Cape Coral’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 Cape Coral home and you can’t see where, McGrath Plumbing finds it with non-invasive electronic leak detection — no exploratory holes, no torn-up floors on a guess.
We pinpoint the leak with acoustic and line-tracing equipment, show you exactly what we found, and give you a firm plan to fix it. On Cape Coral’s slab homes with long irrigation and pool runs, locating a leak precisely — instead of demolishing to hunt for it — is the difference between a tidy repair and a remodel.
Leak Detection Services We Provide in Cape Coral
Electronic Leak Detection
Acoustic listening and line tracing pinpoint hidden leaks under slabs, behind walls, and underground — located to inches, not rooms.
Slab Leak Location
A pressurized line leaking under the concrete slab — common in Cape Coral’s older copper-plumbed homes. We confirm, map, and locate it precisely before anyone opens a floor. See our Cape Coral slab repair page.
Irrigation & Pool Line Leaks
Cape Coral lots run extensive irrigation and pool plumbing, and canal-side homes add seawall and dock lines. 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.
Why Leak Detection Matters in Cape Coral
Slab leaks in the copper-plumbed homes. A large share of Cape Coral was built on slabs with copper supply lines run underneath, and after decades in contact with our aggressive water, pinhole leaks under the slab are common — usually on the hot side first. Warm floor spots, running-water sounds, or a water heater that never rests are the classic tells in the older canal neighborhoods. We locate them precisely so any repair is surgical.
Big lots, long runs, hidden water loss. Cape Coral homes sit on generous lots with extensive irrigation and, for many, pools and canal-side 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 irrigation, pool supply, or a seawall line. We trace the whole system.
Well-water homes hide leaks differently. On a private well in the north Cape, a leak doesn’t show up on a city meter the same way — so it can run a long time before anyone notices, driving the pump to cycle constantly and running up electric instead of water bills. A pump that won’t stop kicking on is often the first clue of a hidden leak on a well system.
Seasonal homes raise the stakes. A pinhole in an occupied house gets caught in days; the same leak in a closed-up seasonal home runs May to November — and in Florida humidity that’s a mold remediation before it’s a plumbing bill. We do pre-departure pressure checks for owners who’d rather leave with certainty.
How Do You Find a Leak Without Tearing Up My House?
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 your floors and walls.
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.

Cape Coral Leak Detection FAQs
What are the signs of a slab leak in my Cape Coral 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. Any one of these in an older slab-built Cape home is worth a check.
Can you find a leak without breaking my floors?
Yes — that’s the entire point of electronic detection. 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?
In Cape Coral it’s often out in the irrigation, pool supply, or a seawall line, not the house. We check for running toilets first, then pressure-test and trace the full system to find where the water’s going.
I’m on a well and my pump keeps running. Is that a leak?
Often, yes — on a well, a hidden leak makes the pump cycle constantly since there’s no city meter to flag the loss. A pump that won’t rest is a classic sign of a leak somewhere in the system, and we can trace it.
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 if something needs attention while you’re away. A silent leak in an empty Cape home is the most expensive kind.
How much does leak detection cost in Cape Coral?
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.
