Leak detection & repair

The expensive part of a leak is almost never the repair. It is the two weeks it ran before anyone noticed, and the wall somebody opened in the wrong place looking for it.

We find the fault first. That sounds obvious, and it is still the step most often skipped.

The signs, in the order they usually appear

A leak announces itself quietly. In rough order:

1. The meter moves with everything closed. Shut every faucet, stop the ice maker, and watch the meter for fifteen minutes. Any movement at all means water is going somewhere.
2. The bill changes before anything is visible. A jump with no change in how the property is used is worth investigating that week, not that quarter.
3. Smell before stain. A musty cabinet with no obvious damp is often the first physical sign.
4. Paint goes soft rather than marked. Press gently; a slightly spongy patch is water behind the finish.
5. A tile sounds hollow. Tap along a floor. A change in note means the bed underneath has moved.
6. Warm patches on a slab floor. That is a hot supply line leaking underneath.
7. The stain. By now it has been running a while, and the wet area is larger than the mark.

Where leaks actually happen in South Florida

Supply pipework. Copper develops pinholes, usually on horizontal runs and often where water sits. CPVC becomes brittle with age and UV exposure and fails at fittings. PEX is generally well-behaved and fails at crimps when they were not made properly.

Under the slab. Single-story properties across Kendall, Pinecrest and much of west Miami-Dade run supply under the concrete. A slab leak does not show on a ceiling; it shows as warm flooring, damp skirting, or a meter that never rests.

At fixtures. Angle stops, flexible connectors and the seal under a toilet account for a large share of what gets reported as “a leak in the wall”.

Behind tile. A failed shower valve or a perished waste seal wets the substrate long before it wets a room, which is why the first symptom is often in the room next door.

In older cast-iron waste. In Miami Beach, Coral Gables and the older parts of Coconut Grove, scaled and thinning cast iron seeps rather than bursts. It reads as a damp patch that comes and goes with use.

How we find it

We work from cheap and non-destructive toward expensive and invasive, and we stop as soon as we know.

• Isolate and observe. Closing sections of the system and watching the meter tells us which part of the property the loss is in.
• Listen. A pressurised leak makes a sound that carries along the pipe. On a slab that is often enough to place it within a small area.
• Read the moisture, not the mark. Damp travels along framing. Mapping where the water is wettest, rather than where it is visible, is what stops the wrong wall being opened.
• Pressure-test where it is warranted. Isolating and pressurising a section proves whether it holds, instead of inferring it.
• Then open up — once, in the right place. The smallest access that lets us do the repair properly.

The repair

What happens next depends entirely on what we found. A failed fitting is a fitting. A pinhole in an accessible copper run is a cut-out and a section replacement. A slab leak is usually either a spot repair where access allows, or a re-route above slab where it does not — and we will tell you which is honest for your property rather than which is easier for us.

Where a run has failed twice, we will say so plainly: a third patch on ageing pipework is money spent on the same problem, and repiping is the conversation to have.

Making good is part of the quote. Floors get protected, the opening gets closed, and the site is left clean. All work is completed to the Florida Building Code by a licensed Florida contractor, Lic. #CFC1433820.

What affects the cost

• How long it takes to find. An accessible fitting is minutes; a slab leak with no obvious symptom takes methodical work.
• Access. Under a vanity is one job. Behind tile, under a slab, or above a finished ceiling is another.
• Pipe material and condition. A sound run with one fault repairs cheaply. Pipework that is failing generally does not.
• Making good. Matching a tile you no longer have costs more than closing plain drywall.
• Building requirements. Insurance certificates, notice periods and booked service elevators all take time.

No prices without seeing the job. You get the figure in writing first.
