What is included
What our PEX pipe leak repair includes
Every PEX repair job includes detection, repair, pressure testing, and a concrete patch. We do not sub out the detection or the repair. Here is what you get when you book us.
Full leak detection
We use an acoustic leak detection microphone, a thermal imaging camera, and a pressure testing gauge to confirm the leak and pinpoint its location. Detection is included in the repair price, not billed as a separate add-on.
Small access cut
We cut the smallest opening we can, usually 2 by 2 feet, using a concrete saw. Drop cloths go down first, and we vacuum the dust as we cut. You will not come home to a construction site.
Code-correct PEX repair
We replace the failed section with new PEX and fittings from Uponor, SharkBite, Mueller, or NIBCO, matching what is already in your system. Every crimp is checked against Uniform Plumbing Code (UPC) standards.
80 psi pressure test
Before we patch anything, we pressurize the repaired line to 80 psi for 15 minutes. If the gauge holds, the repair is good. If it moves, we keep looking. No slab gets closed on a guess.
Concrete patch and cleanup
We pour a concrete patch matched to your slab, let it set, and clean up the work area. You get photos of the repair and a written warranty before we leave.

Service overview
What PEX pipe leak repair Venice FL actually involves
PEX pipe leak repair Venice FL means locating a failure in cross-linked polyethylene water line and restoring it without tearing your house apart. PEX is flexible tubing that replaced copper in most Florida homes built after the mid-1990s, and it usually fails at a fitting, a crimp ring, or a spot where abrasive backfill rubbed through the wall. We start with an electronic leak detection wand and a pressure testing gauge to confirm the line is losing water, then use a pipe locator to map exactly where it runs under the slab.
Venice sits on sandy soil and a high water table, so under-slab lines stay damp and shift more than they would inland. That is why PEX slab leak repair Venice FL calls come in year-round here, especially in homes near the Venice Canals and Marina Peninsula. If you have noticed a warm floor spot, a water bill that jumped $80 or more, or the sound of running water when everything is off, you likely need PEX pipe leak repair in Venice FL near me service before the slab wicks moisture into your flooring.
- Same-day leak location — We carry an acoustic leak detection microphone and a Fluke thermal imaging camera on every truck. That means we can pinpoint a PEX leak repair Venice FL job in one visit instead of opening three wrong spots in your floor. Most locations take 45 to 90 minutes.
- Minimal concrete cutting — We use a concrete saw to open only the slab we have to. A typical PEX pipe leak repair Venice job needs a 2-by-2-foot access cut, not a trench across the living room. Smaller cuts mean faster patching and less dust in your house.
- Code-correct PEX fittings — We stock Uponor, SharkBite, Mueller, and NIBCO fittings so the repair matches what is already in your wall. Every crimp is checked against Uniform Plumbing Code (UPC) standards, and we pressure-test at 80 psi before closing the slab.
- 24/7 emergency response — Water does not wait for business hours. Call (941) 477-1483 at 2 a.m. and we roll a truck for emergency PEX pipe leak repair 24/7 Venice FL calls. We shut the leak down, stabilize the area, and schedule the permanent fix.
- We locate before we cut — Too many companies open a slab and hope. We use an acoustic leak detection microphone and a thermal imaging camera first. That means one access hole, not three. On a recent Venice Gardens job, we saved the homeowner about $1,400 in unnecessary concrete work by locating first.
- Upfront pricing, no surprises — You get a flat price before we start. Detection runs $250 to $450, and a standard under-slab PEX repair runs $1,200 to $2,800 depending on depth and access. No hourly billing, no surprise add-ons when the concrete is thicker than expected.
- Emergency service that answers — Our phone is answered by a person, not a call center. For PEX pipe leak repair 24/7 Venice FL emergencies, we dispatch a licensed plumber, not a helper with a wet-vac. We can shut down the leak and stabilize your home until the permanent repair is done.
- We fix the cause, not just the leak — A PEX leak under a slab usually means abrasive backfill, a bad crimp, or soil movement. We inspect the surrounding line with a video pipe inspection camera and replace any section that shows the same wear. That is how you avoid a second repair six months later.
The service timeline
How our PEX leak repair process works
Phone triage
We ask three questions: where is the water showing up, what does your meter do with everything off, and how old is the home. That tells us whether you have a slab leak or a fixture leak. Takes five minutes, and we give you a straight answer on what to shut off before we arrive.
On-site detection
Our technician walks the house with a Sewerin acoustic microphone and a FLIR infrared camera. We listen for the hiss of pressurized water and look for temperature differences on the floor. Most PEX pipe leak repair Venice Florida jobs are located in under an hour.
Access and repair
We mark the spot, lay drop cloths, and cut a small access hole with a concrete saw. Then we expose the failed section, cut out the bad PEX, and install new fittings. A straightforward repair takes two to four hours from cut to patch.
Pressure test
Before anything gets covered, we cap the line and pressurize it to 80 psi for 15 minutes. If the gauge holds, the repair is good. If it drops, we keep looking. No slab gets closed until the pressure testing gauge sits still.
Patch and walkthrough
We pour a concrete patch, let it set, and walk you through what we found and what we fixed. You get photos of the repair and a written warranty. We also check your water meter one last time with you standing there.

Tools and methods we use
Acoustic leak detection microphone (Sewerin)
Listens for the hiss of pressurized water escaping a PEX line under the slab. It lets us confirm the leak before we cut.
Thermal imaging camera (FLIR)
Shows warm spots on the floor where hot-water PEX lines are leaking. It is a fast, non-destructive first step.
Electronic leak detection wand
Picks up moisture and sound signatures in the slab. We use it alongside acoustic gear to double-check the location.
Pressure testing gauge
Pressurizes the repaired line to 80 psi for 15 minutes. If the gauge holds, the repair is good.
Video pipe inspection camera (RIDGID)
Lets us see inside the PEX line to check for cracks, bad crimps, or abrasive wear before we close the slab.
Pipe locator
Maps exactly where the PEX line runs under the slab so we cut in the right place the first time.
Concrete saw and jackhammer (Milwaukee)
Opens a small access hole in the slab. We use dust control and drop cloths to keep the work area clean.
Acoustic slab leak detection
We place a Sewerin microphone on the floor and listen for the frequency of pressurized water escaping a PEX line. It is the fastest way to confirm a slab leak before we commit to a repair plan.
Thermal imaging survey
A FLIR infrared camera scans the floor for temperature differences caused by hot-water leaks. We use it alongside acoustic gear to double-check the leak location.
80 psi pressure test
After the repair, we cap the line and pressurize it to 80 psi for 15 minutes. If the gauge holds, the repair is good. If it drops, we keep looking. No slab gets closed on a guess.
Code-correct PEX fitting installation
We install Uponor, SharkBite, Mueller, or NIBCO fittings that match your existing system. Every crimp is checked against Uniform Plumbing Code (UPC) standards and the Florida Building Code.
Concrete patch and moisture check
We pour a concrete patch matched to your slab and check the surrounding area with a moisture meter. That confirms no water is still spreading under your flooring.
Where this service helps

Local execution
How PEX pipe leak repair runs in Venice
Venice sits on sandy soil with a high water table, and that combination is hard on under-slab PEX lines. The soil shifts more than inland clay, which stresses fittings and crimp rings. Homes near the Venice Canals and Marina Peninsula deal with the highest moisture, while older builds around Downtown Venice often have original under-slab lines that are reaching the end of their service life. We pull Sarasota County permits when the job requires it and follow the Florida Building Code on every slab penetration. If you need PEX pipe leak repair in Venice FL near me service, we are local, and we know which neighborhoods see the most under-slab failures. Most repairs are done in one day, and we pressure-test at 80 psi before we patch.
Venice Gardens
Many homes here were built in the 1980s and 1990s with early PEX or CPVC under the slab. We see fitting failures more than pipe-wall failures in this area.
Downtown Venice
Older bungalows near the historic district often have original under-slab lines. We use smaller access cuts here to preserve original flooring.
Marina Peninsula
The high water table near the marina keeps soil damp year-round, which accelerates corrosion and fitting wear on under-slab PEX.
Venice Beach
Salt air and sandy soil near the beach mean more soil movement. We see PEX leaks here after heavy summer rains.
Silver Strand
Newer construction with PEX throughout. Failures here are usually bad crimps or abrasive backfill, not age-related.
High water table near the coast
Damp soil keeps under-slab lines wet and accelerates fitting corrosion. We see more PEX leaks in coastal neighborhoods than inland.
Sandy, shifting soil
Soil movement stresses PEX lines and can pull fittings loose. We inspect the surrounding line after every repair to catch the same wear.
Summer storm season
Heavy rain raises the water table fast, which can expose existing leaks. We get more emergency calls from June through September.
Older housing stock near Downtown
Homes built before 1990 may have original under-slab lines. We check the whole run, not just the failed spot, on these jobs.
Before and after
What a successful service visit changes.
Kitchen slab leak in Venice Gardens
Before
A homeowner noticed a $160 jump in the water bill and a warm spot near the kitchen. A previous plumber wanted to open 12 feet of tile. We used acoustic and thermal gear to pinpoint a single failed PEX fitting under the slab.
After
We cut a 2-by-2-foot access hole, replaced the fitting with an Uponor coupling, and pressure-tested at 80 psi. The repair held. The homeowner saved about $1,400 in unnecessary concrete and tile work.
Maintenance: We recommended checking the water meter monthly with everything off. If it spins, call us before the bill spikes again. A $250 detection visit beats a $2,000 slab repair.
Hot-water PEX leak near Venice Beach
Before
A rental property had a warm spot on the bathroom floor and a tenant complaining about the heat. The slab was original 1990s construction with PEX throughout. We scanned with a FLIR camera and confirmed a hot-water leak under the slab.
After
We opened a small access, replaced the failed section with Mueller PEX and SharkBite fittings, and pressure-tested at 80 psi. The warm spot was gone the same day, and the tenant renewed the lease.
Maintenance: We told the owner to have the line pressure-tested annually. On rental properties, a $300 test can catch a leak before it damages flooring and costs $2,500 to fix.
Emergency PEX leak on Marina Peninsula
Before
A homeowner called at 11 p.m. with water pooling on the floor near the hallway. The main was shut off, but the slab was already wet. We dispatched a licensed plumber within the hour to stabilize the situation.
After
We located the PEX leak with an acoustic microphone, repaired the line the next morning, and pressure-tested at 80 psi. The concrete patch was done by noon. Total downtime was under 12 hours.
Maintenance: We set the homeowner up with a moisture meter check two weeks later to confirm the slab dried out. No secondary damage, no mold.
Problems we solve
Problems we solve with PEX pipe leak repair Venice
A hidden PEX leak does not fix itself. These are the problems we see most often in Venice homes and how we handle them.
Water bill spiked with no visible leak
A $80 to $200 monthly increase usually means water is escaping under the slab. Left alone, it can undermine the foundation and soak your flooring from below. We test your meter with everything off, then use acoustic and thermal gear to locate the PEX leak. Most are found in under an hour. We repair the line and pressure-test it before patching the slab.
Warm spot on the floor
A warm spot usually means a hot-water PEX line is leaking under the slab. The heat damages flooring adhesive and can warp wood or tile over time. We scan the floor with a FLIR infrared camera to confirm the leak location, then cut a small access hole and repair the PEX line. The warm spot is gone the same day.
Sound of running water when everything is off
That hiss is pressurized water escaping a PEX line. It can run for weeks before surfacing, and by then the damage is expensive. We use a Sewerin acoustic microphone to hear the leak through the slab, then a pipe locator to map the line. We repair the failed section and test the line at 80 psi before closing.
Previous repair failed in the same spot
If a PEX repair fails twice, the surrounding line is usually bad too. Patching the same spot again wastes money and tears up your floor a second time. We inspect the surrounding line with a video pipe inspection camera and replace any section showing the same wear. If the whole run is failing, we give you a repipe number so you can compare.
Pricing and expectations
What PEX pipe leak repair costs in Venice
$250 - $2,800 depending on scope
Typical 2026 pricing in this area runs $250 to $450 for detection and $1,200 to $2,800 for an under-slab PEX repair. The range depends on how deep the line sits, whether we hit rebar, and how much concrete we have to open. We give you a flat price before we start cutting, so you are not watching a clock. If the repair is straightforward, it lands on the low end. If the line is under a thick slab or behind a cabinet, it moves up. We also quote repiping if the line is failing in multiple spots, so you can compare the numbers.
A $1,500 repair now beats a $6,000 flooring and foundation job later. We locate first, cut small, and pressure-test before we close. That is how you avoid paying twice for the same leak.
Depth of the line
PEX lines closer to the surface are faster to access. Lines 6 inches or deeper under the slab take longer to expose and patch, which adds labor and concrete work to the job.
Concrete thickness and rebar
Thicker slabs and rebar slow down cutting. If we hit rebar, we have to cut around it, which adds time. We check slab thickness before quoting so there are no surprises.
Access and flooring
Tile, hardwood, and engineered flooring all come up differently. If the leak is under a cabinet or in a tight hallway, access is harder and the repair takes longer.
Number of failed sections
One failed fitting is a straightforward repair. If the surrounding line shows the same wear, we replace more of it. That prevents a second repair six months later.
Emergency vs. scheduled
After-hours emergency calls carry a higher dispatch rate. If you can schedule the repair for the next business day, the price is lower. We tell you both numbers on the phone.

Customer stories
What Venice homeowners say
Dana R.Homeowner, Venice Gardens
Our water bill jumped $140 in one month and we could not find a leak. Venice SlabGuard came out with a thermal camera and found a PEX leak under the kitchen slab in about 40 minutes. They cut a small hole, replaced the fitting, and pressure-tested it. The patch looks clean and the bill is back to normal.
Miguel S.Homeowner, Downtown Venice
We had a warm spot on the floor for weeks and kept ignoring it. Turned out to be a hot-water PEX line leaking under the slab. They located it with an acoustic microphone, repaired it the same day, and showed me photos of the repair before they patched the concrete. No surprises on the price.
Karen L.Property Manager, Venice Beach
I manage three rentals near the beach and PEX leaks are a recurring headache. Venice SlabGuard has handled two under-slab repairs for me. Both times they located the leak without tearing up the whole floor and pressure-tested before closing. They also gave me a written warranty, which my owners appreciate.
How much does PEX pipe leak repair cost in Venice FL?
Most PEX pipe leak repair in Venice FL runs $1,200 to $2,800 for an under-slab fix, and $250 to $450 for detection alone. The price depends on how deep the line sits, whether we hit rebar, and how much concrete we have to open. We give you a flat number before we start cutting.
Can you repair a PEX pipe under slab in Venice?
Yes. We repair PEX under slab in Venice every week using a small access cut and code-correct fittings. We locate the failure with acoustic and thermal gear first, then cut a 2-by-2-foot opening, replace the bad section, and pressure-test at 80 psi. Most repairs are done in one day.
Why do PEX pipes leak in Venice?
PEX pipes in Venice leak for three main reasons: abrasive backfill rubbing through the tube wall, failed crimp rings at fittings, and soil movement from our high water table. The sandy soil here shifts more than inland clay, which stresses under-slab lines. Most failures we see are at fittings, not in the middle of a straight run.
