Slab leaks are among the most serious plumbing problems a homeowner can face. Left undetected, they can lead to structural damage, foundation instability, mold growth, and skyrocketing water bills. At JMS Plumbing & Heating, we offer expert slab leak detection and repair in Cortland, NY, using advanced camera inspection and leak location technology to find and fix leaks beneath concrete floors without unnecessary destruction.
Whether you're dealing with warm spots on your floor, the sound of running water with no fixtures on, or mysterious increases in water usage, JMS is your go-to team for fast, accurate slab leak solutions. We proudly serve Cortland, Homer, McGraw, Dryden, Groton, and Freeville with professional service backed by more than 25 years of experience.
A slab leak is a water leak that occurs in a pipe running beneath the concrete foundation (or "slab") of your home. These pipes, often made of copper, PEX, or galvanized steel, carry pressurized water or drain wastewater to and from your plumbing fixtures.
When one of these pipes corrodes, cracks, or becomes damaged, water can begin leaking under the slab — often undetected for weeks or even months — until visible symptoms begin to surface.
Regardless of the cause, JMS has the tools and experience to locate and resolve slab leaks with minimal damage and maximum accuracy.
Since the leak occurs beneath your flooring, it often goes unnoticed until damage is done. Early detection is key — and our camera and acoustic detection tools can pinpoint the source even when symptoms are subtle.
If you notice one or more of these issues, call JMS right away. A slab leak won't fix itself — and the longer it continues, the more costly it becomes.
JMS uses non-invasive slab leak detection tools to accurately locate the source of the problem without tearing up flooring or guessing. Our goal is to pinpoint the leak's location and offer the best repair method with minimal impact to your home.
Initial evaluation
We review your symptoms, plumbing system layout, and history.
Pressure testing
We isolate parts of your plumbing system and check for pressure loss.
Camera inspection
Using our in-line plumbing camera, we inspect drain lines and water lines under the slab.
Acoustic leak detection
We use sensitive microphones to listen for the sound of water escaping pressurized pipes.
Infrared scanning
We use thermal imaging to locate hot spots caused by leaks in heated water lines.
Precise location marking
Once the leak is found, we mark it for targeted repair.
This high-tech approach ensures accuracy, saving time, money, and your flooring.
Once the leak is located, JMS will recommend the most efficient, least invasive repair strategy. Every home and leak is different, so we tailor the approach to your needs and layout.
JMS always explains your options clearly, including costs, timelines, and pros/cons of each method.
Our slab leak detection includes video camera pipe inspection, which allows us to see inside your drain and sometimes water lines. We identify breaks, separations, root intrusion, and other defects without removing flooring or walls.
We provide footage upon request so you can see exactly what we see — transparency is a core part of our process.

A slab leak is a water leak under the concrete foundation (or slab) of your home. It usually affects water supply lines or drain pipes that run beneath your floors.
Slab leaks are typically caused by pipe corrosion, ground movement, high water pressure, poor installation, or abrasion from pipes rubbing against concrete.
Signs include increased water bills, warm floor spots, low water pressure, damp flooring, mold smells, or the sound of running water when no fixtures are on.
We use a combination of camera inspection, acoustic listening equipment, infrared heat detection, and pressure testing to accurately locate the leak beneath your slab.
Not always. JMS offers multiple repair options, including rerouting or trenchless repairs, which can often avoid cutting into floors altogether.

Usually not. Most slab leak repairs are localized and can be completed while you remain in the home, especially if rerouting or trenchless methods are used.
