Repiping in California
Repiping across California: the 1,921 ZIP codes and 726 cities we route calls in, and who licenses plumbers in the state.

Free to homeowners in California — the contractor pays us for the introduction, you never do.
Whole house or one run
Our repiping coverage in California runs to 1,921 ZIP codes in 726 cities. In large municipalities a repipe is as much a question of access as of pipe: what is behind the wall, what the building rules require to be opened, and whether the work can be done from the basement or has to come through finished rooms.

What this site is
PipeRenew is a referral service, not a contractor. We connect homeowners with independent contractors. Contractors are required to hold whatever credential their state or municipality demands, and replacing a water distribution system is a permitted alteration nearly everywhere — ask to see the permit. We carry out no work, we sell no materials, we do not set prices, and we never charge homeowners anything — the contractors in our network pay us when we route them a call. Nothing here is legal advice about any claim.Checking a credential in California
California licenses are issued by the Contractors State License Board, which publishes a public search you can use before work begins. California licenses the C-36 plumbing contractor; there is no state journeyman license.

What that coverage looks like
California coverage runs to 1,921 ZIP codes across 40 counties, Los Angeles County contributing 494. A repipe is a multi-day job and the scheduling is not like a leak call; across a footprint this size it is worth getting the quote and the scope settled well before the pipe forces the issue.
How a repiping job goes
Repiping is decided by material and failure mode, not by age. Galvanized steel closes up from the inside and shows as falling pressure; polybutylene fails at the fittings; copper pinholes where the water is aggressive. Each points at a different scope of work, and a house with one bad run does not necessarily need the whole supply replaced.
What the call asks about repiping
- What the existing pipe is made of — galvanized steel, copper, polybutylene or plastic.
- Whether the trouble is pressure, color, pinhole leaks, or all three.
- Whether the house has a basement or crawl space the run can be reached from.
Every California city we route in
397 cities, ordered by the share of homes built between 1970 and 1999. Whole-house repiping is a question of when the house was built, not of how big the town is. Each page carries that city’s own numbers and the ZIP codes we route there.

Before you call
Repiping is decided by what the existing pipe is made of and how it is failing, not by its age alone. The pages above set out the difference.
