Scheduled appointment making it clear I had a large picture window that needed multiple people to get in and out. The first appt. One guy showed up telling me he needed 2 people to do the work. Second appt. I called to confirm they were sending 2 people and was told that they were running behind and there wasn't enough daylight left we had to reschedule. When the crew came for the third appt the bill was recalculated to be almost 50 bucks more. I was desperate being the day before thanksgiving. I will say they did a GREAT job and there is nothing like having all your windows clean at the same time. I think I will try someone else next time and see if I have a better experience.
