What Electronic Leak Detection Includes
Every detection call covers the full diagnostic sweep and a written summary of what we found. Repair work is quoted separately once the leak is located, so you are never paying for demolition before you know the problem.
- Full Pressure TestWe isolate and pressurize the domestic water line with pressure testing gauges to confirm whether the leak is on the supply side. This step rules out drains, irrigation, and fixtures before we go further.
- Acoustic SweepAcoustic listening devices trace the sound of escaping water across the slab. We sweep the full floor area, not just the room you called about, because leaks travel along the pipe path.
- Thermal Imaging ScanA Flir thermal camera maps temperature differences under the floor. Hot-water leaks show as warm stripes; cold-line leaks show as cool spots. We compare the image against the acoustic reading.
- Pinpoint MarkingWe tape the exact leak location on your floor and confirm depth with pipe locators. You see the spot before anyone cuts. Most marks land within a few inches of the actual break.
- Written FindingsYou get a summary of what we tested, what we found, and the repair options with pricing. It is yours to keep, and it is written plainly enough to hand to an insurance adjuster if needed.
Electronic Leak Detection for Homes
We test your supply line, sweep the floor with acoustic and thermal gear, and mark the leak before any concrete comes up. You get the findings in writing the same visit.
- Warm spot on the floor
- Water bill spike

Electronic Leak Detection Kearny NJ: How It Works
Electronic Leak Detection Kearny NJ is a non-invasive diagnostic service that locates hidden water leaks using acoustic listening devices, thermal imaging cameras, and pressure testing gauges. We pressurize the line, listen for the escape point, and map the temperature difference the leak creates under the slab. Instead of breaking concrete on a guess, we mark the exact spot on the floor and only open what we have to. Most inspections take two to four hours from arrival to written findings.
Kearny homes built before 1970 usually still run copper pipes under the slab, and copper corrodes where soil shifting and road salt have worked the line loose. That is why we get so many calls from the 07032 ZIP code after a cold snap. If you are searching for digital leak detection near me Kearny, we can usually be on site the same day, confirm the leak, and tell you whether it is a repair or a reroute before we leave.
We listen, we scan, we mark the spot before anyone cuts concrete.
What to Expect During Detection
Five steps, no surprises. Here is exactly how a call-out runs from the moment we pull up to the moment we hand you the findings.
Arrival and Interview
We ask what you have noticed: warm spots, a spike on the bill, the sound of running water at night. That history tells us which line to test first. Takes about ten minutes and saves an hour of searching.
System Pressure Test
We isolate the domestic water line and pressurize it with pressure testing gauges. If the gauge drops with every fixture closed, the leak is confirmed on the supply side. This is the step that separates a real slab leak from a drain issue.
Acoustic and Thermal Sweep
Acoustic listening devices pick up the hiss of water escaping under pressure. Thermal imaging cameras show the warm stripe a hot-water line leaves in the slab. We sweep the whole floor and compare both readings before we commit to a location.
Pinpoint and Mark
We narrow the leak to a spot you could cover with a dinner plate, then mark it with tape on the floor. You see exactly where the break is before anyone touches a saw. Pipe locators confirm depth so we know what we are cutting into.
Findings and Repair Plan
We walk you through what we found, show you the readings, and give you the repair options with pricing. If a reroute makes more sense than opening the slab, we tell you that straight. No pressure either way.
Equipment and Methods We Use
Sewerin Acoustic Listening Devices
Pick up the sound of water escaping under pressure through concrete and soil. We use these to trace the leak path along the pipe.
Flir Thermal Imaging Cameras
Show temperature differences under the slab. Hot-water leaks read as warm stripes; cold-line leaks read as cool spots.
Pressure Testing Gauges
Confirm whether the leak is on the supply side by isolating the line and watching for pressure drop with all fixtures closed.
RIDGID Inspection Cameras
Check drain lines and accessible pipe interiors when the leak source is ambiguous between supply and drain.
SubSurface Instruments Pipe Locators
Confirm pipe depth and path before we cut, so we know exactly what is under the marked spot.
LeakTronics Correlation Gear
Cross-check acoustic readings on longer pipe runs where a single listening point is not enough to pinpoint the break.
Moisture Meters
Map the wet zone in carpet, drywall, and baseboards to confirm how far moisture has traveled from the leak.
IAPMO Uniform Plumbing Code Compliance
All isolation, testing, and repair work follows the Uniform Plumbing Code as adopted in New Jersey. That means proper backflow protection, correct materials, and testable joints.
When to Call for Electronic Leak Detection
You got a water bill that is double or triple your normal usage in Kearny and nothing inside is leaking.
We run a full pressure test on the supply line, then sweep the slab with acoustic and thermal equipment. If the leak is underground, we mark it and quote the repair. You know within a few hours whether you have a slab leak or a simpler problem, and you have a repair number to work from.
A section of your floor is warm to the touch and you have hot-water heat or a hot-water line running under it.
Thermal imaging pinpoints the warm stripe, and acoustic gear confirms the break. We check whether a reroute through the wall is cheaper than opening the slab. The leak gets fixed with the smallest possible opening, and your floor stops heating up.
You are buying a Kearny home built before 1970 and want to know if the copper under the slab is sound.
We run a pre-purchase detection sweep: pressure test, acoustic listen, and thermal scan. You get a written report on the condition of the under-slab lines. You negotiate with real information instead of hoping the inspection caught it.
Water is coming up through a basement floor after heavy rain and you cannot tell if it is a slab leak or groundwater.
We isolate the domestic water line and pressure test it. If it holds, the water is not from your plumbing. If it drops, we locate the break. You stop chasing the wrong problem and fix the right one.
How Electronic Leak Detection Runs in Kearny
Kearny sits on a mix of older housing stock and post-war ranches, and the plumbing under those slabs tells you a lot before you even start testing. Pre-1970 homes usually have copper pipes that have been sitting in Hudson County soil for decades, and copper thins out where soil shifting and winter freeze-thaw have worked the line. We see a spike in calls from the 07032 ZIP code every January and February when the ground moves. The Passaic River side of town has a higher water table, which changes how moisture reads under a slab and means we lean harder on pressure testing to separate a real leak from groundwater. If you are searching for electronic leak detection Kearny NJ near me, we can usually be on site the same day and have findings in your hands before dinner.
- Arlington ManorMostly post-war ranches with copper supply lines under the slab. We see pinhole leaks near the water heater feed and along the main run to the kitchen.
- Belleville BorderOlder two-families with shared service lines. Detection here often means testing both units to find which side of the meter the leak sits on.
- Belgrove Drive AreaMixed residential and commercial blocks. Slab leaks in storefronts need after-hours scheduling so we are not testing during business hours.
- Passaic River SideHigher water table means more groundwater in basements. We pressure test first to rule out plumbing before blaming the water table.
- Winter freeze-thaw cycles moving the soilGround movement stresses copper lines and opens pinholes. Most Kearny slab leak calls come in during January and February.
- Pre-1970 copper under original slabsDecades of corrosion thin the pipe wall. Detection has to distinguish between a single pinhole and a line that needs full replacement.
From problem to finished result.
Pinhole Copper Leak in Arlington Manor
BeforeA homeowner on the Arlington Manor side had a water bill that jumped from $90 to $280 in one quarter. No visible water, no wet spots, but the meter spun with everything off. They had already had one contractor suggest breaking up the whole kitchen floor.
AfterWe pressure tested the supply line, confirmed a drop, and swept with acoustic and thermal gear. The leak was a pinhole in the hot-water copper about 14 inches from the kitchen wall. One 2-by-2 foot opening, repaired in three hours, and the next bill came back to $95.
We recommended a yearly meter check with all fixtures off. If the dial moves, call before the bill spikes. Catching it early keeps the repair small.
Warm Floor Traced to Water Heater Feed
BeforeA Belleville customer had a warm stripe running across the hallway floor and assumed the worst: a slab leak under the whole run. They were ready to approve a full floor tear-out and reroute.
AfterThermal imaging showed the warm zone was short and localized near the water heater closet. Acoustic testing confirmed the leak was on the feed line, not the slab run. We repaired the accessible section in under two hours and the floor cooled down within a day.
We suggested insulating the exposed feed line and checking the water heater pan monthly. Small drips there are easy to catch before they spread.
Two-Family Supply Line Isolated
BeforeA Kearny two-family near the Belleville border had water showing up in the downstairs unit's bathroom. Both tenants blamed each other's plumbing and nobody could agree on who was responsible for the repair.
AfterWe tested both units separately with pressure gauges and isolated the leak to the upstairs supply line. The written findings settled the question. One small slab opening, repaired the same day, and the downstairs ceiling dried out over the following week.
We recommended both units check their meter dials monthly. In shared buildings, catching a leak early avoids the argument about who pays.
Problems Electronic Leak Detection Kearny NJ Solves
Most slab leaks announce themselves in ways homeowners misread. Here are the calls we get most often in Kearny and what is usually behind them.
Water bill jumped with no visible leak
We pressure test the supply line first. If it holds, we check the meter and fixtures. If it drops, we sweep with acoustic and thermal gear until we find the escape point and mark it. A hidden slab leak can waste thousands of gallons a month and quietly undermine the soil under your foundation.
Warm spot on the floor that keeps growing
Thermal imaging shows the warm stripe immediately. We confirm with acoustic listening, then give you the choice of a spot repair or a reroute through the wall. A hot-water line leaking under the slab heats the concrete and can crack tile or warp hardwood within weeks.
Sound of running water when everything is off
We isolate the line and listen with Sewerin acoustic devices to separate a slab leak from a toilet flapper or a drain issue. You get a straight answer on which it is. That noise is water escaping under pressure. Left alone it erodes soil, shifts the slab, and can crack the foundation.
Damp carpet or baseboards with no obvious source
We use moisture meters to map the wet zone, then trace it back to the pipe. Electronic detection finds the source so drying and repair target the right area. Moisture wicking up from a slab leak feeds mold growth behind baseboards and under padding within a few weeks.
We find the leak first, so you only open what has to be opened.
No Guesswork Demolition
We mark the leak within a few inches before any concrete comes up. On a typical Kearny slab job that means one 2-by-2 foot opening instead of a trench across the living room. You save the flooring, the patching, and two days of dust.
Same-Day Answers
Digital leak detection in Kearny NJ same day means you are not waiting a week to learn whether your water bill problem is a slab leak or a running toilet. We test, confirm, and hand you findings in one visit.
Lower Water Bills Fast
A slab leak can push a Kearny household past 15,000 gallons a month without a single visible puddle. Once we isolate the line and repair it, most customers see the next billing cycle drop back to normal usage.
Stops Mold Before It Starts
Hidden water under a slab wicks into baseboards and carpet tack strips within weeks. Catching it with electronic leak detection in Kearny, New Jersey means drying a small area instead of remediating a whole room.
Electronic Leak Detection Pricing
Detection pricing in Kearny for 2026 runs $250 to $550 for most residential calls, quoted flat before we start. What moves the number is how many lines we test, whether it is a slab or a wall, and whether we need to isolate multiple units. Repair is always quoted separately once we know what we are dealing with, so you approve it before any work begins. We do not charge hourly for the search, which means a tricky leak does not cost you more than a simple one.
What your estimate is based on
- Number of Lines TestedA single supply line is straightforward. Testing hot and cold separately, plus a drain line, adds time and equipment setup to the call.
- Slab vs Wall vs ExteriorUnder-slab leaks need the full acoustic and thermal sweep. Wall leaks are often faster to isolate. Buried exterior lines need pipe locators and more ground coverage.
- Multi-Unit IsolationTwo-families and small commercial buildings require testing each unit separately to find which side of the meter the leak sits on. That adds a step but settles responsibility.
- Access and Floor CoveringTile, hardwood, and carpet all affect how well acoustic and thermal readings come through. We adjust the approach, which can add time on dense floors.
- Emergency TimingAfter-hours and weekend calls carry a higher rate because we are pulling a technician off scheduled work. Same-day weekday scheduling stays at the standard rate.
$250 - $550 for most residential detection calls The detection fee is a fraction of what exploratory demolition costs. One wrong cut in a slab can run into thousands in flooring and concrete work. Paying for accurate detection first is the cheapest part of the whole job.
What you receive
Clear records you can keep and share.
Marked leak location
Taped on the floor, depth confirmed
Repair options
Spot repair or reroute, priced
What to understand before you approve any slab work
Detection comes before demolition, always. If a contractor wants to open your floor without testing first, you are paying for their guess.
Pressure test first
A dropping gauge with all fixtures closed confirms a supply-side leak. If the gauge holds, the problem is elsewhere and you just saved a slab cut.
Two readings agree
Acoustic and thermal results have to match before we mark a spot. One reading alone can be fooled by drains, groundwater, or radiant heat.
Reroute is an option
Sometimes running a new line through the wall costs less than opening the slab. We price both and tell you which makes more sense for your house.

What Kearny Customers Say
Most residential detection calls in Kearny run $250 to $550 in 2026, depending on how many lines we test and whether it is a slab, wall, or buried exterior line. That covers the full inspection and written findings. Repair is quoted separately once we know what we are dealing with, so you approve the number before any work starts.
It is a non-invasive way to find hidden water leaks using sound and heat instead of demolition. We pressurize the line, listen with acoustic devices, and scan with thermal cameras to locate the escape point. In Kearny, that usually means finding a pinhole in copper under a slab without breaking the floor to look for it.
Yes. Combining acoustic listening with thermal imaging and pressure testing pins the leak within a few inches on most jobs. No method is perfect on every pipe, which is why we cross-check two or three tools before we mark the floor. If the readings disagree, we keep testing until they line up.
That is exactly what it is built for. Slab leaks hide under concrete where you cannot see them, but they still make noise and still change the floor temperature. Electronic leak detection for slab leaks in Kearny NJ finds them without exploratory demolition, which is why we run it before any repair quote.
