If you’re asking, “How much will it cost to replumb my house?”, you’re likely dealing with aging pipes, recurring leaks, or planning a major home upgrade. Replumbing isn’t just a repair—it’s an investment in your home’s safety, efficiency, and value. And while the price tag can feel overwhelming, understanding what drives costs helps you make smarter decisions without surprises.
Why Do Homeowners Need to Replumb Their Houses?
Most homes built before the 1980s used galvanized steel or polybutylene pipes—materials now known for corrosion, leaks, or even health risks. According to the U.S. Environmental Protection Agency (EPA), outdated plumbing can reduce water pressure, increase utility bills, and contaminate drinking water.
Common signs you need a full replumb:
- Rust-colored or foul-smelling water
- Frequent pipe leaks or low water pressure
- Visible corrosion or greenish buildup on pipes
- Age of home: 50+ years old
Ignoring these issues can lead to costly water damage—the Insurance Information Institute reports that plumbing failures cause over $14 billion in property damage annually in the U.S.
How Much Will It Cost to Replumb My House in 2026?
The national average cost to replumb a house ranges from $4,000 to $15,000, according to HomeAdvisor’s 2026 data. However, your actual cost depends on several key factors:
| Factor | Impact on Cost |
|---|---|
| House Size | Small (1–2 beds): $3,500–$7,000 Medium (3 beds): $6,000–$10,000 Large (4+ beds): $10,000–$20,000+ |
| Pipe Material | PEX: $0.40–$2/ft Copper: $2–$8/ft CPVC: $0.50–$1.50/ft |
| Accessibility | Open walls = lower labor Finished walls = +20–50% cost |
| Location | Urban areas (e.g., NYC, SF) often cost 20–30% more than rural regions |
💡 Pro Tip: PEX (cross-linked polyethylene) is now the most popular choice for repiping—it’s flexible, freeze-resistant, and up to 60% cheaper than copper.
What Factors Influence Replumbing Costs?
1. Type of Pipes Used
- PEX: Affordable, easy to install, and durable. Ideal for most modern homes.
- Copper: Long-lasting and eco-friendly but expensive and labor-intensive.
- CPVC: Budget-friendly plastic option, but less flexible than PEX.
For reference, replacing 200 linear feet of pipe with copper could cost $1,600–$4,000, while PEX would run $200–$800 for the same distance.
2. Home Layout & Accessibility
Homes with basements or crawl spaces allow easier access, reducing labor time. If your walls are finished (drywall, tile, etc.), contractors must cut openings, patch, and repaint—adding $1,000–$3,000 to your bill.
3. Permits & Local Codes
Most cities require plumbing permits ($100–$500). Skipping this risks failed inspections or insurance denial. Always verify local building codes—some states restrict certain materials like polybutylene (now banned in many areas).
4. Emergency vs. Planned Repipe
Emergency fixes (e.g., burst pipes) cost 20–40% more due to after-hours labor and rushed work. Planning ahead saves money and stress.
Step-by-Step: What Happens During a Full House Repipe?
- Inspection & Estimate
A licensed plumber inspects your system using cameras or pressure tests. Expect a detailed quote within 24–48 hours. - Permit Application
Your contractor files for permits—this takes 3–10 business days depending on your municipality. - Shut Off Water & Remove Old Pipes
Water is turned off. Old pipes are cut out. Debris is removed daily to minimize mess. - Install New Pipes
New lines are run from the main supply to each fixture. PEX installations typically take 2–5 days for a 2,000 sq ft home. - Pressure Testing & Inspection
The system is tested at 80 PSI for 2+ hours to check for leaks. A city inspector then approves the work. - Wall Repair & Cleanup
Drywall patches, painting, and final cleanup complete the job.
⚠️ Note: Always hire a licensed, insured plumber. The National Association of Plumbing-Heating-Cooling Contractors (NAPHCC) recommends checking licenses via your state’s contractor board.
PEX vs. Copper: Which Is Right for You?
| Feature | PEX | Copper |
|---|---|---|
| Cost | Low | High |
| Installation Speed | Fast (fewer fittings) | Slow (soldering required) |
| Lifespan | 40–50 years | 50–70 years |
| Freeze Resistance | Excellent | Poor (can burst) |
| Eco-Friendliness | Recyclable but petroleum-based | Fully recyclable |
While copper has a longer lifespan, PEX dominates 80% of new repipe jobs today due to its cost-effectiveness and reliability. Learn more about piping materials on Wikipedia’s plumbing page.
How to Save Money on Replumbing
- Bundle with other renovations (e.g., kitchen remodel) to avoid duplicate wall openings.
- Get 3+ quotes—prices can vary by 30% between contractors.
- Ask about financing—many plumbers offer 0% APR for 12–24 months.
- Choose PEX over copper unless resale value in your area demands premium materials.
Avoid DIY replumbing. One mistake can cause flooding, mold, or code violations. The average insurance claim for DIY plumbing errors exceeds $12,000 (State Farm, 2025).
FAQ Section
Q1: How long does it take to replumb a house?
A: Most full-house repipes take 3 to 7 days. Smaller homes may finish in 2 days; larger or complex layouts can take up to 2 weeks.
Q2: Does homeowners insurance cover repiping?
A: Typically no—insurance covers sudden damage (like a burst pipe), not preventative upgrades. However, if polybutylene pipes fail and cause water damage, some policies may cover part of the replacement.
Q3: Can I live in my house during repiping?
A: Yes, but expect no running water for 1–3 days. Many families stay with relatives or book a short hotel stay for comfort.
Q4: Will replumbing increase my home’s value?
A: Yes! A full repipe can add 3–5% to your home’s market value, especially if replacing outdated or hazardous materials. Buyers prefer move-in-ready plumbing.
Q5: What’s the cheapest way to replumb?
A: Use PEX tubing, schedule during off-peak seasons (late fall/winter), and choose a reputable local contractor over big national chains.
Q6: How do I know if my house has polybutylene pipes?
A: Look for gray, blue, or black plastic pipes near your water heater or main shut-off valve. They were commonly installed between 1978 and 1995 and are prone to cracking.
Conclusion
Understanding how much will it cost to replumb my house empowers you to protect your biggest investment—your home. While upfront costs range from $4,000 to $15,000+, the long-term benefits include lower water bills, fewer repairs, better water quality, and higher resale value.
