How much does it cost to repipe a house?
Repiping a house costs $1,500 to $15,000 according to Angi, with most homeowners paying around $7,500.
HomeGuide brackets the same job at $2,000 to $15,000 for a whole home, and prices a straightforward repipe of an existing house at $0.40 to $2.00 per linear foot of pipe. The spread between the floor and the ceiling is not padding — it is the difference between PEX and copper, and between a one-bath ranch and a three-bath two-story.

Repipe cost with PEX versus copper
| Material | Per linear foot (Angi) | 2,000 sq ft home (HomeGuide) |
|---|---|---|
| PEX | $0.40 – $2 | $2,000 – $4,000 |
| CPVC | $0.50 – $1 | Not published |
| Copper | $2 – $8 | $8,000 – $16,000 |
For the in-between sizes: HomeGuide prices replumbing a 1,500 square foot home at $2,280 to $4,080, and larger homes scale up from there by their pipe footage. Angi notes many plumbers prefer PEX because it does not corrode, resists freezing, and snakes through walls without the joints copper needs at every turn.
Why labor is most of the repipe bill
Angi says labor makes up about 70% of a repiping total — around $5,250 on its average job — because the work is opening walls, running new lines, and closing everything back up. It prices the drywall side at roughly $300 for small patches up to $900 or more for bigger repairs, and permits at $50 to $500. The pipe itself is the cheap part of a repipe.

Signs a house actually needs a repipe
- Galvanized or lead pipes, or pipes over 60 years old — Angi's list of replacement triggers starts here.
- Recurring leaks: patching one section only to find the next one failing.
- Discolored water, or water that smells or tastes wrong at the tap.
- Water pressure that has drifted low across the whole house, not one fixture.
One add-on worth planning rather than discovering: Angi says pairing a water heater replacement with a repipe is common, at $850 to $1,750 on average, since the plumber is already opening the system end to end.

Questions people ask next
- How much does it cost to repipe a 2,000 square foot house with PEX?
- HomeGuide publishes $2,000 to $4,000 to repipe a 2,000 square foot home with PEX, at $0.40 to $0.50 per linear foot of tubing. The house's fixture count and how hard the walls are to open move the number inside that band.
- How much does it cost to repipe a 2,000 square foot house with copper?
- HomeGuide publishes $8,000 to $16,000 for the same house in copper, at $3 to $8 per linear foot installed. Copper's material premium is the whole difference — the labor of opening walls is similar either way.
- How long does repiping a house take?
- Angi says a few days for small homes and up to several weeks for large multistory homes with many fixtures. Water is typically off only for portions of the work, and a good crew will tell you the outage windows in advance.
- Is repiping a house worth it?
- Angi's framing: new pipes can last 50 to 100 years, and a repipe ends the cycle of paying for leak after leak on a failing system. If your pipes are galvanized, lead, or past 60 years old, the question is usually when rather than whether.
