Colorado Security Alarm has been locally owned for more than 28 years. Above all, we are dedicated to a strong policy of customer service and quality installations. Unlike many of the larger alarm companies, we do no mass marketing or telemarketing and we install every system on a custom basis (no two systems are alike since no two homes or businesses are alike). With our radio reporting system, we are presently covering over 15,000 square miles along the Front Range of Colorado, and we are presently in the process of expanding coverage over the entire state! If you want high security, this is it! We provide ‘personal’ service. To us, you are not an account number. Rather, you are a person with a name. We never ask a customer for their account number when they call. Just tell us your name. Please don’t confuse Colorado Security Alarm with any other company whose name also starts with ‘Colorado Security’. We are not affiliated with any other company. References are available upon your request.
