When the third leak hits the same San Mateo house, the math flips: section repairs stop being maintenance and start being installments on a repipe. Homes built across many decades carrying everything from prewar galvanized steel to brand-new PEX, block by block are the classic candidates — and the permit plus inspection protect the investment at resale.
Plan around $4,500–$15,000 for most whole-house repiping work statewide. Local labor is the multiplier — San Mateo crews bill $150–$250 an hour, plus $90–$150 per service call — so identical jobs can price far apart between regions. Itemized local bids are the only numbers that count. For the state-wide view, see the Whole-House Repiping cost guide.
The local picture in San Mateo
Pipe age is destiny in San Mateo: prewar and early-postwar neighborhoods under mature trees, plus newer bayfront condos, carrying everything from prewar galvanized steel to brand-new PEX, block by block, over raised foundations in the older neighborhoods, slab in the newer ones. That combination decides everything from where leaks appear to whether a reroute beats opening concrete.
- The crawl spaces under San Mateo's older homes are a plumbing blessing: supply, drain and gas lines stay reachable without opening concrete, which keeps repair bills down.
- Galvanized-era plumbing survives in San Mateo's older housing; once it starts restricting flow, section fixes buy time but a repipe is the honest endgame.
- Condo plumbing in San Mateo means shared risers and HOA boundaries; a leak's location decides who pays, so document everything and notify the association before repairs start.
Price factors to expect
- Drywall repair scope included or not
- Permit + inspection
- Two-story and slab homes cost more
- Access: crawl spaces under San Mateo's older homes keep labor down

What pipe material do San Mateo homes have?
Most of the stock here was built across many decades, which means everything from prewar galvanized steel to brand-new PEX, block by block. Original galvanized lines from that era are at or past end of life; weak flow and discolored water are the classic signs.
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.
