Mold Removal in Guttenberg, Where the Ventilation Fails First
In Guttenberg the question is almost never flooding and almost always air, so the cheapest useful step is usually finding out what the building's ventilation is doing. Of the town's 5,476 housing units, 1,450 date from the 1970s, the largest single decade, and that stock fails mechanically where the prewar walkup next to it fails structurally.

Two sewer permits in a town of 0.193 square miles
Guttenberg is 0.193 square miles, the smallest municipality in this service area, holding 11,754 residents at about 60,900 people per square mile, the densest of the ten. At that density almost nothing is detached and almost nothing is independently ventilated, so a moisture problem in one unit is a shared building problem the day it starts. The drainage arrangement is unusual too. The town has two active combined sewer outfalls on two different permits, one at 77th Street and River Road under the North Bergen Municipal Utilities Authority Woodcliff permit and one at 70th Street and Boulevard East permitted to the town itself, so which office answers a sewer question depends on which end of town you are standing at. Flooding, though, is not the story here. Four paid federal flood claims exist in the entire history of the program, worth about 69,000 dollars in total, and the town's center point sits about 191 feet up on the Palisades ridge, so water inside a Guttenberg building comes from the plumbing, the roof, the envelope or condensation and should be diagnosed that way. The 1970s stock, 1,450 of 5,476 units, fails mechanically rather than structurally: air handling, bathroom extract and a cold surface in July, when the dew point at Newark Liberty holds between about 62 and 64 degrees all day. One more thing before you spend anything. The Department of Health's own booklet says that where a visual inspection shows mold, further testing is not necessary and the money is better spent correcting the moisture and cleaning up.
