The men who cleaned the windows were very nice, polite, and professional. I was less impressed about the results achieved by their cleaning. They left streaking on most windows and didn't get in to the edges of the windows very well. I would say they were about average and when paying a premium you hope that the job will be excellent. They were to clean the screens and when I asked how they do that I was told they wipe them down with a damp rag- I expected more. I also did not like the way they handled payment- most companies I use either call in the credit card number to the office or they utilize Square- it took three weeks for my card to be charged which made me uncomfortable. I don't think that the best way is to have a contractor have a clients credit card number written on paper where it could easily be stolen.
