Short answer
Spot repairs make sense for an isolated failure in otherwise sound pipe. Repiping is usually the better value when a home still has original galvanized steel, has had several leaks, shows rusty water or low pressure throughout, or has pinhole leaks appearing in different places in old copper.

Signs your pipes are near the end
Many homes built in the 1940s through 1960s still have original galvanized steel or early copper.
- Brown or rusty water, especially after the water sits
- Low pressure at several fixtures
- Pinhole leaks showing up in different places
- Visible corrosion at joints and galvanized-to-copper transitions
- Repeated repairs in the last few years
Copper or PEX for a repipe
Both are widely used in California. PEX is flexible and usually faster to install through existing walls, with fewer joints. Copper is rigid, long-proven and resists UV. Your plumber should explain the trade-offs for your house, budget and local code.

Call NowWhat a repipe involves
New supply lines are run to every fixture, usually through walls and attic with small access openings, then the old lines are disconnected. Most single-family repipes take a few days, with water off only part of each day. Drywall patching and paint follow.

Do I need a permit to repipe?
Repiping generally requires a permit and inspection through your city. The plumbing contractor normally pulls it.
Can I repipe only part of the house?
Yes, partial repipes are common, but leaving old sections means those can still fail. Ask the plumber to show you the condition of what stays.
How do I check a plumber's license in California?
Plumbing contractor licenses (C-36) are issued by the Contractors State License Board; you can look up the license number on the CSLB website.
