I hired Mr. Windows to clean a 2-story single family home in the Fall of 2016. Everything went smoothly. Fast appt and on-time. They cleaned glass inside and out , sills , and screens. They did a great job and I would hire them again. When getting quotes from any window washer its important to determine whats included or not ( ex: how much more for sills?). I learned that next time they come there could be an upcharge to clean the exterior windows of the second story that are on a hill due to tricky ladder work.
