River silt on basement walls
A mark that tells us how high to read and cut.
The city of Passaic sits right on the river it is named for. When the Passaic River floods, streets and basements here take the water, and the cleanup that follows decides whether mold sets in.
Answering 24/7 from our Johnson St office in Newark
In Passaic, NJ our work follows the Passaic River: flood cleanup after the river overtops, drying and mold removal in basements and ground floors that took river water, and inspections of multi-family buildings where water crossed from unit to unit. We come from our Newark office and treat river water as contaminated from the first call.
During Ida, the Passaic River flooded parts of the city of Passaic, with floodwater about six feet deep in places and 60 residents evacuated to City Hall. Upstream, the NWS flood gauge at Little Falls has a flood stage of 7 feet and has recorded 63 floods since 1903, which tells you how often the river has risen here over the past century.
For homes and apartment buildings in Passaic, that means river water, which is contaminated, is the usual flood source. Porous materials it reaches come out, and walls need reading well above the visible line.
