Sewer repipe for Mill Valley homeowners. New pipe, permits pulled, surface put back. Online inspection booking.
Mill Valley sits at the base of Mt. Tamalpais and contains some of the most challenging sewer pipe scenarios in Marin County. The Downtown core and Blithedale Canyon were built between 1900 and 1925 with original clay sewer laterals — most are heavily root-intruded by the redwood and bay laurel root systems that dominate Mill Valley's landscape. Sycamore Park, Cascade Canyon, and Homestead Valley have a mix of 1920s–50s hillside cottages with clay or Orangeburg laterals also heavily root-intruded. The Strawberry, Tamalpais Valley, and Almonte expansion of the 1950s–70s produced Orangeburg and early ABS sewer pipe that is now well past 50-year service life. Mill Valley's tree-protection ordinances frequently require an arborist consultation before any sewer work proceeds, and steep hillside lots make excavation more complex than flatland Marin cities. Repipe Champions handles permitting and arborist coordination on your behalf.

Full excavation and replacement of your existing sewer line with new Schedule 40 PVC pipe. The most durable, longest-lasting solution, particularly for severely deteriorated or root-damaged lines.
These are the most common signs of a failing sewer line in Marin County homes.
When multiple drains in your home run slow simultaneously, the problem is almost always in the main sewer line, not individual fixtures.
Raw sewage backing up into your tub, shower, or lowest fixtures is a sign of a blocked or failed sewer line requiring immediate attention.
A strip of exceptionally green or lush grass over your sewer line is a classic sign of a slow leak: the sewage is fertilizing the soil above.
Persistent sewage smell in your yard or home often indicates a crack or separation in the sewer line allowing gas to escape.
Tree and shrub roots naturally seek moisture and nutrients in sewer lines. Once roots enter, they grow rapidly and can cause complete blockage.
If your Mill Valley home was built before 1980 and has never had a sewer camera inspection, scheduling one is a prudent first step regardless of symptoms.
Mill Valley is a steeply hillside community at the foot of Mt. Tamalpais with one of the most challenging sewer pipe inventories in the Bay Area because of the combination of original 1900s housing, dense redwood and oak root systems, and steep terrain. The Downtown Mill Valley core and Blithedale Canyon contain 1900s–1920s craftsman and Victorian homes with original clay sewer laterals — most heavily root-intruded by the redwood and bay laurel that define the local landscape. Sycamore Park, Cascade Canyon, and Homestead Valley have a mix of 1920s–50s hillside cottages with clay or Orangeburg laterals, also heavily root-intruded. Strawberry and Tamalpais Valley were built up in the 1950s–70s with Orangeburg and early ABS lines now reaching end of life. Almonte and Tam Junction have mid-century flat-lot housing with similar pipe profile. Mill Valley's tree-protection ordinances frequently require arborist consultation before sewer work to avoid damaging protected redwoods and oaks.
Mill Valley's pre-1940 sewer laterals are predominantly clay, almost universally root-intruded because of the redwood and bay laurel canopy that grows directly over most yards. Mid-century Orangeburg in Strawberry, Tamalpais Valley, and Almonte is at end of life. ABS lines from the 1970s–90s are generally sound but root intrusion at joints is widespread. Hillside properties present significant access challenges for the sewer replacement.
We run a camera through your sewer line and show you exactly what's there: pipe material, condition, root intrusion, and collapse points.
We write the price for the sewer repipe after the camera. The estimate covers the new pipe, the slope, the permit, and putting the surface back.
We handle all permit filings with the Mill Valley building department on your behalf. You never visit the permit counter.
We replace the sewer line, pass the city inspection, and restore sewer service. Most of these repipes are 1–2 days.
A permit is required for all sewer line work in Mill Valley. Unpermitted sewer work creates serious liability at resale and can void homeowner insurance coverage for related water damage.
