Standing water in the basement? Do not step into it if the power is on. If you would have to wade to reach the main switch, do not switch it off yourself. Call an electrician or the power company.Call (844) 817-0274

  • Shut the main water valve if a pipe burst.
  • Photograph and video the damage for the insurer.
  • Move dry valuables upstairs.

  • Use electrical equipment that got wet.
  • Use matches or candles if gas may be present.
  • Touch sewage-contaminated water without protection.

What the official guidance says

  • ElectricityCDC guidance: if you must step into standing water to reach the main switch, call an electrician to turn it off.
  • Wet equipmentElectrical equipment and appliances must be completely dry before they return to service, and a certified electrician should inspect anything in doubt.
  • GasFEMA advises against matches, lighters or candles in a flooded house, because gas may be trapped inside. Use a flashlight.
  • What to discardDrywall and insulation that touched floodwater or sewage should be removed and thrown away.

What a restoration company will do

  1. Confirm the area is electrically safe.
  2. Pump out the water and remove wet contents.
  3. Remove materials that cannot be dried or cleaned.
  4. Dry the structure and record moisture readings.

The EPA's window for drying is 24-48 hours. After that, mold becomes part of the job.
