Old waterlines on the walls
Past crests leave marks that tell us how high to read.
In Paterson, the river decides a lot. When the Passaic runs high, basements and streets take water, and the mold that follows is most of what we clean up here.
Answering 24/7 from our Johnson St office in Newark
In Paterson, NJ our work follows the Passaic River: flood cleanup after the river crests, drying and removal in basements that took water, and mold testing when a flooded home is being bought, sold or rented. We come from our Newark office and treat river water as contaminated from the first call.
In a December 2023 storm, the Passaic River crested over 10 feet at Paterson, which the mayor called the highest in recent history, with water in basements and streets and emergencies declared in Paterson and Wayne. Fairfield saw flooding in the same storm.
Upstream, the NWS gauge at Little Falls has a flood stage of 7 feet and has recorded 63 floods since 1903. For Paterson homes near the river, flooding is a pattern rather than a surprise, and old waterlines on basement walls are a common sight when we arrive.

See the jobAfter a crest, we measure the waterline first and read the walls above it, then check behind paneling, under flooring and inside anything stored against the foundation. River water is contaminated, so porous materials it reached come out.
We photograph everything before it moves, which is what insurers and landlords ask for after a flood.
Right away. Mold can start within 24 to 48 hours of water exposure.
Clean-water spills, maybe. River water needs porous materials removed and surfaces disinfected.
Yes, inside the contingency window, with attention to past flooding.
Yes. See the Passaic County page.
