"The installation of the new windows went ok. Only complaint I had is that the color selection was limited, and the white I had to select did not match the off-white of the window trim."

"Have worked with Jeremy and Larry at 1st Security for a few months now and they're great. They're far more responsive than any other alarm company I've worked with and they're focused on meeting your needs, versus endlessly trying to get you to buy more services and sensors that you might not need. In the house I just bought some other alarm company had installed a window open/close sensor on a window that doesn't open - probably fooling the prior senior citizen owners to pay more for more equipment they didn't need. I rest assured that 1st Security would never do something so foolish and greedy. They're good, honest people, and this is something that's unfortunately hard to find in the alarm business. I recommend them."
