The short answer

Ensure Your Personal Safety

Your immediate safety is the top priority after a flood. Never walk into standing water if you suspect electricity could be present, as this poses a serious electrocution hazard. If the flooding is severe or you smell gas, evacuate your home immediately and call for help from a safe location. Wait for professionals to declare the area safe before you consider re-entering.

Wear protective clothing like boots and gloves if you must enter a damp area. Be mindful of slippery surfaces and hidden debris in the murky water. Keep children and pets completely away from the affected zones to prevent accidents. Documenting damage can wait until you are certain there is no ongoing danger to your health.

Stop the Water Source

If the flooding is from a broken pipe inside your home, locate your main water shutoff valve and turn it off. This valve is often found where the main water line enters your house, such as in a basement or crawlspace. If you live in Staten Island, keep your shutoff valve location written down for quick access during an emergency.

For external flooding from storms or sewer backups, you typically cannot stop the water source. In these cases, focus on safety and minimizing damage. Move valuable items to higher ground if it is safe to do so. Contacting local water damage pros becomes critical, as they have the equipment to manage large-scale water intrusion.

  • Locate and turn off your home's main water supply valve.
  • If flooding is from an appliance, turn off its individual water line.
  • For a burst pipe, use a pipe clamp or wrap it with rubber and a clamp as a temporary fix.
  • In a storm event, secure doors and windows with sandbags or towels if time allows.
  • Know where your sewer cleanout is to help a plumber if a backup is suspected.
  • Never attempt to stop water from a compromised electrical source yourself.

Protect Your Belongings and Home

Quick action can save your possessions from further damage. Move furniture, rugs, and electronics to a dry area, like an unaffected room or garage. Prop up wet furniture cushions and place aluminum foil under furniture legs to prevent staining carpets. Remove as much water as you safely can using buckets, mops, or a wet-dry vacuum, but avoid using your household vacuum cleaner.

Ventilation is key to starting the drying process. Open windows and doors if weather permits to circulate air. Use fans to increase airflow, but only if there is no electrical risk from moisture. Remove saturated items like boxes and newspapers that can harbor mold quickly. This initial effort helps slow secondary damage before the pros begin their detailed work.

Contact Your Insurance Provider

Notify your insurance company about the flood as soon as you are safe. They will guide you on the next steps for filing a claim. Take many photos and videos of all damage, including water levels and ruined belongings, before you start any cleanup or removal. This visual evidence is crucial for your claim and should be very thorough.

Keep a detailed list of damaged or destroyed items, noting their age and approximate value if possible. Save receipts for any emergency repairs or supplies you purchase. Policies vary, and your insurer decides what is covered. Do not dispose of major damaged items until an insurance adjuster has had a chance to inspect them.

Call Professional Water Damage Help

Floodwater can contain contaminants and cause hidden structural damage. Professional water damage cleanup involves industrial-grade extraction, drying, and dehumidification to prevent mold.

  • Water damage pros use moisture meters and thermal cameras to find hidden wet areas.
  • They employ powerful extractors, air movers, and dehumidifiers to dry structures correctly.
  • They can advise on what materials can be salvaged and what must be removed.
  • They follow industry standards for drying to help prevent mold growth.

  • Their assessment provides a clear scope of work for you and your insurance.

Frequently asked questions

How long do I have before mold starts to grow?

Mold can begin to grow within 24 to 48 hours in damp conditions. The humid climate in many areas accelerates this process. Prompt water removal and drying are your best defense. If you see or smell mold later, a mold assessment by a qualified professional is the next step.

Can I clean up the flood water myself?

You can remove small amounts of clean water quickly. However, most flood water is contaminated and requires professional cleaning. It can weaken structures and hide in walls. The pros have the right equipment to dry your home thoroughly and safely handle the water.

What if my electrical system got wet?

Do not touch any electrical outlets, panels, or appliances that are wet. Have a qualified electrician inspect your system before you restore power. They will check for shorts and damage to ensure it is safe. Using electricity in a flooded area is extremely dangerous and can cause fires.
