Most leak detection calls do not start with someone saying the word leak. They start with a water bill that jumped for no clear reason, or a water meter that keeps spinning even with every fixture in the house turned off. Both are signs of a leak somewhere in the line, even when nothing is visibly wet.
Why Hidden Leaks Are Common In Altadena Homes
Many Altadena homes were built decades ago on slab foundations with copper supply lines run underneath the concrete. Copper pipe under a slab has a working life, and once a pinhole develops, water can travel along the slab and surface far from the actual leak point.
Soil movement adds to the problem. Altadena sits on a mix of clay, sandy loam, and adobe soils in the San Gabriel Valley foothills, and seasonal moisture changes shift that soil enough to stress buried pipe joints over time.
Signs You Have A Hidden Leak
Rising Water Bill
A bill that climbs without a change in household water use is one of the most reliable leak signals we see.
Meter Still Spinning
Turn off every fixture and check your water meter. If the dial keeps moving, water is leaving the system somewhere.
Warm Spot On The Floor
A warm patch on tile or concrete flooring often points to a hot water line leaking under the slab.
Sound Of Running Water
Hearing water movement with every fixture off is a classic sign of a pressurized line leak.

How We Find A Leak Without Tearing Up The Yard
Electronic leak detection starts with acoustic listening equipment that picks up the sound pressurized water makes escaping a pipe, even through concrete or soil. That narrows the search area before anything gets opened up.
For a suspected slab leak, we combine acoustic tracing with a pressure test on isolated sections of the line. Thermal imaging can also flag a hot water leak by showing the warm plume it creates under flooring, which is faster than guessing based on the warm spot alone.
Any repair, reroute, or repipe follows Uniform Plumbing Code (UPC) requirements for pipe material, sizing, and support, the same code that governs new plumbing installation anywhere in California.
What Does It Mean If My Water Bill Went Up?
Fixing The Leak Once It Is Found
Spot Repair
If the leak is isolated to one accessible section of pipe, a direct repair is usually the fastest and least invasive option.
Reroute
For a slab leak, rerouting the line through a wall or attic instead of the slab avoids cutting concrete entirely.
Repipe
A home with multiple leaks on aging copper may be a better candidate for a full repipe than repeated spot repairs.
What Affects The Cost Of Leak Detection
Scope Of The Problem
A straightforward, isolated repair costs less than a job involving multiple fixtures or a harder-to-diagnose root cause.
Parts & Materials
Fixture quality, pipe material, and whether a part needs to be special-ordered all factor into the final price.
Access & Location
A repair behind a finished wall, under a slab, or in a hard-to-reach crawlspace takes longer than one with open access.
Timing
Standard daytime scheduling costs less than an after-hours or weekend emergency dispatch.
Homeowner's insurance often covers sudden, accidental damage like a burst pipe, but typically does not cover gradual wear, an aging part failing on its own, or deferred maintenance. Check your specific policy for what it actually covers before assuming either way.
These factors explain why prices vary. For your exact number, call (626) 898-6169 and describe what you're seeing, we'll give you a flat price before any work begins.
Common Questions
My water meter is running even with everything off. What does that mean?
It means water is escaping the system somewhere between the meter and your fixtures. That is exactly the scenario electronic leak detection is built to trace.
Do I need to dig up my yard to find a leak?
Not usually. Acoustic and pressure-based detection narrow the leak's location first, so excavation, when needed, is targeted instead of exploratory.
Is a slab leak an emergency?
A slab leak will not always flood a home immediately, but it can cause real structural and mold damage over weeks. Prompt diagnosis limits that damage.
What To Check Before You Call
- Write down your water meter reading, wait two hours with no water use in the house, then check it again. A meter that moved confirms an active leak and helps us gauge its size.
- Check your last two water bills side by side if you have them. A jump of more than a few dollars with no change in household habits is useful evidence to share with the technician.
- Note whether the warm spot or sound is constant or comes and goes with specific fixtures. That detail helps narrow whether the leak is on the hot or cold side of the system.

Water Heater Repair: If the acoustic trace points back to the water heater connections rather than the supply line, that becomes a water heater repair instead of a slab leak.
A rising bill or a running meter is worth a call before it becomes a bigger repair. Electronic leak detection finds the source first, so the fix matches the actual problem.
