Why San Marco homes end up repiping
San Marco's housing dates largely to the 1920s and the decades after, which means original cast-iron drain lines inside the house and aging sewer laterals outside it — running under yards shaded by the mature oaks the neighborhood is known for. Those roots and those pipes drive most San Marco plumbing calls.
That combination is why a San Marco repipe conversation so often includes the sewer. The same era that gave you corroding cast-iron supply and drain pipe also gave you a clay or cast-iron lateral that oak roots have been working into for decades. Replacing interior pipe while ignoring a root-choked lateral just moves the next backup a few months out.
The smart San Marco move is a camera inspection of the lateral alongside the repipe evaluation. If the lateral is failing too, doing both together saves a second mobilization and a second round of yard and driveway work.
The pipe your San Marco home probably has
Homes built in the 1920s and the decades that followed almost always started with two materials now known to fail: cast-iron drain lines that corrode from the inside out, and galvanized steel supply lines that rust shut until pressure drops to a trickle. Homes touched in the 1978–1995 boom may also hide polybutylene, the gray plastic pipe insurers now flag.
- Cast iron (drains). Looks solid until it isn't — slow drains everywhere, sewer smells, and recurring backups a drain cleaning only fixes for a few months.
- Galvanized steel (supply). Rust builds up inside until flow fades and hot water runs brown; leaks start at the corroded threads.
- Polybutylene (supply, 1978–1995). Fails suddenly and can make a home hard to insure — replacing it is as much an insurance decision as a plumbing one.

What a repipe costs in San Marco
A whole-home repipe in San Marco runs $4,500–$15,000: PEX in a single-story two-bath home sits at the low end around $4,500–$8,000, larger or two-story homes run $7,500–$12,000, and copper pushes toward $9,000–$15,000. Most jobs take 2–5 days, and you stay in the house.
| Repipe project | Typical San Marco range |
|---|---|
| PEX repipe — single-story, 1–2 bath | $4,500–$8,000 |
| PEX repipe — larger or two-story, 3+ bath | $7,500–$12,000 |
| Copper repipe — whole home | $9,000–$15,000 |
| Polybutylene replacement (supply lines) | $4,500–$10,000 |
What moves the number: square footage and fixture count, one story vs two, pipe material, and how much drywall has to be opened and patched. For the full breakdown of materials, timeline and what's included, see our Jacksonville whole-home repiping guide. Every job through 904 Plumbers is quoted upfront, per project, before a wall is opened.
Copper or PEX for a San Marco home?
PEX is the right answer for most San Marco repipes: it costs 30–50% less than copper, doesn't corrode or pinhole in hard Jacksonville water, and installs faster with fewer joints. Copper still earns its place where pipe is exposed or an older home's owner simply prefers it.
Most licensed plumbers here run PEX for the hidden lines through attic and walls, and use copper only where it shows or where you want it. That mix keeps cost down without giving up the look where it matters.
Permits & what a repipe week looks like
A whole-home repipe takes 2–5 days and requires a City of Jacksonville plumbing permit, which the licensed plumber pulls. You live at home the whole time — water is off only a few hours at a stretch, on tie-over day.
The permit and inspection are your protection, not red tape — they confirm the new system was installed and pressure-tested to code. A licensed plumber pulls the permit and schedules the City of Jacksonville inspection as part of the job.
