A leak you can't see is still a leak we can find.
Hidden leaks waste water and damage homes. Straight Flush finds them with acoustic, electronic, and thermal diagnostics — owner-operated in Laguna Niguel, where Lance answers the phone and we diagnose before recommending repair or repipe.
What is water leak detection?
Water leak detection uses specialized equipment — acoustic listening devices, electronic pipe locators, and thermal imaging cameras — to identify precisely where a leak is occurring inside walls, under floors, or underground, without needing to open up the entire area first.
It's the diagnostic step that should always happen before a repair quote. Skipping it is how homeowners end up with unnecessary drywall or slab demolition that misses the actual leak.
- Rising water bill with no change in usage
- Water meter still spinning with everything off
- Sound of running water behind a wall or under a floor
- A warm spot on flooring (possible hot water slab leak)
- Dropping water pressure
- Damp carpet, bubbling floors, or a musty smell
Three detection methods, matched to your situation
Sound-Based Detection
Sensitive listening equipment picks up the distinct sound of pressurized water escaping a pipe underground or inside a wall cavity.
Infrared Imaging
Thermal cameras detect temperature differences caused by moisture or hot water leaks beneath flooring, invisible to the naked eye.
Electronic Locating
Sensor-based tracing follows the exact path of a pipe, narrowing down the access point to a precise, small area.
How a leak detection visit actually works
Consultation
We discuss your symptoms and history with the property.
Visual Inspection
We check all accessible plumbing and fixtures first.
Pressure Testing
Isolating which line and zone is involved.
Technology Locating
Acoustic, thermal, or electronic tools pinpoint the source.
Findings & Options
We explain what we found and your realistic options.

We isolate the system with pressure testing, then use acoustic listening equipment to hear the sound of escaping water, thermal imaging to spot temperature changes from hot-water leaks, and electronic locating to trace the pipe's path. That narrows the leak to a small, specific area before any wall, floor, or concrete is opened, so any access needed stays as small as possible.
General leak detection covers leaks anywhere in the system, including walls, ceilings, fixtures, and under floors. Slab leak detection is the same diagnostic approach focused on pressurized water lines running beneath a concrete foundation, where acoustic and thermal tools pinpoint the leak without breaking up the slab.
Coverage depends on your policy and the cause of the loss. Many policies address the resulting water damage rather than the plumbing repair itself. We document what we find so you have clear evidence for a claim, and our insurance resources cover what to ask your provider.
Cost depends on the type of leak, how deep it sits, and how accessible the plumbing is, which is why we diagnose before quoting any repair. Lance will walk you through what to expect for your specific situation, and our leak detection cost guide explains the factors that affect price.
Once we have located it, we explain what we found and your realistic options, including spot repair, reroute, or repipe, and why one may make more sense than another for your home. No repair is recommended before you understand the diagnosis.
