Water Leak Detection in Fresno, CA — Find It Fast, Fix It Right
Hidden water leaks silently damage your home and drive up your water bill. Stedman's licensed Fresno plumbers use advanced non-invasive technology to locate leaks fast — no guesswork, no unnecessary damage.
Water leaks don't always announce themselves. A pipe leaking inside a wall, beneath your slab, or deep in your crawlspace can go undetected for months — quietly driving up your water bill, feeding mold growth, and eroding structural elements of your home. By the time you see visible damage, the problem is often far more extensive than it first appears.
At Stedman's Plumbing, we use advanced non-invasive leak detection equipment to find exactly where a leak is before we ever open a wall or floor. We serve Fresno, Clovis, Madera, and the surrounding Central Valley with more than 30 years of combined plumbing experience. License #1110490.
Warning Signs of a Hidden Water Leak
Any of these signs warrants a call to a licensed plumber. Catching a leak early limits the damage significantly.
Quick Home Check: The Water Meter Test
Turn off all water inside and outside your home. Locate your water meter and note the reading. Wait 30 minutes without using any water. If the meter has moved, you likely have a leak somewhere in the system — call us for a professional inspection.
Our Leak Detection Technology
We don't guess — we use equipment. Our non-invasive approach means we pinpoint the leak location before any access work begins.
Acoustic Listening Equipment
Ground microphones and listening rods detect the sound of water escaping under pressure inside walls, beneath slabs, and underground. Even small leaks create a distinctive acoustic signature that our equipment picks up precisely.
Electronic Leak Detection
Electronic sensors read moisture levels and pressure variations in your plumbing system, helping us confirm a leak's presence and narrow down its location without destructive exploration.
Thermal Imaging & Moisture Detection
Thermal cameras detect temperature differentials caused by water behind walls and under floors. Moisture meters confirm wet areas with precision — together, they give us a clear picture before a single tile is lifted.
Types of Leaks We Find & Fix
Water leaks come from many sources — each requires a different diagnostic approach. Stedman's handles them all. Select a service below to learn more about each specific leak type.
Slab Leaks
Leaks in copper or PEX pipes running beneath your concrete slab foundation. High-urgency — can cause structural damage and significant water loss. Common in older Fresno homes.

Leaks at drain connections, P-traps, and drain pipe sections — from under the kitchen sink to deeper drain line failures. Often cause cabinet and subfloor damage.

Dripping kitchen, bathroom, and outdoor faucets caused by worn cartridges, O-rings, or valve seats. A faucet dripping once per second wastes over 3,000 gallons per year.

Gas leaks are a life-safety emergency. If you smell rotten egg odor, leave immediately and call 911. Stedman's handles gas line inspection, repair, and replacement for Fresno homes.

Running toilets, base leaks from a failed wax ring, tank-to-bowl leaks, and supply line failures. A running toilet can waste over 200 gallons per day undetected.

Corroded supply lines, cracked PVC drain pipes, and failed joints in the crawlspace beneath your home. Often discovered by inspectors or by musty odors rising through floors.

A hidden leak that goes unaddressed for weeks or months doesn't stay small. Here's what's at stake when a leak is left unrepaired:
Our Leak Detection Process
Every leak detection appointment follows a clear, transparent process — no hidden steps, no surprise work.
- Initial Consultation: We discuss your symptoms — water bill changes, odors, sounds, visible staining — to narrow the likely source and location before arriving on site.
- Water Meter Test: We verify whether an active leak is present using your water meter, confirming the scope before deploying equipment.
- Detection Equipment Deployed: Acoustic listening devices, electronic sensors, and thermal imaging tools are used systematically throughout the property to locate the leak.
- Locate the Leak: We identify the precise location of the leak — which pipe, which section, and the nearest access point needed for repair.
- Report Findings: We walk you through exactly what we found, show you the evidence, and explain the root cause in plain language.
- Repair Options Presented: We explain your repair options — targeted spot repair, rerouting, or full section replacement — and let you make an informed decision with no pressure.
Why Non-Invasive Detection Matters
We Find the Leak Before Opening Anything
Traditional "detect by destruction" approaches mean opening walls and floors on guesswork until the leak is found. The result is significant collateral damage to finishes, drywall, tile, and flooring that had nothing to do with the leak — all of which you have to repair afterward.
Our non-invasive approach is different. By deploying acoustic listening equipment, electronic sensors, and thermal imaging first, we know exactly where the leak is before a single tile is lifted or a single wall is opened. This means:
- Surgical access — only what's necessary, nothing more
- Less disruption to your home's finishes and structure
- Faster detection, faster repair
- Confident repair — we know exactly what we're dealing with before we begin
- Lower total repair effort compared to blind exploratory access
For Fresno homeowners with tiled floors, finished walls, or hardwood over a slab, this distinction matters enormously.
Frequently Asked Questions
Licensed plumbers use acoustic listening devices to hear water escaping under pressure inside walls and floors, electronic leak detection equipment that picks up moisture signatures, and thermal imaging cameras that reveal temperature differences caused by hidden water. These non-invasive methods let us pinpoint the leak location before any wall or floor is opened.
Common signs include an unexplained spike in your water bill, your water meter moving when all fixtures are off, damp or discolored patches on walls or ceilings, a musty or mold odor, low water pressure, and warm spots on the floor. You can confirm with a simple water meter test: turn off all water, read the meter, wait 30 minutes without using any water, and check again. If the meter has moved, call a plumber.
No — that's exactly what our non-invasive approach avoids. We use acoustic equipment, electronic sensors, and thermal imaging to pinpoint the leak precisely. Only after we know the exact location do we discuss any access needed for repair. This saves significant disruption and expense compared to exploratory opening.
Most residential leak detection appointments take between one and three hours, depending on the size of the property and the complexity of the situation. We complete a thorough inspection rather than a quick pass, so you get an accurate result on the first visit.
We walk you through exactly what we found and where, explain the repair options available, and let you decide how to proceed. In many cases we can begin repairs the same day. We don't perform unnecessary work — our goal is a targeted, durable fix that resolves the issue completely.
