It usually does. Fort Lauderdale’s close-in neighborhoods like Rio Vista and Colee Hammock were built up mostly in the 1920s and 1930s, and homes from that era commonly carry original cast iron waste lines and, on the supply side, galvanized steel that was never meant to last a century. A repair on a house like that starts with figuring out what pipe material is actually in the walls, not assuming it matches a newer build.
The city’s canal-front neighborhoods add a second wrinkle. Las Olas Isles was dredged in the 1920s and Coral Ridge developed from the early 1950s, and both put copper and cast iron within reach of salt air and dock spray for decades, which shows up as corrosion at fittings and outdoor bibs earlier than it would inland. Any repair that touches a seawall or dock along those canals typically needs added review beyond a standard plumbing permit, which we build into the timeline before work starts.
