Flagstaff Window Cleaning has been cleaning the windows in my house for approximately 9 years. As a year-round resident they are here 4 times a year and are excellent at contacting me to set up appointments during the times I have designated. They do excellent work and are trustworthy. Whenever a member asks for a recommendation for a window cleaning service, I enthusiastically recommend Kurt Brown and his crew. I have never had a bad experience with their work.
