Advanced Leak Detection & Repair Services | North Georgia & Metro Atlanta

Main Water Line & Yard Line Services

We specialize in detecting and repairing leaks in your mainline water service. Whether you have a leak in your yard or need a full yard line replacement, our trenchless technology ensures a quick fix with minimal landscape damage.

From the annoyance of an unexplained spike in your water bill to the worry of a mysterious wet patch on your drywall or a water meter that never stops spinning, Greenlee Plumbing is here to help. We combine cutting-edge technology with real-world experience to find hidden leaks quickly and accurately. Our advanced leak detection toolkit includes tracer gas injection, high-sensitivity gas sniffers, thermal imaging cameras, and acoustic listening equipment—allowing us to serve homeowners throughout North Georgia and Metro Atlanta without unnecessary damage to your property.

We start every job by prioritizing your home’s structure. Our team uses a safe, non-toxic blend of hydrogen and nitrogen gas (tracer gas) that is introduced directly into your plumbing system. This gas is designed to seep out from even the tiniest cracks, pinhole leaks, or failed joints—whether in a concrete slab, behind a wall, or underground. Our precision gas detectors then hone in on the exact escape point, eliminating the need for exploratory digging, tearing out tile, or breaking up concrete. This approach is especially effective for slab leaks, buried pipe failures, and hidden issues in single-family or multi-unit residences, saving you money on repairs while preventing major water damage.

To leave nothing to chance, we don’t rely on a single method. Our technicians also deploy infrared leak detection cameras that reveal cool spots from evaporating moisture behind surfaces, alongside acoustic listening devices that amplify the faint sound of water escaping under pressure. This layered strategy lets us accurately locate leaks in supply lines, drain systems, or inside wall cavities—stopping mold growth, structural rot, and exorbitant water bills before they get worse. Unlike old-school techniques that require destructive guesswork, our process is minimally invasive and ideal for plumbing systems in historic homes, new builds, and everything in between.

Our Simple 4-Step Leak Detection Process:

2. Thorough System Scan – Our techs arrive fully equipped with tracer gas injectors, sensitive gas detectors, thermal imaging cameras, and acoustic listening tools. We’ll examine your entire plumbing setup to find where water is escaping—be it under a concrete slab, inside a wall, or along a buried main line.
3. Pinpoint Diagnosis & Clear Options – Once the leak is found, we explain exactly what we discovered, where it is, and what repair methods make the most sense. No surprises, just honest communication at every step.
4. Efficient Repair & Long-Term Solutions – After locating the problem, we get to work fixing it with minimal disruption to your daily life. If we uncover widespread corrosion or repeated failures, we’ll also discuss whole-home repiping options (available in Gainesville, GA) to give you peace of mind for years to come.
