Repiping is one of the bigger checks a homeowner writes, so it’s worth understanding before you get a quote — both what’s fair, and whether you truly need a whole-home repipe or just a targeted fix. Here are the real 2026 numbers and how a plumber thinks about the job.
What a repipe costs in 2026
| Scope | PEX | Copper |
|---|---|---|
| Small home / condo (1–2 bath) | $2,500–$5,000 | $5,000–$9,000 |
| Average home (2–3 bath) | $4,000–$8,000 | $8,000–$15,000 |
| Large home (3+ bath, 2 story) | $7,000–$12,000+ | $12,000–$25,000+ |
| Partial / single problem line | $800–$2,500 | $1,500–$4,000 |
PEX is typically 30–50% cheaper than copper — the material costs less and it installs far faster (fewer fittings, no soldering, snakes through walls easily). Copper costs more but some homeowners still prefer it; the trade-offs are laid out in PEX vs copper vs CPVC and SharkBite vs soldered copper.
Where the Money Actually Goes
The pipe is the cheap part. That is the single most useful thing to understand before you read a repipe quote.
Per foot, the material barely registers: PEX runs $0.40–$2 per linear foot, CPVC $0.50–$1, and copper $2–$8 (Angi, 2026). Across a whole house that is hundreds of dollars of pipe, not thousands. Angi puts labor at roughly 70% of the total bill, working out to about $1,200 per fixture.
If CPVC is on your shortlist, CPVC vs PVC pipe covers which of the two plastics belongs on a hot line and which does not.
Which is exactly why two quotes for the “same” job can differ by thousands. You are not buying pipe. You are buying access — opening walls and ceilings, working around whatever is already in the way, and putting it all back. A house with a crawlspace and an unfinished basement is a completely different job from a slab house with tiled walls, even when the pipe list is identical.
Angi’s per-fixture figures show the spread: sink $350–$800, dishwasher $400–$800, washing machine $350–$1,500, shower $600–$1,600, water heater $700–$1,800. The expensive ones are the fixtures buried behind tile and framing.
Two things follow from that. Ask for quotes that break out material and fixture count separately, so you are comparing like with like instead of two lump sums. And if walls are already coming open for a remodel, that is the cheapest a repipe will ever be — the expensive half of the job is already paid for.
What actually drives your price
- Home size & number of fixtures — more bathrooms and a bigger footprint mean more pipe and more labor.
- Access: a home on a crawlspace or with an unfinished basement is far cheaper to repipe than a slab foundation or finished walls (which means cutting and patching drywall). That same basement is where groundwater collects, so it’s worth keeping an unfinished basement dry with a reliable sump pump before you invest in new pipe.
- One story vs. two — running new lines up to a second floor adds labor.
- Drywall repair & finish — opening and re-closing walls can be a big slice of the total; ask whether the quote includes patching.
- Material choice — PEX vs copper, as above.
Do you actually need a repipe?
A whole-home repipe is the right call when the pipes themselves are failing — not for a single leak. Real signs:
- Polybutylene or old galvanized steel pipe. Poly is failure-prone and galvanized corrodes shut from the inside — both are classic repipe candidates.
- Repeated pinhole leaks in copper (a sign the whole system is going).
- Chronically low pressure from corroded, narrowed lines.
- Rusty or discolored water that isn’t the water heater.
If it’s a single leak or one bad run, you don’t need to repipe the house — a spot repair or a partial is far cheaper. And whatever a quote says, sanity-check the labor against typical plumber rates.
Should you DIY a repipe?
Honestly — usually not. PEX has made small repairs and partial runs DIY-friendly, but a full repipe involves permits, opening walls, getting every connection right behind drywall, and passing inspection. For the whole house, this is a licensed-plumber job; the cost of one hidden leak inside a finished wall erases any labor you’d save. A confident DIYer can absolutely handle a single accessible line.
If your home still has old galvanized steel plumbing, see whether you should replace galvanized pipes before you budget a full repipe.
Frequently asked questions
How much does it cost to repipe a house? For an average 2–3 bath home, roughly $4,000–$8,000 in PEX or $8,000–$15,000 in copper. Small homes and partials cost less; large two-story homes cost more.
Is PEX or copper better for a repipe? PEX is cheaper, faster to install, and resists freeze-bursts; copper is long-proven and some prefer it. For most repipes, PEX is the practical choice — see the full comparison.
How long does a repipe take? Most homes are 2–5 days, depending on size, access, and drywall repair. PEX is faster than copper.
Do I need to repipe for one leak? No. A single leak is a spot repair. Whole-home repiping is for systemic failure — polybutylene, galvanized, or repeated pinhole leaks.
