Shirley Haber from Vaughan

From the first call we made to get an estimate they were professional, helpful, and provided us with all the information we needed. Sammy was very friendly, accommodating, and just built us the best fence!! he is very reliable, on time, most importantly there were no surprises (which is hard to find these days). Will definitely use his services again!

I have been with Grand Alarms for over 10 years. their service is great, they are reliable, and always very helpful. I called to get some monitoring help (changes) and Fara, customer service, was very patient, informative, and helpful. She was able to answer all my questions and set me up with a technician right away.
