How do I know if I have a slab leak?

Common signs include unexplained warm or hot spots on the floor, the sound of running water when no fixture is in use, a sudden spike in the water bill, low water pressure throughout the home, mildew or musty smells, and visible water seeping through baseboards or floor cracks. Any combination of these warrants a call, and our team can confirm with detection equipment without cutting any concrete first.

How does Roland Black find a slab leak without cutting the floor?

We use acoustic listening devices that can hear the sound of pressurized water escaping a line, plus thermal imaging that shows temperature differences from a hot-water leak under the floor. Combined, these methods locate slab leaks within inches of the actual source. Cutting concrete only happens after the leak is precisely located, which keeps the repair targeted and the floor damage minimal.

What are my repair options for a slab leak?

The three main options are spot repair at the leak location, line rerouting that bypasses the leaking section by running new pipe through walls and ceilings, and full repipe of the affected line. The right choice depends on the leak location, the condition of the rest of the line, and the homeowner's budget. Our team walks through the trade-offs honestly during the assessment.

Will homeowner's insurance cover a slab leak repair?

Insurance coverage varies, and most policies cover the resulting damage but not the leak repair itself. Some policies include separate coverage for the access work required to reach the leak. Our team documents the leak location, the diagnostic process, and the repair work in detail so homeowners have what they need to file a claim. Specific coverage questions should always be confirmed with the insurance carrier directly.

How long does slab leak repair take?

Most slab leak repairs are completed in one to two days from detection through repair, depending on the chosen repair method and the leak's accessibility. Spot repairs are typically completed faster, while full line reroutes can take longer because of the additional plumbing work. Concrete restoration, if needed, is handled separately and may extend the timeline.

Slab Leak Repair in Gastonia, NC

A slab leak happens when a water supply line under your home’s concrete foundation springs a leak, and the damage compounds while it goes undetected. Hot spots on the floor, an unexplained jump in the water bill, and the sound of running water when no fixture is in use are the classic signs-and the longer they go uninvestigated, the more flooring and concrete get drawn into the repair. Roland Black has been finding and fixing slab leaks in Gastonia and Gaston County since 1973, using non-invasive detection equipment to pinpoint the leak precisely before any concrete is touched. If the leak turns out to be elsewhere in the system, our leak detection team handles broader diagnostics across the home.

Slab Leak Detection Beats Guessing Where to Cut

Slab leaks used to mean cutting concrete in a likely-looking spot and hoping. Modern detection equipment locates the leak within inches before any concrete is touched, which saves the homeowner money on the repair and minimizes the scope of restoration work afterward. The Environmental Protection Agency’s Fix a Leak Week resource covers the broader water-loss math, and slab leaks specifically can waste thousands of gallons before the homeowner even notices.

Common Slab Leak Issues We See in Gastonia

Slab leaks come from a handful of root causes, and the right repair depends on which cause is at work. Here are the three most common slab leak issues we see across Gaston County, with our diagnostic and repair approach for each.

Pinhole leaks in copper supply lines are the most common slab leak we encounter, and they result from a combination of water chemistry, line age, and soil conditions. Once one pinhole forms, more often follow on the same line. Our team locates the active leak with detection equipment and discusses whether spot repair, rerouting, or replacement of the affected line makes the most sense given the line’s overall condition.

Hot water lines under slabs experience more thermal stress than cold lines, and they tend to leak first. Hot side leaks are also more visible to detection equipment because of the thermal imaging signature. We track hot water leaks specifically through proper detection procedures and address them with the same repair options as cold side leaks, though the thermal stress on the hot side often points toward rerouting rather than spot repair.

Foundation movement can pinch supply lines under the slab, eventually causing the line to fail at the pinch point. This category of slab leak is harder to repair with simple spot repairs because the cause is structural rather than wear-related. Our team identifies structural causes during the assessment and discusses whether rerouting around the affected area is the more reliable long-term solution.

Roland Black handles every part of slab leak detection and repair across Gastonia and Gaston County, from the first call through final restoration coordination.

Non-invasive leak detection uses acoustic listening and thermal imaging to locate slab leaks within inches.
Spot repair access cuts a targeted opening directly over the leak rather than guessing.
Line rerouting bypasses leaking sections by running new pipe through walls and ceilings, which avoids further concrete work.
Full line repipe replaces the entire affected supply line when the rest of the line is also at risk.
Hot and cold side leaks are both addressed, since slab leaks can affect either side of the supply.
Pinhole leaks in copper lines are common and are repaired with appropriate fittings or replacement.
Documentation is provided for insurance claims, including detection results and repair specifications.

Additionally, every repair is tested under pressure before sign-off, with our lifetime workmanship guarantee on labor and extended warranty options on installed parts. Contact us today to learn more about Gastonia slab leak repair service.
