OCEANSIDE - Some Long Islanders whose homes were flooded during Superstorm Sandy say their insurance company won't pay up over the definition of a word.

Sandy victim Seth Oberstein, of Oceanside, has run into trouble with his Allstate insurance policy. He says the insurance company considers the first level of his home a basement because it’s 2 inches underground. As a result, Allstate says he won't get any money to cover damage to the contents of that level.

Oberstein says he has 10-15 neighbors with similar house designs and similar insurance policies all involved in the legal battle. He says he hopes to settle with Allstate but will sue if it comes to that.

Allstate did not return calls for comment.
