Do I really need a licensed restoration contractor in California?
Yes, California requires contractors performing restoration work to hold appropriate state licenses, and hiring an unlicensed contractor can void your homeowner's insurance. Always verify your contractor's license before hiring. Ask for their license number and check it through the California licensing board. Unlicensed work can also create serious liability issues if something goes wrong.

Why Hiring a Licensed Restoration Contractor Matters in San Mateo, CA
California (CA) does not currently require a state-level license for restoration contractors. When hiring for mold remediation in San Mateo, this means there is no state oversight verifying contractor qualifications — making your own due diligence even more critical. Look for contractors who voluntarily carry general liability insurance, are bonded, and can provide proof of workers' compensation coverage.
Ask for IICRC certification numbers and verify them at iicrc.org. Request proof of pollution liability insurance specifically — standard general liability does not cover hazardous material incidents. Check that the company has experience with your specific type of damage and can provide references from similar projects.
Local municipalities in the San Mateo area may still require permits for certain restoration jobs. Ask your contractor about permit requirements before work begins.
Restoration Contractor Certifications to Look For in San Mateo
- IICRC WRT (Water Restoration Technician) — required for water damage work
- IICRC FSRT (Fire & Smoke Restoration Technician) — required for fire/smoke damage
- IICRC AMRT (Applied Microbial Remediation Technician) — required for mold work
