(1) Secure the structure to prevent unwanted access.
(2) Contact your insurance company.
(3) Start the recovery process immediately.
Starting the recovery process immediately will minimize collateral damage. In a fire the chemicals contained in the smoke are corrosive to many materials in your home. Water from fire fighting efforts, storms or flooding will continue to cause damage to your home until the drying process begins. The sooner the cleanup and recovery begins the less time and expense it will take to have you back in your home.
