1) make sure the Public Adjuster you hire has owned and operated a company longer than 5+ years, also make sure the firm is a member of NAPIA - www.napia.com the National Association of Public Insurance Adjusters - and if they are not members, keep looking. NAPIA's Public Adjusters are held to the highest standards in the industry.
2) Make sure the adjuster your using is well versed with flood coverage and has the knowledge about what is covered and what is not. Not every Public Adjuster has worked a flood loss, let alone a hurricane losses like Sandy, especially in New York or New Jersey. United States Adjusters are considered experts in both Hurricane and Flood losses having adjusted thousands of flood and hurricane losses over the years.
Final note: If you only have flood damage but you do NOT have flood insurance we cannot assist you. You will need to contact FEMA at: www.fema.gov or 1-800-621-3362. Our Public Adjusters are only able to work with flood victims that have residential and business flood insurance and for Hurricane victims, a wind damage insurance policy is needed in order to assist homeowners and business owners that suffered wind damage from Hurricane Sandy. Lastly, if your basement was the only area in your home or business that was flooded and you do have flood coverage, our public adjusters will NOT be able to to assist you as the cap on basement flooding is so limited on what the National Flood Insurance Program will pay.
