#1 Son Plumbing INC is a licensed California contractor based in Highland, San Bernardino County, holding CSLB license #1066881 under classification C36 — Plumbing. The license was active and clear when this listing was compiled.
A C-36 plumbing license covers water supply, drain-waste-vent systems, gas piping, and the fixtures and water heaters connected to them.
Working in the Inland Empire: The region sits between the San Andreas and San Jacinto fault systems, so seismic requirements are woven through the building code here in ways they are not everywhere.
Before you hire any plumbing contractor: For any drain problem, ask whether a camera inspection is included before work is quoted. Guessing at a sewer line is how small jobs turn into large ones.
License status can change at any time. Confirm license #1066881 is current, and check bond and workers’ compensation coverage, using the CSLB license lookup before signing a contract or paying a deposit.
