How Much Does It Cost to Repipe a House? (2026 Price Guide)
Whole-house repiping is one of the largest plumbing projects a homeowner can face — but it's also one of the most necessary when your existing pipes are corroded, leaking, or made from materials like galvanized steel or polybutylene. Here's exactly what it costs and what drives the price.
Average Cost to Repipe a House
Most homeowners pay $4,000–$15,000 to repipe an entire house, with the typical job landing between $6,000 and $8,000 for a complete PEX repipe of a mid-size home.
| House Size | PEX Repiping | Copper Repiping |
|---|---|---|
| Under 1,000 sq ft | $2,500–$5,000 | $4,000–$8,000 |
| 1,000–1,500 sq ft | $4,000–$6,000 | $8,000–$10,000 |
| 1,500–2,500 sq ft | $6,000–$10,000 | $10,000–$15,000 |
| 2,500+ sq ft | $10,000–$15,000 | $15,000–$20,000+ |
Labor accounts for roughly 70% of the total cost. Material choice has a significant impact on the remaining 30%.
PEX vs Copper: Which Pipe Should You Choose?
The two most common materials for whole-house repiping are PEX and copper. Here's how they compare:
PEX Pipe
- Material cost: $0.50–$2.00 per linear foot
- Lifespan: 25–50 years
- Advantages: Flexible — can be snaked through walls with minimal demolition. Resistant to freezing (it expands rather than bursting). No soldering required.
- Disadvantages: Not UV-resistant (cannot be used outdoors). Shorter track record than copper. Some municipalities restrict its use.
Copper Pipe
- Material cost: $2.00–$4.00 per linear foot
- Lifespan: 50–70+ years
- Advantages: Proven 100-year track record. Fully recyclable. Resistant to bacteria growth.
- Disadvantages: More expensive. Requires soldering (more labor time). More wall opening required since it doesn't flex around corners.
For most homeowners, PEX is the better value. The 40–60% material savings plus faster installation (less wall damage to repair) make it the choice of most professional plumbers today.
What Drives the Cost of Repiping
Number of Fixtures
Plumbers often quote by fixture count. Homes with fewer than 9 fixtures average around $4,600 to repipe; homes with 14 or more fixtures can exceed $11,000.
Access and Wall Damage
If pipes run through finished drywall, tile, or hardwood floors, opening and patching those surfaces adds cost. PEX minimizes this because of its flexibility. In worst-case scenarios with concrete slabs or tile floors over pipes, costs jump significantly.
Geographic Location
Labor markets vary widely. Expect to pay more in the Northeast (NY, MA, CT) and West Coast (CA, WA, OR), and less in the Midwest and Southeast.
Permit Fees
Whole-house repiping almost always requires a permit and inspection. Permit costs vary by municipality but typically add $200–$500 to the project.
Signs You Need to Repipe Your House
- Persistent brown or rust-colored water — especially common with galvanized steel pipes over 40 years old
- Frequent pinhole leaks — often a sign of copper corrosion in acidic water conditions
- Consistently low water pressure throughout the house (not just one fixture)
- Pipes made from polybutylene (gray plastic, common 1978–1995) — prone to failure, not insurable in some areas
- Major renovation — if you're already opening walls, it's the ideal time to replace aging pipes
How to Get an Accurate Quote
Get quotes from at least 3 licensed plumbers. A legitimate quote should include:
- A per-fixture or per-linear-foot breakdown
- The material brand and type
- Whether permit and inspection fees are included
- Whether drywall patching is included or separate
Avoid any plumber who quotes verbally without a written line-item estimate. Repiping is a large job — get everything in writing.
Frequently Asked Questions
How long does whole-house repiping take? Most jobs take 2–4 days for the plumbing work itself. Drywall patching and painting add additional time.
Will homeowners insurance cover repiping? Generally no — repiping is considered a maintenance issue, not sudden damage. However, if a pipe bursts and causes water damage, the damage repair (not the pipe replacement) may be covered.
Can I stay in my home during repiping? Yes for most of the job, but expect your water to be shut off for several hours each day. Plan accordingly.
