Cotati
Repipe Specialists

Cotati is a tiny college-adjacent town of 7,500 residents directly south of Rohnert Park, notable for its rare hexagonal historic Plaza laid out in 1893 — one of only two six-sided town plazas in the United States. Its residential water-supply inventory is concentrated in the 1950s–2000s with a small original hexagonal townsite at its core. Old Town and the blocks immediately surrounding Cotati Plaza contain pre-1940 homes with original galvanized iron. The mid-century expansion along Page Street, East Cotati Avenue, and Henry Avenue produced 1950s–70s galvanized and first-gen copper now in the pinhole-leak window. The 1990s–2000s added Liman Way and Stage Coach Glen with copper and PEX. Cotati's high concentration of Sonoma State University rental housing in older blocks means many supply lines have seen heavy multi-occupant use. Cotati water comes from Sonoma Water — moderate hardness. The City of Cotati Planning Department administers all permits and Repipe Champions handles those filings on your behalf.

Repipe Champions specializes exclusively in repiping; it's all we do. That means we're faster, more efficient, and more affordable than a traditional plumber who does a little bit of everything. We serve every Cotati zip code and neighborhood, from 95110 in downtown to 95148 in East Cotati, with same-day estimates and next-day scheduling available.

Our team replaces failing galvanized iron, 1960s–80s copper, and modern PEX 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.

Repipe Champions only does repipes, so the crew is not fitting the job between drain calls. The visit is where the price is written down.

Does Your Cotati Home Need a Repipe?

Cotati homes built before 1975 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. This is common in Cotati homes built before 1970.

📉

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

One pinhole leak is a warning. Two or more means your pipes have reached systemic failure: patching won't solve the underlying corrosion problem.

🔊

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.

🏠

Home Built Before 1975

If your Cotati home was built in the 1950s–70s and has never been repiped, it's time for a free inspection, even if you haven't noticed symptoms yet.

We Know Cotati Neighborhoods Inside and Out

From the craftsman bungalows of Willow Glen to the ranch homes of Blossom Hill and the hillside properties of Almaden Valley — we've repiped thousands of Cotati homes across every neighborhood and zip code.

Cotati's housing stock reflects its history: the postwar boom of the 1950s produced thousands of wood-frame homes on crawl space foundations in neighborhoods like Rose Garden and West Cotati, while the tract home developments of the 1960s and early 70s brought slab-on-grade construction to Berryessa, Evergreen, and Cambrian Park.

These different construction eras mean different pipe materials and different repipe approaches. Our crews are experienced with both crawl space and slab repipes throughout Cotati, and we tailor our process to your home's specific foundation type and layout.

🏗️ Cotati Home Age Context

The majority of Cotati's single-family homes were built between 1950 and 1975. Galvanized steel pipes from this era have a typical lifespan of 50–70 years, meaning most of these homes are now at or well past their plumbing system's expected end of life. Even copper pipes from the 1960s can develop pinhole leaks after 50+ years of Bay Area water chemistry exposure.

Cotati Repipe
Permit Requirements

The City of Cotati requires a plumbing permit for any whole-house repipe. This is not something to skip; unpermitted plumbing work can create problems when you sell your home, void your homeowner's insurance, and leave you liable for code violations.

Repipe Champions pulls every permit on your behalf. We submit the application, schedule the inspection, and ensure your repipe is fully code-compliant before we consider the job complete. The permit cost is included in your quote: no hidden fees.

Cotati inspectors typically schedule inspections within 3–5 business days of permit issuance. In most cases, we can complete the repipe and have the inspection done within the same week your project begins.

Cotati Repipe FAQ

Answers to the questions Cotati homeowners ask us most.

Cotati whole-house repipe typically runs $5,200–$13,400 depending on home size, foundation, and pipe choice. Old Town homes around the historic Plaza with longer original galvanized runs and additional preservation review trend toward the higher end. Slab-foundation homes in Liman Way and Stage Coach Glen add 30–38% to the labor estimate. Repipe Champions provides a written, no-obligation in-home estimate for every Cotati homeowner.
Yes. The City of Cotati Planning Department requires a plumbing permit for any whole-house repipe. Permit costs typically run $220–$540. Properties on the historic Plaza and the original 1893 hexagonal townsite may require additional preservation review. Repipe Champions handles all filings on your behalf.
Old Town and Plaza-area homes typically have original galvanized iron supply lines. Mid-century Page Street, East Cotati Avenue, and Henry Avenue tracts usually have galvanized or first-gen copper. Liman Way and Stage Coach Glen from the 1990s–2000s use modern copper or PEX. A free in-home inspection confirms your material.
Yes — student rentals with high simultaneous fixture use accelerate wear on aging galvanized and copper supply lines, particularly at fittings and valves. We recommend a baseline inspection on any Old Town rental property over 50 years old, and we coordinate scheduling around tenant turnover when full repipe is needed. Cotati landlords often choose PEX-A for the longer service life and reduced future maintenance.
Cotati's moderate-hardness Sonoma Water supply is generally friendly to both materials, but PEX-A is the typical choice for student-rental properties because it eliminates the soldered-joint failure mode that creates costly mid-tenancy emergency repairs. PEX is also a better match for the slab-foundation homes in Liman Way. Copper retains some resale appeal in owner-occupied homes.
