Failing cast-iron drain lines from the 1950s and 1960s get replaced with modern PVC, either by trenching the line’s path or, where the site allows it, from existing access points.
How do you know a cast-iron line needs full replacement instead of a repair?
Cast iron corrodes from the inside, so a pipe that still looks solid on the outside can have lost most of its wall thickness underneath. A camera run through the line shows scaling, flaking, and a rough, narrowed interior, the signs that the pipe is failing structurally rather than simply clogging in one spot.
A single collapsed or cracked section can sometimes be cut out and rejoined without touching the rest of the line. Once several sections show the same corrosion pattern, though, patching one area only delays the next failure a few feet further down, which is usually when full replacement becomes the more practical choice.
The camera footage is the deciding factor either way, not a guess based on the home’s age or how long a section has been clogging. That footage is what actually decides which section of pipe comes out, rather than an estimate of the whole line’s age.
Signs worth a call
Corrosion inside the pipe shows up in a few consistent ways before it shows up as a full backup.
Water that runs orange or brown after the first minute, especially from a fixture served by an older section of line.
A drain that clears with a cable but slows again within a few weeks, unlike a one-time object clog.
Ground or flooring above a cast-iron line that never fully dries out, even without recent rain.
A faint but persistent odor near a floor drain or cleanout, often from a hairline crack rather than a full break.
Multiple fixtures on the same branch line losing pressure together, rather than a single fixture clogging on its own.
Working in this area
A few facts about this city’s housing stock explain how much cast iron is still in the ground.
Housing built through the 1950s and into the 1960s on the east side of the city ran almost exclusively on cast-iron drain lines, and many of those original lines are still in the ground today, at or past their expected service life.
A beachfront tower built more recently can still tie into an older shared stack at the point where it connects to the municipal system, so a building’s full plumbing history sometimes matters as much as a single unit’s own age.
Replacing a section of drain line, whether by trenching or a trenchless method, is permitted work in Broward County, and that step is handled as part of the job rather than an optional add-on.

Encountering severe root intrusion in our main sewer line meant the entire pipe needed to be aggressively cleared and chemically treated. Applying a specialized foaming root killer guarantees the aggressive tree tendrils won't immediately…

Before you call
Homes built before the 1970s in this area often do. A camera run through a cleanout confirms it either way, along with the pipe’s actual condition.
Not always. A trenchless liner can replace a section from existing access points on many jobs; whether it applies depends on what the camera shows.
Sometimes, if the rest of the line is still sound. That is exactly what the camera inspection is for, deciding section by section.
It depends on the length and access involved; the plumber gives a real estimate for your specific line after seeing the footage.
Structural line work in Broward County goes through the standard permitting process, and that is handled as part of the job.
