How Much Does Replumbing a House Cost? (2024 Guide)

If your home’s pipes are old, leaking, or made of outdated materials like galvanized steel or polybutylene, you might be facing a full replumbing job. It’s a big decision—and a big expense. Many homeowners ask, “How much does replumbing a house cost?” The answer isn’t simple, but this guide breaks it down clearly, so you can plan confidently and avoid costly surprises.

What Is House Replumbing—and When Do You Need It?

Replumbing a house means replacing some or all of the existing plumbing pipes, fixtures, and sometimes the main water line. It’s not just about fixing a leak—it’s a comprehensive upgrade to ensure your home’s water system is safe, efficient, and up to code.

Common signs you need replumbing:

• Frequent leaks or pipe bursts
• Low water pressure throughout the house
• Discolored or smelly water
• Pipes older than 50 years (especially galvanized steel or polybutylene)
• Rust or corrosion on visible pipes

According to the International Association of Certified Home Inspectors, homes built before 1970 are especially at risk for outdated plumbing systems that can lead to health hazards or water damage.

How Much Does Replumbing a House Cost in 2024?

The national average cost to replumb a house ranges from $4,000 to $15,000, but it can go as high as $20,000+ for large or complex homes. Several factors influence this wide range:

For example:

• A 1,500 sq ft home with easy access might cost $6,000–$9,000 using PEX.
• A 3,000 sq ft historic home with copper and finished walls could exceed $18,000.

💡 Pro Tip: PEX (cross-linked polyethylene) is now the most common choice for replumbing due to its flexibility, durability, and lower cost—approved by the International Plumbing Code .

Cost Breakdown by Pipe Material

Not all pipes are created equal. Your material choice affects both upfront cost and long-term reliability.

1. PEX Tubing

• Cost: $0.40–$2 per linear foot
• Pros: Freeze-resistant, easy to install, corrosion-proof
• Cons: Not UV-resistant (can’t be used outdoors exposed to sun)
• Best for: Most modern homes; ideal for DIY-assisted projects

2. Copper Pipes

• Cost: $2–$8 per linear foot (plus higher labor)
• Pros: Long lifespan (50+ years), recyclable, fire-resistant
• Cons: Expensive, prone to theft, can corrode in acidic water
• Best for: High-end renovations or areas with strict codes

3. CPVC (Chlorinated Polyvinyl Chloride)

• Cost: $0.50–$1.50 per foot
• Pros: Handles hot water well, cheaper than copper
• Cons: Brittle in cold temps, less flexible than PEX
• Best for: Budget-conscious hot water lines

⚠️ Avoid polybutylene (used 1978–1995)—it’s prone to failure and often requires full replacement.

Labor Costs: What to Expect

Labor typically makes up 60–70% of your total replumbing bill. Why? Because plumbers often need to:

1. Cut into drywall or flooring
2. Reroute pipes to meet modern code
3. Reinstall walls, tiles, or cabinetry afterward

Average labor rates:

• $45–$150/hour, depending on location and expertise
• $200–$500/day for small teams

📌 Real-World Example: In Austin, TX, a homeowner paid $11,200 to replumb a 2,200 sq ft ranch-style home using PEX. The job took 10 days, with 3 plumbers working 6 hours/day.

Hidden Costs to Watch For

Don’t get blindsided. These often-overlooked expenses can add 10–25% to your budget:

• Wall/floor restoration: $500–$3,000 (patching drywall, retiling)
• Permits: $100–$500 (required in most U.S. cities)
• Water heater or fixture upgrades: If old units aren’t compatible
• Emergency repairs: If hidden damage is found during demo

Always ask for a detailed line-item estimate—not just a lump sum.

DIY vs. Hiring a Pro: What’s Safer?

While PEX is DIY-friendly for small fixes, full-house replumbing should be left to licensed professionals. Why?

• Code compliance: Mistakes can fail inspection or void insurance
• Warranty: Pros offer 1–10 year workmanship guarantees
• Time: A DIYer might take weeks; a crew finishes in days

🛠️ Exception: If you’re experienced and only replumbing a single bathroom with accessible walls, DIY might save $1,000–$2,000—but verify local codes first.

How to Save Money on Replumbing

You don’t have to sacrifice quality to save. Try these strategies:

1. Get 3+ quotes – Prices can vary by 30% between contractors
2. Choose PEX over copper – Saves $3,000–$7,000 on average
3. Schedule off-season – Winter often has lower demand (and rates)
4. Bundle with other renovations – If you’re remodeling a kitchen, do plumbing at the same time to avoid double demo

Step-by-Step: What Happens During a Replumbing Job?

1. Inspection & planning (1–2 days): Plumber assesses layout, materials, and permits needed.
2. Shut off water & drain system (Day 1): Prevents flooding during work.
3. Remove old pipes (Days 2–4): Cut into walls/floors as needed.
4. Install new piping (Days 3–7): Run PEX/copper from main line to each fixture.
5. Pressure test (Day 7): Ensures no leaks before closing walls.
6. Restore surfaces (Days 8–10): Drywall, paint, tile reinstalled.
7. Final inspection (Day 10+): City inspector approves work.

Total time: 7–14 days for most homes.

FAQ: Your Top Questions Answered

Q: Does homeowners insurance cover replumbing?

A: Generally, no—unless sudden damage (like a burst pipe) caused the need. Routine upgrades or aging pipes are considered maintenance and aren’t covered.

Q: How long does replumbing last?

A: PEX lasts 40–50 years, copper 50–70+ years. With proper water chemistry, your new system should outlive you.

Q: Can I live in the house during replumbing?

A: Yes, but expect no running water for 2–5 days. Most contractors stage the work by zone (e.g., one bathroom at a time) to minimize disruption.

Q: Is PEX safe for drinking water?

A: Yes. PEX is NSF/ANSI 61-certified for potable water and used in millions of U.S. homes. It doesn’t leach harmful chemicals when installed correctly.

Q: How do I find a trustworthy plumber?

A: Check licenses (via your state contractor board), read Google/BBB reviews, and ask for proof of insurance. Avoid contractors demanding full payment upfront.

Q: Will replumbing increase my home’s value?

A: Indirectly, yes. Updated plumbing makes your home more attractive to buyers, avoids red flags during inspections, and prevents future repair liabilities.

Conclusion

Understanding how much does replumbing a house cost empowers you to make smart, stress-free decisions. While the investment is significant—typically $4,000 to $15,000—it protects your home, health, and wallet from costly emergencies down the road.
