Emergency Slab Leak Detection & Repair in Carrollton, TX
A warm spot on the floor, a water bill that suddenly doubles, or a water heater that won't stop cycling can all point to a leak under your slab. We pinpoint it before anything gets torn out.
Call (469) 856-7724Most homes in Carrollton, like most homes across North Texas, sit on a concrete slab foundation, which means the main water supply lines often run underneath or through that slab. When one of those lines develops a leak, there's no puddle to point to, and the signs that do show up are easy to miss until the damage has already spread.
Carrollton's hard water adds another factor. Mineral buildup inside older galvanized lines can corrode through the pipe wall from the inside out, which makes a slab leak more likely in homes still running original supply lines from the postwar growth years.
Why Is My Water Bill Suddenly So High With No Visible Leak?
A slab leak rarely announces itself directly. Instead, it tends to show up as one or more of a handful of secondary symptoms, and the earliest of them often isn't the one people expect.
Signs of a leak under the slab
- ✓A water heater cycling or running more than it used to, often the earliest sign, before anything else is noticeable
- ✓A warm or hot spot on the floor, a sign specific to a leaking hot-water line
- ✓A water bill that jumps sharply with no change in household usage
- ✓The water meter still spinning when every tap and appliance in the house is off
- ✓Damp, discolored, or warped flooring, more typical of a cold-water line leak
- ✓Cracks in flooring or nearby walls after a leak has gone unnoticed for a while
Confirming It: The Meter Test
Before any repair conversation, we confirm the leak is real and get a sense of its severity. The simplest homeowner-side check is to shut off every fixture and appliance that uses water, then watch the water meter. If it keeps moving with everything off, water is escaping somewhere in the system. Research on residential leak signatures has found that the volume of water lost on a given day follows a fairly consistent pattern once a leak starts, which is part of why a sudden, sustained bill increase is such a reliable indicator rather than a coincidence.
The EPA estimates that undetected household leaks waste an average of roughly 10,000 gallons of water per year nationally, and a slab leak running for months before detection can push well past that single-family average.
How We Pinpoint a Slab Leak Without Guessing
Electronic leak detection equipment listens for the specific acoustic signature of water escaping a pressurized line under concrete, which narrows the leak's location down to a small area before any concrete gets opened. That precision is what separates a targeted slab leak repair from tearing out flooring on a hunch.
Once the leak is located, the repair path depends on where it sits and how accessible that section of line is.
| Situation | Typical Repair Approach |
|---|---|
| Leak in an accessible section of slab | Direct spot repair through the slab |
| Leak in a hard-to-access section, or near a footing | Reroute the line above the slab instead |
| Multiple leaks or widespread galvanized corrosion | Full repipe is often more practical than repeated spot repairs |
What to Do Before We Arrive
A few steps while you wait help limit damage and give us useful information once we start the acoustic leak detection.
Before we get there
- ✓Shut off the main water supply if the leak seems significant or is causing visible flooring damage
- ✓Note the water meter reading with everything off, and check it again after an hour to confirm movement
- ✓Keep foot traffic away from any warm or damp spot on the floor
- ✓Have recent water bills on hand if you have them, since a sudden jump helps confirm the timeline
Do You Repair It Too, or Only Find It?
We handle both the detection and the repair, so there's no separate call needed once the leak is pinpointed. If a previous plumber or leak detection company already located a leak but couldn't resolve it, or if you're unsure the original diagnosis was right, we can re-verify the location before starting repair work rather than assuming the earlier report was correct.
Slab Leaks and Homeowners Insurance
Many homeowners insurance policies cover sudden, accidental water damage but exclude damage caused by a leak that developed gradually over time, so how a claim gets classified matters. Insurers generally want to see the date the leak was discovered along with a plumber's leak-detection report documenting the location and cause. We provide that documentation as a standard part of a slab leak call, since it's the piece homeowners most often need when they file.
This isn't insurance advice, and coverage terms vary by policy and carrier, so confirm the specifics with your own insurer before assuming a claim will be approved.
Slab Leak Risk by Carrollton Housing Era
Carrollton's population jumped from about 1,600 residents in 1950 to nearly 14,000 by 1970, and most of the housing built during that stretch used galvanized steel for supply lines, the standard material of the era. Those lines run directly under the slab in a lot of these homes, and galvanized pipe corrodes from the inside out over decades, a process Carrollton's hard water speeds up by adding mineral scale on top of ordinary rust.
Homes built from the 1980s onward generally moved to copper, and more recent construction near the TX-121 corridor typically uses PEX. Both are more resistant to the kind of internal corrosion that drives galvanized slab leaks, though copper can still develop a pinhole leak under the right water chemistry conditions.

Frequently Asked Questions
If a hot-water line has developed a leak under the slab, the water heater has to keep reheating water that's continuously escaping and being replaced by cold water from the supply line. That extra cycling is sometimes the earliest sign of a slab leak, showing up before a warm floor spot or a bill spike does.
A warm or hot patch on an otherwise normal floor, especially over a spot with no nearby appliance to explain it, is one of the more reliable signs of a hot-water line leaking under the slab. A cold-water line leak won't produce warmth, so it tends to show up instead as dampness or warped flooring.
It depends on the leak's location and how accessible it is. We'll walk through both options, spot repair through the slab or rerouting the line above it, and the tradeoffs of each before you decide.
Many policies cover sudden, accidental water damage but exclude damage from gradual leaks or wear. Insurers typically want documentation of when the leak was discovered and a plumber's leak-detection report, so keep both on hand when you file a claim.
The EPA estimates that undetected household leaks waste roughly 10,000 gallons of water a year on average, and a slab leak that goes unnoticed for months can push well past that.
We can re-run the acoustic leak detection independently rather than starting from the earlier report, since a leak that's hard to pinpoint sometimes needs a second pass or a different listening point to narrow down.
Where the leak sits, and whether a spot repair or a reroute makes more sense, both drive the number, so that's worked out once the leak is actually located.
Call and we'll let you know what's available. A suspected slab leak with a climbing water bill or a hot water heater that won't stop running is the kind of call worth treating with urgency rather than waiting.
