Jersey City waterproofing · basement to roof · answered 24/7
Wet basements, leaking walls and roof decks, sealed for good
Water in a building almost never enters where it shows up. We trace it from the roof, the walls or the ground, stop it where it gets in, and give it a planned way out with drains and pumps that keep working through the next storm.

Quick answer
For a wet basement, foundation crack, sewer backup, leaking wall, terrace or flat roof in Jersey City, call (201) 578-5199 at any hour. We waterproof rowhouses, brownstones, frame houses, walk-ups and condo buildings from the basement up, working from an office on Newark Avenue and a head office in Carteret, which is where the name Waterproofing Services Carteret comes from.
Membranes, sealers, pumps and dehumidifiers we install come from makers such as
Waterproofing services from the footing to the parapet
Water comes in from the ground under pressure, through masonry in wind-driven rain, and from the roof down. We handle every one of those paths, so the fix you pay for is the one that actually ends the leak.
Basement & foundation
Wet basements, foundation cracks, old stone walls, crawl spaces and flooded basements.
Every drop that falls on your roof is collected by gutters and leaders, and on most Jersey City houses those leaders empty a few feet from the foundation. That puts the whole roof's worth of water right where the basement wall is weakest.
Slide the controls to see what one storm sends down your leaders. The numbers use plain physics: one inch of rain on 1,000 square feet is about 623 gallons, and water weighs about 8.34 pounds per gallon. That's why underground leader drains and grading the yard away from the house often fix a wet basement for far less than people expect.
If the result surprises you, watch where your leaders discharge in the next heavy rain. Water pooling against the house is worth a call.

A heavy summer storm can drop an inch or more in an hour. Planning figures only; your gutters, leaders and grading decide where it goes.
Jersey City buildings
Every building here takes on water its own way
Jersey City packs nineteenth-century rowhouses on filled ground, frame houses on the Palisades rock, pre-war apartment buildings and glass towers into a few square miles. Each leaks differently, and each needs a different fix.
Brownstones and brick rowhouses
Stone and brick foundations with century-old lime mortar, sunken front areaways, shared party walls and roof decks up top. Water usually finds the mortar joints and the areaway drain first.
Below-grade garages, elevator pits, terraces over living space and amenity decks, handled with managers and boards and documented for the next meeting.
Most of these show up long before a flood. Catch them early and the fix is usually smaller and cheaper.
Water at the floor edge
A wet line where the floor meets the wall after rain is groundwater pushing through the cove joint under pressure.
White powder on walls
Efflorescence is salt left behind as water moves through brick, block or concrete. The wall is passing water even if it looks dry.
Musty smell downstairs
A damp, earthy smell means humidity is high enough for mold and rot, often from a crawl space or slow wall seepage.
Sump pump running nonstop
A pump that never rests, or never runs at all, is close to failing. Most fail during the storm you needed them for.
Gurgling floor drains
Drains that gurgle or smell in heavy rain warn of a sewer backup. A backwater valve stops the next one.
Stains under windows and terraces
Damp plaster below a window, balcony door or roof deck points to failed sealant or flashing above, not a plumbing leak.
How a call becomes a dry building
What happens after you phone us
Step 1
You call, we listen
Tell us where the water shows and when. If it's flooding now, we talk you through staying safe first.
Step 2
We trace the source
Moisture readings, water testing in sections and a look outside at leaders, grading and walls. No guessing.
Step 3
Stop it tonight if needed
During a storm we pump out, clear drains or set temporary protection so the damage stops spreading.
Step 4
Fix it properly
Drains, sump systems, crack injection, masonry or membrane work, with a typical price range before work starts.
Step 5
Show you the work
Photos of what we found and what we did, so you have a record for the building file, buyer or board.

Plan before you call
Typical waterproofing costs, and guides written for owners
A whole-basement interior drain and sump system in Jersey City typically runs $3,900 to $14,800; a single foundation crack injection is usually $485 to $1,180. Ranges, not quotes: access, foundation type and how far water travels move every number. Open the waterproofing cost guide for all 39 services.
Do you answer the phone at night when a basement is flooding?
Yes. (201) 578-5199 is answered 24/7, including holidays. Tell whoever picks up where the water is coming from and how deep it is, and we will talk you through staying safe around the electric panel and appliances while a crew and pump are lined up.
What parts of a building do you waterproof?
All of it: basements and foundations, sump pumps and drains, sewer backup protection, crawl spaces, brick walls, windows, balconies, terraces, roof decks, parapets and flat roofs. Water usually travels between those areas, so we look at the whole path, not just the wet spot.
Is interior or exterior basement waterproofing better for a Jersey City house?
On attached rowhouses the outside of the foundation is often unreachable, so an interior drain and sump is usually the practical fix. Detached houses and new construction can take an exterior membrane. Our interior versus exterior guide walks through the trade-offs.
Can you stop sewer water from backing up into my basement?
In many Jersey City and Hoboken basements a backwater valve on the sewer line is the answer, because the streets share combined sewers that surcharge in heavy rain. We check the plumbing layout and coordinate any permit or plumbing sign-off the job needs.
Which areas outside Jersey City do you cover?
The rest of Hudson County, including Hoboken, Bayonne and Union City, plus nearby towns in Essex, Union, Middlesex and Bergen counties. Our head office is in Carteret, so the Rahway and Woodbridge side is covered from there.
We're a phone-first waterproofing company. Call, describe what you're seeing, and you'll speak with someone who knows basements, walls and roofs, not a script.
