White Mark

White Mark is a licensed California contractor based in Riverside, Riverside County, holding CSLB license #506653 under classification C27 — Landscaping, C42 Sanitation System. The license was active and clear when this listing was compiled.

Septic and sewer work covers septic tank installation, pumping and repair, leach field replacement, sewer lateral repair and replacement, trenchless lining and pipe bursting, and camera inspection of buried lines.

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 septic or sewer contractor: On septic, ask which county environmental health permit the work requires. Tank replacement and leach field work are permitted and inspected at the county level, and an unpermitted system is a problem at resale.

License status can change at any time. Confirm license #506653 is current, and check bond and workers’ compensation coverage, using the CSLB license lookup before signing a contract or paying a deposit.
