We provide residential and commercial plumbing solutions across Marin County designed to keep your plumbing system running safely and efficiently.
Clear stubborn clogs and restore proper drainage with professional drain cleaning. We use advanced equipment to remove buildup, tree roots, grease, and debris without unnecessary damage to your pipes, a common need in Marin’s older homes and mature, tree-lined neighborhoods.
A damaged water line can cause low water pressure, higher utility bills, and costly property damage. We diagnose the problem quickly and provide reliable water line repair or replacement for Marin County homeowners and businesses.
Our team specializes in sewer line repair, replacement, and trenchless solutions wherever possible, minimizing disruption to your Marin property while restoring your sewer system. Sewer work is our foundation, and we bring that same expertise to every job.
Hidden leaks waste water and can cause serious structural damage over time. We use modern, non-invasive leak detection techniques to locate leaks accurately and recommend the most effective repair.
Whether you’re upgrading a kitchen or bathroom or repairing a malfunctioning fixture, we install and repair faucets, sinks, toilets, garbage disposals, shower fixtures, and bathtubs.
Keep your hot water flowing with professional water heater services. We handle installation, replacement, and repair for both traditional tank and tankless water heaters.
Older plumbing systems — common throughout Marin County — can develop recurring leaks, poor water pressure, and corrosion. Our repiping services replace aging pipes with modern, durable materials for improved reliability and long-term performance.

Yes. Whenever site conditions allow, we use trenchless methods to repair or replace sewer lines with minimal digging. Trenchless work protects your landscaping, driveway, and hardscape while restoring your sewer line — often faster and with less disruption than traditional excavation.
Cost depends on the length and depth of the line, the type of damage, access to the pipe, and whether a repair or full replacement is needed. Because every property is different, we provide a free, upfront estimate after diagnosing the issue — so you know the price before any work begins.
In most cases, the property owner is responsible for the sewer lateral that runs from the home to the city’s main line, while the municipality maintains the main itself. We can inspect your line, identify exactly where the problem is, and explain your options.
