Chances are pretty good if you simply replace your old garage door system with a new one, you would not be entitled to any compensation.

If you want peace with your neighbors, just replace the old system and call it good.

If you can't replace it right now, or you really want the neighbor to take responsibility, then I would recommend that you send a letter to the neighbor that outlines the problem very specifically and inform them that they cannot continue to open your garage door and leave it it open because you are concerned about the pipes freezing and about intruders breaking in. Remind them that this problem did not exist until they installed their system and you would really appreciate their assistance in getting this problem resolved.

You do not have a cause of action against the company that installed their garage door system because you didn't have any type of contract with them. You do potentially have a cause of action against the neighbor. Have you considered having an independent garage door installer come out and assess the situation? Just because the tech from the original installation company was clueless doesn't mean another company wouldn't be able to fix this.
