Quick answer
HomeAdvisor puts a whole-house repipe at about $4.50 per square foot of house, so a 1,500 square foot home works out near $6,750 before wall repair, with labor about 70% of the total. Angi puts PEX at $0.40–$2 per foot and copper at $2–$8 per foot, which is why PEX repipes usually cost less. The number of bathrooms, the number of floors, access through a crawl space or slab, and drywall patching change the price most.

Repiping replaces a home's water supply lines, usually because the existing pipe is polybutylene, corroded galvanized steel, or copper with repeated pinhole leaks. It is a large job, but a predictable one, and most of the cost is labor.

What Changes the Price
- Bathrooms and fixtures. Each bathroom, kitchen and laundry adds runs and valves.
- Floors. A two-story house needs runs through walls and ceilings.
- Access. A crawl space or unfinished basement is easier than a slab, where lines are often rerouted through the attic or walls.
- Material. PEX costs less to buy and install than copper.
- Wall repair. Some quotes include patching, many do not.
- Permit. Most areas require one for a repipe.
PEX or Copper
| PEX | Copper | |
|---|---|---|
| Material cost | Lower | Higher |
| Joints | Fewer, flexible runs | More fittings |
| Freeze tolerance | Better | Can split |
| Sunlight | Must be kept out of UV | Not affected |
| Lifespan | Long | Long |

Is It Worth It?
When pipe is failing, patching leaks one at a time costs more over a few years and each leak risks water damage inside a wall. See polybutylene pipes, galvanized pipes, and what to do if one fails in pipe burst in wall.
