Leak Detection & Repair in Carrollton, TX
A hidden slab or wall leak can run for months before it shows up as a warm spot on the floor or an unexplained jump in the water bill.
Call (831) 666-1222Most 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 rarely an obvious puddle to point to.
Instead, the signs tend to be indirect: a water bill that jumps for no clear reason, a warm patch on the floor if it's a hot water line, or the sound of running water when every fixture in the house is off. Carrollton's hard water adds another wrinkle, since mineral buildup inside older galvanized lines can eventually corrode through the pipe wall from the inside out.
Signs of a Hidden Leak
Because slab and wall leaks are hidden by design, most homeowners notice one of a handful of secondary symptoms first.
Common signs of a hidden leak
- ✓A noticeably higher water bill with no change in usage
- ✓A warm or damp spot on an otherwise normal floor
- ✓The water meter still spinning when every tap and appliance is off
- ✓A musty smell in one part of the house with no visible source
- ✓Cracks in flooring or baseboards near a plumbing wall
How We Find a Leak Without Guessing
Electronic leak detection equipment listens for the specific sound water makes escaping a pressurized line, which lets us narrow down a leak's location without opening up walls or flooring on a hunch.
Once the leak is located, the repair itself depends on where it is and what the line is made of. Some slab leaks are more practical to reroute above the slab than to access and repair in place, and we'll walk through both options honestly rather than defaulting to the more invasive one.
| Leak Location | Common Repair Approach |
|---|---|
| Slab leak, accessible line | Direct spot repair |
| Slab leak, hard to access | Reroute the line above the slab |
| Wall leak | Access panel repair, matched to the wall material |
| Older galvanized line, general corrosion | Often a candidate for full repipe rather than a single spot fix |
When a Leak Points to a Bigger Repipe Job
If a home is still running its original galvanized supply lines, one confirmed leak is sometimes a sign that other sections of pipe are close behind it. In that case, we'll say so directly instead of just patching the one spot and leaving the rest of the system to fail piecemeal over the following year.
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. Galvanized pipe corrodes from the inside out over decades, and Carrollton's hard water accelerates that process 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 materials resist the kind of internal corrosion that causes galvanized pipe to fail, though copper can still develop pinhole leaks under the right water chemistry conditions.
None of this means a newer home is leak-proof, but it does change what we look for first. In an older home, we're checking galvanized runs and their joints. In a newer one, we're more likely looking at a single damaged fitting or a spot where a nail or screw pierced a line during some other renovation.

Frequently Asked Questions
Electronic leak detection listens for the sound of water escaping a pressurized line, which narrows the location down closely enough that any opening we do make is targeted rather than exploratory.
It depends on the leak's location and how accessible it is. We'll walk through both options and the tradeoffs of each before you decide.
Yes, mineral buildup inside older galvanized pipe can corrode through the pipe wall over time, which is more common in Carrollton given the local water hardness.
A jump in your water bill with no change in usage, a warm spot on the floor, or a water meter that keeps moving with everything off are the most common signs.
Yes, when a home's galvanized lines are failing broadly rather than in one isolated spot, a full repipe is often the more practical long-term fix.
