I had Grand Alarms installed in my first home back in 2001 and chose them again for my second home this year. The service was great. they took the time to explain options over the phone and were able to schedule an install the day that I needed it. The technician was very professional, clean, and had the alarm system installed and functional as promised. After moving in I installed an additional door to the outside - I called the office to schedule someone to come in and add an additional contact to this new door and they sent someone immediately, it was done within an hour of me making the phone call and at no charge. There have also been a couple of times the alarm has gone off (happens with kids) and they called right away to make sure all was okay. I would definitely recommend them to anyone needing an alarm system.
