Summarize the following:
The sooner that you get in contact with an insurance agent, the sooner your claim can be processed. Your protection will depend on your coverage, and your insurance agent will be able to get the process started. List all of your damaged property before beginning the cleanup process. Include pictures and video evidence if possible.  Let your claims adjuster know when you are disposing of health hazards, such as contaminated food. It can still be claimed, so they need to know about it. Ask about keeping samples. Sometimes you will need to keep samples of damaged property, such as a piece of rug, for claim purposes. During the cleanup process, keep receipts for all of your supplies and any services that you hire. Even motel bills for nights you can't stay in the house count.

Summary:
Call your insurance agent. Make a list. Keep all of your receipts.
