A repipe rarely comes out of nowhere. It's usually the fourth pinhole leak this year, or a plumber pointing at galvanized steel pipe in your basement and asking how old the house is. Once you're facing a whole-home repipe, the range of prices you'll hear from different contractors can be enormous — and that gap is exactly why it pays to understand what's driving the number before you sign anything.
How Much Does It Cost to Repipe a House?
According to Angi's 2026 cost data, a whole-house repipe generally runs $1,500 to $15,000, with most homeowners paying somewhere around $7,500. That's a wide band, and the material you choose accounts for most of the spread.
| Material | Typical Whole-Home Range | 1,500 Sq. Ft. Home |
|---|---|---|
| PEX | $4,000–$8,000 | $5,500–$11,000 |
| Copper | $8,000–$15,000 | $12,000–$22,000 |
These are national ranges pulled from published cost guides — your local quotes will differ based on labor rates, permit costs, and how your house is built. That's also the core reason to collect more than one bid: two licensed plumbers can look at the same job and land $5,000 apart, and without a second or third quote you have no way to know which number reflects a fair local price and which one is padded.
Copper vs. PEX: Which Costs Less?
PEX is the cheaper option in almost every case, and it's become the default choice for most residential repipes. Installed cost runs roughly $3.50–$7.00 per square foot for PEX versus $8.00–$14.00 per square foot for copper. Because PEX uses flexible tubing with crimped fittings instead of soldered joints, it also installs faster — which matters, since labor typically makes up the majority of the total bill.
Copper still has fans. It's been used in home plumbing for generations, it doesn't degrade from UV exposure the way exposed PEX can, and some homeowners prefer it for resale reasons in older, higher-end homes. But for most whole-house jobs, PEX delivers comparable longevity — manufacturers generally rate it for 30 to 50 years of service, close to the 50-to-70-year range typically cited for copper — at 40 to 60 percent less cost.
What Affects the Price of a Repipe?
A handful of factors move the number up or down:
- Home size and number of bathrooms. More fixtures means more pipe runs and more labor hours.
- Wall access. Open crawl spaces and basements are cheap to work in. Repiping through finished walls, slab foundations, or multi-story construction adds drywall repair and patching costs on top of the plumbing itself.
- Number of stories. A two-story home costs more to repipe than a single-story home of the same square footage.
- Permits and inspections. Most municipalities require a permit for a whole-house repipe, and that fee is typically separate from the plumber's quote.
- What you're replacing. Swapping old galvanized steel for PEX is a more involved job than replacing an already-modern system.
None of these are fixed costs — they're variables a plumber estimates on-site, which is another reason a single quote isn't enough information to judge whether a price is reasonable.
How Long Does Repiping Take?
Most whole-house repipes take 2 to 5 days, with water shut off for roughly 8 to 10 hours during working hours each day. Smaller homes with one or two bathrooms often wrap up in 2 to 3 days; larger homes with four or more bathrooms can run closer to a week. PEX jobs tend to move faster than copper because there's no soldering involved. Many plumbers will restore water service overnight so your household isn't without running water for days at a stretch.
Do You Actually Need a Full Repipe?
Not every plumbing problem calls for repiping the whole house. Signs that point toward a full repipe rather than a spot repair include:
- Frequent or recurring leaks in different parts of the house
- Rusty, discolored, or metallic-tasting water
- Noticeably low water pressure throughout the house, not just at one fixture
- Visible galvanized steel or old lead piping
- Pipes that are original to a house built before the 1970s
If you're dealing with a single leak rather than a pattern of failures, a targeted repair may be all you need — see our guide on what it costs to fix a leaking pipe before assuming a full repipe is necessary. And if the symptom you noticed was a spike in your utility bill rather than a visible leak, it's worth ruling out a hidden leak first with our water bill checklist.
What to Do About It
If a plumber has told you that you need a repipe, don't treat their number as the number. Get quotes from at least two or three licensed, local plumbers before deciding on material or contractor — the spread between bids on a job this size is often thousands of dollars, and the only way to know a price is fair is to have something to compare it against. Ask each plumber to specify material (PEX or copper), estimated timeline, whether drywall repair is included, and whether the permit fee is separate. If your water heater is also aging out, it's worth asking whether bundling that replacement into the same project saves on labor — our water heater replacement cost guide covers what that job runs on its own.
