A living, lurking threat in Sandy-hit homes: mold 03 Feb 2013 Three months after Superstorm Sandy, mold lurks in once-waterlogged buildings, hiding below subflooring, under foundations, and in door and window frames. Sometimes it mottles walls in plain sight. And it can make dwellers sick, another blow to people still recovering from the October storm that sent the Atlantic surging into homes in New Jersey and New York. Mold is flourishing in homes that never completely dried out, where the owners may have waited to make repairs or could not access the house for weeks because of safety concerns. Other flooded homes remain vacant and unheated.
