Water Bills That Climb Without Explanation

Leak Detection & Repair in Bossier City for slab leaks, hidden pipe leaks, and unexplained water loss

Slab foundations are common across Bossier City, and hidden slab leaks represent a slow-discovery, high-cost problem that neighborhoods near Barksdale and Cross Lake deal with regularly. Water leaking beneath a concrete slab often goes unnoticed until flooring warps, water bills spike, or foundation settling becomes visible. Hennigan Plumbing locates and repairs hidden leaks in residential and commercial properties across the Ark-La-Tex using camera and detection tools that pinpoint the problem before any cutting or digging begins. This approach minimizes unnecessary demolition, reduces yard disruption, and prevents the find-it-by-trial-and-error approach that leaves properties torn apart during the search.


Non-invasive diagnostic methods assess pressure loss, isolate sections of pipe, and use electronic leak detection to locate the failure point precisely. Slab leaks are identified through thermal imaging, acoustic listening, or pressure testing that narrows the search area to a few square feet rather than guessing across an entire foundation footprint.


Schedule a leak detection assessment when water bills increase without usage changes, when you hear running water with all fixtures off, or when flooring shows unexplained moisture.

Why Leak Location Comes Before Demolition

Leak detection identifies the failure point before breaking through concrete, drywall, or landscaping, a process that saves both time and repair costs. Camera inspection and electronic listening devices locate leaks in supply lines, drain lines, and irrigation systems without exploratory demolition. Once the leak is pinpointed, repair involves accessing only the damaged section rather than exposing long runs of pipe to find the problem.


After repair, you notice water bills return to normal levels, the sound of running water stops, and moisture damage no longer spreads across floors or walls. Slab leak repairs typically involve cutting a small access opening in the concrete, replacing the damaged pipe section, pressure-testing the repair, and patching the slab—foundation integrity is maintained throughout the process.


Detection tools include pressure gauges, thermal cameras, acoustic sensors, and video inspection equipment, all used to isolate leaks without guesswork. Some leaks occur in accessible locations like crawl spaces or attics, while others hide beneath slabs, inside walls, or underground—detection methods adjust based on pipe location and symptoms.

Common Questions About This Service

Property owners dealing with hidden leaks or unexplained water loss across Shreveport and Bossier City often ask similar questions before scheduling detection service.

  • How do you locate a slab leak without tearing up the entire floor?

    Electronic leak detection and thermal imaging isolate the failure point to a small area, allowing targeted access through the slab rather than exploratory demolition across the foundation—detection narrows the search to a few square feet.

  • What causes slab leaks in Bossier City homes?

    Shifting soil, foundation settling, corrosion of copper supply lines, and pressure stress at pipe bends or joints all contribute to slab leaks—homes built on expansive clay soils near Cross Lake see this more frequently due to seasonal ground movement.

  • Can you detect leaks in irrigation lines and outdoor plumbing?

    Yes—detection tools locate leaks in underground irrigation systems, exterior hose bibs, and buried supply lines using pressure testing and acoustic methods similar to those used for interior plumbing.

  • What happens if the leak is inside a wall instead of under the slab?

    Wall leaks are located using moisture meters, thermal imaging, and pressure isolation, then accessed through the smallest opening necessary to reach the damaged pipe—drywall is patched after repair is complete.

  • How long does leak detection take?

    Detection time depends on leak location and building layout, but most residential leaks are pinpointed within a few hours using systematic pressure testing and electronic listening—repair timing varies based on access difficulty and pipe material.

Hennigan Plumbing operates with the same assess-before-acting approach on every leak detection call, finding the problem first and fixing it right without unnecessary property damage. Request leak detection service when water loss or moisture appears without an obvious source.
