Why slab leaks happen in this area
- 01Copper against concreteLines cast directly into the slab in mid-century Cerritos tracts abrade and corrode at every contact point.
- 02Hard water and pinholesAggressive water thins copper from the inside until a pinhole opens, usually on the hot line first.
- 03Soil movementExpansive soil shifting under the foundation stresses rigid pipe until a joint or bend fails.
We diagnose first, then you choose
Once we've marked the leak, you have real options: open a small area and repair the spot, or reroute the line overhead and leave the slab alone. Both are legitimate, and which is better depends on the pipe's overall condition — which detection also tells us.
Detection and spot repair
Best when the rest of the piping is sound and the leak is a single failure point.
See slab leak repairDetection and reroute
Best when the under-slab line has failed before, or access is under finished flooring you'd rather not open.
From your call to a marked spot on the floor
- 01
Tell us the symptoms
Warm floor, high bill, running sound — each narrows where we start listening.
- 02
Isolate and pressure test
We isolate hot and cold to confirm which line is losing water, then quote the detection in writing.
- 03
Pinpoint electronically
Listening equipment and line tracing narrow the leak to a marked spot, not a general area.
- 04
Explain your options
You get the location, the likely cause, and written prices for spot repair versus reroute.
You'll see the number before we start
Detection is quoted as its own step so you're not committing to a repair before you know where the leak is. What affects it:
- Size of the home and how much piping has to be isolated and tested.
- Flooring type — tile and hardwood change how sound transmits and how long location takes.
- Whether both hot and cold systems need testing.
- Whether you also want the sewer line cameraed to rule it out.
“They found the slab leak exactly where they said it was, opened one small area, and the final invoice matched the quote.”
Questions we get on the phone
The classic combination is a warm spot on the floor, a water bill that jumped, and the sound of running water with every fixture off. Any one of those is worth a call before the soil under the foundation is affected.
