Upgrade to cellular monitoring
Wanted to cancel landline and grand alarms were able to support this transition. Thank you very much for your patience and your support through this transition. I am very happy and satisfied with their service through the past few years.
An assisted review is collected by a contractor on behalf of the homeowner after their work is completed. The homeowner must confirm the text of the review and may make any changes she or he deems appropriate. The homeowner then assigns the contractor a review score out of 10. Assisted reviews receive the same scrutiny as other reviews and must follow our review guidelines.
I was in a bind when I was changing my windows and my existing Alarm Company was going to charge me an arm and a leg to re-hardwire each window/door. GrandAlarm came to my rescue and not just re-hardwire all windows and doors but offered me 6 months free as my prior alarm company continued to charge me. I am very happy in making the switch as they are customer focused, efficient and reliable
