Our story
Rialto Plumbing Pros was built on a frustration our founders heard over and over: plumbers who quoted a replacement before they'd diagnosed the problem, tacked on surprise after-hours fees, and left homeowners in the dark. We decided to be the opposite.
Every job starts with a diagnosis, not a sales pitch. We test, we explain what we found in plain English, and we quote the price in writing before we start. Whether it's a 3 a.m. burst pipe in Rialto or a planned repipe in Fontana, you get the same honest process.
We know this region — Rialto's 160 mg/L hard water, the slab-on-grade tract homes prone to slab leaks, the aging galvanized pipe in older neighborhoods, and the clay sewer laterals that root out under mature trees. That local expertise means faster, more accurate work.
From our Rialto base we serve the whole Inland Empire — Fontana, Colton, San Bernardino, Rancho Cucamonga, Ontario, and dozens of communities across San Bernardino County, up into the mountains, and out to the High Desert. See every community on our service areas page, and explore what we do on our plumbing services page.
Credentials & Standards
Licensed, insured, and accountable
We hold ourselves to recognized standards — and we tell you how to verify us.
California C-36 Plumbing License
The C-36 classification covers water supply, waste disposal, gas piping, water heating, backflow preventers, water conditioning, and regulating valves. Verify any plumber's legal name, license status, and disciplinary record through the CSLB before signing.
EPA 24–48-Hour Drying Guidance
After water damage, wet materials should begin drying within 24–48 hours to reduce mold risk. We help you start mitigation immediately and document it for your claim.
ANSI/IICRC S500 Restoration
When professional restoration is warranted, we coordinate drying that follows the recognized ANSI/IICRC S500 standard of care.
City of Rialto Permits
Some plumbing and water-heater work requires a permit. We confirm requirements with the City of Rialto and put permit responsibility and inspection handling in writing.

Reviews
What Rialto Homeowners Say
“Woke up to a flooded garage from a burst pipe. They were here in 40 minutes and had it fixed before noon. Lifesavers.”
“Replaced our ancient water heater same day and explained every option. Honest pricing, no upsell.”
“Finally fixed the slab leak two other plumbers missed. Professional, clean, and they respected the house.”
“Our main line kept backing up. They ran a camera, showed me the root intrusion on screen, and jetted it. No more backups.”
“They found a hidden leak behind the wall in under an hour with their electronic gear. Saved us from months of damage.”
“Repiped our 1920s home with PEX. Careful with the plaster, permitted everything, and pressure-tested before closing up.”
