Guidelines for Approving a Glazier for Your Project

In California, glaziers—professionals who install glass in windows, skylights, and other fixtures—are required to obtain specific licenses and carry insurance to operate legally. Below are the key requirements:

1. Licensing Requirements

• Contractor’s License (C-17): Glaziers who perform jobs valued at $500 or more (including labor and materials) must hold a C-17 Glazing Contractor License issued by the California Contractors State License Board (CSLB). This license allows them to install, replace, and repair all types of glass and glazing materials. The application process involves:

• Meeting Experience Requirements: Applicants must have at least four years of journeyman-level experience in glazing or a related field.

• Passing Exams: The CSLB requires applicants to pass both a business and law exam, as well as a trade exam specific to glazing.

• Background Check: Applicants must undergo a criminal background check.

For more information on obtaining a C-17 license, you can visit the CSLB website.

2. Insurance Requirements

To legally operate, glaziers are also required to have specific types of insurance to protect both themselves and their clients. These include:

• General Liability Insurance: This covers property damage or personal injuries that occur during the course of the work. California requires licensed contractors to carry general liability insurance to protect their clients from potential losses.

• Workers’ Compensation Insurance: If the glazier employs workers, they must have workers’ compensation insurance, which covers medical expenses and lost wages in case of job-related injuries or illnesses.

• Surety Bond: California requires licensed contractors, including glaziers, to post a surety bond. This serves as a form of financial protection for consumers in the event the contractor fails to meet legal obligations or contract terms.

3. Optional Certifications

While not required by law, glaziers may choose to pursue additional certifications to improve their skills and marketability. These certifications may cover specialized glazing systems, such as energy-efficient or fire-rated glass installations.

By ensuring that they are properly licensed and insured, glaziers in California not only comply with state laws but also provide greater peace of mind to their clients, knowing that their work is backed by legal and financial protections.
