We had an alarm system installed by Granite Peak Alarm. If I could give them more than 5 stars I would. Professional, courteous, attention to detail are just a few things I can mention. I wish every company I've dealt with were like this company.

Granite Peak has provided us with outstanding service and top level products at the best prices. We have been very please with the quality of the camera systems and alarm systems they have installed for us.
We started using Granite Peak in September of 2018, and have a total of four camera systems and five alarm systems with them and have had zero issues with any of the systems or service. We have saved thousands of dollars over the past three years by going with them, and it has been a huge improvement over what we had with the nationally recognized company we were using at the time.

Granit Peak Alarm has done a wonderful job with continued customer service and great products. Railtown 1897 State Historic Park has seen a reduction in crime due to the new security cameras. They are prompt to help with any issues or questions and provide a very high quality of service. They work fast and efficiently with a clear knowledge of the security industry. We highly recommend this company and look forward to continuing to work with them.

Granite Peak Alarm is the best. I reached out to Sean for an alarm and camera system for my new home, he and his team delivered exactly what I asked for, on-time and on budget. They installed the alarm and a ten camera security system during the first heat wave of the summer without complaint. They also did a couple of extra service things for me without hesitation or extra fees. A great local company that goes the extra mile and cares about their reputation and making their customers happy. Highly recommend Granite Peak Alarm.

These guys are Crazy Awesome! They installed an HD Video Surveillance system for our shop upstairs and downstairs. 4 cameras that we can access any time to check on our shop, and two door bell cameras that are very responsive so we dont miss an important delivery or customer pick up. The Alarm system is top notch technology wise and when we had a couple accidental alarms by forgetting to disarm, the response team calls us within 30 seconds.. Going to have them do the same thing to our other business.. Very Professional People and we enjoy working with them... Would Highly recommend Granite Peaks

Glad to see a top quality alarm company that is locally owned and operated in the foothills. Sean was very professional and had great knowledge about the best technology in the market. He upgraded our commercial system and I was very impressed by both his technical support and service. I would not hesitant to recommend Granite Peak Alarm to both commercial and residential customers.

Simply said, Mark and Sean are just good human beings, and that is hard to find these days. They are reliable, trustworthy and go the extra mile to ensure you are safe. Great security cameras. Very clear at night. Level of service is outstanding, they even came back out when I forgot how to use everything. Family owned and operated. Best of the best.

We have a whole house service with surveillance cameras. Wow it was great to check the snow via the cameras before we came home. Love the security of having an alarm with remote set key fob. Very convenient. Friendly and prompt service!

I personally usually get three or more estimates, but in this case I called Granite Peak Alarm. I got a call back right away, and the owner came to my home the next day. He was very professional and friendly. After receiving his estimate, I did not feel the need for further estimates. I was most satisfied with the workmanship and their personalities. Thank you Granite Peak Alarm!
