Are Concrete Contractors in San Mateo, CA Licensed and Insured?

Most reputable concrete contractors in San Mateo, CA carry state licensing and general liability insurance. Our listing profiles surface credentials when a provider has supplied them, but a license that isn't listed here may still exist — always confirm directly with the provider before hiring.

Before hiring, ask for a copy of the provider's license number, current insurance certificate, and any industry-specific certifications. A legitimate concrete contractor will provide these without hesitation and won't object to you calling the insurer to confirm the policy is active and adequate for your project size.

California licensing requirements vary by trade and project value — check the California licensing board's public lookup tool to confirm the license is active and in good standing. Most states also publish any disciplinary history on the same lookup page, which is worth reviewing before signing.

Insurance coverage should include general liability at a minimum (typical minimums run $300K-$1M) and worker's compensation for any crew on your property. Without worker's comp, an injury on your job can become your financial problem — a risk that isn't worth any savings from a cheaper uninsured bid.

Watch for red flags: cash-only demands, no written estimate, pressure to sign before inspection, door-to-door solicitation especially after severe weather, or a business name that changes frequently across review sites. Any of these should be enough to walk away and keep searching.
