Question 1

How much does leak detection cost in Phoenix?

Accepted Answer

Electronic leak detection in Phoenix costs $150–$500 depending on the complexity and equipment needed. Basic acoustic detection for a suspected slab leak location: $150–$300. Full electronic sweep including thermal imaging, acoustic listening, and tracer gas for difficult leaks: $300–$500. This cost is typically credited toward the repair if you proceed with us. Emergency after-hours leak detection carries a premium. Prices are 2026 Phoenix metro averages.

Question 2

What types of leak detection do you use?

Accepted Answer

We use three primary methods depending on the situation. Acoustic detection uses sensitive microphones to hear the frequency signature of pressurized water escaping a pipe — effective for supply line slab leaks. Thermal imaging detects temperature anomalies on floors and walls where water is cooling or warming the surface. Tracer gas (helium or nitrogen) is injected into the pipe and detected at the surface with a gas sensor — most accurate for elusive leaks. Most slab leaks require a combination of acoustic and thermal methods.

Question 3

My water bill spiked but I can't find any visible leak — what do I do?

Accepted Answer

A water bill spike with no visible leak usually means the leak is underground or behind a wall. First, do this: read your water meter, wait 2 hours without using any water, read it again. If the meter moved, you have an active leak somewhere. In Phoenix, the most likely location is under the slab (slab leak) or in your irrigation system. Turn off the irrigation shutoff and repeat the test — if the meter stops moving with irrigation off, you've isolated it to irrigation. If not, call for professional leak detection.

Question 4

Can you detect leaks without opening walls or floors?

Accepted Answer

Yes — that's the whole point of electronic leak detection. Acoustic sensors and thermal cameras locate leaks from the surface in most cases. We use the detection data to pinpoint the leak location within inches before any cutting or jackhammering. This precision matters especially in Phoenix homes with post-tension slabs (where cutting in the wrong location damages structural cables) and in finished spaces where minimizing damage is critical.

Question 5

How do I know if I have a slab leak vs. an irrigation leak?

Accepted Answer

The isolation test is straightforward: find the irrigation shutoff valve (usually near your backflow preventer at the side or back of the house), turn it completely off, then check your water meter for movement. If the meter stops moving, the leak is in your irrigation system. If the meter still moves with irrigation off and all interior fixtures off, the leak is in your house plumbing — likely a slab leak. A plumber with electronic detection equipment can confirm the exact location.
