I'm actually not seeing a wire sticking out of the wall to connect to (in either picture).  There should be a wire sticking out somewhere, unless they also clipped that off, or stuffed it behind the window.  Also, did they leave behind the other half of the sensor?  As others said, wireless may be an option if all else fails in your scenario. 

Sorry to hear about your alarm wires.  There are a couple of differenct ways to go about resolving this issue.  We typically involve the servicing alarm company to make sure whatever is done to resolve the issue is accordance with their servicing the alarm system at the home.  They will be respoinsible and liable for the monitoring, so it is critical to involve them.  If possible to pull some additional length at the point of contact is helpful, or splicing on additional length is an option too.  If the wire issue gets too complicated, you may consider a wireless system.

I hope you found this helpful.  Please contact us directly of we can be of any service to you. john@assurancebuilders.com.

Veery few windows and doors have alarm sensors on them these days. Most monitoring is done with wireless motion sensors that cover windows and doors / entry points to the House. If you really want to have sensors on the windows then a good electrician will be able to extend the low voltage wires.
