Hot + coldLeak Detection in Aliso Viejo
Finding a leak is not the same as fixing one, and it is the half of the job where the most damage gets done by guesswork. Aliso Viejo Plumbing Pros treats detection as its own discipline: listen, measure, and confirm before anything is opened.
We use acoustic listening, thermal imaging, meter isolation, and pressure testing to put a tight circle around the failure, and the street log to decide where to look first, because in this city the same floor plans hide their leaks in the same places.
Insured. Free estimates. Upfront written pricing. Same‑day service on most calls.

Hidden leaks we locate
Slab leaks under concrete, pinhole leaks inside walls, drips traveling along framing to show up rooms away from their source, irrigation and yard line failures, and the quiet toilet and valve leaks that inflate a water bill without leaving a mark.
What you get
A located leak, shown to you before we cut. A written explanation of what failed and why. Repair options with upfront pricing, from a single access opening to a reroute. And if we find the water is coming from something that is not a plumbing failure at all, we tell you that too and charge you for nothing.
From the street log
Several Aliso Viejo floor plans route a hot line under the hallway between kitchen and garage. When a homeowner reports a warm hallway floor and a bill jump, the log usually names the line before the listening gear confirms it.
Questions
Leak Detection: common questions
- My water bill jumped. Is that a leak?
- Usually one of three things: a running toilet, an irrigation failure, or a slab leak. Ten minutes with the meter narrows it down, and we will tell you over the phone how to do that check yourself for free.
- Do you have to cut open walls to find a leak?
- No. Location happens from the outside with listening and imaging equipment. Cutting happens once, at the confirmed location, for the repair itself.
- How precise is the location?
- Typically within a tile or two. The point of paying for detection is that the repair opens one small spot instead of following a guess across the floor.
