Why this comes up in Pomona
Pre-war craftsman and 1920s bungalows around Lincoln Park frequently still run galvanized water lines and cast iron drains that are past their service life. On slab-built streets around Lincoln Park, a pinhole under the concrete can run for months before it shows up as anything but a higher bill.
The expensive part of a hidden leak is guessing. We pinpoint it with acoustic listening, pressure isolation and thermal imaging, then fix or reroute.
Detection is quoted separately from the repair, so you know what finding it costs before you commit to fixing it.
Signs it is time to call
- Water bill jumped with no change in use
- Warm spot on a tile or vinyl floor
- Sound of running water with everything shut off
- Cracks in slab or damp baseboards
- Mildew smell in one specific room

Leak detection & slab leaks questions from Pomona customers
Do you have to jackhammer the floor?
Not always. Rerouting the line overhead or through a wall is often cheaper and less disruptive than opening the slab. We price both options.
How do you confirm the leak is really under the slab in Pomona?
We isolate the system, pressure test it, and use acoustic equipment to pinpoint the spot. You see the readings, not just a conclusion.
Will my insurance cover it?
Many policies cover the resulting water damage rather than the pipe itself. We document the findings clearly so you can file with real evidence.
