A hidden leak under your floor can run for months before you notice it. Our leak detection plumber team finds the exact source beneath slab foundations across Orange County and fixes it with as little damage to your home as possible.
Slab leaks are hard to spot because the pipe sits under concrete. The first signs are often a water bill that jumps for no clear reason or a warm patch on the floor. You may also hear water running when every faucet is off. By the time flooring lifts or baseboards stain, the leak may have soaked the area for weeks.
Precision Plumbing handles slab leak repair from the first test to the final patch. As a foundation leak repair plumber, our focus is fixing the pipe while protecting the concrete and floors above it. We open only the small area needed for access, or route around the slab when that makes more sense. Before leaving, we pressure test the line to confirm the leak is fully sealed.

Finding a leak under concrete by guesswork can mean breaking open the wrong part of your floor. Water often travels along a pipe or through the gravel bed before it surfaces, so the wet spot is not always above the leak. Every unnecessary cut adds cost, dust, and flooring repairs. Accurate location is what keeps the repair small.
Our technicians use acoustic listening equipment to hear water escaping under the concrete. We pair this with thermal imaging to trace hot water lines and pressure testing to confirm which line is leaking. Together, these tools narrow the leak down to a small section of floor. You get a clear plan before any concrete is touched.

Detection equipment comes before opening the floor. Pressure testing and electronic listening help narrow the leak location so the repair starts with a defined area rather than a guess.
Precision Plumbing brings more than 26 years of plumbing experience to slab leak work. That experience matters when pipe condition, access, flooring, and the location of an underground leak all influence the repair.
Breaking concrete is not the only possible approach. Some homes are better suited to rerouting the affected line through an accessible area, while others make targeted slab access more practical. Pipe condition and the existing layout guide that decision.
Existing tile, hardwood, and other finishes are not always easy to match after access work. The potential impact on flooring is discussed before the repair so you know what the plumbing work involves.

The plumbing system is checked to determine whether it is losing water when fixtures are closed. Pressure testing can help identify whether the loss involves a particular section or side of the system.
Electronic listening equipment and other detection methods help narrow the leak location. The goal is to identify a practical access point before concrete is disturbed.
The affected pipe is repaired or rerouted according to the condition and layout. The plumbing is then tested to check the repair before the work is considered complete. Concrete and flooring restoration follow according to the agreed scope.
Many Orange County homes have copper water lines running under the slab. When one section fails, other sections of the same age are often close behind. Hard water and constant contact with concrete wear these pipes down over time. Fixing one leak after another can mean opening your floors again and again.
Rerouting takes the leaking line out of the slab and runs new pipe through the walls or attic instead. We usually use flexible PEX, which needs fewer fittings and holds up well against hard water scale. This approach leaves your floors untouched and retires the old line for good. If several lines show wear, we can discuss whole house repiping as a longer term solution.
Many newer tract homes in Orange County sit on post tension slabs. These foundations contain steel cables pulled tight inside the concrete. Cutting into one of these cables can damage the foundation and cause serious injury. That makes leak work in these homes riskier than in a standard slab.
Before any cutting, we locate the cables with scanning equipment and mark their position on the floor. We then plan the access point to stay clear of the cables and the anchors near the slab edges. When the risk is too high, rerouting the line becomes the safer choice. Your foundation stays protected while the leak gets fixed.
Some slab leaks do not stay small. A broken hot water line can push water up through tile grout, soak carpets, and keep your water heater running nonstop. Damp drywall and flooring can also start growing mold quickly. Waiting for a regular appointment may lead to much larger repairs later.
When water is coming up through the floor, our team responds fast. We isolate the leaking line so the rest of the house can keep running water, then locate and fix the break. If the leak kept your heater running for days, we check whether it needs water heater repair after the strain. The water gets stopped first, and a lasting repair follows right after.

Most slab leaks start when copper pipes wear thin from hard water, corrosion, or rubbing against concrete and gravel. Shifting soil, high water pressure, and poor original installation can also stress the pipes. Over time, these factors create pinhole leaks or cracks beneath the foundation.
Turn off every faucet, appliance, and irrigation line, then look at your water meter. If the dial or small leak indicator keeps moving, water is escaping somewhere in the system. A plumber can then use slab leak detection tools to confirm whether the leak is under the slab.
Yes, if it runs long enough. Constant water can wash away soil under the slab or cause clay soil to swell, which leads to cracks and uneven floors. Fixing the leak early helps prevent this kind of structural damage.
The cost depends on how deep the pipe sits, what flooring covers it, and whether the line is repaired directly or rerouted. Direct repairs under tile or hardwood often add flooring costs, while reroutes add drywall patching. An accurate estimate requires locating the leak first.
Detection usually takes a few hours. A direct repair is often finished in a day, while a reroute can take one to two days depending on the length of the line. Flooring or drywall repairs may add time after the plumbing work is done.
