How Much Does It Cost to Repipe a House?
The cost to repipe a house runs from about $3,500 to $25,000, and most homeowners land near $7,500 to $12,000 for a whole-house job. Two things move that number more than anything else: your home size and whether you choose PEX or copper. PEX runs 40% to 60% cheaper installed. Below are prices by size and material, plus the honest signs you actually need a repipe.
Cost to repipe a house by size and material
Repipe pricing tracks home size and pipe material almost directly. A small one-bath home in PEX may cost $3,500, while a large two-story home in copper can pass $25,000. The table below crosses both factors so you can find your home and compare the two common materials side by side. Figures are installed, including labor.
| Home size | Bathrooms | PEX (installed) | Copper (installed) |
|---|---|---|---|
| Small, single story (about 1,000 to 1,500 sq ft) | 1 to 2 | $3,500 to $8,000 | $6,000 to $13,000 |
| Mid-size (about 1,500 to 2,500 sq ft) | 2 to 3 | $5,000 to $11,000 | $9,000 to $18,000 |
| Large, often two story (2,500 sq ft and up) | 3 or more | $8,000 to $15,000 | $13,000 to $25,000 |
Two homes with the same square footage can still come back with different quotes once a plumber is inside the crawl space or attic. Fixture count, the number of vertical runs, and foundation type all shift the labor hours. Treat these bands as a planning range, then confirm with local bids.
PEX vs copper: why the price gap is so wide
PEX costs less because the material is cheaper per foot and it installs far faster. PEX tubing runs about $0.40 to $2 per linear foot; copper runs $2 to $8. PEX is flexible and joins with mechanical fittings, so a crew can pull it through walls without cutting and soldering every joint. That cuts labor, which is where most of the savings live.
| Material | Cost per linear foot | Typical lifespan | Install time (whole house) |
|---|---|---|---|
| PEX | $0.40 to $2 | 40 to 100 years | 1 to 3 days |
| Copper | $2 to $8 | 50 to 100 years | 3 to 5 days |
| CPVC | $0.50 to $1 | 40 to 70 years | 2 to 4 days |
Copper still has a case. It handles high heat, some buyers and inspectors prefer it, and it can read as a premium feature at resale in certain markets. But for most homeowners choosing on budget and speed, PEX is the default in 2026. For a deeper side-by-side on durability and where each material wins, see how PEX and copper compare beyond price.
What drives the labor and the hidden costs
Labor is often 50% to 70% of a repipe bill. The pipe itself is a minor line item next to the hours spent opening walls, running new lines, and patching. Access is the swing factor: a single-story home over a crawl space is cheap to reach, while a two-story slab home with tiled bathrooms costs far more to open and close.
Budget for the extras that ride along with the pipe work, since they are easy to forget in an early estimate.
| Add-on cost | Typical range |
|---|---|
| Permits | $50 to $500 |
| Inspection | $250 to $1,200 |
| Drywall patch and paint | $500 to $2,000 |
| Water main line replacement | $600 to $2,500 |
| Water heater swap during the job | $600 to $1,800 |
If your tank is more than 10 years old, it is often smart to replace the water heater at the same time, since the walls are already open and the plumber is already on site. Doing both in one visit saves a second round of labor.
The honest signs you actually need a repipe
You likely need a full repipe when the problem is the pipe material or age, not a single fitting. The strongest triggers are galvanized steel pipe (common in homes built before 1970), polybutylene (the grey plastic pipe used from roughly 1978 to 1995), repeated pinhole leaks in copper, and rusty or brown water at multiple taps. These get more expensive with every patch.
- Galvanized steel pipe. It corrodes from the inside, chokes pressure, and stains water. Once one section fails, the rest usually follow.
- Polybutylene pipe. Prone to sudden failure and hard to insure. Many plumbers recommend full replacement rather than repair.
- Repeated pinhole leaks. Two or more copper leaks in a year usually means the whole system is thinning, not one bad spot.
- Rusty, brown, or metallic water. Discoloration at several fixtures points to pipe interior corrosion, not the fixture.
- Whole-house low pressure. Weak flow at every tap, not just one, suggests scale or corrosion throughout the lines.
- Original plumbing past 40 years. Time to have it assessed even if it has not failed yet.
When it is a repair, not a repipe
A full repipe is the wrong spend when the problem is isolated. One leak at a single joint, weak pressure at just one faucet, or a fixture running slow usually calls for a targeted fix costing a few hundred dollars, not five figures. Do not let a whole-house quote talk you out of a simple repair.
- Low pressure at one faucet. Often a clogged aerator or a bad supply valve, a same-day fix.
- A single visible leak. One dripping joint on otherwise sound copper or PEX can be repaired in place.
- One isolated slab leak. A reroute of that one line is often cheaper than repiping the whole home.
If a pipe fails suddenly while you decide, follow the steps for what to do when a pipe bursts to limit water damage before the plumber arrives. Fast shutoff is what keeps a leak from becoming a repipe plus a restoration bill.
How to budget and get an accurate quote
Get at least three itemized bids and make sure each one lists material, labor, permits, and drywall patching separately. A quote that bundles everything into one number hides where your money goes and makes comparison hard. Ask what happens to the walls after the pipe work.
- Confirm your current pipe material and home age, since those set the urgency.
- Decide PEX or copper before you call, so every bid quotes the same material.
- Ask each plumber to break out labor, material, permit, and patch costs.
- Confirm who handles drywall repair and repainting, and whether it is included.
- Check that the plumber pulls a permit and schedules the required inspection.
When you are ready to compare bids, get quotes from licensed plumbers near you and hold each one to the same itemized format. A clear, line-by-line estimate is the best protection against surprise costs on a job this size.
Frequently asked questions
How much does it cost to repipe a 1,500 sq ft house?
A 1,500 square foot home with two bathrooms often runs $5,000 to $11,000 in PEX and $9,000 to $18,000 in copper, installed. The gap comes from material price and labor hours. Single-story homes with crawl space access sit at the lower end; slab foundations and tiled walls push the number up.
Is PEX or copper better for a whole-house repipe?
PEX costs 40% to 60% less, installs in 1 to 3 days, and resists freeze bursts and corrosion, which is why most 2026 repipes use it. Copper lasts 50 or more years, tolerates high heat, and some buyers prefer it. For most homeowners on a budget, PEX wins; copper wins on longevity and resale in some markets.
Is it worth repiping a house?
A repipe is often worth it when you have galvanized steel or polybutylene pipe, repeated pinhole leaks, or rusty water, because those problems get more expensive with every patch. A full repipe restores pressure, removes leak risk, and can help resale. For a single isolated leak, a targeted repair usually makes more sense.
How long does a whole-house repipe take?
Most whole-house repipes take 1 to 5 days. PEX jobs often finish in 1 to 3 days because the tubing is flexible and uses mechanical fittings. Copper takes 3 to 5 days since every joint is soldered. Drywall patching and inspection may add a day or two after the pipe work is done.
Does homeowners insurance cover repiping?
Homeowners insurance often covers sudden water damage from a burst pipe but rarely pays to replace the pipes themselves, since a repipe is treated as maintenance or an upgrade. Coverage varies by policy and state. If old pipes caused a covered loss, some insurers may pay for the damaged section, not the whole system.
