A static pressure test on each line tells us whether you are losing water — and whether it is the hot side, the cold side, or a drain line. No guessing, no assumptions.
Acoustic ground microphones pick up the exact sound of pressurized water escaping a pipe — even through concrete. This is how slab leaks get located within inches.
Thermal imaging cameras reveal the warmth of a hot-line leak spreading through a slab or wall — a visual map of where the water is traveling.
For pinhole leaks that barely whisper, tracer gas (a safe hydrogen-nitrogen mix) is pushed into the line and sniffed out at the surface — accurate where sound alone is not enough.
The leak gets marked on the floor, you get written findings plus a clear repair price — spot repair, reroute, or lining — before any work begins.
How it works
High bill, hot floor spot, sound of running water, damp drywall — whatever tipped you off, we start there.
Pressure tests, acoustic listening, thermal imaging — layered methods until the leak gives up its exact position.
Written findings, marked location, and a clear repair price. The detection report is yours to keep either way.
Emergency service
A pressurized leak can push hundreds of gallons a day into your slab and walls. Every hour of waiting is more water damage, more mold risk, and a bigger repair bill.

Local knowledge
Whittier grew up in the post-war decades, and much of its housing stock still runs on the original copper and galvanized supply lines — run under concrete slabs, exactly where slab leaks start. Add hard Southern California water and decades of soil movement, and pinhole leaks become a when-not-if problem for 1950s–1970s homes from Uptown to the East Whittier tracts.
That age-of-pipe reality is why detection-first matters here. Ripping up a slab on a guess can mean thousands in unnecessary concrete work; acoustic and thermal location narrows the opening to a surgical square. We see the same failure patterns street after street — and we know where to listen first.
The ground itself is part of the story. Whittier sits at the foot of the Puente Hills, and parts of the city sit on potentially expansive clay soils — ground that shrinks through nine dry months and swells with winter rain. That annual shrink-swell cycle works under-slab copper loose a fraction at a time, year after year. And if your pipes predate October 1987, they have already lived through the Whittier Narrows earthquake: a magnitude 5.9 that shook the city at Mercalli Intensity VIII and broke water and gas mains across town. Joints that survived severe shaking do not always age gracefully.
Then there is the water itself. Whittier’s supply runs hard — typically 10 to 15 grains per gallon depending on your provider and zone — and the city is served by multiple purveyors, including the City of Whittier Water Department and Suburban Water Systems, so hardness varies street to street (check your water bill to see which one serves you). Hard water lays mineral scale inside pipes, creating pressure points where pinhole leaks develop. Put it together — expansive soil, quake history, hard water, and era-specific pipe: pre-1940s galvanized in the Uptown historic districts, 1950s–70s copper under slab in the Friendly Hills and Murphy Ranch tracts — and you get a city where leak patterns are predictable if you know where to look.
Common questions
The classic signs: a hot spot on the floor, the sound of running water when nothing is on, a water bill that jumps for no reason, damp carpet or buckling flooring, and your water meter spinning with all fixtures off. Any one of these is worth a professional leak detection visit — slab leaks do not fix themselves and the water damage compounds daily.
Pros use non-invasive methods: acoustic listening equipment that hears pressurized water escaping a pipe, thermal imaging cameras that spot temperature differences from leaking hot lines, static pressure tests that confirm which line is losing pressure, and tracer gas for pinhole leaks. The goal is to pinpoint the leak within inches so any opening in the slab or wall is small and surgical.
In the Whittier area, professional leak detection typically runs $200–$600 depending on the method needed and how hidden the leak is. Slab leak location with acoustic and thermal equipment sits in the middle of that range. The repair itself is quoted separately once the leak is pinpointed — detection first, then a clear written price for the fix.
Yes — it is the simplest homeowner test. Turn off every fixture and water-using appliance, then watch the meter (most have a small leak-indicator dial or triangle). If it moves at all over 15–30 minutes, water is going somewhere it should not. That confirms a leak exists; professional equipment then finds exactly where.
Treat it as urgent. A pressurized supply-line leak under a slab can push hundreds of gallons a day into the soil and foundation — eroding soil, cracking the slab, and feeding mold inside walls. A drain-line leak is slower but still damages flooring and framing. Either way, every day of waiting raises the repair bill.
Much of Whittier’s housing stock went up in the 1950s–1970s with copper and galvanized supply lines run under concrete slabs. Decades of hard water, soil movement, and normal pipe aging wear those lines thin — pinhole leaks and slab failures are the predictable result. It is an age-of-pipe problem, not a homeowner’s fault.
Often, sudden and accidental water damage is covered, though every policy differs. Most policies cover the resulting water damage (flooring, drywall) and sometimes the access cost to reach the leak, but not always the pipe repair itself or long-term seepage. We document everything with photos and readings so you have what your adjuster needs.
Both. Detection pinpoints the leak; then you get a clear written price for the repair — a spot repair, a reroute overhead, or epoxy lining depending on the pipe’s condition. You approve the fix before any work starts, and the detection findings are yours to keep either way.
Most residential visits take 1–3 hours. A straightforward slab leak with acoustic equipment is on the shorter end; a mystery leak that needs pressure testing plus thermal imaging plus tracer gas takes longer. You get findings the same visit — no waiting days for lab results.
