JS Concrete Co.

JS Concrete Co. has provided concrete services in the San Francisco area since 2003. The company handles residential, commercial, and industrial work across a range of scopes.

Services include slab on grade for residential walkways and complex commercial applications, foundations for new construction and existing retrofits, and site work such as sidewalks, parking lots, and walkways. The company also performs excavation, concrete removal and asphalt removal, home and building demolition, ADA upgrades including ramps and entryways, and saw cutting and concrete demolition.

In California, concrete contractors must hold a C-8 Concrete Contractor license issued by the Contractors State License Board (CSLB). Before you hire any contractor, verify their license status through the CSLB online license check tool. You can search by the contractor's license number (an 8-digit number found on their pocket license) or by business name. This step confirms the contractor is properly licensed and reveals any complaint history.

Most concrete work in San Francisco requires a building permit. The California Building Standards Code requires a separate permit before any structure is erected, constructed, enlarged, altered, repaired, or demolished. Permit requirements vary by city and county, so contact your local San Francisco building department to determine what is needed for your specific project. A licensed contractor can guide you through permit requirements for your scope of work.

When selecting a concrete contractor, ask whether they have experience with your project type—whether it is a slab, foundation, sitework, or demolition—and confirm they understand local code requirements. Request references and verify their license status before signing a contract.
