Professional installation was a joke. Had they given me the wiring tools, I could have done a better job my first time around.
He didn't want to get up into the attic, so most of the wiring cable comes up through the floor (away from the baseboard), through a wall, and then runs along the top of the wall/ceiling molding.
It was the first thing a couple of friends noticed when they came to visit.
Would I recommend them to install the wiring?? NO.
Maybe it was just that particular guy, but it left me with a sour taste about that part of the service.
