Service overview

Water Leak Detection Under Concrete Olathe KS

Water Leak Detection Under Concrete Olathe KS is a non-invasive diagnostic service that pinpoints leaks in the copper or PEX pipe running beneath your slab foundation. We pressurize the line with a gauge, then listen through the concrete with acoustic equipment and scan for temperature changes with a FLIR thermal imaging camera. A moisture meter confirms the reading. You get an exact location marked on the floor, not a guess about which room to jackhammer first. Most Olathe homes built before 1995 still have copper supply lines under the slab, and Johnson County's clay soil shifts enough to stress those joints over time. A cold water line slab leak shows up as water pooling around the foundation. A hot water line slab leak leaves warm spots on the floor. If you search for water leak detection under concrete near me Olathe KS, we can usually get a technician out the same day to confirm what is happening.

! Common warning signs

Water bill doubled with no change in usage

A hidden slab leak can waste thousands of gallons a month and cost you hundreds of dollars. It also softens soil under the foundation, which leads to cracks and settling.

Warm spot on the floor that will not cool down

A warm spot means a hot water line is leaking under the slab. It wastes energy, raises your gas or electric bill, and gets worse over time as the leak erodes more soil.

Water pooling around the foundation after dry weather

Water pooling outside the foundation usually traces to a cold water slab leak. It can undermine the footing, cause cracks in walls, and create a permanent wet spot in the yard.

Scope of work

What our under-concrete leak detection includes

Every detection visit covers the full diagnostic process from pressure test to written report. We do not cut concrete during detection. Repair work is quoted separately after you see the evidence.

  • 01

    Hot and cold line pressure testing

    We isolate both lines and attach a pressure testing gauge. A dropping needle confirms which line is leaking. This takes about 20 minutes and tells us where to focus the acoustic scan.

  • 02

    Acoustic and thermal scanning

    A technician walks the floor with a listening disc and acoustic leak detection equipment, then sweeps the same area with a FLIR thermal imaging camera. We compare sound and temperature data to narrow the leak to a small zone.

  • 03

    Moisture verification

    We confirm the scan with a Fluke moisture meter and, when accessible, a video pipe inspection camera. You see the readings on screen. If we cannot confirm the leak, we tell you and you do not pay for a guess.

  • 04

    Written location report

    You get a printed report with the marked leak location, photos, and pressure test results. This document supports insurance claims and gives any repair contractor a precise starting point. Most reports are ready before we leave.

Why pinpoint detection saves you money

Breaking concrete to hunt for a leak costs thousands. Finding it first costs a fraction of that. Here is what accurate detection gets you.

Schedule detection

Equipment we use to find slab leaks

FLIR thermal imaging camera

Maps temperature differences on the floor to reveal hot water leaks as warm spots and cold water leaks as cool zones. We combine this with acoustic data for a confident location.

Sewerin acoustic listening disc

Picks up the sound of pressurized water escaping a pipe under concrete. We walk the floor and compare readings to narrow the leak to a small target zone.

RIDGID pressure testing gauge

Isolates and pressurizes the hot and cold lines. A dropping needle confirms a slab leak before we bring in the scanning equipment.

General Pipe Cleaners video inspection camera

We push this camera through accessible drain lines to check for sewer pipe leaks under the slab. It also helps verify repair quality after work is done.

Local execution

Olathe sits on Johnson County clay that expands when wet and shrinks when dry. That movement stresses under-slab copper and PEX lines year after year. Homes built before 1995 usually have copper pipe, which develops pinhole leaks at joints. Newer builds use PEX, which can fail at crimp fittings. Our detection approach accounts for both. We also know that Olathe's freeze-thaw cycles in winter and dry summers in July and August are when most slab leaks surface. If you need water leak detection under concrete in Olathe Kansas, we bring the right gear for your home's age and pipe material. We pull a Johnson County Plumbing Permit when repair is required and follow the IAPMO Uniform Plumbing Code on every pressure test. Whether you are in a 1960s ranch near Downtown or a new build in Stonebridge, we can find the leak without tearing up your floor.

Recent work

Hot water leak in a 1970s ranch [ A homeowner in Havencroft noticed a warm spot in the hallway and a water bill that jumped from $75 to $290. Two other plumbers had guessed at the location and wanted to jackhammer the bathroom floor. Nothing was confirmed. ]
Cold water leak near the foundation [ We used electronic leak detection and a pipe locator to trace the cold water line. The leak was 18 inches from the foundation wall. We repaired the line and backfilled with self-leveling compound. The pooling stopped immediately. ]

How our detection process works

1

Phone triage

You call (913) 358-1454 and describe the symptoms: high water bill, warm floor spot, water pooling around the foundation. We ask a few questions to rule out a running toilet or irrigation leak. If it sounds like a slab leak, we book a two-hour detection window.

2

Pressure test

We isolate the hot and cold lines and attach a pressure testing gauge. If the needle drops, you have a confirmed under slab pipe leak. This takes about 20 minutes and tells us which line is failing before we bring in the listening equipment.

3

Acoustic and thermal scan

A technician walks the floor with a listening disc and acoustic leak detection equipment, then sweeps the same area with a FLIR thermal imaging camera. We compare the sound signature and temperature map to narrow the leak to a small zone. This is the step that saves your floor.

What slab leak detection costs in Olathe

Detection pricing in Olathe for 2026 runs $250 to $550 for a standard residential job. That covers pressure testing, acoustic scanning, thermal imaging, and a written location report. The exact price depends on how many lines we test and how large the slab is. We give you a flat fee before we start. If you need under concrete leak detection Olathe KS, call us and we will quote your specific address.

01

Number of lines tested

Most homes have one hot and one cold supply line under the slab. If you have a recirculating hot water system or multiple zones, we test each one. Each additional line adds time and cost.

02

Slab size and flooring

A larger slab takes longer to scan. Thick tile or hardwood can dampen acoustic signals, so we may need extra time with thermal imaging. We account for this in the flat fee.

03

Access and obstructions

Furniture, rugs, and built-in cabinets slow the scan. If we have to move heavy items or work around a finished basement, the job takes longer. We ask about this when you book.

Frequently asked questions

How do you detect a water leak under concrete in Olathe KS?

We pressure-test the line first, then use acoustic listening discs and a thermal imaging camera to hear and see the leak through the slab. A moisture meter confirms the spot. Most detections take 90 minutes to two hours. You get a marked location on the floor and a written report the same day.

What causes water leaks under concrete slabs in Olathe?

The two main causes in Olathe are copper pipe corrosion and soil movement. Johnson County clay expands and contracts with wet and dry cycles, which stresses pipe fittings under the slab. Older copper lines also develop pinhole leaks. PEX pipe can fail at crimp fittings. Most leaks we find are at joints, not mid-pipe.

How much does water leak detection under concrete cost in Olathe?

Typical 2026 detection pricing in Olathe runs $250 to $550 depending on how many lines we test and how difficult the slab is to scan. That fee covers pressure testing, acoustic scanning, thermal imaging, and the written location report. Repair costs are separate and quoted after we know the scope.

Can you find a water leak under concrete without breaking it in Olathe?

Yes. Acoustic and thermal detection are non-invasive. We do not cut or break concrete during detection. We mark the leak location on the surface so your repair contractor makes one targeted cut instead of exploratory demolition. That saves you hundreds in concrete patch and labor costs.
