Guidelines for Approving a Glazier for Your Project

In California, glaziers are required to meet strict licensing and insurance standards to operate legally, ensuring both professionalism and client protection. Any glazing contractor performing work valued at $500 or more must hold a C-17 Glazing Contractor License issued by the California Contractors State License Board (CSLB), which authorizes the installation, repair, and replacement of all types of glass systems. To qualify, applicants must demonstrate at least four years of journeyman-level experience, pass both a trade-specific glazing exam and a business and law exam, and undergo a background check. Beyond licensing, California requires glaziers to carry general liability insurance to cover potential property damage or injuries, as well as workers’ compensation insurance if they employ staff, providing coverage for job-related injuries or illnesses. Additionally, contractors must secure a surety bond, which offers financial protection to clients if legal or contractual obligations are not met. While not mandated, many glaziers also pursue specialized certifications in areas like energy-efficient glass or fire-rated systems to expand their expertise and credibility. By maintaining proper licensing, insurance, and professional certifications, glaziers in California not only comply with state law but also provide clients with peace of mind, knowing their projects are handled with safety, skill, and accountability.
