When the pipes themselves are the problem — not one leak, but the material — here's how to know, and what replacing them involves.
Jackson County's housing splits by era, and so does its pipe. In the oldest stock — Moss Point, where a quarter of homes predate 1960, and the pre-war and shipyard-era streets of Pascagoula and Escatawpa — original galvanized steel supply lines are the classic suspect. Galvanized corrodes from the inside for decades: pressure fades room by room, water runs rusty after a vacation, and threads crumble when anyone tries a simple repair. That's a material at the end of its life, and repairs on it are rented time.
The second story belongs to the newer half of the county. Roughly a quarter of Jackson County's homes went up between 1980 and 1999 — squarely overlapping the years when polybutylene supply pipe was widely installed in American houses before its failures made it notorious. Construction dates don't prove what's in any one wall, so this isn't a claim about your house; it's a reason to look. The pipe is usually gray, stamped "PB", and visible at the water heater connections or under sinks. If that's what you find, a professional assessment is worth scheduling before the pipe schedules it for you.
Less drama than the word suggests. New supply lines — typically PEX, sometimes copper — are run through attic and walls to every fixture, with access openings cut where needed and patched after. Most single-family repipes run a few days of work, the water is only off for portions of it, and the job is quoted from your home's fixture count and layout rather than off a chart. It is real money — and it's also the repair that ends the leak-of-the-season pattern instead of renewing it.
Leaks arriving in series rather than singly. Pressure that's faded over years, worst at the far fixtures. Rust-tinted water from the hot side. Fittings that fail during unrelated repairs. Any one of these is a data point; two or three together are the pattern — and the free quote is a cheap way to learn whether your pipe has years left or is already campaigning for retirement.
It's quoted per house — fixture count, stories, attic versus slab routing, and finish repairs drive it — so honest operators don't price it from a chart. Expect a four-to-five-figure conversation, and expect the quote to be free and itemized enough to compare.
PEX dominates repipes now: it's flexible enough to fish through finished walls with fewer openings, it tolerates minor freezes better, and it costs less installed. Copper remains a fine material with a longer track record. A professional will give you the case for each in your specific house.
Sometimes — hot side first, or the worst runs first — but staging adds mobilization cost and leaves old pipe in service longer. Price the staged and all-at-once versions side by side before deciding; the difference is often smaller than expected.
