Meter test first
The meter is watched with all taps closed. A meter that moves points to a supply leak; a meter that holds points elsewhere, and that distinction saves needless opening.
Hidden-leak detection for slab and wall leaks in Cerritos homes

About this service
What leak detection means in a slab-on-grade Cerritos home
Leak detection is the work of locating a supply leak that cannot be seen: meter checks, pressure and isolation testing, and acoustic listening, used in combination. No single method proves a leak on its own; together, they narrow the section until the repair can be kept small.
Cerritos homes are commonly slab-on-grade, with a median year built of 1974 and about 83% built before 1980, and ageing in-slab copper is a familiar source of hidden leaks. A leak under a slab does not flood a room the way a burst fixture line does; it warms a floor, lifts a tile, or feeds a bill. Detection therefore starts with the meter and the pattern of symptoms, not with opening floors.
- ✓Meter check with everything closed
- ✓Isolation to narrow the section

- ✓Repair kept as small as the diagnosis allows
What's included
What a leak detection visit includes
A detection visit is a narrowing exercise. Each check removes part of the house from suspicion, until the leak's section is the only part left.
Isolation by section
Supply sections are isolated in turn, so the leak is narrowed to a run of pipe rather than left as a whole-house suspicion.
Acoustic listening
Listening equipment helps pinpoint a leak within the narrowed section, so any opening is placed where the leak actually is.
Drain versus supply separation
Drain and sewer symptoms are separated from supply symptoms, because a damp patch can come from either, and the repair differs completely.
Plain-language findings
You are told what was tested, what each test showed, and where the leak sits, so the repair discussion starts from evidence.
Watch points for Leak Detection
Where Leak Detection work reveals a neighbouring problem, it is pointed out plainly, so a later visit starts from a clear record rather than a surprise.
How it works
How leak detection works
Warm floor, damp patch, musty smell, moving meter, or rising bill, and when each first appeared. The pattern already narrows the search.
The meter is checked with everything closed, and pressure is checked to confirm a supply leak and its character.
Supply runs are isolated in turn until the leaking section is identified and the rest of the house is cleared.
Listening equipment narrows the leak within that section, so any opening is placed precisely.
Findings are explained, the leak's section is marked, and the repair options for that section are discussed.

Tools & methods
Tools and methods used for leak detection
Water meter observation
The first and simplest test: a meter that moves with everything closed points to a supply leak.
Pressure testing equipment
Confirms a supply leak and helps separate one section from another during isolation.
Acoustic listening equipment
Hears a leak within a narrowed section, so an opening is placed where the leak is.
Thermal checking
Helps map warm areas on a floor where a hot-water slab leak is suspected.
Drain camera
Separates a drain or sewer cause from a supply cause where damp could come from either.
Moisture checking
Maps how far damp has spread, which matters for both repair and drying.

Leak Detection
Older tract homes in Greenbrook
Greenbrook, in the oldest Cerritos wave, is where in-slab copper age and mature landscaping combine.
Common approach: A detection visit there starts with the meter and isolation, because opening a floor on a guess is the most expensive mistake in a slab home.

Larger lots in Shadow Park mean longer supply runs, which makes isolation by section more valuable: each isolated run removes a longer length from suspicion at once.

Leak clues we investigate in Cerritos
These clues are the usual reasons a Cerritos homeowner calls for detection. None of them, on its own, proves a leak; together, they build the case for testing.
Ask a pro →Warm patch on a floor
A warm area on a slab floor commonly points to a hot-water supply leak under the slab, and listening and isolation narrow it.
Meter moving with taps closed
A meter that turns when nothing is running points to a supply leak somewhere in the system, and isolation finds its section.
Damp, musty, or stained areas
Damp at a skirting board or a musty smell can come from supply or drain. The checks separate those causes before any opening.
Bill rising without explanation
A bill that jumps without a change in use is a reason to test the meter and isolate sections, not a reason to assume a fixture fault.

A meter check with all taps closed. If the meter moves, a supply leak is likely; if it holds, the cause is more likely a drain, a fixture, or a non-plumbing source, and the investigation follows that result.
Detection itself is non-invasive: meter, pressure, isolation, and listening checks narrow the leak before any opening. Any opening that follows is placed where the leak has been pinpointed, not where it was guessed.
Cerritos homes are commonly slab-on-grade with ageing in-slab copper, and that combination commonly produces pinhole leaks over time. The leak shows as a warm floor, damp, or a rising bill rather than as a visible burst.
The section is marked, findings are explained, and repair options for that section are discussed, including repair in place and rerouting around the slab where that fits the section and the home.
