Key Takeaways
- Full repipe (1,500 sq ft home): typically $5,000–$10,000
- PEX repiping costs 25–35% less than copper
- Most repipes take 2–5 days and require patching drywall afterward
- Galvanized steel, polybutylene, and lead pipes are the most urgent candidates for replacement

PEX vs Copper: Cost Comparison for Repiping
PEX (cross-linked polyethylene) has become the dominant material for home repiping:
According to the Bureau of Labor Statistics, there are approximately 480,600 plumbers employed in the United States with a median annual wage of $61,550. The U.S. EPA reports that household water leaks can waste nearly 10,000 gallons per year.
| Factor | PEX | Copper |
|---|---|---|
| Material cost (per linear ft) | $0.40–$0.60 | $2.00–$5.00 |
| Installation speed | Faster (flexible, fewer joints) | Slower (rigid, more connections) |
| Freeze resistance | Better (expands and contracts) | More vulnerable to freeze damage |
| Expected lifespan | 40–50+ years | 50–70+ years |
| Overall project cost | Lower by 25–35% | Higher |
For most homeowners today, PEX provides excellent longevity at lower cost. Full comparison: PEX vs Copper Piping.
When Is Full Repiping Necessary?
- Galvanized steel pipes over 40–50 years old — corroding, reducing flow, leaching rust
- Polybutylene pipes — high failure rate; class action settlements recommend proactive replacement
- Lead pipes — health hazard; replace immediately per EPA guidelines
- Multiple leaks in different locations throughout the home
- Significantly reduced water pressure throughout (not a localized issue)
- Rust-colored water from multiple fixtures

A full repipe typically takes 2–5 days depending on home size:
- Day 1: Cut access points in drywall, remove old pipes, install new supply lines
- Day 2–3: Continue installation, connect to all fixtures and appliances
- Day 3–4: Inspection, pressure testing, reconnect water supply
- Day 4–5: Drywall patching (often a separate contractor)
You'll typically be without water for 1–2 days during the main installation phase. Most plumbing companies provide temporary accommodations or work in sections to minimize disruption.
Additional Costs to Budget For
- Drywall repair and painting: $500–$3,000 depending on scope of wall cuts
- Permit: $200–$500 (required; your plumber should obtain it)
- Water heater upgrade: Common to replace while pipes are open if unit is old
- Fixture replacements: If valves or faucets are corroded, budget $100–$500 for replacements
Frequently Asked Questions
Most homes take 2–4 days for the plumbing work itself. Add 1–2 days for drywall patching and 1–2 more days for painting if needed. The full project is typically complete within one week.
Yes — repiping is considered a significant home improvement. A new-pipe home is more attractive to buyers and eliminates a major concern during inspection. Industry estimates suggest repiping adds $5,000–$20,000 in value depending on the local market and the age of what was replaced.
Usually yes, but expect disruption. Water is typically shut off for 6–8 hours per day during active work. You'll need to plan around that. Bathrooms may be temporarily out of service while work is completed in each area.
Standard homeowners insurance does not cover repiping as a maintenance upgrade. However, if pipe failure causes water damage, that damage (not the repiping cost) may be covered. If you have galvanized or polybutylene pipes, check if your insurer has exclusions or rate increases — some do.
