Leak Detection Services in Los Angeles & Orange County
Power Pro Plumbing, Heating & Air finds hidden water leaks, including slab leaks, across Los Angeles and Orange County, pinpointing the source with electronic listening equipment, pressure testing, and thermal imaging instead of tearing your house apart.
Slab leaks deserve special mention in Southern California: since our homes sit on concrete slab foundations rather than basements, supply lines often run under or through the slab, and a pinhole leak there can quietly erode soil, damage flooring, and spike your bill. Precise detection matters most exactly there — the difference between opening one small access point and jackhammering blind.
Once we've located the leak, we'll walk you through repair options on the spot, from a targeted pipe repair to rerouting a failing line. Ask about $50 off leak detection when you book.

What are the signs of a hidden leak?
Any of these signs can point to a hidden leak, so call for leak detection if you notice them:
- A water bill that jumps without any change in household usage
- The sound of running water when every fixture is off
- Warm spots on floors (a classic hot-water slab leak sign)
- Mold, mildew, water stains, or a persistent musty odor
- Low or dropping water pressure at fixtures
- Cracks in the slab or flooring that keep spreading
How does professional leak detection work?
Professional leak detection starts by confirming a leak exists — typically with a meter test that isolates your plumbing from the house. Then we narrow it down: acoustic equipment listens for the distinct sound of water escaping under pressure, thermal cameras reveal temperature differences behind walls and under floors, and pressure testing isolates which line is losing water.
The payoff of professional leak detection is precision. Instead of exploratory demolition, we open exactly one spot — and most detections take one to three hours start to finish.
What are your options after a leak is found?
Leak repair options range from a simple spot repair to rerouting a line or a full repipe, because not every leak calls for the same fix. A single failed fitting may need a simple spot repair. A slab leak often makes more sense to reroute overhead through walls and the attic rather than opening the foundation. And if we find one pinhole in a corroded copper or galvanized system, we'll be honest about whether more are coming — sometimes a repipe is the fix that actually ends the problem.
Leak Detection FAQs
How much does leak detection cost? +
It varies with the complexity and location of the leak, but we quote the price upfront before starting — and we currently offer $50 off leak detection. Catching a leak early nearly always costs far less than repairing the water damage from a late catch.
Is leak detection covered by homeowner's insurance? +
Many policies cover leak detection and access costs when a leak has caused property damage, though coverage varies. We recommend checking with your carrier; we can provide the documentation they typically ask for.
What is a slab leak and why are they common here? +
A slab leak is a leak in a water line running beneath or within your home's concrete foundation. SoCal homes are built on slabs (no basements), so supply lines routinely run under the concrete — and decades of hard water and soil movement eventually wear pipes out. Warm floor spots and unexplained bill spikes are the classic tells.
Will you have to tear up my floors to find the leak? +
No — that's the whole point of electronic detection. We pinpoint the leak location first, then open only the small access needed for the repair. For slab leaks, a reroute can often avoid opening the slab entirely.
