Marco Island’s Trusted Leak Detection Pros
A water bill that doubled. The sound of running water when everything’s off. A warm patch on the tile. If something’s leaking in your Marco Island home or condo 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.
On Marco, precise leak location matters twice over: the island’s high-end finishes make demolition costly, and in a condo, a hidden leak can quietly damage the units around yours. We pinpoint it to inches first, show you exactly what we found, then fix it — protecting your home and your neighbors.
Leak Detection Services We Provide on Marco Island
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 Marco’s older copper-plumbed homes. We confirm, map, and locate it precisely to protect the finishes above.
Condo & Multi-Unit Leaks
In Marco’s towers, a leak can travel between units. We locate the source precisely and coordinate with associations and neighbors so the right unit gets the right repair.
Seawall, Pool & Irrigation Lines
Marco’s waterfront homes run pool, dock, seawall, and irrigation plumbing. We trace mystery water loss across the whole property, not just the house.
Why Leak Detection Matters More on Marco Island
Salt drives pinhole leaks faster here. Marco’s barrier-island salt air corrodes copper supply lines from the outside while our aggressive water attacks from within — so pinhole leaks develop sooner on the island than inland. Warm floor spots, running-water sounds, or a water heater that never rests are the classic tells, and we locate the leak precisely before touching a finish.
Condo leaks are everyone’s problem. In Marco’s mid-rise and high-rise buildings, a hidden leak doesn’t stay in your unit — it travels through floors and shared walls to the neighbors below. Precise electronic location lets us find the true source fast, coordinate with the association, and get the correct unit repaired instead of guessing and opening walls in the wrong home.
Luxury finishes make the wrong approach costly. Marco’s waterfront homes carry marble, stone, and custom finishes, and hunting for a leak with a jackhammer can turn a repair into a remodel. Electronic detection marks the leak within inches so any opening is small and precise, protecting finishes that are expensive — and often impossible — to match.
Waterfront plumbing hides leaks outdoors. Marco’s canal and Gulf-front homes run extensive pool, dock, seawall, and irrigation plumbing — a lot of buried and exposed pipe in a salt environment. When a bill spikes and the house checks out, the leak is often out at the pool or seawall. We trace the whole property.
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, whether in a slab home or a condo shared wall.
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.

Marco Island Leak Detection FAQs
My downstairs neighbor’s ceiling is wet — is it my unit?
Maybe, maybe not — water travels in condo buildings, and the leak’s source isn’t always the unit above the damage. Electronic detection finds the true source precisely, so the right unit gets repaired and the association has clear answers. We do this coordination routinely on Marco.
What are the signs of a slab leak in my Marco home?
Warm spots on the floor, running-water sounds when everything’s off, a water heater that never rests, cracked tile, damp baseboards, or an unexplained bill jump. Salt speeds pinhole leaks on the island, so any of these is worth a prompt check.
Can you find a leak without breaking my expensive floors?
Yes — that’s the entire point of electronic detection, and it’s why Marco 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.
My water bill doubled but I can’t find a leak. What now?
On a Marco waterfront home it’s often out in the pool, seawall, or irrigation 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 condo is closed up?
Yes — we do pre-departure pressure tests and can coordinate with your property manager or association. A silent leak in an empty Marco condo can damage neighbors as well as your own unit.
How much does leak detection cost on Marco Island?
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.
