Electronic Slab Leak Detection Venice FL is a non-invasive diagnostic service that locates a pressurized water line leak beneath your concrete slab using acoustic listening equipment, thermal imaging, and pressure testing. We pressurize the line, walk the slab with a microphone tuned to the frequency of escaping water, then confirm the exact spot with a thermal imaging camera. Most homes take 90 minutes to three hours to diagnose. You get a marked location on the floor and a written finding before anyone picks up a hammer.
Venice sits on sandy soil and a high water table, and the older housing stock around Venice Gardens and South Venice still runs a lot of copper pipe and polybutylene pipe under the slab. Both fail over time. Copper pipe corrosion from aggressive soil eats pinholes through the wall, and polybutylene pipe failure shows up as sudden splits. That is why so many neighbors search for electronic slab leak finding Venice FL after a water bill doubles. We see hot water line slab leak calls spike every winter.
Every electronic detection call in Venice includes the full diagnostic package below. If we cannot locate the leak, you do not pay for the search. Repair work is quoted separately and flat, so you always know the number before we cut.
We isolate your domestic water system and watch a pressure testing gauge for 15 to 20 minutes. A dropping gauge confirms a supply-side leak under the slab. This step tells us whether we are chasing a hot line, a cold line, or a drain issue before we spend time listening.
We grid your slab and walk it with a Sewerin or Gutermann acoustic microphone, listening for the frequency of pressurized water escaping a pipe. On a typical 1,800-square-foot Venice home this takes 30 to 45 minutes and narrows the leak to a small zone.
A Fluke thermal imaging camera and infrared thermometer confirm the hot spot. On a hot water line slab leak the signature is 8 to 12 degrees warmer than surrounding concrete. On cold lines we verify with a moisture meter instead.
We mark the leak with paint and show you the readings on the screen. You see exactly where we plan to cut before we cut. That transparency is why homeowners trust the finding and why our access cuts stay small.
You get a written summary of the diagnosis and a flat price to open the slab and repair the line. No hourly meter, no surprise line items. You decide on the spot whether to proceed, and we schedule the repair around your day.
You call (941) 393-1086 and describe what you are seeing: high bill, warm floor, sound of running water. We ask a few questions to narrow whether it is a hot water line slab leak or a cold line. Takes five minutes. We book a same-day or next-morning window that fits your schedule.
On arrival we isolate the domestic water system and hook up a pressure testing gauge. If the gauge drops with everything shut off, you have a confirmed leak under the slab. This step takes 15 to 20 minutes and tells us whether we are chasing a supply line or a drain issue.
We walk the slab with an acoustic leak detection microphone, listening for the hiss of pressurized water escaping a pipe. We grid the floor and mark the loudest points. On a 1,800-square-foot Venice home this sweep runs 30 to 45 minutes and narrows the leak to a small zone.
A thermal imaging camera and infrared thermometer confirm the hot spot. On a hot water line slab leak the thermal signature is obvious, often 8 to 12 degrees warmer than surrounding concrete. On cold lines we use a moisture meter to verify. Two tools agreeing means we are standing on the leak.
We mark the spot with paint, show you the reading, and hand you a flat price to open the slab and repair the line. You decide on the spot. If you approve, we cut a small access, fix the pipe, pressure test again, and patch the concrete before we leave.
Purpose-built equipment, used by trained technicians — so the job is done accurately the first time.
Listens through concrete for the frequency of pressurized water escaping a pipe. It is the primary tool for locating copper pipe and PEX pipe leaks under a slab.
Spots temperature differences on the slab surface. Fastest confirmation tool for a hot water line slab leak, where the signature is 8 to 12 degrees warmer than surrounding concrete.
Isolates the domestic water system and watches for pressure drop. Confirms a supply-side leak in 15 to 20 minutes before we spend time listening.
Checks pipe condition inside the run once we open the slab. Helps us decide between a spot repair, epoxy pipe lining, or a full section replacement.
Verifies cold water line leaks where thermal signature is weak. Also checks baseboards and drywall for wicking moisture after a long-running leak.
Maps the path of under-slab lines so we know where the pipe runs before we cut. Keeps the access opening small and avoids nicking a neighboring line.
A homeowner in Venice Gardens noticed a $120 jump in the water bill and a faint hiss near the hallway. The slab was original 1978 construction with copper pipe. We pressure tested and confirmed a supply leak, then located a pinhole within 10 inches using the acoustic microphone.
We opened a 2-foot by 2-foot access, replaced the corroded section with new copper and code-correct fittings, and pressure tested at working pressure. The concrete patch cured flush with the surrounding slab. The next water bill dropped back to normal.
A condo owner in Marina Peninsula felt warm tile in the bathroom and the water heater ran constantly. The HOA required documentation before any slab work. We confirmed a hot water line slab leak with thermal imaging, showing a 10-degree difference on the camera.
We provided a written finding the HOA accepted, then opened a small access and repaired the line. The pressure held overnight. The water heater stopped running nonstop, and the warm spot faded within two days as the slab dried.
A South Venice homeowner heard water running under the floor overnight and called at 7 a.m. The home had original polybutylene pipe. We pressure tested, confirmed a supply leak, and located a split in the line with the acoustic microphone within two hours of arrival.
Rather than patch failing polybutylene, we rerouted the line overhead through the attic. No additional slab cut beyond the initial access. The pressure test held, the floor stayed dry, and the water bill returned to normal the following month.
Most slab leaks announce themselves one of four ways: a high water bill, a warm floor, the sound of running water, or a crack in the tile. Here is what we do about each.
Ask a pro →We pressure test first to confirm a supply-side leak, then sweep the slab with an acoustic microphone and thermal camera. Most Venice calls like this are located within two hours. We mark the spot, quote the repair flat, and fix it the same day when you approve.
Thermal imaging confirms a hot water line slab leak fast because the signature is strong. We locate the break, open a small access, and repair the line with code-correct fittings. Then we pressure test and patch the concrete before we leave.
We isolate the system with a pressure testing gauge, then listen with an acoustic leak detection microphone to pinpoint the break. Copper pipe corrosion and polybutylene pipe failure are the usual culprits in older Venice homes. We repair or reroute the line and test it before patching.
We locate the leak electronically, stop the source, and let the slab dry before any tile work. In many Venice homes the tile can be reset after the patch cures. Catching it early with electronic slab leak detection near me Venice calls is what keeps the repair small.
$250 - $1,800 depending on scope
Typical 2026 pricing in this area runs $250 to $450 for the electronic detection visit, depending on slab size and how many lines we test. The repair is quoted separately and flat, usually $650 to $1,800 for a standard under-slab line fix and concrete patch. Rerouting a line overhead costs more upfront but avoids a slab cut. We give you both numbers before we start, and if we cannot find the leak, you do not pay for the search.
You are paying for accuracy. A blind cut can cost three times as much in concrete, tile, and time. Electronic detection narrows the leak to about a square foot, so the repair stays small and your floor stays intact.
A larger slab takes longer to sweep with the acoustic microphone. A 3,000-square-foot home can take twice as long as a 1,500-square-foot condo. Tight access in a condo or townhouse also adds time because we have less room to work.
Copper pipe and PEX pipe are straightforward to repair. Polybutylene pipe failure often means replacing a longer section or rerouting, which raises the cost. We tell you which material you have after the diagnosis.
Hot water line slab leaks are faster to confirm because the thermal signature is strong. Cold water line leaks take longer to locate and sometimes need a second pass with the moisture meter. That can add an hour to the visit.
A small 2-foot by 2-foot patch is standard. If the leak sits under tile, we may need to lift and reset a few tiles. Larger access or a post-tension slab adds cost because the repair has to be engineered correctly.
“Our water bill jumped $90 in one month and we could not find why. The tech pressure tested, walked the slab with the microphone, and marked the spot in under two hours. It was a pinhole in the copper under the hallway. They cut a two-foot square, fixed it, and patched it the same day. No mess left behind.”
Dana R.Homeowner, Venice Gardens
✓ Verified“Warm tile in the bathroom had me worried about a hot water line leak. They confirmed it with the thermal camera and showed me the reading on the screen. The HOA needed documentation, and they provided it without me asking twice. Repair was done in one visit and the pressure held overnight.”
Miguel S.Condo Owner, Marina Peninsula
✓ Verified“I called at 7 a.m. after hearing water running under the floor all night. They had a truck at the house by 9. Electronic detection found a split in the old polybutylene line. They rerouted it overhead instead of cutting more slab, which I appreciated. Dry floor, lower bill, done in a day.”
Karen T.Homeowner, South Venice
✓ VerifiedWe pressurize your water line, then listen through the slab with an acoustic microphone tuned to the sound of escaping water. A thermal imaging camera confirms the hot spot on hot lines, and a moisture meter verifies cold lines. Two tools agreeing pinpoints the leak within about a foot. The whole diagnosis takes 90 minutes to three hours, and you get a marked spot on the floor before we cut anything.
Most electronic slab leak detection calls in Venice run $250 to $450 for the diagnosis, depending on slab size and how many lines we test. The repair is quoted separately and flat, usually $650 to $1,800 for a typical under-slab line fix and concrete patch. We give you both numbers before we start. No surprise line items on the invoice.
Yes. Acoustic and thermal detection together locate a pressurized slab leak within about 12 inches in most homes. Accuracy drops slightly on very deep slabs or when a drain line is also leaking, which is why we pressure test first to confirm it is a supply line. On copper pipe and PEX pipe systems we routinely hit the leak on the first access cut.

Slab Leak DetectionOur full slab leak detection service combines electronic listening, thermal imaging, and pressure testing to find any under-slab leak. It is the parent service behind every electronic call we run in Venice, and it covers hot lines, cold lines, and drain issues under the concrete.Explore →
Under-Slab Water Leak RepairOnce electronic detection marks the spot, under-slab water leak repair opens a small access, fixes the line, and patches the concrete. We pressure test before and after. Most Venice repairs are done in a single day with a 2-foot by 2-foot access cut.Explore →
Hot Water Line Slab Leak RepairA hot water line slab leak shows up as a warm spot on the floor and a spinning meter. Electronic detection confirms it fast because the thermal signature is strong. We repair the line, re-test, and patch. These calls spike in Venice every winter when heating demand rises.Explore →
Cold Water Line Slab Leak RepairCold line leaks are quieter and harder to hear, so we lean on acoustic microphones and moisture meters. Electronic detection narrows the break, then we open the slab and repair the cold water line. You get a dry slab and a tested line before we leave.Explore →
Copper Pipe Slab Leak RepairVenice soil is aggressive on copper pipe, and pinhole corrosion is common in older homes. Electronic detection finds the pinhole, and we repair or replace the section with code-correct fittings. We check the rest of the run for thinning while the slab is open.Explore →
PEX Pipe Slab Leak RepairPEX pipe systems fail at fittings and crimp joints more than along the run. Electronic detection locates the break, and we repair with Uponor or SharkBite fittings rated for under-slab use. We pressure test at full working pressure before patching.Explore →
Polybutylene Pipe Slab Leak RepairPolybutylene pipe failure is a known problem in Venice Gardens and other 1970s and 1980s neighborhoods. Electronic detection finds the split, and we often recommend rerouting or replacing the run rather than patching a failing material. We walk you through the options.Explore →
Concrete Slab Leak DetectionConcrete slab leak detection is the broader category that includes electronic, acoustic, and thermal methods. We choose the right combination based on your slab thickness, pipe material, and whether the leak is on a hot or cold line. Most Venice slabs get all three.Explore →A spinning meter or a warm floor will not fix itself. We are licensed, insured, and we answer 24/7 across Sarasota County.
