What our customers say…

Mitch was friendly and efficient. Thanks so much to NELSON ALARM for helping to keep our church building and church family safe.Rick ValeJuly 22, 2025

Mark quickly changed out our malfunctioning device, set it up in our security profile and completed everything very quickly. He was very polite and professional (and my pup loved him), thank you!Linda WaddickJuly 18, 2025

Great and fast service! Very friendly =) Thank you Mitch!Rebecca OttoJuly 11, 2025

Nelson Alarm has been my go-to for both home and business security for years. Their team is always professional, knowledgeable, and responsive. Mitch came out recently to reinstall a glass break sensor after I had a window replaced, and he was prompt, courteous, and efficient. I also appreciate that Nelson handles the monitoring for both my home and business systems, including cameras and alarms. As a business owner myself, I know how valuable reliable service and strong reviews are, and Nelson Alarm consistently earns both!Shelli McDonaldJuly 10, 2025
