How Much Does It Cost to Repipe a House in 2026?
When your galvanized pipes keep springing pinhole leaks or the water runs brown every morning, repiping stops being a "someday" project. The typical cost to repipe a house in 2026 ranges from $4,000 to $15,000, with most homeowners paying around $8,000 for a whole-house PEX repipe. Copper costs 50-100% more. The final number depends on your home's size, the number of fixtures, pipe accessibility, and your local labor market. Here is the full breakdown.
Average Cost to Repipe a House in 2026
A whole-house repipe means replacing all hot and cold water supply lines — not the drains. (Drain replacement is a separate project; see our sewer line guides for that side of the system.) Nationally, PEX repipes average about $4-$7 per square foot of home, while copper runs $8-$12 per square foot.
| Repipe material | Cost per sq ft | Typical total (2,000 sq ft home) |
|---|---|---|
| PEX (cross-linked polyethylene) | $4 - $7 | $8,000 - $14,000 |
| Copper (Type L) | $8 - $12 | $16,000 - $24,000 |
| CPVC | $3 - $6 | $6,000 - $12,000 |
CPVC is the budget option but has fallen out of favor with many plumbers — it becomes brittle with age and is harder to work with than PEX. In 2026, roughly 80% of residential repipes use PEX, and that share keeps growing as more plumbers standardize on it. For context on material differences, our pipe comparison guides explain how plumbers think about plastic vs metal systems generally.
Repipe Cost by Home Size
Square footage is a rough proxy; what really matters is fixture count (each sink, toilet, shower, and appliance is a connection point). Still, size-based ranges are how most homeowners first budget:
| Home size | Bedrooms/baths (typical) | PEX repipe range | Copper repipe range |
|---|---|---|---|
| 1,000 sq ft | 2 bed / 1 bath | $4,000 - $7,000 | $8,000 - $12,000 |
| 1,500 sq ft | 3 bed / 2 bath | $6,000 - $10,500 | $12,000 - $18,000 |
| 2,000 sq ft | 4 bed / 2.5 bath | $8,000 - $14,000 | $16,000 - $24,000 |
| 2,500 sq ft | 4-5 bed / 3 bath | $10,000 - $17,500 | $20,000 - $30,000 |
| 3,000+ sq ft | 5+ bed / 4 bath | $12,000 - $21,000+ | $24,000 - $36,000+ |
Two-story homes cost 15-25% more than single-story homes of the same square footage because running pipe between floors means more wall and ceiling openings. Slab foundations add cost too — rerouting overhead instead of jackhammering the slab is standard practice and adds labor, though it avoids the mess, noise, and concrete repair bills that come with breaking through the floor.
PEX vs Copper Repipe: Honest Comparison
PEX dominates modern repipes for good reasons: it is flexible (fewer fittings, fewer leak points), freeze-resistant, quiet, and installs fast — a crew can repipe an average home in 2-3 days. It costs half as much as copper and carries 25-year manufacturer warranties. Downsides: it cannot be used outdoors (UV degrades it), some homeowners dislike plastic supply lines on principle, and a small number of municipalities still restrict it.
Copper is the premium choice: 50-70 year lifespan, naturally antimicrobial, UV-proof, and familiar to every plumber. It also adds perceived value at resale in some markets. The downsides are price (double PEX), longer install time (4-5 days with soldering), vulnerability to pinhole leaks in aggressive water chemistry, and theft risk on job sites.
Our take: choose PEX unless you have a specific reason for copper (local code preference, personal preference, or a high-end home where buyers expect it). The performance gap for residential use does not justify double the price for most families. Either way, insist on Type L copper (not thinner Type M) or name-brand PEX-A with expansion fittings if you go the PEX route.
What a Repipe Quote Should Include
A proper repipe bid covers more than pipe. Verify these line items before signing:
- All supply lines — hot and cold to every fixture, plus the main shutoff valve and pressure regulator if needed.
- Permits and inspections — $200-$500; required nearly everywhere for this scope of work.
- Drywall repair — the biggest variable. Some plumbers include patching ($1,000-$3,000 value); others leave you to hire a drywall contractor. Get it in writing.
- New valves and supply stops at every fixture — non-negotiable; old stops fail when disturbed.
- Water heater connections — reworking the final connections to the heater.
- Pressure test and inspection before walls are closed.
What is usually not included: drain/waste pipe replacement, fixture replacement (toilets, faucets stay), and finish painting after drywall patching. If a bid seems dramatically cheaper than others, drywall repair is the most commonly omitted item — a $6,000 bid without patching is really a $9,000 bid.
7 Signs Your House Needs Repiping
You do not repipe on a schedule; you repipe on symptoms. Call for an evaluation if you notice:
- Discolored water — brown, yellow, or rusty water, especially from hot taps, signals corroding galvanized or iron pipe.
- Recurring pinhole leaks — two or more leaks in a year means the system is failing, not the individual spots.
- Low water pressure throughout the house — corrosion narrows old galvanized pipe from the inside.
- Visible corrosion on exposed pipe — flaking, green/white crust on copper, or rust on galvanized.
- Polybutylene pipe (gray plastic, 1978-1995) — notorious for sudden failure; replacement is a matter of when, not if.
- Lead pipes or lead solder — a health issue, not just a maintenance one; test your water.
- Your home is 50+ years old with original galvanized supply lines — they are living on borrowed time.
Repipe Timeline: What to Expect Day by Day
Knowing the sequence takes the mystery (and much of the stress) out of the project. Here is how a typical 2,000 sq ft PEX repipe unfolds:
Day 1 — Protection and demolition. The crew lays floor protection, shuts off the main, drains the system, and cuts access openings in drywall — usually behind fixtures and along pipe runs. Expect noise and dust; this is the messiest day. Water is off during work hours and restored each evening.
Day 2 — Rough-in. New PEX lines go in: home runs from a central manifold (or trunk-and-branch) to each fixture, new shutoff valves, and connections stubbed out at every location. A good crew completes most or all of the pipe installation in a single day for an average home.
Day 3 — Connections, testing, inspection. Final fixture connections, the system is pressure-tested, and the municipal inspector signs off — this inspection is why the permit matters. Any deficiencies get corrected the same day.
Days 4-5 — Patch and paint. Drywall patches go in, then texture and paint (often by a separate finisher). Copper repipes add 1-2 days to the rough-in phase for soldering and the extra fittings involved.
Prepare by clearing under-sink cabinets, moving furniture away from walls where work will happen, and planning for workers to need attic or crawlspace access. Keep pets secured and expect the crew to need your driveway for their truck and pipe stock. None of this is disruptive enough to require moving out — but the first day's drywall cutting is genuinely loud, so plan accordingly if you work from home.
How to Save on a Repipe
Timing is leverage: a planned repipe costs 30-50% less than an emergency repipe after a major leak, when you are paying panic rates and water damage restoration on top. Get four quotes — repipe pricing varies more than almost any other plumbing job because labor methods differ so much between companies.
Ask each bidder the same questions: PEX-A or PEX-B (and why), expansion vs crimp fittings, exactly what drywall repair is included, and how many days water will be off (usually just during work hours, restored each evening). Consider bundling: if the water heater is 10+ years old, replacing it during the repipe saves a second round of labor. And check your homeowner's insurance — while repiping itself is maintenance (not covered), resulting water damage from a burst pipe sometimes is, which can offset emergency costs.
