Find underground irrigation line and valve leaks fast — pinpoint sprinkler system failures without trenching the whole yard.
If your irrigation system is running constantly, your water bill is climbing, or you've spotted soggy spots in the lawn between sprinkler runs, you have an underground irrigation leak. Sawgrass Construction Solutions Leak Detection pinpoints irrigation leaks using pressure testing, electronic listening, and zone isolation so we can fix the leak without trenching your entire yard.
The most reliable signs of an irrigation leak are a high water bill with no indoor explanation, soggy or unusually green spots in the lawn, sprinkler heads that drip when the system is off, low pressure in one or more zones, or the controller cycling longer than scheduled. If you see any of these, schedule a leak inspection before water and money keep running.
We isolate each irrigation zone individually, pressure-test the supply lines, and use electronic listening to pinpoint the exact location of any leak underground. For larger main line breaks, the leak is often visible. For smaller lateral or fitting failures, pinpoint accuracy lets us repair with minimal digging.
Most irrigation leak detection jobs run $300-$550 depending on system complexity and number of zones. We provide a flat-rate quote upfront. If we identify the leak but can't pinpoint it with standard methods (rare), we explain alternative options before any additional charges.
Typical jobs are completed in 1.5 to 2.5 hours. We arrive with all equipment, run through every zone, and walk you through what we found before leaving. Repair work, if needed, can usually be scheduled for the same week.
Yes. Sawgrass handles both detection and repair — replacing damaged lines, fittings, valves, or backflow preventers. We restore the lawn area we dig and you don't have to schedule a separate landscaper for the irrigation fix.
Sawgrass has 40+ years of irrigation experience across Duval, St Johns, and Clay counties. We know which subdivisions use reclaimed water (and the sediment issues that come with it), which builders used PVC vs poly lateral lines, and where common fitting failures occur.

Schedule a Leak DetectionOur disciplined process prevents unnecessary work and ensures clarity at every stage.
We walk the property looking for soggy areas, exposed lines, or visible drips that immediately reveal the leak location.
Each irrigation zone is activated individually so we can identify which zone holds the leaking line.
We pressure-test the suspect zone's supply line to confirm a leak is present and gauge its size.
Ground microphones pinpoint the leak's exact location underground, often within inches.
The leak location is flagged for spot repair, minimizing how much sod or landscaping needs to be disturbed.
How much can an irrigation leak waste?
A single 1/8-inch hole in a pressurized irrigation line can waste over 6,000 gallons per month. Larger main line breaks can double or triple a typical water bill in a single billing cycle.
Do you work on reclaimed water systems?
Yes. Many Northeast Florida subdivisions use reclaimed water for irrigation, and we're experienced with the specific sediment, valve, and backflow issues that come with reclaimed systems.
Can you find a leaking sprinkler valve?
Yes. Failing diaphragms and stuck solenoids cause valves to leak even when off. We test each valve and replace failing components on the spot when possible.
