Commercial Plumbing in Thousand Oaks

Licensed Master Plumbers. Job-Based Pricing. Free Estimates.

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.

Commercial Plumbing Services for Thousand Oaks Businesses

We handle the full range of commercial plumbing needs, from routine maintenance to large-scale system overhauls. California may require permits for commercial plumbing installations, alterations, and many repairs, with limited exemptions for minor work. Our team knows Ventura County plumbing codes and handles every project in compliance with applicable requirements.

Our commercial plumbing services include:

Commercial Drain Cleaning and Hydro Jetting: High-pressure hydro jetting clears grease accumulation, mineral buildup, and debris from commercial drain lines, including the recurring grease buildup common in restaurant kitchens.
Trenchless Pipe Repair: Pipe lining, pipe bursting, and directional boring restore damaged commercial pipes without tearing up driveways, landscaping, or interior flooring.
Camera Pipe Inspection: Video inspection technology locates blockages, cracks, and hidden damage inside commercial pipes without invasive digging or guesswork.
Backflow Prevention: We install and test backflow prevention devices for commercial properties, as required under applicable California code.
Leak Detection: We locate hidden water leaks that can lead to structural damage, mold growth, or higher utility costs.
Commercial Water Heater Service: Repair and installation for properties with high hot-water demand, including tankless options suited to commercial applications.
Fixture Installation and Replacement: Commercial restrooms, kitchens, and employee areas, including low-flow and water-efficient models.
New Construction and Tenant Improvements: Plumbing installations for new builds, tenant improvement projects, and system upgrades on existing commercial properties.

Restaurants, office buildings, retail centers, and healthcare facilities each carry distinct plumbing demand profiles. Preventive maintenance catches slow drains, worn fixtures, and early corrosion before they force a closure. We work with commercial clients to build service plans that fit their operations and reduce the risk of emergency shutdowns.
