Plumbing Leak Detection
Whole-house plumbing leak detection — supply lines, drain lines, hot water systems, and hidden wall leaks.
Schedule an AppointmentIf your water bill jumped without explanation, you hear water running when nothing is on, or you've spotted a damp wall or ceiling, you have a hidden plumbing leak. Sawgrass Construction Solutions Leak Detection uses electronic listening, thermal imaging, and pressure testing to find plumbing leaks anywhere in your home — without cutting open walls or floors.
How do I know if I have a hidden plumbing leak?
The most common signs of a hidden plumbing leak are an unexplained spike in your water bill, the sound of running water when no fixture is on, damp drywall or ceilings, warm spots on tile floors (slab leaks), or musty smells. If you notice any of these, get it inspected before structural damage spreads.
- Unexplained increase in monthly water usage
- Sound of running water when nothing is on
- Wet drywall, ceiling stains, or peeling paint
- Warm spot on a tile or concrete floor
- Musty smell or visible mold growth
- Water meter spinning with all fixtures off
How does plumbing leak detection work?
We start by isolating the leak to a section of the system: hot or cold supply, main drain, hot water heater, irrigation, or fixture. From there we use electronic listening (a microphone tuned to the frequency of pressurized water escaping), thermal imaging (especially effective for hot-water slab leaks), and tracer gas where needed. The result: a leak pinpointed to within inches before any wall is opened.
What does plumbing leak detection cost?
Most plumbing leak detection jobs run $350-$650. The exact price depends on system complexity and whether multiple isolation points need testing. We quote a flat rate upfront and stand behind it — no hourly billing surprises and no charge if we can't locate the leak with standard methods.
How long does plumbing leak detection take?
Most jobs are completed in 1.5 to 3 hours on site. We arrive with all equipment, perform the diagnosis, and walk you through the findings before leaving. Same-day appointments are available for emergency leaks where water damage is actively occurring.
Why choose a local Northeast Florida plumbing leak company?
Sawgrass has 40+ years of plumbing experience across Duval, St Johns, and Clay counties. We know which neighborhoods have galvanized supply lines, which were built with cast-iron drains, and which subdivisions used PEX manifolds — local pattern knowledge that cuts diagnosis time.
Our Process: What to Expect
Our disciplined plumbing leak detection process prevents unnecessary work and ensures clarity at every stage.
Water Meter Test
We confirm the leak by reading your water meter with all fixtures off — any movement confirms an active leak somewhere in the system.
System Isolation
Hot, cold, and individual fixture lines are isolated one at a time to narrow the leak to a single section before pinpointing.
Electronic Listening
Specialized ground microphones detect the high-frequency sound of pressurized water escaping a pipe under floors or behind walls.
Thermal Imaging
For hot water leaks especially, thermal imaging cameras show temperature anomalies through walls and slabs without any cutting.
Pinpoint and Mark
We mark the exact leak location on your wall, floor, or slab so any repair work is targeted — minimizing demolition.
Plumbing Leak Detection — FAQ
How accurate is electronic plumbing leak detection?
Our electronic listening and thermal imaging methods typically pinpoint leaks within a 6-inch radius, often closer. That accuracy minimizes how much wall, floor, or slab needs to be opened for the repair.
Will you need to cut into walls to find the leak?
No. Our entire detection process is non-invasive — no drywall cutting, no slab breaking. Cutting only happens if you choose to proceed with repair, and only at the exact spot we've marked.
Can you find a leak under a concrete slab?
Yes. Slab leaks are one of our most common service calls. Electronic listening and thermal imaging are both highly effective for locating leaks under concrete without breaking the slab to find them.
