Fred came to my apartment twice given he needed more time and parts after the first day. He took time on what I presume to be his lunch hour to come back.
He was very concerned with the quality of his work and made sure the system was backed correctly to take a lot of weight. My building is old so there were some problems finding good studs. But he got the parts and made it happen!
He was more expensive than I expected and has a minimum job fee, but I'd still use him again because he does things right and it looks like it will last.
