Marin County
Repipe Specialists
Marin County is one of California's smallest counties by area but one of its most expensive per square foot, with a residential housing inventory that spans 160 years — from 1860s Sausalito waterfront Victorians to 2000s Hamilton AFB redevelopment in Novato. The eleven incorporated cities sit alongside significant unincorporated areas (Kentfield, Greenbrae, Strawberry, Marinwood) plus the West Marin towns of Bolinas, Stinson Beach, Point Reyes Station, Inverness, and Woodacre. What unites Marin's housing stock is plumbing age: most homes built before 1980 were piped with galvanized steel water lines that are now well past their 50- to 70-year service life.
The Marin Municipal Water District serves most of the county; North Marin Water District serves Novato. Marin's relatively soft water chemistry interacts predictably with aging galvanized and thinner-wall copper, producing the characteristic rust-colored water, low pressure, and pinhole leaks that signal end-of-life pipe across San Rafael Terra Linda, Mill Valley Tamalpais Valley, central Novato, and similar mid-century tracts. Coastal homes in Belvedere, Tiburon, and Sausalito waterfront have additional considerations from salt-air corrosion on exterior pipe and meter assemblies. Septic-to-sewer conversions are still happening across West Marin, which often coincides with whole-house repipe planning.
Repipe Champions has spent years repiping Marin homes across every city and pipe era. Our crews are equally comfortable on a Sausalito Victorian crawl space lateral, a Novato Hamilton slab-foundation 2000s home, and a Ross estate with century-old period millwork that requires preservation-compliant routing. We replace failing galvanized steel and aging copper systems with either Uponor PEX-A, the highest-rated flexible pipe system on the market, or L-grade American copper, depending on your preference and budget. Both come backed by our 25-year PEX or 30-year copper parts and labor warranty.

Marin County homes built before 1980 are especially prone to these warning signs. Don't wait for a burst pipe — catch it early.
Rust-Colored Water
Brown or orange-tinted water from your taps is a classic sign of corroding galvanized steel pipes. Common across pre-1980 San Rafael, Novato, Mill Valley, and Larkspur tracts.
Low Water Pressure
Mineral buildup inside aging pipes restricts flow over decades. If multiple fixtures have low pressure simultaneously across your Marin home, the pipe itself is usually the culprit.
Frequent Pinhole Leaks
Particularly common on coastal-edge thin-wall copper in Belvedere, Tiburon, and Sausalito waterfront. Two or more pinholes means systemic failure — patching won't solve it.
Banging or Noisy Pipes
Water hammer, rattling, or banging sounds in your walls can indicate aging pipe brackets, pressure irregularities, or deteriorating pipe sections in older Marin homes.
Visible Corrosion
Green or white mineral deposits on exposed pipes under sinks or in crawl spaces — common in Mill Valley, Fairfax, and Ross hillside crawlspaces — indicate active corrosion and imminent failure risk.
Home Built Before 1980
If your Marin County home was built between 1860 and 1980 and has never been repiped, it's time for a free inspection — even if symptoms are not yet obvious.
