Napa County
Repipe Specialists
Napa County stretches from the Napa River wetlands at San Pablo Bay through 30 miles of wine-country corridor to Calistoga at the head of the valley. The City of Napa is the population center and home to the most varied housing inventory in the county, while Calistoga, St. Helena, and Yountville each contain pre-1900 historic-district cores with original galvanized iron supply lines. American Canyon, the youngest incorporated city in the county, was built almost entirely after 1992 and has predominantly modern PEX and copper plumbing.
What unites the older Napa County cities is plumbing age. Most Napa, St. Helena, Calistoga, and Yountville homes were piped with galvanized steel between 1940 and 1980, and that pipe is now well past its 50- to 70-year service life. Calistoga homeowners face an additional concern: the city's exceptionally soft Kimball Reservoir water aggressively corrodes the lead-tin solder used in mid-century copper joints, producing the highest concentration of copper pinhole leaks in the county.
The signs are showing up everywhere — rust-colored water from the tap, low water pressure at multiple fixtures, recurring pinhole leaks, and the slow water-damage costs that follow. Repipe Champions has spent years repiping wine-country homes across every city and pipe era. Our crews are equally comfortable on a Napa Old Town Victorian crawl space, a Calistoga spa-area soft-water pinhole-leak retrofit, and an American Canyon slab-foundation tract home.
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.
Our Napa County line is (408) 295-4309. Free in-home estimates available throughout all five cities.

Napa 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 in Napa, St. Helena, Calistoga, and Yountville homes built before 1980.
Low Water Pressure
Mineral buildup inside aging pipes restricts flow over decades. If multiple fixtures have low pressure simultaneously, the pipe itself is usually the culprit.
Frequent Pinhole Leaks
Particularly common in Calistoga homes because of the city's soft Kimball Reservoir water. One pinhole leak is a warning. Two or more means systemic copper failure.
Banging or Noisy Pipes
Water hammer, rattling, or banging sounds in your walls can indicate aging pipe brackets, pressure irregularities, or deteriorating pipe sections.
Visible Corrosion
Green or white mineral deposits on exposed pipes under sinks or in crawl spaces indicate active corrosion and imminent failure risk.
