About this service
What PEX Pipe Slab Leak Repair in Venice Really Involves
PEX Pipe Slab Leak Repair in Venice is the process of pinpointing a breach in cross-linked polyethylene water line buried beneath your concrete slab, exposing the failed section, and replacing or coupling it with code-correct fittings. PEX is flexible, so it rarely fails at the pipe body. The weak points are the crimp rings, brass fittings, and any spot where the line was nicked during construction. We pressure-test the whole run, isolate the bad section, and repair it without tearing up your entire floor.
Venice sits on sandy soil and a high water table, and that combination punishes under-slab plumbing. Add our hot, humid summers and the slab movement that comes with them, and PEX fittings start weeping years before you see water. Homeowners in Venice Gardens and South Venice call us most often after a jump in the SWFWMD bill or a warm spot on the tile. If you need PEX slab leak repair Venice FL residents can count on, we run electronic and acoustic detection first so we cut one hole, not five.

What's included
What Our PEX Slab Leak Repair Includes
Every PEX repair we run in Venice includes detection, access, repair, pressure testing, and concrete patch work. You get one price for the whole job, not a menu of add-ons. Here is what is covered.
✓
Acoustic and Thermal Detection
We locate the leak before cutting using a Sewerin acoustic microphone and a Fluke thermal imaging camera. Detection is included in the price, not billed separately. This is the step that keeps your access hole small and your floor intact.
✓
Single Access Point Cut
We cut one clean opening, usually under 14 inches square, and control the concrete dust with a vacuum shroud. You do not get a trench across your living room. The cut is sized to the repair, nothing more.
✓
PEX Repair with Code Fittings
Failed crimp rings, brass fittings, and damaged pipe sections get replaced with new PEX and code-correct couplings. We carry Uponor and SharkBite fittings on every truck, so the repair matches your existing system.
✓
100 PSI Pressure Test
We charge the repaired line to 100 PSI and hold it for 30 minutes while you watch the gauge. If it moves, we keep working. You get a verified dry line before any concrete goes back in the hole.
✓
Matched Concrete Patch
We pour a concrete patch that matches the surrounding slab and finish it flush. The site gets swept clean, and your flooring goes back with the same cuts we made. Most patches are ready for foot traffic within a few hours.
✓
Written Warranty and Report
You get a written summary of the failure, the repair, and the test results, plus a two-year workmanship warranty on the repair. If the same section fails inside that window, we come back and fix it.
How it works
Our PEX Slab Leak Repair Process, Step by Step
01
Phone Triage
We ask three questions: where is the meter spinning, is the floor warm, and do you hear water with everything off. That tells us hot line versus cold line before we roll. You get a straight arrival window, usually 60 to 90 minutes inside Venice. Shut the main valve if you can reach it.
02
Detection and Mapping
On site, we pressurize the system with a pressure testing gauge, then sweep the slab with a Sewerin acoustic microphone and a Fluke thermal imaging camera. A pipe locator maps the PEX run so we know exactly where to cut. Detection takes 30 to 45 minutes on a typical Venice home.
03
Access and Repair
We cut one access point, vacuum the concrete dust, and expose the failed section. The bad fitting or crimp ring comes out, and we install new PEX with code-correct couplings. Repair itself runs one to two hours. We keep the opening as small as the repair allows.
04
Pressure Test and Patch
We recharge the line to 100 PSI and watch the gauge for 30 minutes. Pass, and we pour a matched concrete patch, then reset your flooring. Fail, and we keep hunting before anything gets closed up. You see the gauge reading yourself, so there is no ambiguity.
05
Walkthrough and Warranty
We walk the repair with you, show the test results, and hand over the warranty paperwork. You get a written summary of what failed and why, plus the moisture meter readings we took at the start and end. Total time on site: three to five hours for most jobs.
Tools & methods
Tools and Methods We Use
Purpose-built equipment, used by trained technicians — so the job is done accurately the first time.
Sewerin Acoustic Leak Detection Microphone
Picks up the sound signature of pressurized water escaping a PEX line and isolates it from background noise. It is how we narrow the leak to a few inches before we cut.
Fluke Thermal Imaging Camera
Shows temperature differences on the slab surface that reveal hot and cold line leaks. On PEX jobs, it confirms what the acoustic mic heard.
Pressure Testing Gauge
Charges the repaired line to 100 PSI and holds it for 30 minutes. If the needle moves, the repair is not done. You watch the gauge with us.
Pipe Locator
Maps the PEX run under the slab so we know exactly where the line sits before we mark a cut. It keeps the access point over the leak, not near it.
Moisture Meter
Reads moisture levels in the slab and surrounding walls before and after repair. We use it to confirm the area is drying and to check for secondary damage.
Video Inspection Camera
Lets us look inside accessible sections of the PEX run and confirm fitting condition. It is useful when a line has failed more than once.
RIDGID and Milwaukee Concrete Cutting Tools
Cut clean, controlled access points with dust shrouds attached. Clean cuts mean clean patches, and your floor goes back flush.
Real results
Before and after.
Hot Line PEX Leak, Venice Gardens
Before
A homeowner in Venice Gardens noticed a warm strip on the kitchen tile and a water bill that climbed $90 in one month. The meter spun with every fixture off. We pressure-tested the system, isolated the hot branch with acoustic and thermal detection, and confirmed a failed crimp ring about 9 feet from the manifold.
After
We cut one 12-by-12-inch access point, replaced the failed fitting with new PEX and a code-correct coupling, and held the line at 100 PSI for 30 minutes. The patch went in flush, the tile reset, and the next bill came back to normal. Total time on site: about four hours.
Emergency Cold Line Repair, South Venice
Before
A South Venice homeowner called at 11:20 p.m. with water seeping through the garage slab. The main was shut at the street, but the slab stayed wet. We arrived in 75 minutes, pressure-tested the cold side, and located a split PEX fitting under the garage edge with the acoustic microphone.
After
We opened a 10-by-10-inch access point, replaced the split fitting, and held 100 PSI for 30 minutes by 1:45 a.m. The homeowner had water back that night. We returned the next morning to pour the concrete patch and confirm the slab was drying with a moisture meter.
Condo PEX Repair, Marina Peninsula
Before
A Marina Peninsula condo owner had a slow PEX leak that the HOA wanted documented before any under-slab work. The unit showed a musty smell near the hallway wall and a moisture meter reading that was off the chart. We mapped the PEX run and confirmed the leak with thermal imaging.
After
We submitted the detection report, got HOA approval the same week, and repaired the failed section in under three hours. The pressure test held at 100 PSI, the wall cavity dried out over four days, and the musty smell cleared. The board received the full test documentation.
Problems we solve
PEX Slab Leak Problems We Solve in Venice
PEX leaks under a slab do not announce themselves the way a burst supply line does. They show up as high bills, warm floors, and damp baseboards. Here is what we fix, and what happens if you wait.
Ask a pro →↗
Warm spot on the floor or tile
We confirm the hot line with a thermal imaging camera, expose the failed fitting, and replace it with new PEX. After a 100 PSI pressure test, we patch the slab and reset your flooring.
Sound of running water when everything is off
Our acoustic leak detection microphone pinpoints the sound to within a few inches. We cut one small access point, repair the line, and verify the fix with a pressure test before closing the slab.
Damp baseboards or musty smell near a wall
We find the source with a moisture meter and thermal camera, repair the PEX line, and dry-test the area. If the wall cavity is wet, we tell you exactly what needs to dry before we patch.

What PEX Slab Leak Repair Costs
$650 - $1,850 for most single-line PEX slab leak repairs in Venice
Typical 2026 pricing for PEX Pipe Slab Leak Repair in Venice runs $650 to $1,850 for a single-line repair, including detection, access, repair, pressure test, and concrete patch. Two-line repairs, tile matching, and rerouting push the number higher. We give you a flat price before we cut concrete, and it does not move unless you approve added scope. No hourly meter, no surprise line items.
You are paying for detection precision, a code-correct repair, a verified 100 PSI pressure test, and a matched concrete patch, all in one visit. That combination is what keeps the repair from failing again and what protects your floor, your foundation, and your resale paperwork.
01Number of leaking lines
A single failed PEX fitting is the simplest job. If the hot and cold lines both leak, or a second branch has failed, expect the price to climb. We test the whole system so we find every leak in one visit, not one per call.
02Access difficulty
Slabs under tile, engineered wood, or in tight condo hallways take longer to open and restore. We protect the surrounding flooring and size the cut to the repair, but difficult access adds labor and patch time.
03Repair versus reroute
A spot repair is the lower-cost option. If the PEX run has failed more than once, rerouting through the attic or walls can be more durable and sometimes cheaper long-term. We price both so you can compare.
04Concrete patch and finish
A standard matched patch is included. If you want tile matched to an older dye lot or a specific finish, that is a separate material cost. We tell you the number before ordering anything.

What Venice Neighbors Say
★★★★★
“Our water bill doubled in one month and the kitchen tile felt warm. Venice Slab Leak Pros found the PEX hot line leak in about 40 minutes with their acoustic gear. They cut one small square, replaced the fitting, pressure-tested it in front of me, and patched the floor the same afternoon. No drama, no surprise cost.”

★★★★★
“I called at 11 p.m. with water coming up through the garage slab. They answered, talked me through shutting the main, and had a tech here in about 75 minutes. The PEX line had a failed crimp ring. Repair was done by 2 a.m. and they came back the next day to pour the patch. Fair price for a middle-of-the-night call.”
MT
Marcus T.Homeowner, South Venice
✓ Verified★★★★★
“Our HOA needed documentation before approving anything under the slab. The team mapped the PEX run, showed the thermal images, and gave us a written scope. The repair itself took under three hours. They even sent the pressure test results to the board. That made the whole approval process painless.”

Elaine P.Condo Owner, Marina Peninsula
✓ VerifiedMost single-line PEX slab leak repairs in Venice run $650 to $1,850 in 2026, including detection, access, repair, pressure test, and concrete patch. Cost climbs if the leak sits under tile you want matched, if two lines failed, or if the run needs rerouting instead of a spot repair. We give you the number before we cut anything.
In Venice, the usual culprits are failed crimp rings, nicked pipe from original construction, and slab movement from our sandy, shifting soil. PEX itself is tough, but brass fittings and crimp connections corrode and loosen over time. High water table pressure and hot summer ground temperatures speed that up. Most failures we see are at fittings, not mid-pipe.
Sometimes, yes. If the leak is in an accessible section or the line can be rerouted through the attic or walls, we avoid the slab entirely. When the failure is mid-slab, we cut one small access point, usually under 14 inches square, rather than trenching the floor. We tell you which route fits your home after detection.
We do. Venice Slab Leak Pros handles PEX pipe slab leak repair across Venice, North Venice, South Venice, and Venice Gardens, with 24/7 emergency response. Call (941) 393-1086 and we will triage the problem on the phone, then dispatch a licensed technician with detection gear. Average arrival inside city limits is 60 to 90 minutes.
