A third of homes from the 1950s
About 34 percent of South Miami's homes were built in the 1950s, and roughly two in three predate 1980, by 2024 Census estimates.
Miami-Dade County
A third of South Miami's homes went up in the 1950s, and the low ground by the canals floods first. Call, and the wet rooms get found and dried.

South Miami is a 2.3-square-mile city between Coral Gables and Pinecrest, built up around the old Larkins settlement at Sunset Drive and Red Road, and it became a city in 1927. Most of the water damage here comes from inside an older house, when a pipe or fitting finally gives out. In the rainy months it also comes up from the low streets near the canals, or back up through a septic tank that can’t drain. If you meant the communities down past Cutler Bay, such as South Miami Heights and Goulds, that’s our South Miami-Dade page.
About a third of the homes in town date from the 1950s, more than double the county’s share, and roughly half of all homes are detached houses. Most of the rest are in apartment and condo buildings of 20 or more units.
A house that age has had 70 years of patches, additions and replumbing, and the leak that soaks a room is often a fitting nobody has looked at since the last remodel. A supply line under the kitchen sink, the valve behind the washer or a water heater tucked in a utility room can run for hours before anyone notices. On a slab-on-grade house the water spreads across the floor and wicks up into the baseboards and the bottom of the drywall.
Readings decide what stays. Drywall that soaked for a day or two can often be dried in place with air movers and dehumidifiers. Drywall that sat wet longer, or swelled and crumbled at the base, gets cut out above the wet line. The guide on cutting or drying wet drywall walks through how that call is made, and water damage restoration covers the full job from shutoff to dry walls.
The city’s own stormwater study describes South Miami as higher along its east and west edges, with a low valley running beside a chain of small canals: the Broad, the Ludlam Glades and the Twin Lakes. They empty into the Snapper Creek Canal, which also takes runoff from the built-up neighborhoods west of town. The study notes that the low ground along them falls in FEMA flood zone AE.
In a long storm, Snapper Creek is draining a much bigger area than South Miami. The city’s flood notices warn that heavy, prolonged rain can overwhelm the drainage system, canals included. It gets worse after a run of wet days, once the ground is saturated and the water table is up, and on land this flat the water can show up almost anywhere.
When street or yard water gets inside, the job is flood cleanup, not a regular dry-out. Furniture legs, cabinet bases and door casings take on dirty water too. Floodwater and leak water explains why the two get handled differently.
The city told the Florida Senate in 2026 that more than 2,000 residents still depend on septic systems it described as outdated and malfunctioning. A section the city calls Sub-area K went first because of its exposure to sea-level rise: 46 homes and a park building in the first phase, with 159 more homes planned in the second.
Until a street is connected, a tank in saturated ground has nowhere to send the water. The first sign is usually a gurgling toilet or a shower drain that fills from below. Anything soft the backup touched is treated as sewage and removed, and the floors and walls are disinfected before drying. Sewage cleanup covers that work, and the steps to take in the first hour are in what to do when sewage backs up.
June through October brings the heaviest rain, and it’s also when the AC runs hardest. A drip that gets ignored for a few weeks in August can grow mold on the back of the drywall before the paint shows a thing. The first sign is usually a smell in one closet or bedroom.
Testing and moisture mapping find how far it spread. Mold remediation seals off the affected room, removes the moldy material and dries what’s left so it doesn’t come back. There’s more on the timing in mold after water damage.

When you call, say whether the water came from a pipe, from the yard or up through a drain, and whether the house is on septic. A rough build year helps too.

The city's stormwater master plan describes a low valley beside the Broad, Ludlam Glades and Twin Lakes canals, which drain to the Snapper Creek Canal, and puts those low areas in FEMA flood zone AE.
More than 2,000 South Miami residents still rely on septic systems, the city told the Florida Senate in a 2026 funding request, and homes are being moved to sewer in phases.
The city warns that heavy, prolonged rain from June through October can exceed the drainage system and its canals, and that on such flat ground flooding can happen almost anywhere in town.

FAQ
No. South Miami is the small city between Coral Gables and Pinecrest, around Sunset Drive and Red Road, in ZIP 33143. South Miami-Dade means the unincorporated communities much farther south, such as South Miami Heights and Goulds. Both are covered.
Yes. ZIP 33143 is covered across South Miami and the parts of Coral Gables that share it.
The baseboards on the outside walls, the cabinet floors under the sinks, the AC closet and the drywall around windows. Moisture meters and a thermal camera show where water is sitting behind a wall, so only that section gets opened. Any mold found behind it is removed before the wall is closed back up.
No. Water that crossed the yard first is treated as floodwater, because it brings in soil and whatever was on the ground. Wet carpet and pad come out, the lower drywall is cut away and the floor gets cleaned before any drying starts.
