Squeeky Kleen is awesome! Invariably, if they've done your windows, and it's rained in the two-week period, they'll redo them at no charge. They've been very good to us, and they've done an excellent job, especially considering we have old, square window panes that are little and difficult to clean. Laboriously, they got after them, and they did a fantastic job. They were very accommodating when it came to scheduling as well. I would recommend them.
