RiverCity Plumbing

A hidden water leak is one of the most damaging things that can happen to a Jacksonville home and most homeowners don't notice one until it's already caused mold, structural damage, or a water bill that's doubled overnight. At River City Plumbing, we use advanced leak detection equipment to find leaks fast without tearing apart your walls or floors and fix them right the first time.
Warning Signs You May Have a Water Leak in Jacksonville
Jacksonville's humid climate, sandy soil, and aging pipe infrastructure make hidden leaks more common here than in most U.S. cities. If you notice any of these warning signs, call us immediately:
-
Unexplained spike in your monthly water bill
-
Damp spots, stains, or discoloration on walls, ceilings, or floors
-
Mold or mildew smell especially in bathrooms or under sinks
-
Sound of running water when all fixtures are turned off
-
Low water pressure throughout the house
-
Warm or soft spots on your floor (common sign of slab leak)
-
Wet patches in your yard with no recent rain
-
Cracks appearing in walls or your home's foundation
Don't ignore these signs. A slow leak left untreated leads to mold growth, rotting subfloor, and foundation damage. If your drains are also backing up, see our drain cleaning service.

Why Jacksonville Homes Are Especially Vulnerable
Several factors unique to Northeast Florida make plumbing leaks more likely here than in most parts of the country:
Hard Water & Pipe Corrosion
Jacksonville's water supply carries high levels of calcium and magnesium minerals. Over time, this mineral-rich water causes scale buildup inside copper pipes, slowly corroding them from the inside out. The result is pinhole leaks that are nearly invisible until they've already soaked your walls or subfloor. Homes in Riverside, San Marco, and Avondale where older copper lines are common are especially at risk.
Sandy Soil & Shifting Foundations
Jacksonville's geography is largely sandy soil. When heavy rains hit and with 52+ inches of rainfall a year, they hit often the soil shifts beneath your foundation. This movement puts constant stress on the pipes running under your slab, causing them to crack or separate at joints over time. Slab leaks are one of the most common calls we receive from homeowners in Arlington, Northside, and Orange Park.
Aging Infrastructure in Older Neighborhoods
Homes in Avondale, Springfield, Riverside, and San Marco were built decades ago with iron or copper pipes that are approaching or past their lifespan. Salt air corrosion near Jacksonville Beach, Atlantic Beach, and Neptune Beach accelerates pipe degradation further. If your home is over 30 years old and you've never had a plumbing inspection, a hidden leak is a real possibility.

We use non-invasive technology to locate leaks precisely – no unnecessary digging, no tearing open walls without cause. Our licensed Jacksonville plumbers handle every type of leak, from minor fixture drips to major underground line failures.
Slab Leak Detection & Repair in Jacksonville
A slab leak a pipe leak occurring beneath your concrete foundation is one of the most serious plumbing problems a homeowner can face. Left unaddressed, slab leaks erode soil beneath your foundation, cause cracks in walls and flooring, and lead to mold colonies forming under your slab.
Signs you may have a slab leak:
Warm spots on your floor (hot water line leak)
Sound of water running under the floor
Sudden drop in water pressure
Foundation cracks appearing without explanation
Water meter moving when all fixtures are off
We use acoustic listening devices and thermal imaging to locate slab leaks precisely before we ever break ground minimizing disruption to your flooring and foundation.
Underground Water Line Leak Detection
A leak in the service line running from the city water meter to your home can saturate your yard, cause sinkholes, and significantly increase your water bill. These leaks are invisible buried underground and require professional detection equipment to find.
If your water bill has spiked and you see wet patches in your yard, call us for an underground line inspection. We can pinpoint the exact leak location and repair or replace the line efficiently.
Wall & Ceiling Leak Detection
Water traveling through walls from a second-floor bathroom, leaking pipe joint, or roof-adjacent plumbing can cause stained ceilings, peeling paint, and if ignored long enough rotting structural beams. We use moisture meters and thermal imaging cameras to find exactly where water is entering without opening up walls unnecessarily.
Pinhole & Copper Pipe Leak Repair
Jacksonville's hard water is the leading cause of pinhole leaks in older copper pipes. These microscopic cracks are nearly impossible to spot visually, but our acoustic detection tools can hear them. We repair individual pinhole leaks or, where pipe corrosion is widespread, recommend repiping sections to permanently solve the problem.
Fixture & Under-Sink Leak Repair
Leaking faucets, toilet supply lines, garbage disposal connections, and under-sink drain fittings are the most common and most ignored leaks in Jacksonville homes. A single dripping faucet wastes thousands of gallons per year. We fix all fixture leaks on the spot.
If your faucet or toilet needs full replacement, see our faucet & toilet replacement service.
Outdoor & Pool Area Pipe Leaks
Outdoor hose bibs, irrigation lines, and pipes running to pool equipment are exposed to Jacksonville's intense heat, humidity, and UV rays accelerating wear faster than indoor pipes. We inspect, detect, and repair outdoor plumbing leaks, including those affecting sprinkler systems and outdoor kitchens.

Inspection & Assessment
We start with a full walkthrough of your plumbing system, checking all visible fixtures, supply lines, and drain connections while asking you about any symptoms you've noticed.
