About the C-8 — Concrete License
The C-8 Concrete license authorizes contractors to mix, pour, and finish concrete for a wide range of residential and commercial applications. This includes foundations, driveways, patios, sidewalks, retaining walls, and decorative concrete work like stamping and staining. Concrete is one of the most versatile and durable building materials, and proper installation requires significant skill and experience. Factors like mix design, reinforcement, curing conditions, and finishing techniques all affect the final product's strength and appearance. California's seismic requirements add another layer of complexity, particularly for foundation work. When hiring a C-8 contractor, ask about their experience with your specific project type, the concrete mix they recommend, and how they handle weather-related scheduling challenges.
About the D49 — D49 License
A D49 (D49) licensed contractor in California is authorized to perform specialized work in their trade area. California's Contractors State License Board (CSLB) requires contractors in this classification to meet education, experience, and examination requirements before receiving their license. When hiring a D49 contractor, always verify their license is active and in CLEAR status, confirm they carry adequate insurance, and get a detailed written contract before work begins. Licensed contractors must maintain a $25,000 contractor bond and comply with all applicable building codes and regulations.
💡 Tips for Hiring a Concrete Contractor
- Ask about the concrete mix design and reinforcement planned for your project
- Discuss decorative options like stamping, staining, or exposed aggregate
- Inquire about curing time and when you can use the finished surface
- Get a plan for drainage and slope to prevent water pooling
- Ask how they handle weather delays, as concrete work is weather-sensitive

How long does concrete take to cure?
Concrete reaches about 70% of its strength in 7 days and full strength in 28 days. However, you can typically walk on it after 24-48 hours and drive on a driveway after 7 days. Your C-8 contractor will advise on specific timing for your project.
Do I need a licensed D49 contractor in California?
