Plumbing Expertise Across Ontario

Ontario stretches from the century-old homes of the Old Ontario historic district near Euclid Avenue all the way out to the newer neighborhoods that grew up around Ontario International Airport and the Ontario Mills shopping corridor. That range gives Royalty Plumbing Inc a front-row seat to nearly every era of residential plumbing in the Inland Empire, inside a single service area. Homes near downtown Ontario often still run original cast iron sewer laterals, while properties closer to the airport were built with modern PEX and PVC from day one.

Why Ontario Homeowners Choose Royalty Plumbing Inc

Royalty Plumbing Inc calls Ontario home. Gabe Ruiz built this company here in 2023 after years running two earlier plumbing operations in the same area, so our roots in Ontario go back further than our current name. A wide range of housing stock inside one city (Source: U.S. Census Bureau, 2020) means we’ve had to stay sharp on everything from century-old cast iron near Euclid Avenue to modern manifold systems in newer subdivisions.
In our experience, the biggest mistake homeowners make in older Ontario neighborhoods is waiting on a slow drain or a damp spot on the slab, hoping it resolves on its own.

Good to know

Frequently Asked Questions

In many cases, yes. Homes near Euclid Avenue and the historic district often still have original cast iron or galvanized pipe that requires careful, sometimes more involved repair, while newer homes near the airport corridor were built with modern PEX or PVC. We tailor our approach to the age and material of your specific home rather than using one method everywhere.
Cast iron was a common material for sewer lines in homes built through the mid-1900s, and it’s known for being durable but eventually prone to rust, cracking, and root intrusion as it ages. Many homes in Ontario’s older, established neighborhoods still have some cast iron in the sewer line. We can inspect and tell you exactly what your home has.
Most single-family whole-house repipe projects in Ontario finish in two to three working days, depending on the size of the home and how the existing pipe is routed. We give you that timeframe in writing before the work begins so you can plan around it.
Yes, especially on streets with mature, established trees near the historic district. Roots seek out the moisture inside aging cast iron or clay sewer lines and can eventually crack or block them. Regular drain cleaning helps catch root intrusion before it turns into a full blockage or backup.
Yes, we serve all of Ontario, including the neighborhoods around Ontario Mills and Ontario International Airport, not just the older sections of the city. Wherever your Ontario address falls, we can put together a written quote for the work you need.
