CSLB snapshot Oct 14
Community photos show the place named. Each is used under the license shown.
Match the license. Look for C-17 Glazing / D-28 Doors on the CSLB record. How to check a license, or check one yourself. Check the bond and workers' comp. Profiles with a matched license show the contractor bond and whether the business carries workers' comp or has certified having no employees. A crew on an exemption is a question to ask. Get two or three written estimates. Ask each for scope, materials, permit costs and a start date in writing, so the quotes compare like for like. Prices appear here only when real local quotes back them. Ask who pulls the permit. San Marcos Building Division ↗ says which jobs need one. Ask four questions on the first call. Do you take this exact type of job? Can you serve my address? When can you come, and is there a visit fee? Can you point me to a recent job nearby and a name to call? Prepare your message.
