Leak Detection & Repair — Good Catch Plumbing

Coastal-grade work, done right.

A small leak can quietly drive up your water bill and rot your home from the inside long before you see a stain. We use non-invasive acoustic and thermal detection to pinpoint the source — including slab leaks and underground lines — so we can open up only what we have to and repair it right the first time. Catching a leak early is one of the cheapest repairs you'll ever make; ignoring one is one of the most expensive.

A hidden leak rarely announces itself. By the time you notice a stain on the ceiling or feel a warm patch underfoot, water may have been moving through your walls, slab, or ceiling for weeks. In Southwest Florida that damage compounds fast: constant humidity feeds mold, and a slow leak inside a slab-on-grade home can rot subfloor and swell drywall long before anyone catches it.

Good Catch Plumbing locates leaks with electronic and acoustic equipment that pinpoints the source instead of guessing and cutting. We trace supply-line leaks, slab leaks, drain-line breaks, and the pinhole failures that plague copper pipe in our hard-water region. Then we repair what we find and confirm the fix is holding before we leave your home.

Signs You Have a Hidden Leak

Your water bill jumped without explanation

A sudden spike with no change in how you use water usually means water is escaping somewhere you can't see. It is often the first clue of a hidden supply-line or slab leak.

A warm or damp spot on the floor

In a slab home, a hot-water line leaking under the concrete can warm the tile or flooring above it. A patch that stays damp is another sign water is coming up from below.

Running water you can hear with everything off

If you hear a faint hiss or trickle when every faucet, toilet, and appliance is shut off, a pressurized line is likely leaking behind a wall or under the slab.

A musty smell, mildew, or mold

In our humidity, a hidden leak feeds mold quickly. A persistent musty odor or new mildew, especially inside a cabinet or along a baseboard, often points to moisture where it should not be.

Water pressure has dropped off

A leak on a supply line can rob pressure from your fixtures. If flow has fallen across the whole house, water may be escaping before it ever reaches the tap.

Ceiling stains or bubbling paint

Brown rings, sagging drywall, or paint that blisters usually mean water is tracking above or behind the surface, from a supply line, a drain, or plumbing near the roofline.

How Good Catch Finds and Fixes Hidden Leaks

Finding a hidden leak is detective work, and guessing wrong means unnecessary holes in your walls and floors. We start by confirming a leak actually exists and narrowing down where it lives, often with a pressure test to see whether your plumbing holds. From there we bring in the right tool for the job instead of cutting blindly.

How we locate the leak

  • Acoustic listening equipment that picks up the sound of water escaping a pressurized line, even under a concrete slab.
  • Thermal imaging that reveals the temperature difference where a hot-water line is leaking behind drywall or under flooring.
  • Moisture meters to map how far the water has already spread.
  • Video camera inspection to look inside drain and sewer lines for cracks, separated joints, or root intrusion.

Once we have the leak located, we walk you through what we found and your repair options before we open anything up. A pinhole leak on an accessible copper line may be a straightforward section replacement. A slab leak can often be handled by rerouting the affected line or accessing it through the concrete, and we lay out the honest trade-offs so you can decide.

Why Southwest Florida homes leak

Our water chemistry is tough on plumbing. Hard, mineral-heavy water works on copper from the inside while salt air corrodes fittings from the outside, which is why pinhole leaks are so common here. Slab-on-grade construction means many supply lines run through or beneath concrete, where a small leak can hide for a long time. Older neighborhoods still have cast-iron drain lines that crack and leak underground. And in snowbird and seasonal homes that sit empty for months, a slow leak can run all summer, driving up the bill and feeding mold before anyone walks back through the door.

Questions

Questions about Leak Detection & Repair

Can you find a leak without tearing up my walls or floors?
Yes, that is the whole point of electronic leak detection. We use acoustic listening gear, thermal imaging, and moisture meters to pinpoint the source first, so any opening we make is small and precise. Guesswork is what leads to unnecessary damage.
How do I know if I have a slab leak?
Common signs are a warm or damp spot on the floor, the sound of running water when every fixture is off, an unexplained jump in your water bill, or a drop in pressure. Because so many Southwest Florida homes are built on a concrete slab, supply lines running under it can leak out of sight. We confirm it with a pressure test and locate it before any concrete is touched.
My home sits empty in the off-season. How do I keep a leak from running for months?
This is one of the most expensive problems a seasonal home can have. Before you leave, consider shutting off the main water supply, and ask us about a whole-home leak sensor or an automatic shutoff valve that can catch a leak while you are away. We are glad to check the system over before you close the house up.
Why do the copper pipes in my house keep springing pinhole leaks?
Our hard, mineral-heavy water and salty coastal air are rough on copper, wearing it from the inside and the outside over time. Once one pinhole shows up, others often follow on the same run. We find the failures, repair or replace the affected sections, and talk honestly about whether repiping part of the line makes more sense than chasing leaks one at a time.
Do you repair the leak, or only locate it?
Both. We find the leak and, in most cases, repair it, whether it is a copper pinhole, a failed fitting, or a cracked drain line. Once the repair is done we retest to confirm it is holding. Many leaks are handled in a single visit, though larger slab or drain-line repairs can take longer.
