Slab Leak Repair in DFW, TX

Hidden pipes, real consequences

A slab leak is a break or pinhole in a water or sewer line buried beneath your home’s concrete foundation. Most homes across North Texas, including Nevada, sit on concrete slab foundations. That means the pipes carrying water in and waste out run right under that concrete.

When one of those pipes fails, water escapes into the ground below your home. You may not notice it happening, but it doesn’t stop on its own. Over time, that moisture erodes the soil, shifts the slab, and turns a plumbing problem into a structural one. The earlier you catch a slab leak, the less it costs to fix.

Six signs you may have a slab leak

Slab leaks are easy to miss early on because the pipe is completely hidden. Instead of a visible drip, you get secondary signals that most homeowners chalk up to something else. Here’s what to watch for:

• Unexplained water bill increase: If your usage hasn’t changed but your bill jumped, water is escaping somewhere it shouldn’t be.
• Warm or wet spots on your floor: A hot water line leak creates warm patches on hard flooring. Cold water line leaks show up as damp or soft areas, especially on hardwood or laminate.
• Sound of running water with no fixtures on: Hearing water move through your home when everything is shut off is a real red flag.
• Persistent low water pressure: A break in the line bleeds off pressure throughout the house, even when you can’t see or hear the leak itself.
• New cracks in walls or flooring: Prolonged moisture beneath the slab causes soil movement, which shifts your foundation and cracks drywall, tile grout, and masonry.
• Musty or mildew smell: Moisture trapped under a concrete slab is a good environment for mold. You’ll usually smell it long before you see it.

If one or more of these are showing up at once, calling now is the right move — not after the next water bill arrives.

How we find the leak before we touch the floor

Cutting into a concrete slab in the wrong spot is an expensive mistake. Getting the detection right is what separates a one-cut job from a three-cut job. We locate the leak accurately before any demolition begins.

The flat fee for sending a plumber to you within normal hours (7am-5pm) is $49. Outside of normal hours, the fee increases to $200. Additional cost depends on the method deemed necessary to fix the issue.

Electronic listening equipment

We use acoustic listening devices to trace the sound of escaping water through the slab. This equipment can pinpoint a leak within inches, which cuts out the guesswork that leads to unnecessary concrete removal.

Pressure testing

We isolate individual lines and run pressure tests to confirm where the failure is and how severe it is. This also tells us whether the problem is isolated to one pipe or affecting more of the system.

Thermal imaging (when applicable)

For hot water line leaks, thermal imaging gives us a picture of temperature variation across your floor. A leaking hot water line shows up as a heat signature, even through tile or hardwood.

We’ll walk you through what we found before any work begins. You’ll know what’s leaking, where it is, and what it’ll take to fix it.

Slab leak repair methods we use

The right fix depends on where the leak is, what shape the surrounding plumbing is in, and how much floor disruption makes sense. We explain the options for every job. You decide what fits.

Spot repair

When the leak is in an accessible area and the surrounding pipe is in solid shape, we open a targeted section of concrete, repair or replace the damaged section, repour the concrete, and restore the surface. It’s the most direct fix when conditions support it.

Pipe rerouting

When the damaged pipe runs beneath heavy tile work or a structural section of the slab, rerouting is often the smarter long-term call. We redirect the supply line through the walls or attic, bypassing the old underground pipe entirely. The slab stays intact.

Epoxy pipe lining

For certain pipe sizes and layouts, we can seal the leak from the inside with an epoxy liner, no concrete removal required. It works best when the pipe’s overall structure is still sound outside the leak point.

We’ll give you a straight read on which option fits your situation, and why. If a less invasive approach will hold up just as well, that’s the one we’ll call.
