I'll start with the bad parts first. Don't count on them calling you til it's almost time for them to get there, and given their two hour window, they showed up at the end of it, not the beginning. Be prepared for that.
One other thing they did was to try to sandbag my expectations. I knew where the clog was, though, since I had tried to get rid of it myself, so I knew once he got started and got to the clog that it would clear up.
The guy who came to clean my drain, Andy, was very friendly and courteous. Once he got the machine started it was only about five minutes 'til that magical ""whoosh"" sound of the water rushing away, sucking air through the drain had come. Since it was a flat rate job, he stuck around to make sure the whole thing was cleaned out, slowly all the way out and back. He said that otherwise, although they're told to go in by hand and let the retractor pull it out, that otherwise a plumber could go right past a root ball and miss it.
I'd call these guys again.
