H M S Plumbing is a licensed California contractor based in Corona, Riverside County, holding CSLB license #1020035 under classification B — General Building, 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 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: 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 #1020035 is current, and check bond and workers’ compensation coverage, using the CSLB license lookup before signing a contract or paying a deposit.
