A hidden leak can run for months behind a wall, under a slab, or out in the yard — quietly rotting framing, feeding mold, and driving your water bill up. The good news is that a leak leaves clues, and with acoustic and electronic detection equipment we can pinpoint the source before anyone opens a wall or breaks concrete.
Riverside Plumbing Pros finds and repairs supply-line leaks, pinhole leaks in aging copper, fixture and valve leaks, irrigation-line leaks, and slab leaks. We use pressure testing and leak-location tools to separate a real plumbing leak from condensation or a roof issue, and we keep the repair as targeted as possible.
If a leak has already caused damage, act fast — the EPA's guidance is to address clean-water damage within 24 to 48 hours to limit mold. Shut off the water if you safely can, photograph everything before cleanup for your insurance, and call us for triage.
Warning signs of a hidden leak
- A water bill that jumped with no change in usage
- The water meter moving when everything is turned off
- Warm or damp spots on the floor (a possible slab leak)
- The sound of running water when no fixtures are on
- Musty odor, staining, or bubbling paint on walls or ceilings
- Low water pressure across the whole house
What's included with leak detection & repair in Riverside
Every leak detection job is scoped in writing before we start, and the price you approve is the price you pay. Here's what a standard visit covers:
- Meter check and pressure test to confirm a leak exists and roughly where
- Acoustic and electronic detection to pinpoint the source before any wall is opened
- The smallest possible access opening — or a reroute that avoids demolition entirely
- A written scope separating the plumbing repair from drywall and restoration work
- The repair, followed by a re-test to confirm the leak is gone
- Photos and documentation for your records or an insurance claim
Our leak detection process
- 1
Verify there's a leak
We check the meter and pressure-test the system to confirm a leak exists and roughly where it's losing water.
- 2
Pinpoint the source
Acoustic and electronic equipment locates the leak precisely so we open the smallest possible area — no exploratory demolition.
- 3
Written repair options
We explain the fix and separate the plumbing repair scope from any drywall, flooring, or water-damage restoration.
- 4
Repair & verify
We make the repair, re-test pressure to confirm the leak is gone, and document the work for your records or insurer.
Leak repair cost in Riverside
A published Riverside range for a faucet or supply-line leak repair is about $212–$310, with broader small-repair guidance of $140–$570. Slab and concealed leaks vary with access. Leak detection can save far more than it costs by preventing unnecessary demolition.
Faucet / supply-line repair: ~$212–$310 (planning range)
What affects your price:
- Whether the leak is exposed, in a wall, or under the slab
- Detection method and access required
- Pipe material and whether a section needs replacement
- Separating plumbing repair from restoration scope
- Emergency vs. scheduled timing
