  • Mike B.

    Colonnade Security did some repair work on our system (originally installed by a different firm). They were prompt, friendly and professional in every regard with an attitude of doing just what was asked and required rather than trying to sell us additional services or equipment. We thoroughly recommend them.

    We have been working with Colonnade security for over ten years now. I first had them install a security system in our home to help protect my most important investment. Colonnade was wonderful, they came and installed our security system, answered all my questions and made sure I felt 100% comfortable. I have always felt super safe and secure having them monitor my home. I appreciated so much their wonderful support and customer service, that when I opened my first business I wanted to have them also protect my business. I now have my home and two business protected by Colonnade security and it has been my best decision yet. They are always there when I have questions, are very quick, courteous and provide top notch customer care. I am very lucky to have found such a wonderful company to work with!
    Thanks Colonnade security!

    We have been customers of Colonnade Security for the past four years. During this time they have consistently provided us with excellent service. On one occasion a sump pump sensor was malfunctioning the day before we were to leave on vacation, Colonnade Security fixed the sensor for us within a few hours. They are prompt, professional and reliable and we would highly recommend them.
