If you’re renovating your home or replacing old pipes, you’ve probably asked yourself: “How much does it cost to install copper plumbing?” It’s a smart question—copper is durable and trusted, but it’s also one of the pricier options on the market. Whether you’re a homeowner planning a bathroom upgrade or a DIYer weighing your options, this guide breaks down real-world costs, hidden factors, and what you actually pay in 2024.
What Is Copper Plumbing—and Why Do Homeowners Choose It?
Copper plumbing uses copper pipes to carry water throughout a home. Known for its corrosion resistance, longevity (50+ years), and bacterial resistance, copper has been a go-to material in U.S. homes since the 1960s. Unlike PVC or PEX, copper doesn’t leach chemicals and handles high water pressure with ease.
According to the U.S. Environmental Protection Agency (EPA) , copper is safe for drinking water systems when installed correctly—making it a top choice for health-conscious homeowners.
Average Cost to Install Copper Plumbing in 2024
The national average cost to install copper plumbing ranges from $3,000 to $12,000, depending on your home’s size, layout, and labor rates. Here’s a detailed breakdown:
| Per linear foot (materials only) | $3 – $8 |
| Labor (per hour) | $75 – $150 |
| Full repipe (1,500 sq ft home) | $8,000 – $12,000 |
| Partial replacement (e.g., kitchen only) | $1,500 – $4,000 |
💡 Real-World Example: A homeowner in Austin, TX, paid $9,200 in 2023 to fully repipe their 1,800 sq ft house with Type L copper—a common residential grade.
What Factors Affect Copper Plumbing Installation Costs?
Several variables influence your final bill. Understanding these helps you avoid surprise expenses.
1. Type of Copper Pipe
There are three main types used in homes:
- Type M: Thinnest wall, cheapest ($2–$4/ft). Best for low-pressure applications.
- Type L: Standard for residential main lines ($4–$7/ft). More durable.
- Type K: Thickest, used for underground or high-pressure lines ($6–$10/ft).
Most U.S. contractors recommend Type L for whole-house installations due to its balance of cost and strength.
2. Home Size and Layout
A 2-bedroom condo may cost $3,500 to repipe, while a 4-bedroom colonial with multiple bathrooms can exceed $11,000. Complex layouts (e.g., multi-story homes, finished basements) increase labor time.
3. Accessibility
If walls are already open (during a renovation), costs drop by 20–30%. But if plumbers must cut into drywall, patch, and repaint, add $1,000–$3,000 for restoration.
4. Local Labor Rates
Plumbers in New York City charge more than those in rural Kansas. Use tools like HomeAdvisor or Angi to compare local quotes.
5. Permits and Inspections
Most cities require plumbing permits ($50–$300) and inspections to ensure code compliance—don’t skip this step!
Copper vs. PEX vs. PVC: Cost and Performance Comparison
Still debating materials? Here’s how copper stacks up:
| Cost per ft (installed) | $8–$15 | $4–$8 | $2–$5 |
| Lifespan | 50+ years | 25–40 years | 25–40 years |
| Freeze Resistance | Poor (can burst) | Excellent | Moderate |
| Eco-Friendly | Highly recyclable | Not recyclable | Recyclable but less durable |
| Installation Speed | Slow (soldering required) | Fast (crimp/clamp) | Fast (glue joints) |
While PEX is cheaper and faster to install, copper remains the gold standard for durability and resale value—especially in high-end markets.
Step-by-Step: What Happens During a Copper Plumbing Installation?
If you’re hiring a pro (recommended!), here’s what to expect:
- Assessment & Quote
A licensed plumber inspects your current system and provides a detailed estimate. - Permit Application
Your contractor files for necessary permits (usually included in the quote). - Shut Off Water & Drain Lines
The main water valve is closed, and pipes are drained to prevent leaks. - Remove Old Pipes
Existing pipes (galvanized steel, CPVC, etc.) are cut out carefully. - Install New Copper Pipes
- Measure and cut copper tubing to length.
- Clean ends with emery cloth.
- Apply flux, then solder joints at 650–750°F using lead-free solder.
- Pressure-test the system with 60–80 PSI of air or water for 15 minutes to check for leaks.
- Restore Walls & Final Inspection
Drywall is patched, painted, and the city inspector approves the work.
⚠️ Warning: DIY copper plumbing is risky. Improper soldering can cause leaks or fire hazards. Always hire a licensed, insured plumber.
Pros and Cons of Copper Plumbing
✅ Advantages

- Resists bacteria growth (ideal for potable water)
- Adds home value—buyers trust copper systems
- 100% recyclable (eco-friendly at end-of-life)
❌ Disadvantages
- High upfront cost (2–3x more than PEX)
- Vulnerable to freezing (pipes can burst if water freezes inside)
- Requires skilled labor (not beginner-friendly)
- Price volatility—copper prices fluctuate with global markets

Frequently Asked Questions (FAQ)
Q: Is copper plumbing worth the cost?
A: Yes—if you plan to stay in your home long-term or sell in a competitive market. Its durability and clean water delivery justify the investment for many homeowners.
Q: How long does copper plumbing installation take?
A: A full-house repipe typically takes 3–7 days, depending on home size and wall access. Partial jobs (e.g., one bathroom) may finish in 1–2 days.
Q: Can I mix copper and PEX pipes?
A: Yes! Many modern systems use copper for main lines and PEX for branch lines to save costs. Use dielectric unions to prevent galvanic corrosion.
Q: Does homeowners insurance cover copper pipe replacement?
A: Usually only if damage is sudden and accidental (e.g., burst pipe). Wear-and-tear replacements are your responsibility.
Q: Are there health risks with copper pipes?
A: Minimal. The EPA states that copper levels from plumbing are generally safe. However, if your water is highly acidic (pH < 6.5), it may leach excess copper—test your water if concerned.
Q: What’s the biggest mistake homeowners make when installing copper plumbing?
A: Choosing the cheapest contractor without checking licenses or references. Poor soldering leads to pinhole leaks within 5–10 years.
Conclusion
So, how much does it cost to install copper plumbing? While the price tag—$3,000 to $12,000—may seem steep, you’re investing in a system that can last longer than your mortgage. Copper delivers clean water, boosts home value, and stands the test of time.
