As a licensed contractor with 15 years of plumbing experience, I’ve overseen hundreds of repiping projects. This guide provides the exact costs you can expect in 2024, helping you make an informed decision between PEX and copper systems.
What Is Whole House Repiping?
Whole house repiping involves completely replacing all water supply lines in your home, from the main water line to every fixture. This major plumbing renovation typically takes 3-7 days and requires opening walls to access existing pipes.
Repiping becomes necessary when:
- Pipes are 25+ years old (galvanized steel or old copper)
- You experience frequent leaks or low water pressure
- Water quality issues persist despite filtration
- Planning major renovations that require plumbing updates
Pro Tip: Repiping during kitchen or bathroom renovations can save 15-25% on total costs since walls are already open for other work.

Signs You Need Whole House Repiping
Immediate Red Flags
• Discolored water - Brown, yellow, or rust-colored water indicates pipe corrosion • Multiple leaks per year - More than 2-3 leaks annually suggests systemic failure • Low water pressure - Consistent pressure below 40 PSI throughout the house • Metallic taste - Indicates copper or iron leaching from deteriorating pipes • Visible corrosion - Green or white buildup on exposed copper pipes
Age-Based Indicators
• Galvanized steel pipes (1950s-1980s): Replace immediately if 40+ years old • Original copper (1960s-1990s): Consider replacement at 50+ years • Early PEX (1990s): Inspect for recalls and UV damage
Performance Issues
• Temperature fluctuations - Inconsistent hot water delivery • Strange noises - Banging, whistling, or gurgling sounds • High water bills - Hidden leaks increase usage costs • Frequent plumber visits - Ongoing repairs indicate system failure
Expert Insight: I recommend repiping when repair costs exceed 30% of replacement costs over a 2-year period. This “30% rule” helps homeowners avoid throwing good money after bad.

Frequently Asked Questions
How long does whole house repiping take?
Most repiping projects take 3-7 days depending on house size and complexity. PEX installations are typically 1-2 days faster than copper due to easier installation. Expect additional time for wall repairs and painting.
Can I live in my house during repiping?
Yes, but with limitations. You’ll have intermittent water service during active work hours. Most contractors provide temporary connections for essential fixtures. Plan alternative arrangements for cooking and bathing during the 2-3 peak work days.
Will repiping increase my home value?
Repiping typically increases home value by $3,000-$8,000, representing a 50-70% return on investment. Copper systems may provide slightly higher value perception, but PEX systems offer better cost-benefit ratios.
Do I need permits for whole house repiping?
Yes, permits are required in 99% of municipalities for whole house repiping. Costs range from $50-$300 depending on location. Professional contractors handle permit applications and coordinate required inspections.
How do I know if my current pipes are failing?
Key warning signs include frequent leaks, discolored water, low pressure, and pipes over 25 years old. If you’re experiencing multiple issues simultaneously, full replacement often costs less than ongoing repairs.
Should I choose PEX-A or PEX-B for my home?
PEX-A (cross-linked polyethylene) offers superior flexibility and fewer fittings, making it ideal for whole house applications despite the 15-20% cost premium. PEX-B works well for smaller projects but requires more joints and fittings.
What warranty should I expect on repiping work?
Labor warranty: Minimum 2 years, premium contractors offer 5+ years Material warranty: PEX manufacturers provide 25+ year warranties, copper offers 50+ years Always get warranties in writing with specific coverage details.
Final Thoughts: Making Your Repiping Decision
Choosing between PEX and copper for whole house repiping ultimately depends on your budget, long-term plans, and personal preferences. PEX offers immediate savings and excellent performance for most homes, while copper provides maximum longevity and traditional reliability.
Choose PEX if you:
- Want to minimize upfront investment
- Live in freeze-prone climates
- Plan to sell within 15-20 years
- Prefer faster project completion
Choose copper if you:
- Plan to stay long-term (20+ years)
- Want maximum resale value
- Live in high-temperature climates
- Prefer traditional, proven materials
Both materials will provide decades of reliable service when properly installed by qualified professionals. The key is working with experienced contractors who understand local codes and installation best practices.
