Granite Peak Alarm is a fantastic local Alarm company here in Calaveras county.

Install the fantastic alarm system with cellular backup, which is monitored 24/7. I have my technicians cell phone number so if there's ever a problem, I can give him a call and he answers quickly and lets me know if there's an issue but so far no problems and the system looks fantastic. The prices are very reasonable for the product and service they offer. There are a lot of unscrupulous companies out there trying to rope you into long term monitoring contracts as that is the gravy of recurring revenue for alarm companies (I was involved in that industry) in my experience and dealing with them, but this is not one of them. Very honest and always happy to help. You can always reach someone which is so important. Today's customer service is lacking with many companies and at least with Granite Peak, I haven't had to worry about that. 5 stars all the way!

After a door was opened the alarm started blaring in my house. I called the number on the equipment and was told everyone had left for the day but they would have someone from after hours call me to help get the alarm off. I never received a call back, luckily my husband is able to do electrician work and was able to deactivate the system. I called again this morning to have them come remove the equipment t and was told I would be charged. This company should be called Horrible Service
