Flood Restoration Category 2 Water Loss

WARNING: There are significant health risks as well as a high chance of injury associated with the water damage restoration process. There are also additional health risks, including severe illness and death, associated with improperly drying the structure, as there is the potential for toxic mold to be left behind as well as structural instability.


Jon-Don strongly recommends hiring a trained and certified professional to perform all water damage restoration work.


The following information is intended for use as general guidelines for Category 2 water loss cleanup. No two water losses are alike, and each situation must be treated based on the unique needs of the environment. Before tackling any water loss it is recommended that professionals attend an IICRC WRT Class, an IICRC ASD Class, and be familiar with the industry's standards of care (IICRC S500 and S520) 


A Category 2 water loss refers to a source of water that contains a significant degree of chemical, biological, or physical contaminants and causes discomfort or sickness when exposed or consumed. Known as "Gray Water," this type of water damage carries microorganisms and nutrients of microorganisms. 


Sources of Category 2 water losses include toilet bowls with urine (no feces), sump pump failures, seepage due to hydrostatic failure, and water discharge from dishwashers or washing machines.


Basic Procedure

  1. Complete work contracts.  No work should be started without completed authorizations.
  2. Identify any safety hazards (electrical wires in standing water, loose/buckling drywall, etc.).
  3. Locate the source of the water and stop any further intrusion. It may be required to contact a professional plumber or other contractor. 
  4. Protect furniture by blocking. Small items can be moved out of the affected area.
  5. Extract water from carpet and/or pad by using a sub-surface extraction tool. Remove water from hard surfaces via squeegee or mop. All dehumidifiers should be turned on to give the coils time to reach dew point temperature.
  6. Apply a biocide to all affected surfaces to help prevent and retard the growth of microbials.
  7. Remove and dispose of carpet pad from all affected areas. Remove and discard all non-dryable structural materials.
  8. Inspect all areas that water may have traveled. Document all moisture levels in affected areas.
  9. Create a drying chamber. Remember, you only want to dry the areas that are wet.
  10. Install air movers (approx every 10-15 linear feet). All air movers should be blowing in the same direction.
  11. Monitor the job daily. Record all drying data and keep accurate records.
  12. Dispose of any non-dryable items. Ensure you document and have approval of the homeowner/insurance company before doing so.
  13. Reinstall the carpet with new pad after drying is complete.
  14. Replace all structure materials that were removed.
  15. After drying is complete, all affected areas will need to be cleaned.
