If your home’s pipes are leaking, corroded, or just plain outdated, you’re probably wondering: how much does it cost to have plumbing redone? Whether you’re dealing with frequent clogs, low water pressure, or planning a major renovation, understanding the real cost of repiping can save you time, stress—and thousands of dollars. In this guide, we’ll break down everything you need to know, from average prices to hidden factors that affect your final bill.
What Does “Having Plumbing Redone” Actually Mean?
“Having plumbing redone” typically refers to repiping—replacing old or damaged water supply lines throughout your home. This isn’t just fixing a leaky faucet; it’s a full-system overhaul that may involve removing walls, replacing copper or galvanized steel pipes with modern PEX or CPVC, and updating fixtures for better efficiency and safety.
According to the U.S. Department of Housing and Urban Development (HUD), homes built before 1970 are especially prone to outdated plumbing materials that can lead to health risks (like lead leaching) or structural damage from leaks. Repiping isn’t just a luxury—it’s often a necessity for safety and home value.
Average Cost to Repipe a House in 2025
The national average cost to have plumbing redone in the U.S. ranges from $4,000 to $15,000, depending on several key factors:
| Small (1–2 bedrooms) | $4,000 – $7,000 |
| Medium (3 bedrooms) | $6,000 – $10,000 |
| Large (4+ bedrooms) | $8,000 – $15,000+ |

These figures include labor, materials, permits, and minor drywall repairs. However, costs can spike if your home has hard-to-reach pipes, asbestos insulation, or requires extensive wall restoration.
Key Factors That Affect Repiping Costs
1. Type of Pipes Used
- PEX (Cross-linked Polyethylene): $0.40–$2.00 per linear foot. Flexible, freeze-resistant, and easy to install. Most popular choice in 2025.
- Copper: $2.50–$5.00 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 lines but less flexible than PEX.
- Galvanized Steel (to be replaced): Often found in homes built before 1960. Prone to rust and reduced water flow.
💡 Pro Tip: PEX is now the go-to for most contractors due to its affordability, durability, and ease of installation—especially in retrofitting older homes.
2. Home Size and Layout
Larger homes need more piping. Multi-story houses or those with complex layouts (e.g., split levels) increase labor time and access difficulty.
3. Accessibility of Pipes
If pipes run through finished walls, ceilings, or under slabs, contractors must cut openings, which adds to labor and drywall repair costs. Homes with basements or crawl spaces are easier (and cheaper) to repipe.
4. Permits and Local Labor Rates
Permit fees vary by city—typically $100–$500. Labor rates range from $45 to $150/hour, with higher costs in urban areas like New York, San Francisco, or Boston.
5. Extent of Work
- Partial repipe (e.g., kitchen + bathrooms only): $2,000–$6,000
- Full repipe (entire house): $6,000–$15,000+
- Emergency repipe (due to burst pipes or contamination): Can cost 20–30% more due to urgency.

Step-by-Step: What to Expect During a Repipe
- Inspection & Estimate
A licensed plumber inspects your system using cameras or pressure tests. They’ll provide a detailed quote within 24–48 hours. - Permit Application
Your contractor (or you) applies for a plumbing permit. Most states require this for full repiping. - Shut Off Water & Prepare Home
Water is turned off. Furniture is moved, and drop cloths protect floors. Temporary water access (e.g., outdoor hose) may be arranged. - Remove Old Pipes
Walls are carefully opened. Old pipes are cut out. Hazardous materials (like lead or asbestos) are handled per EPA guidelines. - Install New Pipes
New PEX or copper lines are run. Manifolds may be installed for better water pressure control. - Pressure Testing
The system is tested at 80–100 PSI for 15–30 minutes to ensure no leaks. - Inspection & Wall Repair
A city inspector approves the work. Drywall is patched, sanded, and primed (painting often extra). - Restore Water & Final Walkthrough
Water is turned back on. All fixtures are tested. You receive a warranty (typically 10–25 years on materials).
⏱️ Timeline: Most full repipes take 2–5 days for a standard home.
PEX vs. Copper: Which Is Right for You?
| Cost | Lower | Higher |
| Installation Time | Faster (no soldering) | Slower (requires skilled soldering) |
| Lifespan | 40–50 years | 50–70+ years |
| Freeze Resistance | Excellent | Poor (can burst) |
| Environmental Impact | Recyclable but petroleum-based | Highly recyclable, natural material |
| Best For | Retrofits, cold climates, budget projects | High-end builds, areas with rodent issues |
While copper has a longer track record, PEX dominates modern repiping due to its cost-effectiveness and resilience—especially in regions with harsh winters.
Signs You Need to Repipe (Don’t Wait for a Flood!)
- Rusty or discolored water
- Frequent leaks or pipe corrosion
- Low water pressure in multiple fixtures
- Strange odors from taps
- Age: Home built before 1970 with original plumbing
- Spiking water bills with no usage change
Ignoring these signs can lead to mold growth, structural damage, or even insurance claim denials.
How to Save Money on Repiping
- Get 3+ quotes from licensed, insured plumbers.
- Bundle with other renovations (e.g., kitchen remodel) to share wall-access costs.
- Choose PEX over copper unless local codes require otherwise.
- Ask about off-season discounts (winter months often have lower demand).
- Check if your homeowner’s insurance covers emergency pipe damage (rare for wear-and-tear, but possible for sudden failures).
FAQ Section
Q: How long does repiping last?
A: PEX lasts 40–50 years; copper can last 70+ years with proper maintenance. Both far outlast old galvanized steel (20–50 years, but often fails earlier due to rust).
Q: Can I repipe my house myself?
A: Technically yes, but not recommended. Repiping requires permits, pressure testing, and code compliance. DIY mistakes can cause leaks, failed inspections, or voided home warranties. Always hire a licensed plumber.
Q: Does homeowners insurance cover repiping?
A: Generally no—insurance covers sudden damage (like a burst pipe), not preventive upgrades. However, if outdated pipes cause a covered loss (e.g., fire from corroded lines), partial reimbursement may apply.
Q: Will repiping increase my home’s value?
A: Yes—especially if you’re selling. Updated plumbing is a major selling point. Buyers avoid homes with known pipe issues, and appraisers factor modern systems into valuation.
Q: How disruptive is repiping?
A: Moderately. Expect noise, dust, and temporary loss of water for 2–5 days. Most families stay home, but some opt for short-term lodging if multiple bathrooms are affected.
Q: What’s the cheapest way to repipe?
A: Use PEX tubing, limit wall openings by routing through attics or basements, and schedule work during contractor off-peak seasons (late fall or winter).
Conclusion
Knowing how much it costs to have plumbing redone empowers you to make smart, confident decisions about your home’s health and value. While the upfront investment may seem steep, a full repipe prevents costly emergencies, improves water quality, and boosts resale appeal.
If you’re considering repiping, get multiple quotes, verify contractor licenses, and don’t delay if you spot warning signs. Your future self—and your wallet—will thank you.
