Water Damage Restoration in Hoboken, NJ
The biggest flood claim file in Hudson County sits inside one square mile, and more than half of it was written on a single night in 2012. We pump it out, dry the structure, remediate the mold and put the building back — one crew, start to finish.
FEMA holds 2,216 National Flood Insurance Program claims for this city, dates of loss from 1979 to 2026, of which 1,624 were closed with a payment on the building, on contents or on both — $56.5 million in all. That is the largest claim file of the eleven Hudson County communities that have one, ahead of Jersey City and Kearny, and the twenty-second largest of the 654 rated communities in New Jersey. It sits inside a mile square.
One night wrote 1,287 of those rows. Hurricane Sandy is 58.1 percent of everything on this city's file, and the calendar year 2012 holds 1,288 claims against 47 other years between them. Fifty-six New Jersey communities have 1,000 or more claims on record; sort them by the share belonging to that one storm and every community above Hoboken — all twenty of them — is in Ocean, Monmouth, Cape May or Atlantic County, on the ocean. Hoboken is twenty-first, and it is a mile of brownstones on the far side of the Hudson.
What follows is what that file looks like from inside a building rather than from a spreadsheet: which part of a pre-war house here takes the water, what the published warnings actually say about this city and where they are published, and what has to be decided on the day. Everything that is the same everywhere — what to photograph first, how drying is judged finished, when water counts as contaminated, mold, lead and asbestos in older buildings, permits, how a claim works, what belongs in a contract — is on the statewide water damage restoration page, and the county picture around this one is on the Hudson County water page.
What we do
- Water extraction and structural drying — our own crews, not a dispatch network
- Mold remediation — remediation of what the water left behind
- Sewage and flood cleanup — water that came up through a sewer or across the ground
- Rebuild after the damage — the same company puts the building back
- All 21 New Jersey counties — the shop and the crews are in Garfield, Bergen County
- Paid by insurance or by you — we document the loss and the work; we do not handle the claim
Two thirds of what has flooded here was never a finished room
FEMA asks its adjusters to code the lowest level of every building they inspect, on a five-value list: no basement, finished basement or enclosure, unfinished basement, crawlspace, subgrade crawlspace. In Hoboken 1,721 of the 2,216 claims carry that code, and the answer is lopsided. 1,067 are unfinished. 502 are finished. 112 have no basement at all, and 40 are a subgrade crawlspace. The field is blank on the other 495 rows, and those blanks are shown here rather than dropped, because dropping them moves every share on this page.
Two unfinished cellars for every finished one is not what the same field says about most New Jersey towns, and in a city built largely before the Second World War it is not surprising. What sits below a Hoboken brownstone or a pre-war walk-up is usually a low, rough-floored, partly-below-grade space with a boiler, a water heater, the electrical panel, the laundry, the bicycles and whatever the building has accumulated. It is not carpeted. Nobody sleeps in it.
That changes the work in a way worth being plain about, because it cuts both ways. An unfinished cellar has far less to throw away — there is no pad, no base trim, no insulated stud bay holding water eight inches up a wall you cannot see behind. But it holds the things that decide whether the building above it is usable. A soaked boiler and a soaked panel are not dried and switched back on; they are assessed on their own and, more often than not, replaced. Until they are, the building has no heat, no hot water and frequently no power to the lower floors, and none of that is a drying problem.
The second thing an unfinished cellar has is masonry. Old stone and brick foundation walls, a slab or sometimes bare floor, joists and subfloor overhead. Masonry that has been wet gives its water up slowly and keeps giving it up into the air of the space for weeks after the surface feels dry, which is why the finish point is a meter reading that has stopped moving rather than a day on a calendar. The ceiling above it — the underside of somebody's ground-floor apartment — is the part that gets forgotten and the part that grows things.
- The mechanical plant is on the cellar floor in most buildings here, and submerged equipment is judged on its own rather than dried and restarted.
- Masonry releases moisture into the space for weeks after it reads dry to the hand.
- The joist bay over an unfinished cellar is the assembly people forget, and it is somebody's floor.
The only published sentences about water in this city are on New York gauges
There is no river gauge anywhere in this county, and the county page above this one sets out how that was verified and what it means for lead time. This page adds the part that turns up when you go looking anyway: there are three published sentences describing what a given water level does to Hoboken, and both gauges that carry them are in Richmond County, New York.
BGNN6, the Weather Service's gauge at Bergen Point in the Kill Van Kull, and KILN6 at Great Kills Harbor on Staten Island publish the same five impact statements, measured against mean lower low water rather than against a riverbank. Three of the five name this city. At 8.4 feet: "Flooding begins in Hoboken near the riverfront boardwalk. Minor inundation of a several tracks at the Hoboken Terminals." At 9.3 feet: "Inundation of one to two feet occurs at the Hoboken Terminal and the Hoboken Waterfront." And at 14.6 feet, in a long statement mostly about Staten Island: "Inundation of all of Hoboken east of NJ Transit line with three to sevel feet at Waterfront."
Those are quoted exactly as published, typographical errors included, because a gauge statement paraphrased is a gauge statement invented. And what they are worth is worth saying honestly. Three sentences, two of them about a railway terminal and a boardwalk, one of them about a line across the city drawn at a level five feet above that gauge's own major-flood threshold. Not one of them is about a street, a block or a building anybody lives in.
So the practical reading is this. If you are watching a harbour forecast, the useful thing to know is that a reading which puts water on the boardwalk is already a reading that has the Terminal wet, and there is nothing published between there and the top of the scale that will tell you about your own block. The number you can actually act on is the one you already have — where water went last time, in your building, and how long it took to get there. That history is better evidence about your cellar than any of the three sentences above.

The claim file counts insured LOSSES, not buildings. A building that has flooded four times appears four times; a building with no flood policy never appears at all, and in this county most of them do not have one. The event labels are FEMA's, applied by the adjuster, and 244 rows here carry no label — which is why the storm shares on this page are quoted against the full 2,216 rather than against the labelled subset, where they would all read higher.
Common questions
Our building's cellar floods and the landlord says it is the tenants' problem. Who is actually responsible for drying it?
We cannot answer the legal question and we do not try — that is between the lease, the owner and, if it comes to it, a lawyer. What we can do is remove the argument's factual half, which is usually what is actually in dispute. On a shared-cellar building we establish where the water entered before anything is opened, photograph it, and put in writing which assemblies are wet and how far the moisture has travelled into each one, because "the cellar flooded" and "the joists over the cellar are wet under apartment 1R" are different problems with different owners. We will give that record to whoever asks for it, tenant or owner. Two practical notes for this city in particular: the mechanical plant is usually down there and belongs to the building whatever the lease says about the space, and a wet cellar ceiling is somebody's floor, so it rarely stays one party's problem for long.
