I really love my windows after Don and his crew have cleaned them. They're so clean that they disappear! I have a lot of windows, and cleaning them myself is impossible - I don't like ladders. Don's taken care of my windows for years and I highly recommend him to all my friends and neighbors, and those who have used him agree with me that he's the best. My neighbor called for an estimate and he was here that afternoon, and they were cleaning the windows a day or so later. It's obvious that they take pride in their work, and you can take pride in your house when they're through! They're the best!!
