At Sentry we are proud that over 90% of our new alarm system business is referred to us. This says a lot as most of our competitors out spend us in advertising. We prefer to spend money taking care of our customers. For example we are available 24 hours a day, 7 days a week. When you call us, you get us, not some offsite supposed support center or an out of state call center that cannot even pronounce the town you live in correctly. Feel free to give us a test. Call us. You'll be pleasantly surprised.
