policies may exclude floodwater from storms unless flood insurance is in place, but water damage from burst pipes or overflows may be covered. K.O.S. Restoration can help document the damage for your adjuster.

  • Can I clean up flood water myself?

    DIY cleanup often misses hidden moisture and contaminants. Professional drying, HEPA filtration, and mold prevention are essential to restore your home safely.

  • How can I protect my home before the next storm?

    Seal foundation cracks, clear gutters, elevate valuables, and install a sump pump or backflow valve. Preventative steps can reduce future damage.
