American Drain Company is a family-owned commercial plumbing company serving Thousand Oaks and the surrounding Ventura County area. Our licensed Master plumbers bring over 40 years of combined experience to commercial properties of every size, from single-tenant retail spaces to multi-unit complexes. We bill by the completed job, never by the hour, so you know the full cost before we touch a pipe. Every service starts with a free, no-obligation estimate that covers materials, labor, and cleanup with no hidden fees.
Commercial plumbing systems run under higher daily demand than residential ones, and when something fails, a business can’t afford to wait. We maintain fast response times for both scheduled service and emergencies, and our 24/7 availability means Thousand Oaks commercial clients can reach us nights, weekends, and holidays.
