Leak Detection & Repair in Forney & Dallas

PlumbTex offers professional leak detection and repair services in Forney & Dallas and surrounding areas using advanced technology and minimally invasive methods to locate and resolve water leaks in residential plumbing systems. Whether you're dealing with hidden pipe leaks behind walls, ceiling drips, or rising water bills without explanation, our team delivers precise diagnostics and lasting repairs.


Leaks can originate from multiple areas of the home—under floors, inside walls, beneath slabs, or in outdoor piping—and even minor leaks can lead to significant damage over time. Our local knowledge, combined with advanced equipment, allows us to quickly identify leaks and restore your plumbing system’s integrity.

Detecting Water Leaks in Your Forney, Allen, & Dallas Home

Unaddressed leaks can cause long-term structural damage, mold growth, and increased utility costs. Detecting them early reduces the risk of costly repairs and health hazards associated with moisture buildup.

Common Signs of a Plumbing Leak

Leaks aren’t always obvious, but there are several warning signs that indicate water is escaping somewhere in your system:

  • Sudden Increase in Water Bills

    One of the earliest signs of a leak is an unexplained spike in your monthly water bill. Even small, constant drips from a hidden pipe can waste hundreds of gallons per month.

  • Wet or Discolored Walls and Ceilings

    Water stains, warping, or bubbling paint on interior surfaces often indicate a leak behind walls or above ceilings, especially if located near bathrooms, laundry rooms, or kitchens.

  • Musty Odors or Mold Growth

    Persistent moisture from leaks encourages the growth of mold and mildew, which thrive in dark, hidden areas. Musty smells or visible patches on walls are signs that water may be collecting nearby.

  • Unusual Sounds in the Plumbing

    If you hear dripping, hissing, or running water even when taps are off, there may be a hidden leak behind walls or beneath floors.

  • Low Water Pressure or Inconsistent Flow

    Leaks in supply lines can reduce pressure at fixtures throughout the home, particularly in showers or multi-outlet systems.

Advanced Leak Detection Technology

PlumbTex uses modern tools and non-invasive techniques to locate leaks with precision, minimizing the need for cutting into walls or tearing up flooring unnecessarily.

Acoustic Listening Devices

These instruments detect the sound frequency of escaping water, helping us identify leaks beneath concrete slabs, behind walls, or within crawl spaces.

Infrared Thermal Imaging

Thermal cameras pick up temperature anomalies caused by leaking hot or cold water pipes. This is especially useful for concealed leaks in walls or ceilings.

Pressure Testing

We isolate different plumbing zones within your home and perform static pressure tests to identify drops in pressure that suggest leaks.

Moisture Sensors

In high-risk areas like laundry rooms and bathrooms, we use moisture readers to identify dampness behind surfaces and track leak progression.

Targeted Leak Repair Services

Once the source of the leak is confirmed, our licensed plumbers perform the appropriate repair using durable, code-compliant materials. The type of repair depends on the leak’s location, severity, and surrounding construction.

  • Behind-Wall Pipe Repairs

    We cut and access the affected area with precision, repair or replace the leaking section of pipe, and seal the wall with moisture-resistant materials. We take care to minimize disruption and complete most wall leak repairs in a single visit.

  • Under-Slab Leak Repairs

    Leaks beneath concrete slabs may require direct access through the foundation or pipe rerouting to avoid future slab intrusion. PlumbTex offers both repair methods depending on the scope of the problem, and we advise on the least invasive and most cost-effective option.

  • Fixture Leak Repairs

    Leaking faucets, toilets, and showers are often caused by worn gaskets, seals, or internal valves. We service all major brands and replace defective components to eliminate drips and improve fixture performance.

  • Outdoor and Irrigation Leak Repairs

    Leaks in outdoor hose bibs, irrigation lines, or underground yard pipes waste significant water and may go undetected for weeks. We locate these issues using ground listening tools and perform trenchless or minimally invasive line repairs when possible.

Water Damage Prevention and Long-Term Solutions

In addition to repairs, we offer preventative upgrades to reduce the risk of future leaks in your plumbing system.
