We used Grand Alarms for rough-in and installation of alarm and central vac in our newly built home. We also got garage door openers and cable rough-ins before the house was built. Overall I am happy with the service. The central vac was roughed in and and installed without issue, as was the garage door opener. The alarm rough-in was done as per specs, the technician that completed the installation did a good job and was very nice and professional, however it did take him twice as long as I expected (2 days) to complete the installation so it would have been helpful if 2 technicians were sent as they knew the size of job to be completed. The house was also pre-wired for tv/tel/smart wire. We did have issues with completing the activation of the jacks (however the issues were not caused by Grand Alarms). The sales rep in the office (Liz Aversa) was exceptional in trying to resolve my issues; however, i was not so pleased with the 2 technicians that were sent to address the issues. They were not able to fix the issues as per what was requested and confirmed could be completed in advance by the service dept; in addition they were not very professional. Specifically though, I must thank Liz for taking my endless phone calls working hard to understand the technical aspects so that she could address my issue. She is terrific. All the office/sales reps (Liz, Angela and Amandeep) were all excellet. I am satisfied with Grand Alarms for all areas but the cabling activation.
