Based in Eastvale, Riverside County, Mr B’s Plumbing & Drain Cleaning holds California contractor license #1117071, classified C36 (Plumbing). At the time this listing was compiled, the license was active with no suspension on record.
A C-36 plumbing license covers water supply, drain-waste-vent systems, gas piping, and the fixtures and water heaters connected to them.
Working in the Inland Empire: Expansive clay soils are common across the inland valleys, and they move enough with the seasons to matter for foundations, flatwork and anything tied to them.
Before you hire any plumbing contractor: For any drain problem, ask whether a camera inspection is included before work is quoted. Guessing at a sewer line is how small jobs turn into large ones.
License status can change at any time. Confirm license #1117071 is current, and check bond and workers’ compensation coverage, using the CSLB license lookup before signing a contract or paying a deposit.
