Commercial Plumbing for the Inland Empire
Regal Plumbing & Rooter provides full-service commercial plumbing for businesses, restaurants, apartment complexes, HOAs, and property managers across our service area. Our owner brings 20+ years of hands-on experience, and under California Contractor License #1097482 we handle commercial plumbing work, from routine repairs to emergency calls. We understand that plumbing issues in commercial properties mean lost revenue and unhappy tenants. That is why we prioritize fast response times, minimal disruption to your operations, and clear communication throughout every project. We serve commercial clients in Ontario, Rancho Cucamonga, Fontana, Pomona, Corona, Upland, West Covina, and Chino.

How We Work
Why Choose Regal?
Free Camera After We Clear It
On a drain call we cable the line first, then we typically run a camera through it free of charge as a courtesy, so you can see why it backed up.
Shielded Bands, Not Rubber
On sewer repairs we typically use a heavy-duty Husky band with a full metal shield, not the rubber Fernco band held on by two hose clamps.
30 Minutes to an Hour on Emergencies
A real person answers around the clock, and we can typically reach an emergency call within 30 minutes to an hour.
1-Year Warranty on Labor
Our labor comes with a 1-year warranty. Anything we note on your invoice as not covered by warranty isn't included.
