"I was extremely happy with Hank the owner of Standguard Security Inc. I called Hank early in the day for information about an alarm system and he promptly came to my house that same day in the evening for an estimate and other options that he presented to me for my needs. I called him back and we set a time for the installation of a new system that was free ( just needed to sign up for a monitoring service). The day of installation Hank showed up with his tech guy Chris and promptly started to get to work. Chris the tech guy / installer was great and made sure everything was working correctly and answered all of my questions before leaving. They both were professional and I am very happy with the whole process."
