If you can see or hear water moving right now, that is urgent and worth calling about today. If the only sign is a bill that quietly crept up, there is no need to panic; a hidden leak that has already run for weeks will still be there tomorrow, and finding it right matters more than finding it in the next hour.
The point of leak detection is to open one small hole in the right place instead of several in the wrong ones. Gilbert's plumbing is mostly copper and PEX from the master-planned building era, and the classic failure here is a pinhole in copper, driven by years of hard, mineral-rich water working on the pipe wall from the inside. Those leaks hide inside walls, above ceilings and under the slab, where the only early sign is a bill that climbed for no reason.
We find the leak first and dig second. Acoustic listening equipment, pressure isolation and thermal imaging let us narrow a leak to a specific run of pipe, so the repair is targeted rather than exploratory.
The signs Gilbert homeowners usually call about
When it is worth a detection visit
Any one of these is a reason to check:
- A water bill that rose with no change in how much you use
- The water meter dial creeping when every fixture is off
- A warm or damp patch on a tile or wood floor
- The sound of running water in a wall with nothing turned on
- Loss of hot-water pressure, which often points to a hot-side slab leak

First we confirm the leak is real and on your side of the meter, then isolate whether it is on the pressurized supply, the drain side, or the irrigation system, because each is found a different way. For supply leaks we pressure-test and listen; the escaping water makes a sound that travels through the pipe and the slab, and acoustic gear picks up where it is loudest.
Thermal imaging helps most with hot-side slab leaks, where warm water under the floor creates a temperature signature we can see through tile. On the drain side, a camera does the finding. The goal every time is a specific spot marked on the floor or wall before anyone opens anything.
| Leak location | What you notice | Detection method |
|---|---|---|
| Pinhole in wall copper | Stain or bubble on drywall | Pressure test plus acoustic |
| Hot-side slab leak | Warm floor, hot-water pressure drop | Thermal plus acoustic |
| Irrigation or hose bib | Wet ground, bill up in summer | Isolation at the valve manifold |
| Drain or sewer | Smell, slow drains, damp | Camera inspection |
Why Gilbert copper develops pinholes
Hard water leaves scale, and the same mineral chemistry that scales a water heater slowly attacks copper from the inside over many years. Homes plumbed in the 1990s and 2000s are now old enough that the first pinholes are showing up, often several within a couple of years of each other because the whole system aged together. One pinhole is a repair; a pattern of them is a conversation about
repiping, which we get into on the repiping page rather than overselling a single fix.
Gilbert questions about leak detection
Can you find a leak without breaking anything?
Detection itself is non-destructive. We use pressure testing, acoustic listening and thermal imaging to pinpoint the spot, so the only opening made is the one needed for the actual repair. That is the whole reason to detect before digging.
My bill doubled but I see no water anywhere. Is that a leak?
Very likely, and often a hidden one. A slab leak or an underground irrigation leak can run for weeks with no visible water inside the house while it quietly drives the bill up. The meter test is the quickest confirmation: shut everything off and watch whether the dial still moves.
Do you detect irrigation and pool leaks too?
Yes. In Gilbert a summer bill spike is as often the irrigation system or a pool line as it is indoor plumbing. We isolate the irrigation manifold from the house supply to tell which side is losing water before chasing it further.
What happens once you find the leak?
Where detection leads next
Detection is the front door to several repairs. Once located, a pressurized leak under the floor becomes slab leak repair, a failed wall line becomes pipe repair, and a house full of aging copper becomes a repiping decision. If the trouble turns out to be on the drain side, sewer camera inspection takes over the finding. Left alone, a hidden leak is the leading cause of the water damage calls we run across Gilbert and Tempe Junction.
