Slab leak repair and replacement in Miami
Miami-Dade is a county of slab-on-grade construction. Houses from the 1950s through the 1980s are commonly poured slabs with copper supply lines, and newer builds use PEX. Limestone and sand lie close to the surface, and the water table is high, so water from a leak can disappear into the ground for a long time before anything shows.
Homeowners in Miami often search for a foundation leak when the problem is an under-slab leak in a water line. The two are related: water escaping under the slab can soften the soil the foundation rests on.
Professional leak detection in Miami uses pressure tests, acoustic listening and thermal imaging to find the leak before any concrete is opened.
Condos are a large part of the housing stock, from older mid-rise buildings to newer towers, and many ground-floor units sit directly on a slab. Pools are common in single-family areas. Those three facts, building age, shared construction and pools, shape most of the leak calls we are asked about here.
The Miami pages below are organized by part of the county. Each lists its ZIP codes and describes the housing, the likely pipe types and what tends to hide a leak in that area.
A visit in Miami-Dade usually begins on the phone. We ask what you noticed, whether the home is a house, townhouse or condo, what year it was built, whether the meter moves with everything off and whether there is a pool or irrigation. The answers tell the technician what to bring and whether building access needs to be arranged.
On arrival the technician reads the meter, isolates the lines and tests them, then listens across the floor and marks the likely position. The findings are explained in plain terms with the options and the price before any work begins. If the floor is to be opened, the opening is kept as small as the location allows.
If you are not sure what you are seeing, call anyway. A short conversation is often enough to tell whether it is worth a visit, and the technician will say so if it is not.
A short history of Miami
Miami was incorporated on July 28, 1896 and the seat of Miami-Dade County since 1844. Miami was settled after 1858 and founded by Julia Tuttle.
The Tequesta lived in the area for about 2,000 years, with a village at the mouth of the Miami River dating to 500 to 600 BCE. The U.S. built Fort Dallas on the Miami River in 1836 during the Second Seminole War. Julia Tuttle, a local citrus grower, owned the land where the city was built, and Miami was incorporated in 1896. The city is named for the Miami River, which comes from Mayaimi, the historic name of Lake Okeechobee.
Homes in Miami were built across many decades, so a technician asks about the age of the house and its pipe material before choosing a test.
The setting of Miami, Miami-Dade County
Miami sits on a broad plain between the Everglades to the west and Biscayne Bay to the east. The Biscayne Aquifer lies beneath the plain, which is why there is no subway. The highest natural point in the city is in Coconut Grove on the Miami Rock Ridge at about 24 feet above sea level. The 5.5-mile Miami River runs from the Miami Canal near Miami International Airport to Biscayne Bay.
In Miami, outdoor water such as sprinklers and rain can look like a leak under the house, so a technician tests the lines first.

Away for the season?
In Miami, many homes here stand empty for part of the year, and a slab leak does not need anyone present to keep running. A short routine on the way out and on the way back is a simple safeguard. See before you leave leak checklist and seasonal home slab leaks.
Read the meter. With everything off, write down the reading and the date before you leave.
Close the main. Or leave it on and ask someone to check the dial at intervals.
Give someone a number. A neighbor or manager who can reach you and us.
On return, check before you unpack. Feel the floors, then open the main, close every tap and watch the meter.
Call if it moves. A moving dial in an empty or newly opened home is the reason to call.
The five-minute meter check
In Miami, the meter check is the one safe test a homeowner can do, and it tells a technician a good deal before they arrive.
Turn everything off. Close every tap and stop the washer, dishwasher and irrigation.
Find the meter. It is usually near the street or the front of the property. Lift the lid carefully.
Watch the dial. The small triangle or wheel spins at the slightest flow. The main dial should be still.
Wait an hour. Read the meter, wait with everything still off and read it again.
Call with what you saw. Share both readings, the time and any warm or damp areas. See water meter leak check.
We explain the choices for your floor.

Urban Core and Bayfront. The urban core and the bayfront neighborhoods around it are dominated by mid-rise and high-rise residential buildings, with older low-rise apartments and bungalows between them. Many buildings stand on slabs or on podiums above parking, so what lies under a given unit depends on the floor it is on.
West Miami and Flagami. West of the core, the housing is mainly single-story concrete block homes on slabs, many built from the 1950s into the 1970s, with smaller lots and a mix of original and updated plumbing. Copper supply lines under these slabs are common, and some have been replaced or rerouted over the years.
North Dade Corridor. Across the northern part of the county, single-family blocks from the 1950s to the 1970s sit beside newer townhouse and condo communities nearer the coast. Slabs and copper supply lines are the norm in the older blocks.
Kendall and Pinecrest. South of the core, the housing runs from large lots with homes from the 1950s and 1960s to the dense subdivisions of the 1970s and 1980s. Most are slab construction. Copper supply lines are typical of the older houses, and some mid-era subdivisions may have other pipe types.
South Dade and Cutler Bay. Further south, neighborhoods are a mix of 1980s and 1990s tract homes, newer subdivisions and agricultural-edge properties. Slab construction is almost universal, and the era of building means copper in some homes and PEX in newer ones.
Southwest Dade. In the southwest and west of the county, much of the housing was built from the 1980s onward, on slabs, with a high share of newer subdivisions. PEX supply lines are common in the more recent homes and copper in the earlier ones.
