Concrete Slab Leak Access and Repair Venice FL is the trade of finding a pressurized water line leak buried beneath your foundation, opening the slab at the exact spot, and restoring the pipe and concrete. We start with acoustic leak detection microphone work and a thermal imaging camera to hear and see where water is escaping. Once we mark the line, we cut a small access opening, repair the copper pipe or PEX pipe, pressure-test it, and pour a concrete patch that matches the surrounding floor.
Most Venice homes sit on slab-on-grade construction, and the combination of sandy soil, high water tables, and aggressive Florida heat puts constant stress on under-slab plumbing. A hidden slab leak can run for weeks before you notice a spike in your water bill or a hot spot on the tile. We get calls from Venice Gardens, South Venice, and North Venice homeowners who hear water running when every fixture is off. That is the moment to call a professional concrete slab leak access and repair service Venice FL trusts.
Every job starts with detection and ends with a pressure-tested, patched slab. Here is what is covered when you hire us for concrete slab leak access and repair in Venice.
We use acoustic and thermal equipment to find the leak and mark the exact spot on your floor. This step is included in every job because it determines where we cut. Accurate marking keeps the access opening small and the repair cost down.
We cut a clean opening with a wet saw to control dust, usually 18 to 24 inches square. We lay drop cloths and plastic sheeting to protect your floors and furniture. The cut is sized to give us room to work without removing more concrete than necessary.
We cut out the failed section of copper, PEX, or polybutylene pipe and replace it with new material. We use SharkBite, Uponor, and Mueller fittings. The repair is code-correct and rated for decades of service under your slab.
We isolate the repaired line and pressurize it to 80 psi for 30 minutes. If the gauge holds, the repair is good. If it drops, we keep working. We never close a slab on a line that has not passed a pressure test.
We backfill with sand, pour a concrete patch, and finish it level with the surrounding floor. We clean up all dust and debris before we leave. You can walk on the patch in 24 hours and put furniture back in 48.
Every repair comes with a written warranty on parts and labor. We also give you a photo record of the work so you know exactly what was done under your slab. If anything looks off, you call us and we come back.
We ask three questions: is water running with all fixtures off, is the floor warm or wet, and has your water bill jumped. Your answers tell us whether this is a hot water line slab leak or a cold water line slab leak. We book a same-day visit and give you a price range before we hang up.
Our technician walks the slab with an acoustic leak detection microphone and a thermal imaging camera. We listen for the hiss of pressurized water and look for temperature anomalies in the floor. This step takes 45 to 90 minutes and tells us the exact X and Y coordinates of the leak.
We mark the spot, lay drop cloths, and cut a clean access opening with a wet saw. Once we expose the pipe, we confirm the failure, cut out the damaged section, and repair it with copper or PEX. Most repairs take two to four hours from cut to pressure test.
We pressurize the repaired line to 80 psi and hold it for 30 minutes. If it holds, we backfill with sand, pour a concrete patch, and finish it level with the surrounding floor. You can walk on the patch in 24 hours and put furniture back in 48.
Before we leave, we run every fixture in the house, check the water meter for movement, and show you the repair. We hand you a written warranty and a photo record of the work. If anything looks off in the next 30 days, you call us and we come back.
Purpose-built equipment, used by trained technicians — so the job is done accurately the first time.
We place this microphone on the floor and listen for the sound of pressurized water escaping the pipe. The loudest reading is the leak. It works through 4 to 6 inches of concrete.
This camera shows temperature differences in the floor. Hot water leaks appear as warm spots. Cold water leaks appear as cool spots. We use it to cross-verify the acoustic reading.
We use this gauge to pressurize the repaired line to 80 psi and hold it for 30 minutes. If the pressure holds, the repair is good. If it drops, we keep working.
We cut the concrete access opening with a wet saw to control dust. The blade is rated for reinforced concrete. This tool lets us make a clean, square cut that is easy to patch.
For larger pipes, we run a video camera through the line to see the inside of the pipe. This helps us confirm the extent of corrosion or find a fitting that has failed.
We use these to check the moisture level in the concrete and the temperature of the floor. They help us confirm the leak location and verify the slab is dry before we patch.
A homeowner in Venice Gardens noticed a warm spot on the kitchen floor and a water bill that jumped from $60 to $180 per month. The home had original copper pipe under the slab. We used thermal imaging to find the leak and acoustic detection to confirm it.
We cut a 20-inch access opening, replaced 18 inches of corroded copper pipe, and pressure-tested the line at 80 psi. The repair held. The water bill returned to normal the next month. The concrete patch is level and barely visible.
A South Venice homeowner heard water running at night when everything was off. The water meter showed a constant flow. We used an acoustic microphone to locate the leak under the living room slab. The pipe was PEX with a failed crimp fitting.
We cut a 16-inch access opening, replaced the failed fitting with a SharkBite connection, and pressure-tested the line. The repair took three hours. The water meter stopped moving immediately. We patched the slab and cleaned up the same day.
A Venice Beach condo owner had water seeping into the unit below. The building had polybutylene pipe from the 1980s. We used thermal imaging to trace the leak to a failed section of gray pipe under the bathroom slab. The HOA needed documentation before we could cut.
We documented the leak with photos, coordinated with the HOA, and replaced 12 feet of polybutylene pipe with PEX. We pressure-tested the new line at 80 psi and patched the slab. The HOA signed off the same week. No more water in the unit below.
A slab leak shows up in different ways depending on the pipe and the house. Here are the problems we see most often and how we fix them.
Ask a pro →We use acoustic and thermal detection to find the leak, then access the slab and repair the pipe. Most hidden slab leaks are fixed in a single day. We also check the water meter before and after to prove the leak is gone.
We locate the hot water line with thermal imaging, cut a small access opening, and repair the copper or PEX pipe. The floor returns to normal temperature within hours of the repair. We pressure-test the line before patching.
We shut down the line, find the leak with an acoustic leak detection microphone, and repair the pipe. If the line is too far gone, we reroute it through the attic or walls. You get a permanent fix, not a patch.
We find the leak, repair the pipe, and restore the slab. We also check the moisture level in the surrounding concrete to make sure the area is dry before we patch. In most cases the flooring can be repaired after the slab is fixed.
$650 - $2,400 depending on depth, pipe material, and access location
Typical 2026 pricing for concrete slab leak access and repair in Venice runs $650 to $2,400. The low end covers a straightforward copper pipe repair under a garage slab. The high end covers a deep access, a reroute, or a repair that requires more concrete removal. Detection alone is $250 to $450. We give you a written price before we start, and we do not add charges halfway through the job. If you are looking for affordable concrete slab leak access and repair Venice, Florida, call us for a phone estimate.
A slab leak does not get cheaper with time. The longer water runs under your foundation, the more damage it does to the soil and the slab. Fixing it now at $650 to $2,400 is far cheaper than a foundation repair that can run $10,000 or more.
The deeper the pipe sits below the slab, the more concrete we have to remove to reach it. A pipe 6 inches down is a quick cut. A pipe 18 inches down takes longer and requires more patch material. Depth is the biggest driver of cost.
Copper pipe repairs are straightforward. Polybutylene pipe is more fragile and may require a larger replacement section. PEX pipe is easy to repair but the fittings can be tricky. The material affects both the labor time and the parts cost.
A leak under a garage slab is easy to access. A leak under a finished floor in a living room or kitchen is more difficult because we have to protect the flooring and work in a tight space. Access location can add $200 to $600 to the job.
A spot repair is the cheapest option. A reroute through the attic or walls costs more upfront but avoids future leaks in the same pipe. We walk you through both options and give you a price for each before you decide.
“Our water bill doubled and we could not figure out why. Venice Slab Leak Pros came out, used a thermal camera, and found a hot water line slab leak in two hours. They cut a small square in the garage slab, fixed the copper pipe, and patched it the same day. You can barely see where they worked. Worth every penny.”
Maria G.Homeowner, Venice Gardens
✓ Verified“I called three plumbers and none of them wanted to touch a slab leak. These guys showed up the same afternoon, found the leak with an acoustic microphone, and gave me a written price before they started. The repair took about five hours. No surprises, no mess left behind. I will use them again.”
Dave R.Homeowner, South Venice
✓ Verified“A slab leak in a condo is a nightmare because of the HOA. Venice Slab Leak Pros handled the paperwork, documented everything with photos, and repaired the cold water line under the slab. They were in and out in one day and the HOA signed off without a problem. Highly recommend.”
Linda P.Condo Owner, Venice Beach
✓ VerifiedWe locate the leak with acoustic and thermal equipment, cut a small access opening in the slab, repair or replace the failed pipe section, pressure-test the line, and patch the concrete. Most jobs take four to eight hours from arrival to final patch. You can walk on the repaired floor within 24 hours.
Typical 2026 pricing in Venice runs $650 to $2,400 for access and repair, depending on depth, pipe material, and whether we reroute the line. Detection alone is $250 to $450. A straightforward copper pipe repair under a garage slab sits at the low end. A reroute through the attic or walls sits at the high end.
Yes. We cut the smallest opening that lets us reach the pipe, usually 18 to 24 inches square. In some cases we can reroute the line through the attic or walls and avoid cutting the slab entirely. We tell you which option makes sense after we see the layout and the leak location.

Slab Leak DetectionDetection always comes before access. We use acoustic microphones and thermal cameras to mark the leak so the access cut lands in the right spot. Without detection, you are guessing, and guessing means extra concrete removal and extra cost.Explore →
Under-Slab Water Leak RepairThis is the repair itself once we have access. We cut out the failed section of copper or PEX, install new pipe and fittings, and pressure-test the line. It is the core of what we do for Venice homeowners with hidden slab leaks.Explore →
Hot Water Line Slab Leak RepairHot water lines fail faster because heat accelerates corrosion. If your floor feels warm in one spot, that is a hot water line slab leak. We access the line, repair it, and restore the slab so you get hot water without the waste.Explore →
Cold Water Line Slab Leak RepairCold water leaks are quieter and often run longer before you notice. They show up as a rising water bill or a damp spot on the floor. We find the leak, open the slab, and repair the cold line with code-correct materials.Explore →
Copper Pipe Slab Leak RepairCopper pipe corrosion is the most common cause of slab leaks in older Venice homes. We cut out the pitted section and repair with new copper or transition to PEX. The repair is pressure-tested and warrantied.Explore →
PEX Pipe Slab Leak RepairPEX pipe is durable, but fittings and crimp rings can fail. When a PEX line leaks under the slab, we expose the fitting, replace it with a SharkBite or Uponor connection, and test the line before closing the slab.Explore →
Polybutylene Pipe Slab Leak RepairPolybutylene pipe failure is common in homes built between 1978 and 1995. The gray pipe becomes brittle and splits. We repair the immediate leak or reroute the entire line, depending on how much polybutylene is left in the slab.Explore →
