ADT Mississauga

We had our old system replaced, and can say that the monitoring is good (a couple of self-inflicted alarms where they called immediately), but the install was painful. Workers left a mess all over the house (bits of wire are bad for dogs), old equipment was left where it was ripped out, alarm sensors not consistently placed, etc. We held payment until the Sales person + head of install team came back and resolved our issues (i.e. made the install clean and consistent). Recommend that you hold back payment to make sure they do the job the way you want it.
