they did our windows recently and did a pretty poor job, there were streaks on some of the windows, cobwebs left in some windows, and the worst part was they broke 2 screens they were completely bent. We had some young gentleman come to our door recently offering window cleaning and thank god we scheduled them, they did an excellent job and left the windows sparkling and most importantly did not bend any screens.
