SDW Construction

SDW Construction handles concrete driveways, patios, and new construction across the San Francisco Bay Area. The company is led by owner Sam White and operates Monday through Friday, 7:30 AM to 5:30 PM.

On the company's website, the team describes their work process from site assessment and grading through concrete pouring, finishing, and sealing. They address Bay Area soil conditions, drainage, and seismic considerations specific to the region.

In California, concrete contractors must hold a C-8 (Concrete Contractor) license from the Contractors State License Board (CSLB). Before starting work, check with your local building department—in San Francisco or your city—to determine whether your project requires a building permit. Most concrete work, including driveways and patios, needs one. A licensed contractor can help coordinate permits and inspections as part of the project.

To verify a contractor's license, use the CSLB online license-check tool. You can search by license number (shown on the contractor's plastic pocket license) or by business name. This database also discloses any complaints filed against the contractor. Before you sign a contract, confirm the license is current and in good standing.

Ask your contractor about their experience with Bay Area soil, drainage, and seismic conditions—factors that affect how concrete is installed and cured in this region. Discuss the permitting process, site assessment, and the timeline from grading through final inspection. A clear contract should outline the scope, schedule, and how permits and inspections will be handled.
