Plumbing and repipe cost in Oregon
In Oregon, plumbing work prices run above the national average — whether you're in Portland, Salem, or Eugene. Here's what a complete, permitted job should cost, and how to tell whether the quote in your hand is fair.
Typical Oregon range
$1,600 – $21,800
Water heater replacements often run $1,500–$5,000; whole-home repipes and sewer line replacements commonly run $4,000–$20,000 or more.
Included at this price: Labor, specified pipe and fixtures, permit and inspection handling, pressure testing, and cleanup when specified; wall, yard, or concrete repair varies by bid.
Oregon prices by project type
| Project | Oregon range | Unit check |
|---|---|---|
| Whole-home repipe (PEX or copper) | $4,400 – $17,400 | Home size, fixture count, pipe material, and access drive the range; drywall repair is often separate. |
| Sewer line repair or replacement | $3,300 – $27,300 | Trenchless lining or bursting and traditional excavation price very differently; depth and length matter. |
| Tank or tankless water heater | $1,600 – $7,100 | Tank swaps often run $1,500–$3,500; tankless conversions cost more when gas, venting, or electrical upgrades are needed. |
| Main water service line replacement | $1,600 – $7,600 | Run length, depth, trenchless options, and driveway or landscaping crossings drive cost. |
