Mold Removal in Tarrytown When the Water Came Up the Drain
Water that comes up through a floor drain in low lying Tarrytown may be sewer backflow, and knowing that before cleanup starts protects both your health and your budget. The Village lists as a vulnerability that rising seas and heavier storm rain may push damaging backflow through its culverts and sewers, and its hazard history records a 2020 wind storm with a sewer back up.

Did it smell like sewage?
Tell us where the water first appeared and what it looked and smelled like. That separates a drying job from a contaminated one in Tarrytown.
Clean line or sewer backflow in a Tarrytown basement
Tarrytown rarely floods from the river in the way the Sound Shore does: the Village has 22 paid flood claims across the whole life of the program and one for Ida, although the NWS recorded 6.97 inches of Ida rain here. So the question in a wet Tarrytown basement is which pipe the water came from. Clean supply water from a burst line is one job. A waste line backflow from beyond a trap is the most contaminated class of water in the trade standard, whatever it looks like, and it is scoped as removal first. If you are in a low part of the village, a backwater valve is worth asking a plumber about. For the Loh Park area the Building Department at 1 Depot Plaza keeps a list of flood damaged properties, which is worth asking about before you buy or rebuild there. Three quarters of village homes predate 1980, so any tear out of painted walls in a pre-1978 house brings lead-safe rules with it.
