Slab leak repair and replacement in Key Biscayne: what it looks like first
A leak under a concrete floor rarely announces itself in Key Biscayne. The clues are indirect: the meter, the bill, a floor that feels different and sometimes a sound in a quiet room. Concrete is only opened once tests have shown where the water is going.
People describe the same problem in different ways: a slab leak, an under-slab leak, a foundation leak or a water leak under the house. In Key Biscayne homes built on concrete, they usually mean a supply or drain line leaking below the floor.
The goal of leak detection is a marked spot on the floor and a clear answer about which line is leaking, so Key Biscayne homeowners can compare repair options with real information.
The Atlantic side of South Florida is flat and low, with limestone and sand close to the surface and groundwater not far below. A damp slab here can come from the ground as easily as from a pipe, so testing comes first.
Key Biscayne history and what it means for older plumbing
Key Biscayne is a village in Miami-Dade County. The Cape Florida Lighthouse was built in 1825.
The first known inhabitants were the Tequesta. The Rickenbacker Causeway was originally built in 1947 to connect the island to the mainland. Bill Baggs Cape Florida State Park opened on January 1, 1967.
Homes in Key Biscayne were built across many decades, so a technician asks about the age of the house and its pipe material before choosing a test.

Key Biscayne is a barrier island about 5 miles long and 1.5 miles wide between the Atlantic Ocean and Biscayne Bay. Key Biscayne is the southernmost of the barrier islands on Florida's Atlantic coast, south of Miami Beach. Average elevation is under 5 feet above sea level.
In Key Biscayne, outdoor water such as sprinklers and rain can look like a leak under the house, so a technician tests the lines first.

Pipes and homes in Key Biscayne
Homes in Key Biscayne vary in age, and age is the first clue to the plumbing. The area has many condos, rentals and older slab homes, so access, shared lines and who to notify often matter as much as the repair. See condo ground floor slab leaks.
Housing and pipes in Key Biscayne
Homes in Key Biscayne built from the 1960s through the 1990s commonly have copper supply lines in or beneath the slab. Copper wears over decades, and pinhole leaks are the usual form.
Pools and irrigated lawns are common in this part of Miami-Dade County. Both draw on the house supply and both can show on the meter like a leak, so the technician rules them out first. The technicians we connect you with do not repair pools or irrigation.
Key Biscayne became a village in 1991, and it spans roughly 1.2 square miles of Miami-Dade County. What lies under a given slab depends on the year the house went up, not on the age of the village.
How leak detection works in Key Biscayne
In Key Biscayne, the technician starts with your account of the problem and the home's age, reads the meter with the water off and tests the lines one at a time. Pinpointing comes last, followed by a plain explanation of repair choices and cost.
What to check first in Key Biscayne
If you suspect a leak in Key Biscayne, start with these five steps and write down what you see.
Make the house quiet. No showers, no laundry, no sprinkler cycle. A still house is what lets the meter tell the truth.
Use your hands and ears. A floor that feels warm, flooring that has lifted or softened and a quiet running sound are the usual clues. Mention it when you call about your Key Biscayne home.
Read the meter twice. Write down the reading, wait fifteen minutes with no water in use, then read it again. A changed number at your Key Biscayne property is worth a call. See the water meter leak check.
Look back at the bills. Two or three months of rising charges with no new pool, guests or watering is worth pointing out. This applies to your Key Biscayne home too.
Call with your notes. Tell the person on the line what the meter did, which rooms are affected and how long it has been going on. That is all a Key Biscayne dispatcher needs to start.
