Repiping vs Spot Repair: When Does a House Actually Need Repiping?

The second leak is the one that should make you stop and think. The first one is bad luck. The second one, in a different room, eighteen months later, is your plumbing telling you something about itself — and that’s the point where whole house repiping stops being an overreaction and starts being the cheaper option.

The short version: repipe when the pipe material is failing, repair when a single identifiable event caused a single leak. A nail through a line during a bathroom remodel is a repair. A house that has leaked three times in two years, in three different places, with no common cause, is a house whose pipes have reached the end of their service life. Patching that is throwing good money after bad.

We’ve been opening up walls in Canton, Woodstock, Holly Springs, and across Cherokee County for 25+ years, and the houses fall into fairly predictable groups. Here’s how to figure out which one yours is in.

Start With What Your Pipes Are Made Of

Material is the single biggest factor, and it’s usually the fastest thing to check. Look under a sink, in the crawl space, or at the water heater connections. If you’re not sure what you’re looking at, our guide to identifying the pipe types in your house walks through the visual tells.

Supply pipe material	Common in	Repair or repipe?
Polybutylene (flat gray, crimped rings)	Homes built 1978–1995	Plan a repipe. It fails from the inside out — repairs don’t stop it
Galvanized steel (dull gray, threaded)	Pre-1960s homes and farmhouses	Repipe when leaks start. Corrosion is system-wide by then
Copper, isolated pinhole	Any age	Repair — unless pinholes are appearing in multiple runs
Copper, repeat pinholes	Homes 40+ years old, aggressive water	Repipe the affected system
PEX or CPVC	Homes built roughly 1995 onward	Repair. Failures are almost always a fitting, not the pipe

Polybutylene is the one that matters most around here. A lot of Cherokee County’s late-’70s through mid-’90s subdivisions were plumbed with it, and it degrades from chlorine exposure on the inside of the pipe where you can’t see it. The house looks fine right up until it doesn’t. The class-action settlement that once helped homeowners pay for replacement closed years ago, so the cost sits with the owner now — and many insurers won’t write or renew a policy on a house that still has it. If you have polybutylene, you’re not deciding whether to repipe. You’re deciding when.

The Leak-Count Test

Material tells you the risk. Leak history tells you where you are on the curve.

• One leak, clear cause, in ten years. Repair it. Nothing is wrong with your plumbing.
• Two leaks in five years, different locations. Watch it. Ask your plumber to note pipe condition every time a wall is open.
• Three or more leaks in two years, no common cause. Repipe. You are now paying repair prices on a schedule, and the water damage is the part that actually costs money.

That last line is the one homeowners underestimate. A targeted line or leak repair runs $600–$2,500 depending on access and what has to come apart. That’s manageable once. It’s not manageable every eight months, and it doesn’t account for drywall, flooring, insulation, and the mold remediation that follows a leak nobody found for a week.

Symptoms That Point at the Pipes, Not the Fixture

Some problems look like a fixture issue but are really the whole supply system talking:

• Rusty or brown water from multiple taps. Sediment from corroding galvanized pipe. If it’s only one tap, or only on the hot side, the cause is narrower than the whole system.
• Pressure that’s dropped everywhere over the years. Galvanized pipe closes up from the inside as scale builds. New fixtures won’t fix a 3/4” line that’s effectively 3/8” now.
• Visible green crust or white mineral bloom at joints. Slow weeping that hasn’t broken through yet.
• Water that’s warm at the tap when it should be cold. Often means supply lines running unprotected through a hot attic — a repipe is the chance to reroute them.
• A water bill that climbs with no change in usage. That’s a leak somewhere you can’t see. Before you assume the worst, professional leak detection in Canton finds it without guessing which wall to open.

One thing worth separating out: a leak in the buried line between the meter and the house is not a repipe question. That’s a service line issue, and replacement of a water or sewer line runs $5,000–$15,000+ on its own. If the trouble is outside the foundation, the fix is outside the foundation.

Who does whole house repiping in Canton, GA?

Precision Plumbing & Septic does whole house repiping in Canton, Woodstock, Holly Springs, Ball Ground, and throughout Cherokee County, as a licensed Georgia Master Plumber operation with 25+ years on North Georgia homes. A repipe is a scoped job, not an estimate over the phone: we walk the house, confirm the pipe material and where the runs go, count fixtures and stories, check crawl space or slab access, and price the whole thing in writing before anything is opened up. There’s no standard repipe number we can quote you honestly — a single-story ranch on a crawl space and a two-story slab home with three bathrooms are completely different jobs — so we quote yours, not an average.

Most residential repipes we run take two to four working days. Water is off during working hours and back on each night in nearly every case. Modern PEX means far less demolition than the copper repipes of twenty years ago: we work through access holes and a limited number of drywall cuts rather than opening entire walls.

When Spot Repair Is Genuinely the Right Call

We say this a lot, and we mean it: most leaks are just leaks.

• A frozen burst in an exterior wall or crawl space. Common in North Georgia because our pipes aren’t buried deep or insulated for cold that only shows up a few nights a year. Fix the pipe, insulate the run, move on.
• A nail or screw through a line. Someone hung a shelf. It’s a repair.
• A failed fitting on otherwise good PEX or CPVC. Fittings fail; the pipe is fine.
• A single copper pinhole in a house with no other history. Repair it and note the date.
• You’re selling within a year or two. A disclosed, documented repair is often the better financial move than a repipe you won’t be there to use — though polybutylene will come up in the buyer’s inspection either way.

What a Repipe Actually Buys You

Beyond ending the leak cycle, a repipe resets a few things at once: pipe runs get rerouted out of hot attics and unheated crawl spaces, undersized lines get corrected so pressure comes back, and every shutoff valve in the house gets replaced with one that actually turns. If you’ve been living with low water pressure across the whole house, a repipe on old galvanized often solves it outright — nothing else will.

It’s also the moment to fix decisions the original builder made badly. Insulation on lines through exterior walls, a manifold layout that lets you isolate one bathroom instead of the whole house, and hose bibs that don’t freeze are all cheap while the walls are open and expensive later.

FAQ

How long does whole house repiping take?

For most Cherokee County homes, two to four working days. Water is shut off during working hours and restored each evening in nearly every job. Larger homes and slab foundations take longer than crawl-space homes because access is harder.

Do I have to move out during a repipe?

Almost never. Water is on overnight, and the work is contained to access points rather than gutted walls. Families stay in the house for the great majority of the repipes we do.

Does homeowners insurance cover repiping?

Generally no. Insurance covers sudden damage caused by a leak — the drywall, flooring, and contents — not the replacement of pipes that wore out. That’s exactly why polybutylene is such a problem: some carriers decline or non-renew coverage on houses that still have it, which means the repipe is out of pocket and the leak damage may not be covered either.

Can I repipe just one bathroom or one section?

Sometimes, and it can be a reasonable middle path if a single branch serves the trouble spot. But when the failing material runs through the whole house, a partial repipe just relocates the next leak. We’ll tell you straight which one your house is — choosing a plumber who gives you that answer matters more on this job than on almost any other.

How do I know if I have lead pipes?

Lead supply piping is rare in Cherokee County homes but worth ruling out in anything pre-1950. The EPA’s Protect Your Tap walks you through identifying your service line at home, and their overview of lead in drinking water explains where it comes from. If you find lead, replacement isn’t a maintenance decision — it’s a health one.
