Service overview
What PEX Pipe Leaks Under Slabs Olathe KS actually means
PEX Pipe Leaks Under Slabs Olathe KS is a leak repair service that finds and fixes failures in cross-linked polyethylene water lines running beneath a concrete floor. PEX has replaced copper in most homes built since the mid-1990s, and it usually holds up well. But fittings, crimp rings, and abrasion points can fail. When they do, water travels through the slab and shows up as a warm spot, a damp carpet edge, or a water bill that jumps $40 to $120 in a single month. In Olathe, we see this most in homes built between 1995 and 2015, where PEX was run through or under the slab during original construction. Johnson County's clay soils shift with our wet springs and dry summers, and that movement stresses lines at the point they enter the slab. If you have been typing PEX pipe leaks under slabs near me Olathe KS into your phone, the leak is probably already reaching your flooring. We stop it before the damage spreads.
! Common warning signs
Water bill jumped $40 to $120 with no change in usage
A failed PEX line can waste thousands of gallons a month. Ignoring it means paying for water that is soaking into the soil under your foundation.
Warm spot on the floor that keeps getting bigger
A warm spot usually means a hot water PEX line is leaking under the slab. The heat spreads through the concrete and can warp hardwood or loosen tile over time.
Damp carpet or baseboards along an interior wall
Water from a PEX leak wicks upward through the slab and into flooring. Left alone, it can cause mold, delaminated flooring, and damage that costs far more than the repair.
Scope of work
What our PEX Pipe Leaks Under Slabs service includes
Every PEX slab leak job starts with detection and ends with a pressure test. Here is what is included in a standard repair, and what we handle as an add-on when the situation calls for it.
-
01
Leak detection and marking
We pressure test the system, sweep the slab with acoustic listening discs, and confirm with a thermal imaging camera. The leak location is marked on your floor before we cut. This is included in every job.
-
02
Targeted concrete opening
We cut a 12 to 24 inch access opening with a concrete saw and break out only the slab over the leak. Dust control and floor protection are included. We do not trench across the room.
-
03
PEX repair with matching fittings
We remove the damaged section and install new PEX with Uponor or SharkBite fittings matched to your existing line. The repaired run is insulated where it passes through the slab.
-
04
Pressure test and concrete patch
Every repair is pressure tested at 80 to 100 PSI for 30 to 60 minutes. Once it holds, we backfill, pour concrete patch, and finish with self-leveling compound where needed. Cleanup is included.
Why Olathe homeowners call us for PEX slab leaks
A slab leak never fixes itself, and the longer water runs under your floor, the more it costs. Here is what changes when you call us instead of waiting another month.
Schedule a visitTools and methods we use for PEX slab leaks
FLIR thermal imaging camera
We use it to scan the floor surface for temperature differences. Hot water PEX leaks show up as warm streaks, which helps us mark the repair area before we cut.
Acoustic listening disc and Sewerin equipment
These pick up the sound of pressurized water escaping a PEX line. We use them to narrow the leak location to within a few inches on most Olathe slabs.
RIDGID and General Pipe Cleaners inspection cameras
When the leak is near a drain or sewer line, we run a video pipe inspection camera to rule out a sewer leak under the slab before we commit to a repair plan.
Milwaukee and DeWalt concrete saws
We use these to cut clean, measured access openings in the slab. A controlled cut means less dust, less vibration, and a patch that fits the first time.
Local execution
Olathe sits on Johnson County clay, and that soil moves with our wet springs and dry summers. That movement stresses PEX lines where they enter the slab, and it is why we see so many failures in homes built between 1995 and 2015. Our freeze-thaw cycles are milder than western Kansas, but a hard freeze can still split a line in an unheated crawlspace or garage wall. When we repair a PEX line under a slab here, we account for that movement by leaving a small amount of slack at the entry point and insulating the repaired run. We also follow Johnson County Plumbing Permit requirements, which means pressure testing and inspection documentation on jobs that need it. If you are comparing PEX slab leak repair cost Olathe Kansas across companies, ask whether detection and pressure testing are included. On most of our jobs they are, and that keeps you from paying twice if the first repair does not hold.

How our PEX slab leak repair process works
Phone triage
You call (913) 358-1454 and describe what you are seeing: warm spots, a spinning meter, a damp patch. We ask a few questions to rule out a toilet flapper or irrigation leak, then schedule a visit. Most Olathe addresses get a same-day or next-morning appointment.
Detection and confirmation
On site, we isolate the water system and run a pressure test. If pressure drops, we sweep the slab with acoustic listening discs and a FLIR thermal camera. We mark the leak location on your floor with tape so you can see exactly where the problem is before we cut.
Targeted concrete opening
We cut a small access opening with a concrete saw and break out the slab only over the marked area. Most openings are 12 to 24 inches square. You will see the failed PEX line, the wet soil, and the fitting that gave out. No surprises, no hidden charges.
What PEX slab leak repair costs in Olathe
Typical 2026 pricing in Olathe runs $650 to $2,400 for detection, repair, and concrete patching. The low end covers a straightforward leak in an accessible area with a short damaged section. The high end covers deeper lines, longer repairs, or jobs that require pulling back flooring. We give you a flat quote before we start, so the invoice matches the number you approved. If you are comparing PEX slab leak repair Olathe KS pricing, ask whether detection and pressure testing are included. On our jobs, they are.
Depth of the PEX line
Lines buried deeper in the slab take longer to access and require more concrete removal. A line 4 inches down is a faster repair than one 8 inches down. We confirm depth during detection so the quote reflects it.
Length of damaged section
A failed fitting is a small repair. A section of PEX that has been abraded over several feet requires more new material and a longer opening. We measure the damaged run before quoting.
Flooring and access
Tile, hardwood, and engineered flooring have to be pulled back carefully and may need a flooring contractor to reinstall. Carpet and vinyl are faster to move. We tell you upfront if flooring work is outside our scope.

Frequently asked questions
How do you repair PEX pipe leaks under a slab in Olathe KS?
We locate the leak with acoustic and thermal detection, cut a small access opening in the slab, remove the damaged PEX section, and install new PEX with matching fittings. Then we pressure test at 80 to 100 PSI and patch the concrete. Most repairs are completed in one day.
What causes PEX pipe leaks under slabs in Olathe?
The most common causes are failed crimp fittings, abrasion where the PEX rubs against rebar or gravel, and soil movement from Johnson County's clay. Heat cycling on hot water lines also weakens fittings over time. In Olathe, we see the most failures in homes built between 1995 and 2015.
How much does PEX pipe slab leak repair cost in Olathe?
Typical 2026 pricing in Olathe runs $650 to $2,400 for detection, repair, and concrete patching. Cost depends on how deep the line sits, how long the damaged section is, and whether the floor covering needs to be pulled back. We give you a flat quote before we start.
Can PEX pipe leaks under slabs be repaired without breaking concrete in Olathe?
Sometimes. If the leak is in a line that can be rerouted through the attic or walls, we can abandon the under-slab section and run new PEX above. That avoids concrete work entirely. We evaluate both options on site and recommend the one that costs less and lasts longer.
