PlumbTex provides expert slab leak detection and repair services in Forney & Dallas, and Surrounding areas, helping homeowners identify and resolve water line failures beneath concrete foundations.

Whether it’s a small leak or a major breach in your plumbing lines, we offer fast, accurate, and minimally invasive solutions to restore integrity to your property.

Understanding Slab Leaks in Forney, Allen, & Dallas Homes

A slab leak occurs when a water line running beneath your home’s concrete foundation becomes cracked, corroded, or disconnected. These leaks can originate from hot or cold water lines, and they often remain hidden until signs of damage appear on the surface.


In Forney, slab leaks are more common in homes with aging copper or galvanized steel pipes, especially those built before the 2000s. Shifting soil, high water pressure, poor installation practices, and hard water corrosion all contribute to increased risk.

Common Signs of a Slab Leak

Slab leaks often present subtle warning signs before becoming visibly destructive. Forney homeowners should watch for the following indicators:

  • Unexplained Increase in Water Bills

    A consistent spike in your water bill with no change in usage can point to a hidden underground leak.

  • Warm or Damp Spots on Flooring

    If a specific area of your floor feels consistently warm, especially in tiled or concrete-finished spaces, it may be due to a hot water line leak beneath the slab.

  • Water Sounds When Pipes Are Off

    Hearing running water even when no taps or appliances are in use can suggest that water is escaping below the surface.

  • Cracks in Walls or Flooring

    As water erodes soil beneath the foundation, it may cause slight shifts that result in cracking tile, drywall, or even separation at baseboards.

  • Mold, Mildew, or Musty Odors

    Excess moisture from a slab leak can lead to mold growth under flooring and behind walls, triggering odors and potential health concerns.

Slab Leak Detection Services

Accurately locating a slab leak is the most critical step in the repair process. At PlumbTex, we use non-invasive detection methods designed to pinpoint the leak without unnecessary damage to your home’s foundation or interior surfaces.

Slab Leak Repair Options in Forney, Allen, & Dallas, TX

Once we’ve located the leak, our team determines the most effective and least invasive repair strategy. The method depends on the leak’s severity, location, and the type of piping used.

Direct Access Repair

This approach involves cutting a small section of the slab directly above the leak to access and replace the damaged portion of pipe. It’s ideal for isolated leaks with minimal disruption to living spaces.


We perform precise concrete cutting, localized repair or pipe replacement, and full restoration of the flooring afterward.

Pipe Rerouting

When pipes are heavily corroded or located under difficult-to-reach areas (such as kitchens or bathrooms), rerouting offers a long-term solution. We abandon the leaking section and reroute new piping through walls or ceilings.


This eliminates future slab intrusion and often improves system reliability. Rerouting is common in older Forney homes with multiple underground pipe failures.

Epoxy Pipe Coating

In select cases where accessing the pipe is not feasible and rerouting isn’t preferred, we offer in-place epoxy coating. This technique lines the interior of the pipe with a durable sealant, preventing further leaks without digging.


While not suitable for all types of leaks, this method offers minimal disruption and can extend the life of existing piping.

Preventing Future Slab Leaks

Proactive steps can help Forney homeowners reduce the likelihood of future slab leaks, especially in areas with expansive clay soils and variable water pressure.

  • Pressure Regulation

    Excessive water pressure accelerates pipe wear. We install and calibrate pressure-reducing valves (PRVs) to stabilize system pressure and prevent joint separation or pipe bursts.

  • Water Softening

    Forney’s hard water can cause mineral buildup and corrosion over time. Installing a water softener system helps protect internal plumbing from scale and reduces pipe degradation.

  • Annual Plumbing Inspections

    Our maintenance services include yearly inspections of exposed plumbing, leak detection tests, and early warning checks. This allows homeowners to spot small issues before they become structural problems.
