Naples’s Trusted Leak Detection Pros
A water bill that doubled. The sound of running water when everything’s off. A warm patch on the marble. If something’s leaking in your Naples home and you can’t see where, McGrath Plumbing finds it with non-invasive electronic leak detection — no exploratory holes, no torn-up finishes on a guess.
Nowhere does precise leak location matter more than in Naples. Between the marble, stone, and hardwood in the estates of Port Royal and Aqualane Shores and the irreplaceable finishes in historic Old Naples homes, hunting for a leak the wrong way can turn a plumbing repair into a six-figure remodel. We pinpoint it to inches first, then fix it — cleanly.
Leak Detection Services We Provide in Naples
Electronic Leak Detection
Acoustic listening and line tracing pinpoint hidden leaks under slabs, behind walls, and underground — located to inches, not rooms, before anything is opened.
Slab Leak Location
A pressurized line leaking under the slab — common in Naples’ older copper-plumbed homes. We confirm, map, and locate it precisely to protect the flooring above.
Irrigation, Pool & Estate Lines
Naples estates run extensive irrigation, pool, water-feature, and landscape plumbing. We trace mystery water loss across the whole property, not just the house.
Repair After Detection
We don’t just hand you a report and leave — same company, same visit where possible: find it, show you, fix it, protect the finishes.
Why Leak Detection Matters More in Naples
Luxury finishes make the wrong approach catastrophic. A slab leak under imported marble in Port Royal, or behind the custom millwork of an Aqualane Shores estate, is not a place to go hunting with a jackhammer. Electronic detection lets us mark the leak within inches so any repair is one small, precise opening — protecting finishes that cost a fortune and often can’t be matched. In Naples this isn’t a luxury; it’s the only sensible way to work.
Historic Old Naples homes hide leaks in old pipe. The mid-century homes of the historic district run aging galvanized and copper that develops pinhole leaks after decades in our aggressive water. In a home where the character IS the value, precise location and careful repair matter as much as the fix itself. We treat historic homes accordingly.
Estates mean long runs and hidden water loss. Naples’ large waterfront lots carry extensive irrigation, pool, fountain, and landscape plumbing — a lot of buried pipe where a leak runs unseen for weeks. When a bill spikes and the house checks out, the leak is often out in the grounds. We trace the entire system, not just the fixtures.
The heaviest seasonal population raises the stakes. A pinhole in an occupied home gets caught in days; the same leak in a closed-up Naples estate runs from May to November — and in Florida humidity that’s mold remediation in a multimillion-dollar home before it’s a plumbing bill. We do pre-departure pressure checks for seasonal owners who’d rather leave with certainty.
How Do You Find a Leak Without Tearing Up My Home?
Acoustic equipment listens for the signature of pressurized water escaping a pipe; line locators map exactly where your plumbing runs; pressure testing isolates which line is losing water. Together they let us mark a leak within inches — so if a repair does need an opening, it’s one small precise spot instead of a hunt through marble, millwork, and hardwood.
Detection is quoted upfront, the $68 service call applies toward the work, and you’ll see the evidence yourself before any repair decision — we show you, not just tell you.

Naples Leak Detection FAQs
Can you find a leak without damaging my marble or hardwood floors?
Yes — that’s the entire point of electronic detection, and it’s exactly why Naples homeowners with high-end finishes call us first. We locate the leak to within inches before anything is opened, so repairs are surgical, not destructive.
What are the signs of a slab leak in my Naples home?
Warm spots on the floor, running-water sounds when everything’s off, a water heater that never rests, cracked tile or stone, damp baseboards, or an unexplained bill jump. Any one of these in an older Naples home is worth a check.
My water bill doubled but I can’t find a leak. What now?
On a Naples estate it’s often out in the irrigation, pool, or fountain plumbing, not the house. We check for running toilets first, then pressure-test and trace the full property to find where the water’s going.
I’m seasonal — can you check for leaks while my home is closed up?
Yes — we do pre-departure pressure tests and can coordinate with your property manager or estate manager. A silent leak in an empty Naples home is the most expensive kind, both to your bill and your finishes.
Do you work on historic Old Naples homes?
Yes, and we treat them with the care they deserve — precise location and careful repair that respects original materials, because in a historic home the character is the value.
How much does leak detection cost in Naples?
It’s quoted as a flat visit upfront, and the $68 service call applies toward it. If we repair the leak, detection and repair are quoted together before work starts — no surprises.
