Irrigation Leak Detection & Underground Pipe Repair
Wet spots in the lawn, soggy mulch beds, or a water meter that never stops spinning — we find and repair underground leaks fast, with minimal landscape damage.
Irrigation Leak Detection & Pipe Repair in Miami
Underground irrigation leaks are one of the most expensive sprinkler problems homeowners ignore. A single hairline crack on a lateral line can waste hundreds of gallons a day, drive up your water bill, drown out plant roots, and undermine pavers or foundations. By the time you see a soggy spot, the leak has usually been running for weeks.
Locating the leak is the hard part. Lateral lines and mainlines run under turf, beds, and hardscape. We use pressure isolation, zone-by-zone testing, and visual indicators (wet spots, sinkholes, vegetation patterns) to narrow the leak down before we ever break ground.
Once located, most repairs require only a small dig — typically 12–24 inches across — to expose the pipe, cut out the damaged section, and splice in a clean repair with proper PVC fittings. We restore the dig site before we leave.

Common Problems We Solve
Sound familiar? Here's what we usually find — and how we fix it.
Wet spot in the lawn that won't dry
Almost always a cracked lateral line or a leaking fitting. We isolate the affected zone, narrow down the location, and dig only where needed.
Water meter spins with the system off
Indicates a mainline leak — the line under constant pressure between the meter and the valves. These leaks waste the most water and need fast repair.
Geyser when a zone runs
A broken riser or shattered head body. Visible above ground and a quick fix, but watch for repeated breaks in the same spot — usually a lawnmower-height issue we can solve permanently.
Sunken paver or sinkhole near a zone
A long-running underground leak has eroded the soil. Repair the pipe, then backfill and re-set the affected hardscape.
Our Process
Same approach on every job — diagnosis first, then fix.
Pressure-test by zone
We isolate which zone or mainline section is losing pressure to narrow the search area.
Locate the leak
Visual inspection, ground probing, and listening tools to pinpoint the leak before digging.
Repair & splice
Cut out the damaged section, splice in new PVC or poly with proper fittings and primer/cement, pressure-test the repair.
Restore the site
Backfill, replace turf or mulch, and run the zones to verify the fix. Labor is backed by our 1-year warranty.
Frequently Asked Questions
About leak detection in Miami-Dade & Broward.
How much does irrigation leak detection cost?
Diagnosis is included in our free estimate. Repair pricing typically runs $150–$350 for a standard lateral-line repair, depending on depth, access, and pipe size. Mainline repairs cost more due to the higher pressure and pipe size.
How do I know if I have an underground irrigation leak?
Common signs: a wet or soggy area of lawn that doesn't dry, a water meter that turns when nothing is on, an unexplained jump in your water bill, low pressure on one zone, or a sinkhole/depression near the irrigation lines.
Will you tear up my lawn to find the leak?
No. We pressure-test and isolate the leak before digging, then dig only the area needed for the repair — usually a square foot or two of turf. We restore the area before we leave.
Can a leak cause a high water bill?
Absolutely. A single mainline leak can waste several thousand gallons a month. If your water bill suddenly doubled or tripled with no usage change, an irrigation leak is the most common cause.
