We respond in minutes, not days. For most service calls in Sonoma and Marin County we can have a technician at your door the same day. For plumbing emergencies, we’re fully staffed around the clock — and we don’t charge after-hours fees for emergency calls.

We offer a $0 dispatch fee with drain services, and we give you a full upfront quote before any work begins. You’ll know exactly what it costs before we touch a thing — no surprise charges, no ambiguous line items.

We handle it all — water heater installation and replacement, drain cleaning, sewer line services, pipe repair and repiping, fixture installation, gas line services, water filtration, smart plumbing, and 24/7 emergency response. If it’s plumbing, we do it right.

Your main shutoff valve is typically located where the water line enters your home — often near the water meter, in a crawl space, or in a utility room. Turn it clockwise to close. If you can’t find it or it won’t turn, call us immediately and we’ll walk you through it while a technician heads your way.

Absolutely. Older homes throughout Sonoma and Marin County often have galvanized steel, cast iron, or polybutylene pipes. We specialize in repiping these systems with modern copper or PEX — improving water pressure, water quality, and reliability for decades to come.
