Plumbing contractors hold the C-36 classification, covering repipes, drain and sewer work, gas piping and water heater installation.
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 #778930 is current, and check bond and workers’ compensation coverage, using the CSLB license lookup before signing a contract or paying a deposit.
