The short answer

Stop the Source Safely

Your top priority is stopping more water, fire, or debris from entering your home. If a pipe burst, locate your main water shutoff valve and turn it off. For roof leaks from a storm, place a sturdy bucket or tarp to catch drips, but only if you can reach the area without risk.

If the damage involves electrical hazards, standing water, or structural instability, do not approach. Your safety comes first. Turn off the electricity at the main breaker only if the panel is dry and you can reach it without wading into water. Otherwise, leave the building and wait for a professional.

  • Locate your water shutoff valve now, before an emergency
  • Turn off the main water supply if a pipe has burst
  • Use buckets or tarps to catch active drips from above
  • Avoid standing water near electrical outlets or appliances
  • If you smell gas, leave immediately and call the gas company
  • Do not enter a room with sagging ceilings or warped floors

Protect Your Belongings

Once the immediate source is controlled, focus on saving what you can. Move furniture, rugs, electronics, and important documents to a dry area. Lift items off the floor using blocks or furniture risers. Remove wet fabrics and drapes to prevent staining and mildew.

Take photos and video of everything before you move anything. This visual record helps your insurance company understand the scope of the loss. List each item you relocate, noting its condition. Keep this list with your photos for reference later.

  • Move furniture and boxes to the highest dry spot available
  • Hang wet curtains and rugs outside or on rods to dry
  • Place aluminum foil or wood blocks under furniture legs
  • Remove books and papers from lower shelves
  • Separate wet items from dry ones to prevent further damage
  • Photograph each room before you touch anything

Document Everything

Clear documentation is the right tool during the recovery process. Take wide shots of each affected room, then close-ups of specific damage like water stains, cracked drywall, or lifted flooring. Capture the source of the damage too, such as a broken pipe or a hole in the roof.

Write down the time the damage started, how you noticed it, and what actions you took in the first hour. Note any utilities you shut off. This timeline gives your insurance company and the pros a clear picture of what happened and helps you remember details later.

Call the Right People

After you have secured the scene and documented the damage, contact your insurance company to report the loss. They will tell you what information they need and whether coverage applies. Policies vary, and your insurer decides what is covered. Ask about deadlines for filing a claim and what they expect you to do next.

Then call local water damage pros to begin the drying and restoration work. The sooner they can assess the situation, the better your chances of saving materials like hardwood floors and drywall. Have your photos and notes ready to share with them.

Start Drying Your Home

While you wait for help, you can begin gentle drying efforts if it is safe. Open windows and doors to create cross-ventilation, unless the damage came from a storm that is still blowing rain inside. Turn on fans to circulate air and reduce humidity. Use a dehumidifier if you have one.

Remove standing water with a wet/dry vacuum or mop, but never use a regular vacuum on water. Pull up soaked carpet edges to allow the padding to dry. Do not use heaters in enclosed spaces, as they can warp wood and speed up mold growth in hidden areas. Leave heavy drying equipment to the pros.

Frequently asked questions

Should I turn off my electricity after water damage?

Only if the breaker panel is dry and you can reach it without stepping into water. If there is any risk of shock, leave the power on and exit the home. Call the pros or an electrician to handle it safely.

How do I prevent mold in the first hour?

Start by removing wet items and increasing airflow with fans and open windows. Dry wet surfaces with towels and mops. Mold can begin growing within 24 to 48 hours, so quick action helps, but professional drying equipment is often needed for thorough results.

What should I tell my insurance company right away?

Report the date and time of the damage, the cause, and the areas affected. Share any photos you took and describe what you have done so far. Ask what they need next and whether you should wait for an inspection before making repairs.
