What is included
What our slab leak service includes
Every slab leak call includes the full detection sequence and a written location report. Repair is quoted on site once we know the depth and material. Here is what is covered as standard and what we price separately so there are no surprises.
Full system pressure isolation
We shut down fixtures, irrigation, and the water heater, then watch the pressure testing gauge for 20 to 30 minutes. This confirms whether the loss is under the slab or somewhere above it. It is the step that prevents us from opening a floor for nothing.
Acoustic and thermal pinpointing
We combine an acoustic leak detection microphone with a thermal imaging camera and a pipe locator to trace the line and mark the break. You get the location marked on the floor and a written report with depth and material notes.
Code-correct pipe repair
The failed section is cut out and rebuilt with PEX piping or copper pipe, new pipe fittings, and proper sealant. Every joint is built to NC plumbing code and wrapped for soil contact. We do not patch with epoxy pipe repair on pressurized lines.
Pressure test and documentation
After repair we re-pressurize the line and hold it under test for 30 minutes. You receive a written record of the test, which is useful for insurance claims and for resale. A repair without a documented test is an unfinished repair.
Slab patch and cleanup
We backfill the access point, patch the concrete, and clean the work area before we leave. Most patches are 18 inches square or smaller. We also check nearby flooring for moisture damage and tell you what to watch over the next week.

Service overview
Slab Leak Detection & Repair in Greenville: what the job actually involves
Slab Leak Detection & Repair in Greenville is the process of locating a pressurized water line break beneath a concrete foundation and repairing it without unnecessary demolition. We pressurize the system, listen for the hiss with an acoustic leak detection microphone, and confirm the hot spot with a thermal imaging camera. Once we know the depth and direction, we open a small access point, cut out the failed section, and rebuild it in PEX piping or copper pipe. Then we pressure-test the line and restore the slab.
Greenville's clay-heavy soil and older post-war slab homes push water lines through constant expansion and contraction, which is why under slab leak detection Greenville calls spike after every hard freeze. A pinhole in copper pipe can waste 30 to 60 gallons a day before you ever see a wet spot. We also check the pressure testing gauge for whole-house spikes that point to a foundation water leak repair near me situation rather than a fixture drip.
- Stop the water bill bleed — A slab leak can add $80 to $200 a month to a Greenville water bill. We isolate the line, repair it, and re-read the meter before we leave, so you can see the usage drop the same day. Most customers recover the repair cost within a few billing cycles.
- Protect the foundation — Water saturating Pitt County clay softens the soil under a slab and causes differential movement. Cracks in drywall corners and sticking doors often trace back to a foundation leak repair Greenville NC job that was put off too long. Fixing the pipe early protects the slab itself.
- Keep floors and cabinets dry — Hot-water slab leaks warp laminate, lift tile, and swell cabinet toe kicks. We pinpoint the break before it spreads, so repair usually means one small access cut instead of replacing an entire room of flooring. That difference alone saves thousands.
- Avoid mold and musty air — Trapped moisture under a slab feeds mold in carpet pad and baseboards. A moisture meter reading above 20 percent in a slab-adjacent wall is a red flag. Once the pipe is repaired and the area dries, that musty smell in the hallway usually disappears within a week.
- Pinpoint accuracy — We mark the break within 6 to 12 inches before cutting. That accuracy is why most of our slab repairs open a single 18-inch access point instead of a trench across the room. Less concrete, less dust, faster patch, lower bill.
- 24/7 emergency response — Burst pipe and slab leaks do not wait for business hours. We answer the phone at 2 a.m. after a freeze and roll a truck to Greenville, Winterville, and Ayden. Emergency isolation stops the water damage while we schedule the permanent repair.
- Upfront pricing, no surprises — You get the detection price and the repair range before we open anything. If the leak turns out to be a foundation water leak repair near me job with a deeper break, we tell you on site and you decide. No change orders after the concrete is cut.
- Repairs that pass inspection — Every repair is built to NC plumbing code with IAPMO-certified fittings and pressure-tested before backfill. We document the test, which matters if you sell the home or file an insurance claim. A repair that cannot pass inspection is not a repair.
The service timeline
Our slab leak detection and repair process
Phone triage
We ask about your water bill, warm floor spots, and meter behavior while you are still on the phone. That five-minute conversation tells us whether you likely have a slab leak, an irrigation line leak, or a running toilet. We schedule a same-day or next-morning visit and give you an arrival window.
Pressure isolation
On site, we shut off fixtures and irrigation, then watch the pressure testing gauge. If the system loses pressure with everything closed, the leak is underground. This step takes 20 to 30 minutes and separates a true slab leak from a dripping faucet or a leaking water heater.
Acoustic pinpointing
We walk the slab with an acoustic leak detection microphone and a pipe locator to trace the line. A thermal imaging camera confirms the hot or cold signature. Most residential slabs are pinpointed within 45 to 90 minutes, and we mark the access point with tape before any cutting starts.
Repair and rebuild
We open a small access point, cut out the failed section, and rebuild it with PEX piping or copper pipe and new pipe fittings. The joint is sealed with pipe sealant and Teflon tape, then wrapped for soil contact. Repair typically runs two to four hours depending on depth and how much concrete we open.
Test and restore
We re-pressurize the line, hold it under test for 30 minutes, and check every fixture for air. Once it holds, we backfill, patch the slab, and clean the work area. You get a written summary of what failed, where it was, and what to watch for next winter.
Tools and methods01 02 03 04 05 06 07 08 09 10 11
Tools and methods we use
Acoustic leak detection microphone
Listens for the specific frequency of pressurized water escaping a pipe under concrete. It lets us mark the break within inches before we cut.
Thermal imaging camera (Fluke)
Shows temperature differences on the slab surface. A hot-water leak reads as a warm streak that traces the line path and confirms the acoustic finding.
Pipe locator (RIDGID)
Traces the buried line path so we know exactly where the pipe runs under the slab, which keeps the access cut small and accurate.
Pressure testing gauge
Confirms whether the system loses pressure with all fixtures closed. This single test separates a slab leak from a fixture drip in about 20 minutes.
Moisture meter (Klein Tools)
Reads moisture content in drywall, baseboards, and carpet pad near the slab edge. Anything above 20 percent tells us water has traveled from the break.
Tracer gas leak detector (Sewerin)
Used on low-pressure or hard-to-hear lines where acoustic gear struggles. A safe gas mixture is pushed into the line and traced at the surface.
Video pipe inspection camera (General Pipe Cleaners)
Confirms pipe material and condition inside the line. It shows whether the failure is a pinhole, a joint, or a full section that needs replacement.
Pressure isolation testing
We close every fixture, irrigation zone, and the water heater, then watch the gauge. A pressure drop with everything closed confirms an underground loss. This method rules out the cheap causes first and keeps you from paying for a slab repair you do not need.
Acoustic and thermal correlation
We do not trust one tool alone. The acoustic microphone finds the sound, the thermal camera confirms the heat signature, and the pipe locator maps the path. When all three agree, we cut. That correlation is why our access points stay small.
Code-correct section replacement
We cut out the failed section and rebuild it with PEX piping or copper pipe, new pipe fittings, and proper sealant. Joints are wrapped for soil contact and built to NC plumbing code. We do not use epoxy pipe repair on pressurized lines.
Post-repair pressure hold
After the repair we re-pressurize and hold the line under test for 30 minutes. If it holds, we backfill and patch. If it does not, we keep working. No repair is finished until the gauge says so.
Where this service helps
When Greenville homeowners call us
A 1965 slab ranch near Evans Street shows a warm kitchen floor and a water bill up $120 in one month.
We isolate the hot-water side, pinpoint the copper pipe break under the kitchen with acoustic and thermal gear, and open one 18-inch access point. The failed section is replaced with PEX piping and pressure-tested. Repair completed in three hours. The next water bill returned to its normal range, and the tile was re-set over the patch the following week.
A rental property near ECU has a tenant reporting a musty smell and a soft spot in the hallway carpet.
A moisture meter reads 24 percent at the baseboard. We pressure-test the system, locate a cold-water slab leak, and repair it between tenant shifts to avoid displacing anyone. The leak was fixed in one afternoon, the carpet pad was replaced, and the musty odor cleared within a week. The owner received the pressure-test documentation for insurance.
A homeowner in the 27834 ZIP code hears running water at 2 a.m. with every fixture off.
We answer the emergency line, walk them through shutting the main valve, and roll a truck. The ultrasonic leak detector traces the sound to a cracked fitting under the garage slab. Emergency isolation stopped the water loss that night, and the permanent repair was completed the next morning. No flooring was lost.
A Winterville family returns from vacation to a $340 water bill and a hot spot on the bathroom floor.
We rule out the toilet and irrigation first, then pinpoint a hot-water slab leak under the bathroom vanity. The repair is made through a small access cut in the adjacent closet. The line held pressure on the first test, the bill dropped back to normal, and the closet patch was painted to match within two days.
Local execution
How slab leak repair runs in Greenville, NC
Greenville sits on expansive clay soil that swells when wet and shrinks when dry, and that cycle is hard on under-slab water lines. Our January freezes push pipes to the breaking point, and the calls come in fast once the thaw starts. Older slab homes near downtown and around the ECU campus often still have original copper pipe, which develops pinholes after 40 to 50 years. Newer builds in the 27858 and 28590 ZIP codes use PEX piping, but fittings and manifolds still fail. We follow NC plumbing code on every repair and pressure-test before backfill. If you are searching for under slab water leak repair Greenville NC, we handle the detection, the repair, and the slab patch without subcontracting any of it. Pitt County homes on crawlspaces get a different approach, and we check that first so you are not paying for slab work you do not need.
ECU / Downtown Greenville
A high concentration of 1950s and 1960s slab homes with original copper lines. Pinhole leaks are common, and rental turnover means leaks often go unnoticed for months.
Evans Street corridor
Mid-century ranches on shallow slabs. We often pinpoint breaks within a few feet of the kitchen or hall bath, where the original line layout concentrates fittings.
Winterville
A mix of older slab homes and newer subdivisions. Newer PEX manifolds sometimes fail at the crimp ring, which reads as a slab leak on the meter.
Tar River corridor
Soil here stays wetter longer after rain, so foundation movement and pipe stress show up sooner. We check soil moisture around the slab edge as part of the inspection.
Expansive Pitt County clay soil
Wet-dry cycles move the slab and stress buried lines. This is the leading cause of pinhole leaks in copper pipe under Greenville homes, and it is why we wrap every repaired joint for soil contact.
January freeze and thaw cycles
Pipes in exterior walls and under unheated slabs freeze, then burst as they thaw. We see a spike in emergency calls the week after a hard freeze, usually for burst pipe repair and slab leaks together.
Older copper plumbing in post-war homes
Copper that has been in the ground 40 to 50 years develops pinholes from soil corrosion. When we open a line, we inspect the surrounding section and tell you if more failures are likely.
High water table near the Tar River
A high water table can mask a slab leak because the ground is already wet. We rely on pressure testing and acoustic gear rather than visible wet spots to confirm the break.
Before and after
What a successful service visit changes.
High water bill traced to a hot-water slab leak
Before
A homeowner in the 27858 ZIP code saw the water bill jump from $65 to $190 in one month. The kitchen floor was warm near the sink, and the water heater ran constantly. Two other plumbers had suggested replacing the whole floor.
After
We isolated the hot-water side, pinpointed the break under the kitchen with acoustic and thermal gear, and opened one 18-inch access point. The copper section was replaced with PEX piping and pressure-tested for 30 minutes. The next bill came in at $71.
Maintenance: We recommended checking the water meter monthly with all fixtures off. A slow spin means a new leak is starting, and catching it early keeps the access cut small.
Musty smell and soft carpet from a cold-water break
Before
A rental near ECU had a musty hallway and a soft spot in the carpet. The tenant had mentioned it for weeks. A moisture meter read 24 percent at the baseboard, and the water bill was up $90.
After
We pressure-tested the system, located a cold-water slab leak under the hallway, and repaired it in one afternoon between tenant shifts. The carpet pad was replaced, and the moisture reading dropped to 11 percent within four days.
Maintenance: We told the owner to re-check the baseboard with a moisture meter after the next rainy season. If it climbs again, the soil around the slab edge may need regrading.
2 a.m. running water sound stopped same night
Before
A homeowner in the 27834 ZIP code heard running water at 2 a.m. with every fixture off. The main valve was open, and the sound was loudest near the garage. They called our emergency line.
After
We walked them through shutting the main valve, then rolled a truck. The ultrasonic leak detector traced the sound to a cracked fitting under the garage slab. Emergency isolation stopped the loss that night, and the permanent repair was done the next morning.
Maintenance: We suggested insulating the garage wall lines before the next freeze and checking the pressure gauge seasonally. A 30-minute pressure hold at the start of winter catches small failures early.
Problems we solve
Slab leak problems we solve in Greenville
Most slab leak calls start with one of these four symptoms. Each one has a different fix, and guessing wrong costs money. Here is how we sort them out and what we do about each.
Water bill doubled with no visible leak
You are paying for water that is soaking into the soil under your foundation. Left alone, that water softens Pitt County clay and causes the slab to move, which cracks tile and drywall. We isolate the system with the pressure testing gauge, rule out the toilet and irrigation, then pinpoint the under-slab break with acoustic gear. Most high-bill slab leaks are repaired the same day we find them.
Warm spot on the floor over a hot line
A hot-water slab leak heats the concrete from below and can warp laminate or lift tile within weeks. It also keeps the water heater running constantly, shortening its life. A thermal imaging camera confirms the hot line path, and the acoustic mic marks the break. We cut one small access point, replace the failed copper section with PEX piping, and pressure-test before backfill.
Sound of running water when everything is off
That hiss is pressurized water escaping a pinhole or cracked fitting. It can waste 30 to 60 gallons a day and eventually undermine the slab or flood a nearby room. We use an ultrasonic leak detector and pipe locator to trace the sound to its source. Once located, we repair the section and verify with a 30-minute pressure hold. No more hiss, no more waste.
Cracks in drywall corners and sticking doors
Foundation movement from saturated soil shows up as cracks, uneven floors, and doors that no longer latch. Treating the crack without fixing the water source wastes money. We find and repair the foundation water leak first, then let the soil dry and stabilize. If structural repair is still needed after the pipe is fixed, we tell you honestly and refer a foundation specialist.
Proof behind the promise
Licensed, insured, and documented
How much does slab leak detection cost in Greenville NC?
Most slab leak detection jobs in Greenville run $250 to $450 in 2026, including pressure isolation, acoustic pinpointing, and a written location report. Repair is quoted separately, usually $600 to $2,500 depending on depth, pipe material, and how much concrete we open. We give you both numbers before any cutting starts.
What are signs of a slab leak in Greenville North Carolina?
The four most common signs are a water bill that jumps 20 percent or more with no change in habits, a warm spot on the floor over a hot-water line, the sound of running water when every fixture is off, and cracks appearing in tile or drywall corners. A moisture meter reading above 20 percent near a baseboard confirms it.
Can you repair a slab leak without breaking concrete in Greenville?
Sometimes, yes. If the line is accessible from a crawlspace, garage wall, or exterior stub, we can reroute or sleeve the pipe without touching the slab. For a true under-slab break, we open one small access point, usually 18 inches square, rather than tunneling the whole line. We tell you which route fits your home before work begins.
Who fixes foundation leaks in Greenville NC?
A licensed plumbing contractor with leak detection equipment fixes foundation leaks, not a foundation company. The crack in your drywall is usually a symptom, not the problem. We locate the water source first, repair the pipe, then confirm the soil has stopped moving. If structural repair is still needed, we tell you straight.
