Cost to Repipe a House (2026): PEX vs. Copper
Quick answer
Repiping a typical US single-family home costs about $6,000 to $20,000 in 2026. PEX is the most common and affordable choice. Copper usually adds several thousand dollars for the same home. Large or multi-story homes can cost $25,000 or more.
Repiping means replacing the water supply pipes in your home. It is a big job, but in older homes with failing pipes it can stop leaks, low water pressure and rusty water for good.
PEX vs. copper
| PEX | Copper | |
|---|---|---|
| Material cost per foot | About $0.40 – $2 | About $2 – $8 |
| Typical whole-house cost | Lower | Several thousand dollars more |
| Install time | Faster | Slower |
| Lifespan | Long (manufacturers often rate 40+ years) | Very long (50+ years) |
| Good to know | Flexible, fewer fittings, resists freezing better | Very durable, can be affected by acidic water |
Labor is the biggest part of the bill, often around 70% of the project. That is why PEX, which is faster to install, usually lowers the total cost.
What changes the price
