We live in a historic home with the crank out windows - lots of those small panes. Uptown cleaned all of our windows inside and out. I don't know how, but there were no streaks. This is a very detailed job and the windows all looked terrific. We were preparing for an open house which made this very important to us. We were extremely pleased and are signed up for a scheduled cleaning in the future. If you're like me, window cleaning was on my yearly to do list and now I never have to think about it again. And no more dreading monsoon season because I can just call and get an extra cleaning done. Thank you Uptown Window Cleaning.
