Repiping a home is a big job, and the quotes you get can vary widely. In the Upstate, a whole-home PEX repipe runs $3,700 to $7,350, while copper costs roughly double. This guide explains what separates the two materials, when a home actually needs a full repipe, and the hidden costs that rarely show up on a headline quote.
Whole-home repipe cost
A whole-home PEX repipe in the Upstate runs $3,700 to $7,350, with a full range of $2,500 to $10,000 depending on the home. Copper costs more: $7,350 to $13,800, and $18,000 to $20,000 or more on large homes with long pipe runs and many fixtures.
You do not always need to repipe the whole house. Repiping part of a home or a few problem fixtures runs $650 to $1,650. A useful rule of thumb is $450 to $1,800 per fixture, which helps you sanity-check a partial-job quote against the number of fixtures involved.
Across any of these jobs, labor is the largest share of the bill. Expect labor to account for 40 to 70 percent of the total, since repiping means opening walls, running new lines through the home, and connecting every fixture.
PEX vs copper
The material you choose shapes both the price and the experience of the job.
PEX
PEX is the residential standard in 2026. It is flexible, so it threads through walls and around corners with fewer connections, which cuts labor time and the number of failure points. It resists freeze damage better than copper and does not corrode. At $3,700 to $7,350 for a whole home, it is the budget-friendly and faster option, and it is what most Upstate homes get today.
Copper
Copper is the traditional choice and still respected for durability and a long track record. It is rigid, takes longer to install, and costs roughly twice as much: $7,350 to $13,800 for a whole home, climbing past $18,000 to $20,000 on large houses. Some homeowners still prefer it, but for most repipes, PEX delivers the performance at a lower price.
For the large majority of Upstate homeowners, PEX is the practical pick. Copper makes sense when a specific situation or preference calls for it, but it is no longer the default.
When a home needs a full repipe
A full repipe is warranted when the problem is the plumbing system itself, not a single bad section. Common signs include:
- Repeated leaks in different parts of the house
- Discolored or rusty water from corroding pipes
- Low water pressure throughout the home
- Old galvanized steel or polybutylene piping
- A home where small repairs keep adding up
If the trouble is isolated to one area or a couple of fixtures, a partial repipe at $650 to $1,650 may solve it. When leaks and pressure problems are spread across the house, paying to replace the whole system once usually beats chasing failures year after year.
What drives the cost
Two homes of the same size can still land on different quotes. These factors move the number most:
- Home size. More square footage means more linear feet of pipe and more labor.
- Fixture count. Every sink, toilet, tub, shower, and connection adds work. At $450 to $1,800 per fixture, the count matters.
- Access. Pipes in an open crawlspace or unfinished basement are cheaper to reach than pipes buried behind finished walls, in slabs, or in tight attics.
- Wall repair. Repiping means opening walls, and someone has to close them back up. How much drywall comes out directly affects the total.
Hidden costs to ask about
Two costs get left off headline quotes more than any others. Ask about both before you sign:
- Permit. A repipe typically needs a permit, which runs $50 to $800 depending on the jurisdiction and scope. A quote that ignores the permit is not complete.
- Drywall repair. Opening walls to run new pipe leaves holes, and patching, mudding, and painting runs $300 to $1,500 or more. Confirm whether your quote includes wall repair or stops at the plumbing.
Get the full scope in writing. A low quote that excludes the permit and drywall repair can end up costing more than a higher quote that covers everything. When you compare bids, make sure each one includes the same work so you are comparing real totals.
Frequently asked questions
How much does it cost to repipe a house in the Upstate? A whole-home PEX repipe runs $3,700 to $7,350, with a full range of $2,500 to $10,000. Copper runs $7,350 to $13,800, and more on large homes. Your final number depends on home size, fixture count, access, and wall repair.
Is PEX or copper better for a repipe? For most Upstate homes in 2026, PEX is the better value. It is flexible, resists freezing and corrosion, installs faster, and costs about half what copper does. Copper is durable and proven, but it is no longer the default choice for residential repipes.
Do I need to repipe my whole house, or just part of it? If leaks, low pressure, or discolored water show up across the home, a full repipe is usually the right call. If the problem is isolated to one area or a few fixtures, a partial repipe at $650 to $1,650 may be enough. A plumber can pinpoint whether the issue is systemwide or local.
What hidden costs should I ask about before repiping? Two stand out: the permit, which runs $50 to $800, and drywall repair, which runs $300 to $1,500 or more. Both are easy to leave off a headline quote. Confirm they are included so you are comparing complete bids, not just plumbing-only numbers.
