If you’ve noticed low water pressure, discolored water, or mysterious leaks, it might be time to replace your home’s pipes. But before you call a plumber, you’re probably wondering: how much does a plumber charge to replace pipes? The answer isn’t one-size-fits-all—it depends on materials, labor, home size, and more. In this guide, we’ll break down everything you need to know to budget wisely and avoid costly surprises.
What’s the Average Cost to Replace Pipes in a House?
According to HomeAdvisor and Angi (formerly Angie’s List), the national average cost to replace pipes in a home ranges from $2,000 to $15,000 in 2024. However, full repiping projects can climb as high as $20,000+ for large homes or complex systems.
Here’s a quick breakdown by scope:
| Partial pipe replacement (1–2 fixtures) | $500 – $2,500 |
| Repiping a single bathroom | $1,500 – $4,000 |
| Whole-house repipe (1,500 sq ft home) | $4,000 – $15,000 |
| Copper vs. PEX repipe (full house) | $8,000 – $20,000 |
💡 Pro Tip: Labor typically accounts for 60–70% of your total cost—more than materials.
What Factors Affect Pipe Replacement Costs?
Several variables influence your final bill. Understanding them helps you negotiate fairly and plan ahead.
1. Type of Pipes Being Installed
- PEX (cross-linked polyethylene): $0.40–$2.00 per linear foot. Flexible, freeze-resistant, and easy to install.
- Copper: $2.50–$8.00 per linear foot. Durable and long-lasting but expensive and labor-intensive.
- CPVC (chlorinated polyvinyl chloride): $0.50–$2.00 per foot. Good for hot water, but less flexible than PEX.
- Galvanized steel (outdated): Rarely used today due to corrosion risks—replacing it is often urgent.
According to the U.S. Environmental Protection Agency , outdated galvanized pipes can leach lead and reduce water quality—making replacement a health priority.
2. Home Size and Layout
Larger homes = more piping. A 2,500 sq ft house may need 200–400 linear feet of pipe per floor. Multi-story homes increase labor time due to access challenges.
3. Accessibility
If pipes run behind finished walls, ceilings, or under slabs, plumbers must cut into drywall or flooring. Wall restoration alone can add $1,000–$3,000 to your project.
4. Permits and Local Codes
Most municipalities require permits for full repiping. Fees range from $100 to $500, but skipping them risks fines or failed inspections.
5. Emergency vs. Scheduled Service
Emergency calls (e.g., burst pipes at 2 a.m.) can cost 1.5x to 3x standard rates. Schedule during business hours if possible.
PEX vs. Copper: Which Is Better—and Cheaper?
Many homeowners face this dilemma. Let’s compare:
| Cost (materials) | Low | High |
| Installation time | Faster (fewer fittings) | Slower (soldering required) |
| Lifespan | 40–50 years | 50–70+ years |
| Freeze resistance | Excellent | Poor (can burst) |
| Eco-friendliness | Recyclable but petroleum-based | Fully recyclable |
📌 Expert Insight: “For most residential repiping jobs today, PEX is the go-to,” says Marcus Lee, Master Plumber with 18 years of experience in Chicago. “It’s cost-effective, reliable, and handles temperature swings better than copper.”
Step-by-Step: What to Expect During a Pipe Replacement
- Inspection & Quote (Day 1)
A licensed plumber inspects your system using cameras or pressure tests. They’ll provide a written estimate within 24–48 hours. - Permit Application (If Required)
Your plumber usually handles this. Allow 3–7 business days for approval. - Shut Off Water & Prepare Work Area
Water is turned off. Furniture is moved, and drop cloths protect floors. - Remove Old Pipes
Sections of drywall or flooring may be cut (typically 12”–24” access panels). - Install New Pipes
For PEX: crimp or clamp fittings are used. For copper: joints are soldered at 650–750°F. - Pressure Test & Inspection
System is pressurized to 80 PSI for 15–30 minutes to check for leaks. - Restore Walls & Clean Up
Drywall is patched, painted, and debris removed. Most jobs take 2–5 days for a full house.
How to Save Money on Pipe Replacement
- Get 3+ Quotes: Prices vary widely. Compare itemized estimates.
- Choose PEX Over Copper: Save 30–50% on materials and labor.
- Bundle with Other Renos: If remodeling a kitchen or bathroom, do plumbing at the same time to avoid duplicate wall cuts.
- Ask About Warranties: Reputable plumbers offer 10–25 year warranties on materials and workmanship.
- Check for Rebates: Some municipalities offer incentives for upgrading to water-efficient systems.
⚠️ Warning: Avoid “too-good-to-be-true” quotes under $2,000 for whole-house repiping—they often cut corners or use subpar materials.
FAQ Section
Q: How long does it take to replace all the pipes in a house?
A: Most full repiping projects take 2 to 5 days for a standard 1,500–2,500 sq ft home. Larger or older homes with complex layouts may take up to 2 weeks.
Q: Can I replace my own pipes to save money?

Q: Does homeowners insurance cover pipe replacement?
A: Typically, no—unless damage is sudden and accidental (e.g., a burst pipe). Gradual wear, corrosion, or outdated materials are considered maintenance and aren’t covered.
Q: How do I know if my pipes need replacing?
A: Watch for: frequent leaks, rusty or discolored water, low water pressure, strange tastes/odors, or if your home was built before 1970 (likely has galvanized steel or polybutylene pipes).
Q: Is PEX safe for drinking water?
A: Yes. PEX is certified by NSF International and meets U.S. safety standards for potable water. It’s been used in Europe since the 1970s and in the U.S. since the 1980s.
Q: What’s the cheapest way to replace pipes?
A: Opt for PEX tubing, schedule during off-peak seasons (late fall/winter), and get multiple quotes. Avoid emergency service unless absolutely necessary.
