The installer ripped out our window alarm wires without saying a word to my husband, who stayed home from work with them, and could have answered any question about whether to keep the wiring intact or available in some way for the alarm company to come in and keep the system intact. After the installer left, and we went to set our alarm, we learned that there was a "fault" at every window.
Could not set the alarm without bypassing the windows. Then the alarm company either had to come and rewire every window for a fee of more than $75 each or leave our lower floor windows unprotected. We decided to put in motion sensors instead to protect these areas. When I called the window company, they told me that alarms aren't their problem.
The alarm company told me that usually people arrange to leave the wiring exposed so the alarm company can come in and just put new sensors on, without having to figure out where the existing wiring is, etc.
the installer should have said something, instead of damaging our property, so we could have called the alarm company and received instruction on how to handle it. I had a death in the family, so I could not pursue this issue with the window company and am still upset about it.
Monetary Loss: $750.
