Describe the patch, the smell, and whether the water came up from below or in from outside. That much usually settles which trade this needs, whether it is small enough to handle yourself, and who should be paying for it.

Three storms, one pattern: reading North Bergen's claim record
North Bergen has 159 paid federal flood insurance claims totaling about 5.3 million dollars, spread across 2011, 2012 and 2021 rather than concentrated in one storm. Its median housing unit was built in 1961, 7,361 of 24,959 units date from 1939 or earlier, and 5,518 units sit in two unit buildings.

North Bergen's six active combined sewer outfalls do not discharge to the Hudson. They sit on the western, Meadowlands side of the township at 91st Street, 69th, 61st, 43rd, 29th and 11th Streets, and empty into Bellman Creek, Cromakill Creek and Penhorn Creek, with treatment by the Passaic Valley Sewerage Commissioners.

What a repeating North Bergen leak tells an assessor
A problem that comes back every year is easier to solve than a one off, which is the useful thing about this township's record. North Bergen has 159 paid flood claims worth about 5.3 million dollars spread across 2011, 2012 and 2021 rather than concentrated in a single catastrophe, and a pattern like that points at a recurring drainage fault somebody can actually fix rather than at bad luck. So the assessment is built around recurrence: where the water enters, what it follows, how wide the wet area really runs, and which repair would end it instead of postponing it.
What to note before a North Bergen assessment is booked
Write down the months, because seasonality is evidence and it costs nothing to collect. Newark Liberty averages 12.5 days a year with an inch or more of precipitation and 81.9 nights below freezing, which is the maintenance calendar for this township: drains and gutters ahead of the wet months, pointing and parapets after the freeze cycle. A wall that darkens after the heavy days points at drainage. One that appears in spring after a hard winter points at a masonry or parapet failure that opened up in the freeze. Bring that history to the visit and the meters have somewhere to start, which shortens the appointment and sharpens the report.
Which months it happens in
About 12.5 heavy rain days and 81.9 freezing nights a year. Which of those your wall tracks is half the diagnosis.
Whether it has happened in more than one year
The township's claims sit in 2011, 2012 and 2021. A repeating fault has a findable path.
Which slope of the township you are on
The back slope drains to the Meadowlands creeks and the ridge does not, so the two sides fail differently.
Same wall, every year?
Send the months and the wall. A repeating fault has a findable path and a fixed price.
What follows a North Bergen assessment
What North Bergen owners ask before booking a test
It happens most years. Is that just what old basements do?
No, and treating it that way is expensive. A claim record spread across 2011, 2012 and 2021 rather than one storm is the signature of a drainage fault, and faults have locations. The assessment follows the water rather than the stain, measures how far the wet area actually runs, and names the repair, which in this township is usually outside the building rather than inside it.
What should I look at after the freeze each winter?
Look up. With about 81.9 nights a year below freezing at the nearest first order weather station, freeze and thaw works on pointing, parapets and roof details all winter, and the leak that shows up in March often opened in January. A look at the masonry and the roof edge after the cold, and the drains cleared before the wet months, prevents more damp than any product sold for it.
Tell us the history, not just today
Which years, which months, which wall. That is what turns a visit into a diagnosis.
