Slab Leak Detection in Pontaic is how you find a water leak under your concrete floor before it wrecks the foundation. We use acoustic listening gear, thermal imaging cameras, and pressure testing to pinpoint the break within inches. If your water bill jumped and your floor feels warm, call Leak Fix Pros. We serve homeowners and businesses across Pontaic, Michigan, 24/7.
Slab Leak Detection in Pontaic is the process of finding water leaks in the pipes that run beneath your home's concrete foundation. We pressurize the system, listen for the escape with acoustic leak detection equipment, and scan the floor with a thermal imaging camera to map temperature changes. A pipe locator traces the line, and a moisture meter confirms the wet zone. Most jobs take two to four hours, and we mark the exact break point on the slab so repair crews cut only where they need to.
Pontaic homes built before 1980 often still have copper pipe under the slab, and that copper has been sitting in Michigan's freeze-thaw cycle for decades. When a homeowner searches for slab leak detection in Pontiac Michigan near me, the story is usually the same: a water bill that doubled, a warm spot on the kitchen floor, or the sound of running water when every fixture is off. We also handle slab leak repair Pontiac Michigan jobs where the line has already failed and the floor is starting to shift.
Every detection call covers the full diagnostic sequence, not a quick listen and a guess. You get the pressure test, the acoustic scan, the thermal image, the line trace, and a written report with the leak marked on your floor. Repair is quoted separately so you can decide on your own timeline.
We isolate the domestic water line and pressurize it with a calibrated pressure testing kit. A dropping gauge confirms an under-slab leak and rules out fixtures, toilets, and water heater connections. This step alone saves customers from paying for slab work when the real problem is a $12 flapper.
Using acoustic leak detection equipment from Sewerin and Gutermann, we listen to the pipe through the concrete. The microphone picks up the distinct hiss of pressurized water escaping a pinhole. We walk the floor in a grid pattern and log the loudest point, usually within two inches of the break.
A thermal imaging camera from Fluke shows the temperature difference where hot water is bleeding into the slab. On cold-water leaks we use it to spot the cool streak instead. The image is saved and included in your report, so you have visual proof of the leak location.
A pipe locator follows the exact path of the copper pipe, PEX tubing, or PVC pipe under the slab. Knowing the route tells the repair crew where to cut and where to avoid post-tension cables. We mark the path on the floor with tape before we leave.
You get a one-page report listing the leak location, pipe material, pipe diameter, and two repair options with pricing. Photos of the thermal image and the marked floor are attached. This is the document your insurance adjuster will ask for if you file a claim.
If you want us to handle the fix, we quote spot repair or reroute before we leave the driveway. Spot repair opens a small section of slab and replaces the failed pipe. Reroute abandons the under-slab line and runs new PEX through the attic or walls, which avoids future slab work entirely.
We ask three questions: has your water bill jumped, is there a warm spot on the floor, and do you hear running water with everything off? Your answers tell us whether this is a slab leak, a toilet leak, or a water heater leak. We book a same-day window and tell you what to expect.
On arrival, we isolate the domestic water line and pressurize it with a pressure testing kit. If the gauge drops, we know the leak is under the slab and not in a wall or fixture. This step takes about 20 minutes and rules out the cheap fixes first.
We walk the floor with acoustic leak detection equipment and a thermal imaging camera. The microphone picks up the hiss of escaping water; the camera shows the warm streak where hot water is bleeding into the concrete. Together they narrow the search to a two-foot zone.
A pipe locator traces the exact path of the copper pipe or PEX tubing under the slab. We mark the break point on the floor with tape and photograph it. You see the evidence before anyone picks up a hammer.
We hand you a one-page report with the leak location, the pipe material, and two repair paths: spot repair or reroute. You decide which fits your budget. If you want us to handle the repair, we schedule it before we leave the driveway.
Purpose-built equipment, used by trained technicians — so the job is done accurately the first time.
Listens to the sound of pressurized water escaping a pipe through concrete. We use Sewerin and Gutermann units because they filter out traffic and HVAC noise, which matters on busy Pontiac streets.
A Fluke camera shows the temperature difference where hot or cold water is bleeding into the slab. It gives us a visual map of the leak zone and a photo for your report.
Isolates the domestic water line and pressurizes it to confirm the leak is under the slab. A dropping gauge is the first hard evidence we get, and it rules out fixtures and water heater leaks.
Traces the exact path of copper pipe, PEX tubing, or PVC pipe under the slab. Knowing the route keeps the repair cut small and avoids post-tension cables.
A General Tools meter confirms the wet zone on the floor surface and helps us track how far moisture has spread. We use it before and after repair to verify the slab is drying.
A RIDGID camera lets us look inside the line when we suspect root intrusion or a collapsed section. It confirms pipe condition before we recommend spot repair or reroute.
A handheld electronic detector picks up moisture signatures in tight spots where a camera cannot reach. It is a fast second check on our acoustic findings.
A homeowner in Downtown Pontiac had a warm spot on the kitchen tile and a water bill that jumped from $75 to $260 in one month. Two other plumbers had guessed at the location and wanted to open the whole floor.
We pressure tested the line, found the leak with acoustic gear, and confirmed it with thermal imaging within two inches. The repair crew cut a single 14-inch access hole, replaced the failed copper section, and pressure tested the line to 80 psi. The bill returned to $78 the next cycle.
A landlord near Pontiac Central had a tenant complaining about damp carpet and a musty smell along an exterior wall. The cause was unclear, and the insurance company wanted proof before approving a claim.
We isolated the line, confirmed an under-slab leak with pressure testing, and marked the location with a thermal image and photos. The written report went straight to the adjuster. Repair was done in two days, and the claim was approved without a second inspection.
A restaurant owner in Downtown Pontiac heard water running under the dining room floor during off-hours. A shutdown during business hours would have cost thousands in lost covers.
We scheduled an after-hours detection call, traced the line with a pipe locator, and marked the leak before midnight. The repair crew opened a small section of slab, replaced the failed pipe, and pressure tested the line. The restaurant opened on time the next morning.
Every slab leak shows up differently. Some announce themselves with a water bill spike; others stay silent until the floor cracks. Here are the four problems we get called for most often in Pontaic.
Ask a pro →We pressure test the domestic line to confirm the leak is under the slab, then use acoustic and thermal gear to pinpoint it. Most customers get the leak isolated and the repair scheduled the same day, which stops the loss at the source.
Our thermal imaging camera maps the warm streak and confirms the break location within inches. We mark the spot, quote the repair, and typically have the line fixed within 48 hours so the floor can dry out before damage spreads.
We isolate the line, listen with acoustic equipment, and trace the pipe with a locator. If the leak is active, we treat it as an emergency and can shut the line down the same visit to stop the water loss.
We find the leak fast, stop the water, and give you a report you can hand to a foundation contractor if the slab has already moved. Catching it at the crack stage keeps the repair in the hundreds, not the tens of thousands.
$250 - $550 for standard residential detection; $450 - $900 for emergency or large commercial calls
Typical 2026 pricing for slab leak detection in Pontaic runs $250 to $550 for a standard residential call. That covers the pressure test, acoustic scan, thermal imaging, pipe trace, and written report. Emergency and after-hours calls run higher, and larger commercial slabs take longer to scan. If you book the repair with us, we credit part of the detection fee toward the work. You get the flat rate before we dispatch, so there is no hourly meter running while we work.
A detection call costs a fraction of what a foundation repair runs. Finding the leak on the first visit keeps the repair cut small, stops the water loss the same day, and gives you a documented report for insurance. That is the difference between a $400 problem and a $12,000 one.
A 1,200-square-foot ranch takes about two hours to scan. A 3,000-square-foot home with multiple wet walls can take four hours or more. Larger slabs mean more grid points and more time with the acoustic gear.
Homes with irrigation systems, pool lines, or separate hot and cold runs take longer to isolate. Each zone needs its own pressure test before we can confirm which line is leaking.
Standard business-hour calls are the base rate. Nights, weekends, and holidays carry an emergency premium because we roll a truck outside normal hours. Active leaks get priority routing.
Tile, hardwood, and thick carpet all affect how well acoustic gear reads through the floor. We adjust our method and sometimes use tracer gas on floors that muffle sound.
Most slab leak detection jobs in Pontiac run $250 to $550 in 2026, depending on home size and how many lines we need to isolate. That covers the pressure test, acoustic scan, thermal imaging, and a written report with the marked leak location. Emergency and after-hours calls carry a higher rate. If you book the repair with us, we credit part of the detection fee toward the work.
The four signs we see most: a water bill that jumps 30 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 in the floor or baseboards. Damp carpet and a musty smell near an exterior wall also point to an under-slab leak. Any two of these together justify a detection call.
Yes. Acoustic leak detection equipment hears the water escaping the pipe through the concrete, and a thermal imaging camera shows the temperature change on the floor surface. We combine both with pressure testing and a pipe locator to confirm the exact spot. We routinely pinpoint leaks within two inches on a 4-inch slab, which is why the repair cut stays small.
Many Michigan homeowner policies cover the water damage from a slab leak and the access needed to reach the pipe, but not the pipe repair itself. Detection is often reimbursable when it is part of a covered loss. We provide an itemized report with photos and the marked location, which is the documentation adjusters ask for. Call your carrier before the repair and ask what your policy covers.
