Leak Detection

Leak detection is how we find hidden water leaks behind walls, under floors, or underground without tearing your home apart to look. Listening equipment, thermal imaging, and meter testing narrow a leak to a small, specific spot before anyone picks up a saw. If your water bill jumped and your habits didn't, this is usually the right first step.

What's included

  • A walkthrough of your home and a look at recent JEA or utility bills
  • Water meter testing to confirm whether water moves with every fixture off
  • Acoustic listening equipment that hears water escaping a pressurized pipe
  • Thermal imaging to spot temperature differences behind walls and floors
  • Pressure testing to isolate which section of supply line is losing water
  • A plain-language summary of where the leak is and your repair options

Signs it's time to schedule

Your water bill jumped and you can't explain it

A sudden spike with no change in habits is one of the most reliable signs water is escaping where you can't see.

You hear water running when everything is off

A faint hiss behind a wall or under the floor, with every fixture off, points to a pressurized line losing water.

The water meter moves with all fixtures shut

If the dial keeps ticking when nothing is using water, something is drawing it continuously.

Musty smells or soft spots you can't trace

Damp odors, cupping floorboards, or bubbling paint low on a wall often appear before any visible water does.

When does it make sense?

Schedule leak detection when the evidence says water is going somewhere it shouldn't, but you can't see where: an unexplained bill increase, a meter that moves on its own, or a damp spot with no source. There's a check you can do first: turn off everything that uses water and watch your meter for 20 to 30 minutes. No movement means a constant leak is unlikely; movement confirms a leak but not its location — the part our equipment answers, at your convenience.

The Jacksonville angle

Jacksonville homes hide leaks well. Most First Coast houses sit on concrete slabs, so supply lines run where you'll never see a drip, and the first symptom is often a JEA bill that doesn't add up. Humidity complicates things too: summer condensation on cold pipes gets mistaken for leaks constantly, and part of our job is telling those apart honestly. Older Riverside and Springfield homes develop pinholes in aging copper and galvanized lines; newer PEX homes in Nocatee tend to leak at fittings.

How we handle it

  1. 01

    Tell us what you're seeing

    Call or message us with the symptoms: the bill, the sound, the spot. It helps us arrive with the right equipment.

  2. 02

    We test and pinpoint

    We confirm the leak with meter and pressure testing, then narrow it to a specific location with acoustic and thermal tools.

  3. 03

    You get the findings and a quote

    We show you the evidence, explain the options, and give an upfront written quote before any repair begins.

  4. 04

    Repair and walkthrough

    If you'd like us to make the repair, we open only what's needed and walk you through the finished work.

Why homeowners pick us for leak detection

  • We pinpoint before anything gets opened: one small access point at the leak, not exploratory holes across your wall.
  • We show you the evidence — meter readings, thermal images, what we heard — so you're deciding on facts.
  • We'll walk you through the DIY meter test by phone. If you can rule out a leak yourself, we'd rather save you the visit.
  • Detection and repair under one roof, so nothing gets lost between finding the problem and fixing it.

FAQ

Leak Detection — your questions

How do plumbers find leaks without tearing open walls?
Plumbers locate hidden leaks with acoustic listening equipment, thermal imaging, and pressure testing, so the wall only gets opened at the one spot where the repair happens. Escaping pressurized water makes a distinct sound microphones pick up through drywall and concrete, and thermal cameras spot the temperature change a leak creates.
How can I tell if my high water bill in Jacksonville is from a leak?
Turn off every faucet, appliance, and irrigation zone, then watch your water meter for 20 to 30 minutes; if it keeps moving, water is leaving your plumbing somewhere. The test is free and we encourage it first — though a leaky toilet flapper or irrigation issue can pass it and still inflate a JEA bill.
How much does leak detection cost?
The cost depends mostly on how hard the leak is to reach: under a slab or out in the yard takes more time and equipment than behind an accessible wall. Rather than guess, we take a look, give you a free estimate, and put the price in writing before any work starts.
Can I have a water leak with no visible water anywhere?
Yes, and most hidden leaks we find never show a visible drop. Water under a slab drains into the soil, and a buried line can lose water for months into Jacksonville's sandy ground without a puddle forming. That's why the meter test and your bill are better indicators than your eyes.
Is the moisture on my pipes a leak or just Jacksonville humidity?
Often it's condensation, not a leak: in our humid climate, cold water lines sweat, especially in summer. A leak stays in one spot regardless of weather and usually comes with a moving meter or rising bill. If you're unsure, we'll tell you straight, even if the answer is that nothing needs fixing.
