Repiping replaces every water supply line in the house — the definitive fix for repeated pinhole leaks, slab leaks in series, dying galvanized pipe or low pressure. In California, a typical single-family repipe runs $4,500–$15,000+ depending on size, material and wall repair.

PEX repipes price at the lower half of the range and dominate the market: flexible tubing means fewer wall openings and one- to three-day jobs. Copper costs 30–60% more in materials and labor but remains the premium choice. Either way the real differentiator between bids is drywall patching and texture-matching — some quotes include full repair and paint-ready walls, others leave you with dozens of open holes. Compare scope, not just totals.

A repipe requires a permit and inspection in California, and it is the moment to add a proper pressure regulator and main shutoff. Homes in the state of California built before the 1970s with original galvanized pipe are the classic candidates — brown water and weak flow are the tell.

Frequently asked questions

How much does repiping cost in California?

For a typical single-family home in the state of California: $4,500–$9,000 in PEX, $8,000–$15,000+ in copper — bathroom count, stories and drywall repair scope drive the spread. Get at least three itemized bids.

PEX or copper — which is better?

PEX: cheaper, faster, quieter, immune to the pinhole corrosion eating copper in some water districts; it must be kept out of UV light. Copper: proven for 70+ years, rodent-proof, slightly higher resale perception. Most California repipes today are PEX — both are code-approved.

How long does a repipe take — and can I live at home?

Most single-family repipes take 1–3 days of pipe work plus a few days of drywall repair. Water is typically only off during working hours; most families stay home throughout.
