Find Hidden Leaks Before Damage Spreads

Leak detection services in East Texas locate water loss in walls, slabs, and underground lines using professional tools and methods.

Hidden leaks in your Longview and surrouding areas homes waste water, drive up your utility bill, and damage framing, drywall, and flooring before you realize there is a problem. Water running inside a wall or under a slab does not announce itself with puddles or dripping sounds, but it does leave clues such as warm spots on your floor, peeling paint, mold growth in unexpected places, or a water meter that spins when no fixtures are in use. By the time these signs become obvious, the leak may have been active for weeks or months.


Thomas and Young Plumbing Services, LLC uses listening devices, thermal imaging, and pressure testing to locate leaks without tearing through large sections of your home or yard. The service pinpoints the leak so repairs can be targeted and efficient, reducing the cost and disruption that come with exploratory demolition in Longview and surrounding areas. Once the leak is found and fixed, water stops flowing into areas where it does not belong, your bill returns to normal, and the risk of mold and structural damage drops immediately.


If your water bill has climbed without explanation, or if you notice damp spots, musty odors, or unexplained warm areas on your floor, contact us to schedule a leak detection service before the damage expands.

How Professional Leak Detection Works

Detection begins by isolating sections of your plumbing system and monitoring for pressure loss that indicates a leak in Longview and surrounding areas. Thomas and Young Plumbing Services, LLC uses acoustic listening tools to detect the sound of water escaping from pipes inside walls or under slabs, and thermal imaging cameras reveal temperature differences caused by water movement. These methods locate leaks without cutting into drywall or breaking concrete until the exact spot is confirmed.


After the leak is located and repaired, water stops seeping into insulation, subflooring, and wall cavities, and the conditions that promote mold growth are eliminated. Your water meter stops running when all fixtures are off, and monthly usage returns to expected levels.


This service is suitable for residential and commercial properties and works on supply lines, slab leaks, and underground piping. Leak detection does not include the repair itself, but knowing the location allows your plumber to access the damaged pipe with minimal disruption. Early detection reduces repair costs by preventing secondary damage to flooring, cabinetry, and structural elements that would otherwise require replacement after prolonged exposure to moisture.

Answers to Help You Decide

Homeowners in Longview and surrouding areas often have questions about leak detection when they suspect a problem but cannot see the source or when their water bill suggests waste they cannot explain.

What are the signs of a hidden leak?
You may notice a higher water bill, hear running water when all fixtures are off, see wet spots or discoloration on walls and ceilings, or feel warm areas on your floor above a slab leak. Mold growth in unusual places also suggests hidden moisture.
How accurate is leak detection?
Professional tools used by Thomas and Young Plumbing Services, LLC locate leaks within a few feet or closer, allowing targeted access without large-scale demolition. Accuracy depends on pipe material, depth, and accessibility, but results are far more precise than guessing.
Will you have to tear up my floors or walls?
Detection tools locate the leak before any cutting or digging begins, so disruption is limited to the immediate area where the pipe needs repair. You avoid the cost and mess of exploratory work that may miss the leak entirely.
How long does leak detection take?

Most residential leak detection services in Longview and surrounding areas take one to two hours depending on the size of your home and the complexity of your plumbing layout. You receive a clear location and recommended next steps before the technician leaves.

What happens if I ignore a hidden leak?
Ongoing leaks rot wood framing, damage drywall and insulation, and create the damp conditions where mold thrives. Repair costs increase as structural elements deteriorate, and your water bill continues to climb until the leak is stopped.
