The Homeowner is responsible to take the first steps to minimize any damage to personal property (i.e. remove undamaged items from the area to prevent damages).
Notify your Homeowner or Rental Insurance Agent of the damage as soon as possible to determine if your policy provides coverage for the damage.
Take immediate steps, through your own resources or those of your insurer, to remove excess water or sewage ASAP. Sewage presents special health considerations so you may need professional assistance.
