Leaks between floors
Stains that trace back to a tub, toilet or radiator in the unit above.
Jersey City mold usually starts in someone else's space. The unit above, the basement below or a shared drain line, which is why tracing the water is half the job here.
Answering 24/7 from our Johnson St office in Newark
In Jersey City, NJ our mold work is mostly in multi-unit buildings: ceiling leaks from upstairs, bathroom mold in apartments, and basement backups on a combined sewer system. We come from our Newark office, trace the water across units, document findings for everyone involved, and remove mold under containment with the line answered 24/7.
Most of Jersey City is served by a combined sewer that carries stormwater and sewage in the same pipes, and its wastewater is piped under the Hackensack River to Newark for treatment by the Passaic Valley Sewerage Commission. That system serves about 1.4 million residents in 48 towns.
When a hard storm overloads it, the lowest drain in a building is where water comes back up. In Jersey City, basement apartments, laundry rooms and storage cages take those backups, and the cleanup is a sewage job, not a simple dry-out.
