RiverCity Plumbing specializes in slab leak repair in Jacksonville, FL, offering non-invasive tunneling and pipe rerouting as alternatives to open-slab demolition. A warm spot on tile, the sound of running water with all fixtures off, or an unexplained water bill spike are the three most common slab leak indicators in Mandarin (32223) and Southside (32246) homes, where monolithic slab construction leaves no crawlspace access. Tunneling reaches the leaking pipe through a narrow tunnel dug under the foundation from outside the home, leaving your flooring untouched; rerouting runs a new supply line through the walls or attic to bypass the failed section entirely. Electronic detection typically takes 2–4 hours to precisely locate the leak, a reroute is completed in 1–2 days, and tunneling in 2–3 days. We provide detailed documentation of the leak location, cause, and repair method — the format insurance adjusters require in Duval County. Call (904) 760-7837.
Slab Leak Repair Jacksonville FL
Fix the Leak the Right Way — Without Destroying Your Home
A slab leak is a pressurized water line failure beneath your concrete foundation, and in slab-on-grade neighborhoods like Mandarin (32223) and Southside (32246) there is no crawlspace to work from — every repair path starts at the marked leak location. Jacksonville’s 15.3 GPG hard water corrodes under-slab copper from the inside, so when one section has failed, the rest of the run is often in similar condition. That’s why we quote repair options, not just a single fix.
Haven’t confirmed the leak yet? Start with our non-invasive slab leak detection in Jacksonville — acoustic, thermal, and pressure-isolation testing that marks the exact leak position before any repair decision is made.
Your Slab Leak Repair Options
Spot Repair Through the Slab
The most direct fix: we open a small, precisely placed section of concrete directly above the marked leak, repair the pipe, pressure-test the line, and re-pour the concrete. Best when the leak is isolated and the surrounding pipe is in sound condition. Where the leak sits near the foundation perimeter, tunneling under the slab from outside can reach the pipe without touching interior flooring at all.
Overhead Reroute
We run a new supply line through the walls or attic space to bypass the failed under-slab section entirely. Your floors are never touched, and the corroded run under the concrete is abandoned in place — it can never leak on you again. This is usually the right call when the leak is centrally located under the home or the existing copper is extensively corroded.
Epoxy Lining — What to Know Before You Choose It
Epoxy lining coats the inside of an existing pipe rather than replacing it. It has a legitimate place in larger drain lines, but for the small-diameter pressurized supply lines under a slab we generally advise against it: copper that has corroded to the point of pinhole leaks rarely makes a sound host pipe for a liner. If you are weighing a lining quote from another company, we are happy to give you a straight second opinion.
When a Repipe Beats a Repair
If your home has already had one slab leak, if the line shows corrosion along its length, or if you have gray polybutylene supply pipe (common in Jacksonville homes built from the late 1970s through the mid-1990s), repairing one failure at a time becomes a losing game. A whole-home repipe or polybutylene replacement replaces the failing system once, on your schedule, instead of leak by leak on the pipe’s schedule.
What a Slab Leak Repair Visit Looks Like
- Confirm the marked location. We verify the detection findings and walk you through each viable repair method with a clear quote for each before anything is opened.
- Protect the home. Floor coverings and dust containment go up before any concrete or drywall is touched.
- Access and repair. Slab opening, tunnel, or wall/attic access depending on the method chosen — then the pipe repair or new line installation.
- Pressure test. Every repair is pressure-tested and verified before anything is closed up.
- Close and restore. Concrete re-pour for slab access, wall patching for reroutes. Where the City of Jacksonville requires a permit for the work, we pull it and coordinate the inspection.
Concrete Re-Pour & Flooring Restoration
For slab-access repairs, we pour new concrete flush with the existing slab, and the patch needs its cure time before flooring goes back down. We handle the plumbing and the concrete; finished flooring reinstallation is coordinated with your flooring installer so tile, wood, or carpet goes back over a fully cured, verified-dry slab. For reroutes, restoration is limited to patching the wall or ceiling access points.
Insurance Documentation Included
We provide detailed written reports documenting leak location, cause, pipe material, and repair method in the format required by Duval County homeowner’s insurance adjusters — including before-and-after photos and pressure test confirmation.
