A clogged drain can go from a minor inconvenience to a serious problem fast — especially during Marin County's rainy season when drainage systems are already under pressure. Big Island Plumbing provides professional drain cleaning services for homeowners across Greenbrae, San Rafael, Larkspur, Mill Valley, and throughout Marin County. Whether it is a slow kitchen sink, a backed-up bathroom drain, or a main line blockage, our team uses professional-grade equipment to clear the problem at its source and restore proper flow.

Store-bought drain cleaners often mask the problem and can damage your pipes over time. Our licensed technicians identify what is causing the clog — grease buildup, hair, soap residue, tree root intrusion, or something deeper in the system — and clear it properly so it does not keep coming back. We provide upfront pricing, explain what we find, and make sure the job is done right. Homeowners in San Anselmo, Fairfax, Sausalito, Novato, and across Marin County trust Big Island Plumbing for drain cleaning that actually solves the problem.

Tankless water heaters are an increasingly popular choice for Marin County homeowners looking to save space and reduce energy costs. Our team sizes the right unit for your household, ensures proper gas or electrical connections and venting, and completes the installation to code. For traditional water heaters that can be repaired, we give you an honest assessment and upfront pricing so you know your options before any work begins. Homeowners in Mill Valley, Larkspur, San Anselmo, Novato, Petaluma, and across the region count on Big Island Plumbing for water heater services they can depend on.

Many homes in Marin County are decades old, and aging pipe systems can cause recurring leaks, discolored water, reduced water pressure, and potential health concerns from outdated materials.

We replace deteriorating pipe systems with modern, durable piping that restores reliable water flow, improves water quality, and protects your home from future plumbing failures.

Our repiping process begins with a thorough inspection of your existing plumbing to assess the scope of work needed. We explain your options, provide upfront pricing, and complete the project efficiently while minimizing disruption to your home. Our team has completed repiping projects across Marin County — including verified permit work in San Anselmo, Mill Valley, Novato, and Larkspur.
