How Much Does Copper Repiping Cost?
Copper repiping is significantly more expensive. Most copper repipe projects range from $8,000 to $20,000, depending on home size and layout. Copper pipe material costs $2 to $4 per foot, and installation requires extensive wall access and soldered connections.
Copper is durable but prone to corrosion, pinhole leaks, and mineral buildup over time, which increases long-term maintenance costs.

- PEX requires less labor and fewer fittings
- Copper installation takes longer and involves more demolition
- PEX resists corrosion and mineral buildup

What Factors Increase Repiping Costs?
- Number of plumbing fixtures

- Accessibility of existing pipes
- Slab foundation or concrete walls
- Permit and inspection requirements

Why Repiping Costs More Than Spot Repairs
Repeated pipe repairs often cost more over time than a full repipe. Older systems commonly develop multiple leaks, leading to ongoing service calls, water damage, and higher labor costs. Repiping replaces the entire system at once, eliminating future failures and providing long-term stability.

Is Repiping Covered by Insurance?
Most insurance policies do not cover repiping itself because it is considered a maintenance upgrade. However, insurance may cover resulting water damage caused by sudden pipe failures. Coverage depends on policy terms and the cause of the leak.
