Whole-House Repiping in San Francisco, CA
The repipe conversation in San Francisco starts with the era: homes built before 1940 carry original galvanized-steel supply lines, and when leaks or brown water arrive, section repairs become whack-a-mole. The real differentiator between bids is drywall repair scope — compare that, not just totals.
Statewide, whole-house repiping typically runs $4,500–$15,000. In San Francisco, licensed plumbers bill $150–$250 per hour with service-call fees of $90–$150 — flat-rate pricing is common for standard jobs, and the fee is usually credited when you approve the work. For the state-wide view, see the Whole-House Repiping cost guide.
What San Francisco's homes mean for whole-house repiping
For leak and pipe work, read San Francisco by its building permits: homes with nearly half its homes built before 1940 mean original galvanized-steel supply lines, and raised foundations with crawl spaces set the access rules. Local plumbers price repairs against both facts before the first wall opens.
- Raised foundations in the older neighborhoods mean a technician can usually get under the house — repairs that would mean jackhammering a slab elsewhere are crawl-space work here.
- Homes from San Francisco's early build-out still carry original galvanized supply pipe in places — it corrodes shut from the inside, and brown water or weak flow at multiple fixtures is the classic tell.
- In San Francisco's condos, the wall is the border: HOAs typically own pipes inside common walls while you own what serves only your unit — check your CC&Rs before authorizing work, and loop the HOA in early.

How do I find out what pipes my San Francisco house has?
Look where pipe is exposed: at the water heater, under sinks, in the garage or crawl space. Given San Francisco's stock (Victorians, Edwardians and Marina-style flats shoulder to shoulder, plus modern condo towers), the likely finding is original galvanized-steel supply lines. Dull gray threaded steel is galvanized — magnetic, unlike copper — and it is the material worth replacing.
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.
