Why a Jersey City finding is written for the ZIP code, not the city
An inspection is worth paying for here because the answer changes with the address. ZIP code 07302 on the Downtown waterfront has filed 1,097 flood insurance claims and taken about 31.5 million dollars since 1978, while 07307 up in the Heights has filed 8 and taken 44,593 dollars across the entire record. The visit settles which of those two buildings you are standing in, names the route the water took to reach the wall, and hands you a dated document a removal contractor has to bid against instead of invent.
Settle the building's age before you pay for a sample
Weigh how old the building is before you decide what to sample. The median home in 07307 in the Heights went up in 1952 and 44.5 percent of that ZIP predates 1939, while at Newport in 07310 the median is 2005 and only 2.8 percent is prewar. Those two buildings hide water in completely different places, so the meters go behind plaster and along a party wall in one, and to window heads, terrace details and a mechanical riser in the other. Weigh second who has to read the result, because a report going to a management company needs the areas, the cause and the fix set out as separate sections.
Which ZIP code the property reports to
07302 carries 1,097 flood claims and about 31.5 million dollars paid since 1978. 07307 carries 8 claims and 44,593 dollars. The same dark patch means different things in the two.
Whether the building predates the war
In 07307 the median unit dates from 1952 and 44.5 percent predate 1939. At Newport the median is 2005. Plaster on lath and a curtain wall are searched in different places.
Whether a sample would change anything
Guidance from the state is that the finding, the cause and the fix are what a report is for. A spore count on top of visible growth rarely changes what has to be done next.
Not sure a sample would tell you anything?
Describe the patch and say roughly where the property sits on the hill. If a test would change nothing, you will hear that first.
After the report: removal and drying across Jersey City
What Jersey City owners ask before paying for a test
My neighbor two blocks over has never had water. Does that tell me anything about my basement?
Very little in this city. Ground runs from about 156.8 feet at Pershing Field in the Heights down to about 6.2 feet at Exchange Place, two and a half miles apart, and the drainage your block sits in is not the one over the hill. That is why the readings are taken at your address and the report names your corner rather than the city.
Can the company that finds it also be the one that removes it?
Nothing in New Jersey stops that, which is exactly why the Department of Health prints the warning itself: consider using a different company to perform testing as well as remediation, because using the same company may present a conflict of interest and should be avoided. The finding and the removal are kept in separate hands here.
