How Much Does It Cost to Repipe a House in California?
Most homeowners spend between $1,500 and $15,000 to repipe a house, one national cost guide reports. Its national average is $7,500. The same guide scales its numbers to Los Angeles prices, where most homeowners pay around $8,520. The size of the house and the pipe you choose drive much of that spread.
These are market numbers from national cost guides, not our price list. ASC Plumbing does whole house and partial repipes around Salinas and the Monterey Bay Area. We look at the pipe you have now, then put the repipe quote in writing.
What does a whole house repipe cost in California?
National cost guides measure different things, so each row below names its source. None of the guides we read publishes a figure for Salinas or the Monterey Bay Area.
| What the number covers | Market range | Source |
|---|---|---|
| Repiping a house, national | $1,500 to $15,000, average $7,500 | A national cost guide, 2026 |
| Repiping a house, Los Angeles | $1,704 to $17,040, typical about $8,520 | The same guide, scaled to local prices |
| Repiping a 1,500 square foot house | $2,280 to $4,080 on average | A second national guide, 2025 |
| Repiping a 2,000 square foot house | $3,000 to $16,000, average about $6,500 | A third national guide, 2024 |
| Permit fee | $50 to $500 | Two of the national guides |
| Patching drywall after a repipe | About $300 to $900 or more | The first guide |
Labor makes up about 70 percent of a repipe bill, the first guide says. That makes local wages part of local prices. The U.S. Bureau of Labor Statistics tracks plumber wages by area. Here is the mean hourly wage for plumbers and pipefitters in May 2025:
| Area | Mean wage, May 2025 |
|---|---|
| Salinas metro area | $34.95 an hour |
| Santa Cruz and Watsonville metro area | $37.37 an hour |
| California | $39.58 an hour |
| San Jose metro area | $54.94 an hour |
| United States | $34.70 an hour |
Wages in the Salinas metro area sit close to the national mean. Wages are only one part of a price. Still, they help explain why the same repipe can cost more in some California markets than in others.
How much more does copper cost than PEX?
Copper costs more than PEX in every national guide we read. The gap shows up in the pipe itself and in the labor to put it in.
| Pipe | Pipe, per linear foot (2026 guide) | Installed, per linear foot (2024 guide) | 2,000 square foot house (2025 guide) |
|---|---|---|---|
| PEX | $0.40 to $2 | $1.50 to $4 | $2,000 to $4,000 |
| Copper | $2 to $8 | $4 to $12 | $8,000 to $16,000 |
PEX is a flexible plastic pipe. It bends around corners and can be snaked through small holes in the walls, one guide notes. Copper is rigid metal pipe. Each turn and branch takes a fitting, soldered or pressed onto the pipe, and that adds hours.
Both are standard pipes for a repipe, and the choice is yours. The written quote names the pipe that goes in.
What drives the price of a repipe?
The guides name much the same cost drivers. Here is what each one does to the price.
- House size and fixtures. Each sink, toilet, tub and appliance needs its own line. More fixtures mean more pipe and more hours.
- Stories. A second story needs lines run between floors, which takes more pipe than a one-story layout.
- A slab or a crawlspace. Pipe under a concrete slab costs more to reach than pipe behind drywall, one guide says. A hard-to-reach crawlspace adds cost too. The old lines are often left in place, with new ones run through the attic or the crawlspace.
- Access and wall patching. A repipe opens walls and ceilings in places to reach the pipe. Patching may be a separate line on the quote, or a separate trade.
- The permit. The city or county building office sets the fee, and a permit normally comes with an inspection.
- Removing old pipe. One guide puts removal at $1,000 to $4,500, though it is often part of the repipe price.
One guide notes that replacing a water heater during a repipe is a common pairing. Our water heater replacement cost guide covers that price.
How much does a partial repipe cost?
A partial repipe replaces the lines to one part of the house, such as a bathroom or the kitchen. One national guide puts repiping a single fixture at about $1,200 on average. Another lists $450 to $1,800 per fixture or small section of pipe.
A partial repipe fits when one area has failed and the rest of the pipe is sound. If the rest is the same old pipe, ask for a whole house price too, so you can compare. A remodel is a good time for it, because some walls are already open. The new lines can go in with the plumbing rough-in for the remodel.
What are the signs a house needs a repipe?
Old galvanized steel pipe is a common reason for a repipe. A California water utility explains that this pipe is iron or steel with a zinc coating. Once the zinc wears away, the iron starts to rust. Deposits build up inside, and in time the pipe leaks.
The same utility says galvanized pipe was common before the 1960s. One national guide puts its life at 20 to 50 years. About a quarter of the housing in Salinas was built before 1960, Census figures show. The share tops half in Pacific Grove and Carmel-by-the-Sea.
Watch for these signs too:
- Low water pressure at more than one fixture
- Rusty or discolored water that lasts more than a moment
- Leaks that keep coming back after repairs
- Corrosion you can see on exposed pipe
A magnet test helps. A magnet sticks to galvanized steel but not to copper or plastic, the utility notes. Test a water pipe, because a gas line can be steel too.
One leak in sound pipe calls for a plumbing repair. A repipe makes sense when leaks keep turning up in new spots.
How do you get a repipe price for your house?
A price for your house starts with a look at its pipe. We look at the job, then put the quote in writing. It names the pipe and spells out what is included. Read how the work runs on our repiping service page, or call or text (831) 262-9943.
