Pinpoint leak location before any digging — acoustic and infrared detection from a licensed C-36 crew.
A slab leak is a water line leaking beneath your home's concrete foundation, usually signaled by an unexplained spike in your water bill, a warm spot on the floor, or the sound of running water when everything is off. It should be treated as urgent: left unaddressed, it can undermine the foundation and cause serious structural and mold damage. Until we arrive, shut off the main water supply if the leak is significant and avoid running water unnecessarily.

Slab leaks are quiet damage — the water is out of sight, so the leak often runs for weeks before anyone notices the water bill, a warm patch on the floor, or a faint hissing sound. South Gate's seismic exposure makes this a real local risk: ground shift from even minor tremors stresses rigid pipe joints beneath older foundations, and homes built in the 1950s-70s often still have original copper or galvanized lines under the slab. The longer a slab leak runs, the more water works into the foundation soil, which can lead to settling, cracked flooring, and mold growth — damage that costs far more to repair than the leak itself.
We locate the leak precisely before any concrete is touched, using acoustic listening equipment to hear the sound signature of pressurized water escaping underground, combined with infrared thermal imaging to spot temperature differences in the slab caused by the leak. Once pinpointed, we discuss repair options: a direct spot repair through a small access point, or trenchless repiping that reroutes the line above the slab or through a lining process — avoiding a full foundation excavation wherever the leak location allows it.
Licensed California C-36 plumbers trained in acoustic and infrared leak detection — not guesswork or exploratory demolition.
We factor South Gate's seismic activity and foundation soil conditions into every slab leak diagnosis and repair plan.
Trenchless repair options considered first, to minimize the cost and disruption of breaking up concrete.
South Gate sits in an earthquake-active region, and even minor seismic activity stresses rigid pipe joints under a concrete slab over time — a factor that's less relevant in newer, more flexible piping systems but very real in homes built before 1980 with original copper or galvanized lines. Add in the area's clay-heavy soil, which shifts with moisture changes, and slab leaks are a recurring issue across older South Gate blocks. We factor this seismic and soil context into every leak diagnosis, not just the plumbing itself.
The most common signs are a water bill spike with no change in usage, a warm spot on the floor, the sound of running water with everything off, or unexplained cracks in flooring. A licensed plumber can confirm with a water meter test and detection equipment.
Cost depends on leak location and whether a spot repair or trenchless reroute is possible versus a section requiring more extensive access. We provide a specific quote after detection pinpoints the exact leak location — we don't estimate blind.
Yes. Prolonged water intrusion into foundation soil can cause settling, shifting, and cracked flooring. That's why we treat suspected slab leaks as urgent rather than something to monitor.
Coverage varies by policy and whether the damage is considered sudden or gradual. We recommend confirming directly with your insurance provider; we can supply documentation of the leak and repair for your claim.
Acoustic detection listens for the specific sound of pressurized water escaping through the slab. Infrared thermal imaging detects temperature variations in the floor caused by the leak. We use both together for the most accurate location.
Not usually. Once the leak is precisely located, many repairs only require a small access point, or the line can be rerouted above the slab entirely, avoiding large-scale demolition.
