Why San Francisco Homes Need Repiping
The majority of San Francisco's single-family homes were built between 1900 and 1960 with galvanized steel water supply pipes. After 60-100+ years, these pipes are corroded internally — reducing effective diameter by 50-70% and contaminating water with rust particles. Low water pressure, discolored water, and pinhole leaks are daily reality for thousands of SF homeowners.
Unlike newer Peninsula cities where repiping is straightforward, San Francisco homes present unique routing challenges: multi-story construction with balloon framing, plaster-and-lath walls, shared walls in row houses, and limited crawlspace access. Successful repiping in SF requires experienced planning to minimize wall openings while achieving complete pipe replacement.

San Francisco Repiping Challenges We Solve
Victorian Wall Routing
San Francisco's balloon-frame Victorians have continuous wall cavities from basement to attic — useful for routing new pipes, but only if you know how to navigate fire-blocking, cross-bracing, and existing wiring without destroying historic fabric.
Row House Shared Walls
In the Sunset, Richmond, and Excelsior, row houses share party walls with zero space between. All piping must route through interior walls or the limited exterior — requiring creative solutions that other cities' plumbers rarely encounter.
Multi-Story Pressure Design
Three-story SF homes (common in Noe Valley and the Mission) need properly sized supply risers and pressure management to deliver consistent flow to upper-floor bathrooms — something galvanized pipes can no longer provide.
Our San Francisco Repiping Process
In-Home Survey & Route Planning
We map every fixture, assess wall construction, and plan the most efficient routing to minimize openings in your plaster walls and hardwood floors.
Material Selection & Sizing
We recommend copper or PEX based on your home's specific needs, budget, and layout. Pipe sizing is calculated for proper pressure at every fixture.
Installation (3-5 Days)
New pipes installed through planned access points. Water is typically off for only a few hours per day. We protect floors, walls, and furnishings throughout.
Testing, Patching & Inspection
Full pressure test, leak check at every connection, wall patching, and city inspection. You'll have strong, clean water at every faucet.
