Service overview
What Under Slab Pipe Leak Repair Olathe KS Actually Involves
Under Slab Pipe Leak Repair Olathe KS is the process of locating a failing water or sewer line beneath your concrete foundation, exposing it through a small access point, and restoring the pipe so it holds pressure again. We start with acoustic leak detection equipment and a thermal imaging camera to pinpoint the break within a few inches. Then we cut a small opening with a concrete saw, repair or replace the damaged section, and patch the slab with concrete patch and self-leveling compound. Most jobs finish in one day. Olathe homeowners call us when a high water bill shows up out of nowhere or when warm spots on the floor point to a hot water line slab leak. Older neighborhoods near Downtown Olathe and Old Town Olathe have copper pipe that has been in the ground for decades, and copper pinholes are common after years of Johnson County's shifting clay soil. If you need under slab pipe leak repair in Olathe Kansas, we can usually be on site the same day.
! Common warning signs
Water bill jumped $80 or more with no change in use
A pinhole leak can waste 10,000 gallons a month and quietly soften the soil under your foundation. Left alone, that turns a pipe repair into a foundation repair.
Warm spot on the floor near a bathroom or kitchen
A warm patch means a hot water line slab leak is heating the concrete from below. It will not cool down on its own, and the leak grows as the pinhole widens.
Water pooling around the foundation or a musty smell indoors
Water finding its way to the surface means the leak has been running a while. You may already have damaged flooring, baseboards, or a wet subfloor under tile.

A full pressure test at 80 to 100 psi before closing, then backfill, concrete patch, and self-leveling compound to leave a smooth, walkable surface. You get a written warranty on the repair and a walkthrough before we pack up.
Why Olathe Homeowners Choose Our Under-Slab Leak Service
A slab leak does not fix itself, and waiting makes the damage worse. Here is what you get when you call us for under slab pipe leak repair in Olathe Kansas.
Book a visitTools and Methods We Use on Every Job
Sewerin Listening Disc and Acoustic Detection Equipment
Amplifies the sound of pressurized water escaping a pipe so we can narrow the leak to a small area before cutting concrete. It is the first tool on the slab for most Olathe calls.
FLIR Thermal Imaging Camera
Shows temperature differences on the floor surface. Hot water leaks appear as warm spots and cold leaks as cool streaks, confirming what acoustic detection finds and guiding the cut location.
RIDGID Video Pipe Inspection Camera
Lets us look inside drain and sewer lines to rule out a sewer pipe leak under concrete slab before we commit to a supply-line repair plan. Also used to verify repairs from the inside.
Milwaukee Concrete Saw and DeWalt Jackhammer
Cuts clean edges in the slab and removes the concrete section with controlled force. We check for post-tension cables first and set blade depth to avoid damaging the foundation structure.
Local execution
Olathe sits on Johnson County clay that expands when wet and shrinks when dry, and that movement is hard on buried pipe. Homes built before 1990 mostly have original copper under the slab, and copper pinholes are the number one leak we see. Newer neighborhoods like Cedar Creek and Stonebridge use PEX, which fails more often at fittings and abrasion points than in the pipe body. Our freeze-thaw swings in late fall and early spring put extra stress on lines that are already weakened. When you need sub slab plumbing leak repair Olathe KS, we start with detection, not demolition, because cutting the wrong spot costs you money and floor. If you are asking how to repair a pipe leak under concrete slab in Olathe, the honest answer is: locate it precisely, open a small section, repair the pipe, and pressure-test before you patch. We pull a Johnson County Plumbing Permit on permitted work and follow IAPMO Uniform Plumbing Code on every repair.

How Our Under-Slab Pipe Leak Repair Process Works
Call and Questions
You call (913) 358-1454 and describe what you are seeing: high bill, warm floor, sound of running water, or water pooling around the foundation. We ask a few quick questions, give you a rough range, and book a visit, often the same day. No charge for the phone conversation.
Locate the Leak
We arrive with acoustic leak detection equipment, a Sewerin listening disc, and a FLIR thermal imaging camera. By pressurizing the line and listening at the slab, we narrow the break to a spot usually smaller than a dinner plate. This step takes 45 to 90 minutes and saves you from exploratory demolition.
Confirm and Quote
We mark the spot, show you what we found, and give you a firm price before any concrete is cut. If the line is copper and the leak is isolated, we repair that section. If the pipe is failing in multiple places, we walk you through Slab Leak Pipe Rerouting as an alternative. You decide.
What Under-Slab Pipe Leak Repair Costs in Olathe
Typical 2026 pricing in Olathe runs $600 to $2,500 for a single-spot under slab pipe leak repair, including detection, the concrete cut and patch, and pressure testing. Rerouting a failing line instead of spot-repairing it usually runs $2,800 to $6,500. We quote a firm number before we cut, so you are never guessing. If you want a ballpark before we come out, call (913) 358-1454 and describe what you are seeing.
Slab thickness and finish
Standard 4-inch residential slabs are the easiest to open. Thicker slabs, post-tension slabs, and floors finished with tile or hardwood add labor because the finish has to be removed and reset. That can add $300 to $900 to the job.
Pipe material and access depth
Copper repairs are straightforward when the leak is isolated. PEX fittings are quick to replace. Deeper lines or leaks under cabinets and fixtures take longer to reach, which adds an hour or two of labor and a larger access opening.
Repair vs reroute
A single-spot repair is the lowest-cost option. If the line is failing in multiple places, rerouting through the attic or walls avoids repeated concrete cuts and usually costs less over five years, even though the upfront number is higher.

Frequently Asked Questions
How do you repair a pipe leak under a concrete slab in Olathe KS?
We locate the leak with acoustic and thermal tools, cut a small access opening in the slab, expose the pipe, and repair or replace the damaged section. Then we pressure-test the line at 80 to 100 psi, backfill, and patch the concrete. Most repairs are finished in a single day, and you get a warranty on the work.
What causes under slab pipe leaks in Olathe homes?
The two biggest causes in Olathe are copper pipe pinholes from decades of contact with Johnson County's shifting clay soil, and abrasion where pipe rubs against concrete or gravel. Hot water lines fail first because heat speeds up corrosion. Homes built before 1990 with original copper are the most common calls we get.
How much does under slab pipe leak repair cost in Olathe?
Typical 2026 pricing in Olathe runs $600 to $2,500 for a single-spot repair, including detection, the concrete cut and patch, and pressure testing. Cost goes up with slab thickness, tile or hardwood flooring that must be removed and reset, and how deep the pipe sits. Rerouting a failing line instead of spot-repairing it usually runs $2,800 to $6,500.
Can you fix an under slab pipe leak without breaking the floor?
Sometimes, yes. If the leak is on a line that can be rerouted through the attic or walls, we can abandon the under-slab section and run new PEX pipe overhead, which means no concrete cutting at all. We check that option first and only cut the slab when rerouting is not practical or costs more than the repair.
