Based in Wildomar, Riverside County, R M Plumbing INC holds California contractor license #455466, classified C36 (Plumbing). The license was active and clear when this listing was compiled.
The C-36 classification covers complete plumbing systems — supply lines, drains and vents, gas lines, water heaters and fixtures.
Working in southwest Riverside County: This corridor has grown fast, so the housing stock ranges from 1970s tract homes to work finished last year — and the two need very different approaches.
Before you hire any plumbing contractor: On a water heater replacement, confirm seismic strapping, the expansion tank and the venting are all included. Those are code requirements, not upsells.
License status can change at any time. Confirm license #455466 is current, and check bond and workers’ compensation coverage, using the CSLB license lookup before signing a contract or paying a deposit.
