On Site

On Site operates out of Sun City in Riverside County and carries CSLB license #569390, classification B — General Building, C10 Electrical, C36 Plumbing. The license was active and clear when this listing was compiled.

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 #569390 is current, and check bond and workers’ compensation coverage, using the CSLB license lookup before signing a contract or paying a deposit.
