Based in Calimesa, Riverside County, Just Plumbing holds California contractor license #1093998, classified C36 (Plumbing). At the time this listing was compiled, the license was active with no suspension on record.
Plumbing contractors hold the C-36 classification, covering repipes, drain and sewer work, gas piping and water heater installation.
Working in the San Gorgonio Pass: Growth here has been fast, so the housing stock runs from older ranch properties to tracts finished in the last few years, and the two need 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 #1093998 is current, and check bond and workers’ compensation coverage, using the CSLB license lookup before signing a contract or paying a deposit.
