Do not waste your time and money shopping, looking, comparing. This is unequivocally the best service around. Give this place a shot before trying elsewhere. Over the years, I've used at least 10 other business and individuals only to be disappointed time after time. Ask for Edwin. Not only he will leave your windows unblemished, spotless, but he is most professional: dependable, expeditious, and meticulous to no-end. And, if at the last moment you realize your windows need cleaning before your guests arrive, he will be there you. I'm loosing count of how many times I've called him to come to my rescue. He always has! Worth every penny of their very extremely reasonable prices. Don't wait; try this service; you'll never regret it. Christina in Brooklyn
