Water Leak Detection in Shreveport, LA

Non-Invasive Leak Detection Using Advanced Electronic and Thermal Imaging Technology

Hidden water leaks waste thousands of gallons, inflate utility bills, and cause structural damage long before they become visible. Mark Johnson & Sons Plumbing provides professional water leak detection services across Shreveport using electronic acoustic sensors, thermal imaging cameras, and pressure testing equipment — locating leaks behind walls, under slabs, and underground without unnecessary demolition. As part of our comprehensive plumbing services in Shreveport, we deliver professional results backed by decades of experience.

Why Leak Detection Matters

The average hidden leak wastes over 10,000 gallons of water per year, and many Shreveport homes have multiple undetected leaks running simultaneously. A dripping supply line behind drywall may seem insignificant, but over months it saturates insulation, weakens framing, and creates conditions for mold colonies that thrive in Northern Louisiana’s warm, humid environment.

Underground leaks between the water meter and the house present a different challenge. The clay soil common throughout Caddo Parish can absorb and conceal leaking water for extended periods, masking the problem until the yard becomes soft, the foundation shifts, or the water bill arrives with an alarming total. By that point, hundreds or even thousands of dollars in water charges have already accumulated.

Professional leak detection eliminates guesswork. Instead of cutting into walls or digging up the yard hoping to find the source, advanced equipment isolates the leak’s exact location so repairs can be targeted, efficient, and minimally disruptive.

Our Leak Detection Services

Electronic Acoustic Detection

We use ground microphones and acoustic amplifiers to listen for the distinct sound of pressurized water escaping through a pipe wall. This method is highly effective for locating leaks in supply lines under concrete slabs, behind walls, and in underground service lines.

Thermal Imaging

Infrared cameras detect temperature differences caused by moisture accumulation behind walls, under floors, and in ceilings. Hot water leaks produce clear thermal signatures, and even cold water leaks alter surface temperatures enough to appear on imaging scans.

Pressure Testing & Isolation

We systematically isolate sections of your plumbing system and monitor pressure gauges to determine which branch contains the leak. This method narrows the search area before deploying acoustic or thermal tools, reducing detection time and cost.

Tracer Gas Detection

For leaks that are difficult to locate with acoustic or thermal methods — particularly in complex commercial piping layouts — we introduce a safe, inert tracer gas into the line and use sensitive detectors at the surface to identify the exact escape point.

Meter Analysis

A simple but effective first step: with all fixtures off, we monitor your water meter for movement. A spinning dial or advancing digital readout confirms an active leak somewhere in the system and justifies further investigation.

Frequently Asked Questions

How accurate is electronic leak detection?

Modern acoustic and thermal detection equipment can locate leaks to within inches in most residential settings. Combined with pressure isolation testing, we achieve a high degree of precision that minimizes the area needing to be opened for repair.

Do you repair the leak after you find it, or just locate it?

We handle both. Our technicians are licensed journeyman plumbers, so once the leak is located, we can proceed directly to repair — often completing detection and repair in a single visit.

How much water can a hidden leak waste?

Even a slow, steady drip can waste over 10,000 gallons per year. A pinhole leak in a pressurized supply line wastes considerably more and can cause thousands of dollars in water damage to your home’s structure and finishes.

Will the City of Shreveport adjust my water bill for a detected leak?

Shreveport Water and Sewerage may offer a billing adjustment for documented leaks on your side of the meter. We provide the repair documentation needed to support an adjustment request.

Can thermal imaging detect leaks through concrete?

Thermal imaging is most effective on walls, ceilings, and above-grade floors. For slab leaks, acoustic detection is typically more reliable because concrete insulates temperature differences. We use the right tool for each situation.

How do I know if the leak is on my side of the meter or the city’s?

We can determine this with a simple shutoff test. If your main shutoff valve is closed and the meter stops moving, the leak is on your property’s side. If the meter continues to advance, the issue is between the meter and the main — which is typically the utility’s responsibility.

Can you detect leaks in swimming pool plumbing?

Yes. We use pressure testing and acoustic methods to locate leaks in pool supply and return lines, skimmer connections, and main drain piping. Pool leak detection is a separate evaluation from household plumbing.

Is leak detection covered by homeowner’s insurance?

Detection costs are sometimes covered when the investigation leads to a covered claim, such as sudden water damage. Coverage varies by policy and carrier. We recommend checking with your insurer before scheduling and can provide documentation either way.

How often should I have my plumbing checked for leaks?

An annual plumbing inspection is a sound preventive measure, especially for homes more than 20 years old. Between inspections, monitor your water bill for unexplained increases — that is often the first sign of a developing leak.

Do you detect gas leaks as well?

Yes. We offer gas leak detection as a separate service using combustible-gas analyzers and pressure-drop testing. If you smell gas, leave your home immediately and call us after contacting 911.
