They did a good job. My main (only) complaint is that they were about 1.5 hours late.* Once they got there, everything was nice and smooth. The guys were friendly and knew what they were doing. All done in 3 hours.
*Was originally told that they'd be there between 2-3 pm; Joe called about noon to tell me they'd be about an hour later than that, but they didn't get there until 4:30. To be fair, trafic was heavy, but that's the sort of thing you should plan for. Since I only had the elevator until 6pm, I got nervous.
