From combined-sewer backups on the Stapleton waterfront to slope runoff and seepage on the hillside above, we handle flood cleanup to permitted repairs and full rebuild, under one licensed Staten Island contractor.
Anajur Construction Corp. handles water damage for homeowners in Stapleton, Clifton, and Park Hill, the 10304 neighborhoods that run from the Upper Bay waterfront up onto a serpentine hillside. The losses here split by elevation: combined-sewer backups and storm exposure at sea level, slope runoff and foundation seepage on the hill above. We are a NYC DCWP-licensed general contractor (#1220350-DCA) running the full arc from emergency water damage cleanup through permitted reconstruction, as one file, one phone call to Jouri direct at (917) 969-1378.
Stapleton, Clifton, and Park Hill run from the Upper Bay shoreline up onto a serpentine ridge, and that climb is the whole story. The waterfront half and the hillside half take on water for different reasons and file different claims, so averaging them would miss what actually floods a 10304 home.
That range sets 10304 apart from the rest of the borough. The East and South Shores are defined by open-ocean surge; the lowland waterfront here faces the calmer Upper Bay, an old combined sewer, and a high water table, while the graded hillside above sheds its rain downhill onto whatever foundation sits below it. Each of those mechanisms drives a different kind of water damage and a different insurance conversation, so the first thing we do on a loss is establish which one caused it.
Anajur takes a 10304 loss as one continuous job, from the first emergency call to the last coat of paint. We hold our own NYC DCWP general contractor license (HIC #1220350-DCA), so we are not a dry-it-and-leave operation: the crew that pulls water out of a Stapleton basement is the same one that later pulls the permits and rebuilds the room. The sections below break down each loss type on its own page; this one is about how water actually gets into homes across Stapleton, Clifton, and Park Hill.
Ranked by how often they bring us to a 10304 address, across both the waterfront and the hillside. Each one routes to the dedicated service page for the full process. Here is why it happens here.
The older waterfront core in Stapleton and Clifton runs on a combined sewer that carries sewage and stormwater in one pipe. NYC DEP notes a combined system can surcharge on as little as a tenth of an inch of rain; when it does, wastewater backs up through basement floor drains. Routes to sewage cleanup.
Stapleton’s waterfront holds some of the oldest housing on Staten Island, and the mid-century blocks add their own aging supply lines. Galvanized steel and cast-iron plumbing corrodes from the inside until a pinhole becomes a burst behind the wall. Routes to burst pipe water damage and water damage restoration.
Low waterfront lots sit close to the water table, so a sewer surcharge, a failed sump pump, or rising groundwater fills a basement. Routes to basement flooding and sump pump failure.
Above the waterfront, the graded serpentine slopes of Emerson Hill, Concord, and the lower Grymes Hill flank shed stormwater downhill. On cut-and-fill lots that runoff pools against foundations and works through basement walls as seepage. Routes to basement flooding.
The lowest blocks along the Upper Bay and the Narrows carry coastal-flood exposure; Hurricane Sandy pushed surge up those streets in 2012. It is dramatic but rare next to the routine drivers above. Routes to flood cleanup.
Stapleton was laid out in the 1830s on land that had belonged to the Vanderbilt family, and pre-Civil-War homes still stand on Van Duzer Street, where a pair built in 1835 are listed on the National Register. The St. Paul’s Avenue–Stapleton Heights Historic District, designated by the NYC Landmarks Preservation Commission, concentrates more of that late-19th-century stock. In Clifton the mix runs bimodal: roughly a fifth of homes predate 1940 and close to half predate 1980, with 1980s and 2000s infill filling in the rest.
Old stock carries a specific water-damage exposure. Homes of that era were plumbed with galvanized steel supply lines and cast-iron drains that corrode from the inside over decades, so by the time a pinhole becomes a burst, the failure is often behind original plaster where it goes unseen until the ceiling below stains. The age brings a second wrinkle: any Staten Island building constructed under plans filed on or before April 1, 1987 triggers asbestos certification before cavity demolition under NYC Admin Code §28-106.1. Anajur handles the ACP-5/ACP-7 step before opening a wall, rather than discovering it mid-claim.
Stapleton and Clifton also carry dense multifamily housing: the Stapleton Houses, six buildings completed in 1962, and the Park Hill Apartments, about 1,100 units across eight 1960s buildings in the Clifton section. At that density a single roof, riser, or sewer-backup event reaches many units at once, which turns a routine loss into reconstruction-scale work. We carry that from extraction through reconstruction. See burst pipe water damage for the plumbing-failure path and reconstruction after water damage for the rebuild.
Two water sources beyond the plumbing: the combined sewer under the lowland streets, and the Upper Bay at the foot of them.
The combined sewer. Staten Island is mostly a separate-sewer borough, but the old waterfront core is the exception: in Stapleton, Clifton, and Park Hill, stormwater and wastewater share one set of pipes, which leaves the system prone to overflow in heavy rain. Per NYC DEP, roughly 60% of New York City is combined-sewered, and as little as one-tenth of an inch of rain can push a combined system past capacity; when it surcharges, the overflow has to go somewhere, and in low-lying blocks it backs up through basement floor drains. Under IICRC S500 that surcharge counts as a Category 3, black-water loss, which has to be extracted and the area sanitized before any rebuilding can begin; on a 10304 job it goes to sewage cleanup first and then into reconstruction.
The harbor. During Hurricane Sandy on October 29, 2012, the nearest long-record tide gauge (The Battery, across the Upper Bay) logged a storm tide of roughly 14 feet, the highest in the station’s record, and surge pushed into the lowest Stapleton and Clifton streets. It is worth being precise, because the page should be honest: Sandy’s catastrophic residential losses and the Staten Island fatalities were on the East and South Shores (Midland Beach, Oakwood, Tottenville), not the Upper Bay waterfront, and a gauge reading offshore is not the same as inundation depth on a given block. Here the real, ongoing exposure is the handful of low blocks closest to the water, and coastal flooding of those blocks routes to flood cleanup.

The full mitigation-through-rebuild service for any water loss in 10304, the place to start if you are not sure which category your loss falls under.
Coastal and storm flooding of the low Stapleton and Clifton blocks along the Upper Bay.
Category 3 backups when the waterfront’s combined sewer surcharges in heavy rain.
Flooded basements on low waterfront lots and seepage on the hillside above.
Failed supply lines in Stapleton’s old waterfront stock and the mid-century blocks around it.
Groundwater that comes up through the slab when a sump pump dies or cannot keep pace with a high water table.
Stained and sagging ceilings from an overhead leak, common in the area’s multi-story and multifamily homes.
The permitted rebuild after everything is dry, the half a drying-only company hands off to someone else.
The water-damage companies working Staten Island mostly stop once the structure is dry. They extract, they dehumidify, and then they hand over a list of contractors for the rebuild, which leaves you running two vendors and one insurance claim that has been cut in half down the middle.
Anajur is a NYC DCWP-licensed general contractor (HIC #1220350-DCA, NY DOS #2160072), family-owned on Staten Island since 1997. Because the S500 mitigation and the permitted rebuild are written into one file, the carrier’s desk reviewer reads a single estimate from top to bottom, you call one number the whole way, and one company stays accountable from the first emergency through the closing invoice. Where a loss needs a specialist (a licensed Master Plumber on a pump or backwater valve, or an IICRC S520 specialist where mold clears the EPA’s visible threshold), we coordinate that sub-trade and stay the contractor of record on the rebuild.
For 10304 specifically, that continuity matters on both shores: the waterfront’s old and densely occupied housing, and the hillside’s cut-and-fill foundations, both need demolition and rebuild done with care. Get a free estimate or call Jouri direct at (917) 969-1378.

Read the guide →Because 10304 runs from sea level to a serpentine ridge. The Stapleton, Clifton, and Park Hill waterfront sits low along the Upper Bay, where combined-sewer backups, a high water table, and storm exposure drive most losses. The eastern hillside (Emerson Hill, Concord, and the lower Grymes Hill slope) sheds stormwater downhill onto graded lots, so the same rainstorm shows up as slope runoff and foundation seepage rather than a tidal problem. We establish which profile a loss belongs to first, because it changes both the repair and the insurance claim.
On the low waterfront, they can. The older waterfront core is on a combined sewer that carries sewage and stormwater in one pipe, and NYC DEP notes that as little as a tenth of an inch of rain can overwhelm a combined system. When it surcharges, wastewater backs up through basement floor drains, a Category 3 (black-water) loss under IICRC S500. Worth knowing for the claim: a sewer or drain backup is typically excluded from a standard homeowners policy unless you carry a water-backup endorsement, so many of these are out-of-pocket. That category of loss routes to our sewage cleanup work.
The low blocks closest to the Upper Bay were. During Hurricane Sandy on October 29, 2012, the nearest long-record tide gauge (The Battery, across the harbor) recorded a storm tide of roughly 14 feet, a record for the station, and surge pushed into the lowest Stapleton and Clifton streets. To be accurate: Sandy’s catastrophic residential losses and the Staten Island fatalities were on the East and South Shores (Midland Beach, Oakwood, Tottenville), not the Upper Bay waterfront. Here the exposure is the handful of low blocks nearest the water, and that kind of coastal flooding routes to our flood cleanup work.
Yes, on both sides of the ZIP. On the waterfront, basement flooding usually traces to a combined-sewer backup, a failed or undersized sump pump, or groundwater in a low-lying lot. On the hillside, the more common pattern is stormwater sheeting off graded slopes and foundation seepage through basement walls on cut-and-fill lots. The insurance picture differs too: a backup needs an endorsement, while gradual groundwater seepage is generally uninsurable, which is why hillside seepage is almost always out-of-pocket. We diagnose the mechanism, then carry the job from extraction and drying through any reconstruction the basement needs.
Both, on one license. The usual Staten Island water-damage company only handles the drying and then sends you off to hire a separate contractor for the rebuild. Anajur carries its own NYC DCWP general contractor license (HIC #1220350-DCA), so the S500 mitigation and the permitted reconstruction sit on a single file with a single point of contact, not two vendors and two claim conversations. One call to Jouri, start to finish.
All 13 Staten Island ZIP codes. In 10304 that means Stapleton, the 10304 portions of Clifton and Park Hill, Fox Hills, and the 10304 sides of Emerson Hill, Concord, and the lower Grymes Hill slope. The Grymes Hill summit, the core, and Wagner College sit in 10301 on their own page, and South Beach and Rosebank fall into 10305. Anajur is family-owned on Staten Island and has worked across the borough since 1997.
The low waterfront blocks are. Stapleton’s and Clifton’s Upper Bay shoreline falls within FEMA’s high-risk flood mapping, while the higher hillside ground generally does not. One wrinkle worth knowing: New York City’s flood-insurance rate maps still run off FEMA’s 2007 Effective maps, while the City’s Building Code reflects the 2015 Preliminary maps that FEMA agreed to revise, so a specific block’s official zone is best confirmed with an address lookup at the FEMA Map Service Center or the NYC Flood Hazard Mapper before you rely on it. Flood damage is excluded from homeowners insurance and needs separate NFIP coverage.
