Great Oaks Construction operates out of Anza in Riverside County and carries CSLB license #885346, classification B — General Building, C42 Sanitation System. At the time this listing was compiled, the license was active with no suspension recorded.
This trade handles everything between the house and the main or the tank: clearing and repairing blocked laterals, replacing collapsed clay or cast-iron sewer pipe, installing and servicing septic systems, and restoring failed leach fields.
Working in southwest Riverside County: This corridor grew quickly, 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 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 #885346 is current, and check bond and workers’ compensation coverage, using the CSLB license lookup before signing a contract or paying a deposit.
