Leak Detection in Torrance, CA
Electronic and acoustic leak tracing finds slab leaks, hidden pipe leaks, and the source of an unexplained high water bill, without guessing where to dig or cut.
Signs you have a hidden leak
Water bill spiked with no change in use
If your usage habits haven't changed but the bill has climbed, a hidden leak is one of the most common causes.
Warm spot on the floor
A warm patch on a slab floor, especially near the water heater, often points to a hot-water line leaking under the concrete.
Sound of running water
Hearing water movement in the walls or under the floor when every fixture is off is a classic leak signal.
Meter still moving with everything off
If your water meter keeps ticking with all fixtures and appliances shut off, water is escaping somewhere in the system.
Not sure where the leak is?
We can usually pinpoint it before opening anything.
Why leak detection matters more in Torrance
Torrance's mix of housing eras means leak causes vary by neighborhood. Older Old Torrance and Walteria homes are more likely to have aging copper or galvanized supply lines nearing the end of their service life, while homes closer to the coast see faster corrosion on exposed fittings from marine-layer humidity and salt-laden air.
Because Los Angeles County water is naturally hard, mineral buildup can also mask a small leak for longer by slowing the drip before it becomes visible, which is part of why an unexplained bill increase is often the first real sign homeowners notice.
How we find a leak without guesswork
Meter and pressure check
We start by confirming water is actually being lost through the system rather than a billing or usage issue.
Electronic and acoustic tracing
Ground microphones and electronic tracing equipment listen for the specific sound of pressurized water escaping underground or in a wall.
Thermal and moisture checks
For slab leaks, thermal imaging and moisture readings help narrow the leak's exact location before any concrete is opened.
Confirm before repair
We mark the confirmed leak location and walk through repair options before any cutting or digging starts.
"My water bill went up and I don't know why"
Many Torrance homeowners call us not because they've spotted a leak, but because something feels off: a bill that doesn't match usage, a meter that won't stop turning, or a vague sense that water is going somewhere it shouldn't. That's exactly what leak detection is for; you don't need to already know where the leak is for us to find it.
It means water is escaping somewhere between the meter and your fixtures, even if nothing is visibly wet yet. That's a strong reason to schedule leak detection before the leak grows or starts causing damage.
Yes. Most leak detection calls start exactly this way. Electronic and acoustic tracing don't require you to know the source in advance.
The cost of leaving a hidden leak alone
A slow leak rarely stays small. Water finding its way into a slab or wall cavity over weeks or months can undermine a foundation, feed mold growth, and damage flooring or drywall well beyond the plumbing itself, turning a leak-detection call into a much larger restoration project if it goes unaddressed.
We also get commercial calls for this, from small Torrance businesses and property managers dealing with an unexplained utility bill increase or a suspected slab leak under a commercial floor. The diagnostic approach is the same as a residential call, though access and shutoff points are usually different in a commercial building.
Clear pricing before work starts

Questions about leak detection in Torrance
Usually, yes. We use electronic and acoustic detection to narrow the location before any concrete is opened.
Most residential leak detection calls are completed in a single visit, though slab leaks in larger homes can take longer to fully trace.
If detection doesn't confirm an active leak, we'll walk you through other possible causes for a high bill, such as a running toilet or irrigation system.
Yes, including commercial leak detection for Torrance business properties, with the same electronic and acoustic tracing methods used residentially.
