904 Plumbers connects you with a licensed Jacksonville plumber who pinpoints a hidden leak with electronic acoustic detection for $150–$450 — before anyone opens a wall or slab. A spiking JEA bill, a warm floor, a soggy yard: the leak gets located to within inches, then the repair is quoted upfront across Duval, Clay and St. Johns.
The clearest sign of a hidden leak is a JEA bill that jumps with no change in habits. Back it up with the meter test: turn off every water fixture in the house, then watch the water meter for 15 minutes — if the dial or leak indicator still moves, water is escaping somewhere between the meter and your fixtures.
Other tells: the sound of running water when nothing is on, a warm spot on a tile or slab floor, unexplained mildew or a musty smell, cracked or lifting flooring, or water pressure that’s quietly dropped. Any one of these is worth a look before the leak finds drywall, cabinets, or your foundation.
Professional leak detection finds the leak without tearing up your house. The plumber confirms the leak with a meter and pressure test, then pinpoints it with electronic acoustic listening equipment that hears water escaping under concrete or behind walls, plus line tracing and thermal imaging where needed. The result is an X on the exact spot — not a guess and a jackhammer.
That precision is the whole point. Older “find it by digging” methods destroy slabs, walls, and landscaping to chase a leak. Electronic detection isolates the failure to within inches first, so the repair is small and targeted — the difference between opening one floor tile and demolishing a room.

Leak detection in Jacksonville runs $150–$450 for electronic acoustic pinpointing. A basic meter-and-pressure test to confirm a leak is $100–$200; locating a slab or underground supply-line leak with acoustic equipment is $150–$450; and irrigation or main-line locating $150–$400. Detection is billed separately from the repair, and many plumbers credit it toward the fix.

Against a leak wasting thousands of gallons a month — or soaking into your slab — detection pays for itself fast. You get the location and a repair quote before any digging.
In Jacksonville, hidden leaks concentrate in five places: under the slab (aging copper and polybutylene supply lines), in the irrigation system, on the buried main service line from the meter, inside walls behind fixtures, and around pool equipment and lines. Slab and irrigation leaks are the most common — and the easiest to miss until the bill arrives.
The metro’s housing stock drives it. Slab-on-grade homes from the 1970s–90s ran copper and polybutylene under the foundation, both of which pinhole and split with age. Irrigation is nearly universal here and runs underground where a cracked line or stuck valve leaks unseen for months. Detection sorts out which system is losing water so you’re not repiping the house when it’s a $200 sprinkler fix — or ignoring a slab leak because you blamed the sprinklers.

Run the meter test: shut off every fixture, then watch the water meter for 15 minutes — if it still moves, you have a leak on your side of the meter. A spiking JEA bill, a warm floor spot, the sound of running water, or a musty smell are the other common signs worth a professional look.
Yes — that’s the entire point of electronic leak detection. Acoustic listening equipment, pressure testing, and line tracing isolate the leak to within inches before anything is opened. That turns a repair from demolishing a room into lifting one tile or opening a small section of wall.
Leak detection is the diagnostic step that finds and pinpoints any hidden leak — slab, wall, irrigation, or main line. Slab leak repair is the fix for a leak specifically under the concrete foundation. Detection comes first and tells you which repair you actually need, so you don’t pay to fix the wrong thing.
Not always — but a sudden jump with no change in usage almost always is, and in Jacksonville the culprit is often an irrigation line or a running toilet. Detection confirms whether water is escaping and where, so you know before spending on a repair. JEA’s 2026 rate increase can also raise a bill without any leak at all.
