LICENSING:  A very important issue for you the consumer...Keep in mind any contractor performing a job in which the total cost of the project is more than $300, the contractor MUST be licensed by the Contractors State License Board (CSLB).   Licensed contractors are subject to laws designed to protect the consumer! Unlicensed contractors may give you a low bid while also giving you the risks of financial and legal consequences from injury or property damage incurred by others.  Just being given a license number on a business card, proposal or contract, does not mean the license is valid.   Before you sign anything, call the Contractors State License Board at 1-800-321-CSLB to make sure the contractor is properly licensed for the type of work to be performed and that the license is in good standing.   Any person or company, even a CSLB licensed contractor must have a special consumer affairs license beginning with the letters ACO (Alarm Company Operator) before doing ANY work on a burglar alarm system or its components.   If you would like to check if the company holds a valid California license to do burglar alarm work,
