UPDATE: I had called in 2018 to ask why the system was constantly rebooting. They said they needed to charge a service fee for coming out which I agreed to, but then said it wasn't worth it for ME to pay the charge. It's like they didn't want to come out. Anyway, I dropped it. In 2019 I had an electrician install some GFCI outlets and the alarm went wonky while he was here. He told me it was likely a faulty window sensor, bypassed the one he thought might be problematic, and I haven't had a problem since. So much of SG3's follow-up service.
My older home alarm got fried after a blackout in December and had been long past its warranty period. After calling a few alarm installation places for estimates I decided to go with SG3.
George was friendly and very helpful in helping me choose a replacement unit and discussed different panel and zoning options. George and Brody arrived as scheduled and had the unit installed and wired to existing sensors in about 1.5 hours. He showed me how to operate the main and secondary panels and made sure I knew how to bypass sensors and reprogram the master alarm codes (just the process of reprogramming the codes, to be clear) before leaving. He assured me that I could call him anytime if I had any questions.
Both George and Brody were very professional and efficient. I would recommend them for your home security needs!
