We have used The Clean Shiny Window Company for several homes and have always found their work professional. They are courteous and prompt and always do the work within the time allotted. They are cleaning the windows on our very large homes that have been under construction. These windows are usually dotted with stucco, have stickers on them and often have a great deal of paint. The Clean Shiny Window Company is able to make the windows look great. I recommend Chris Biel and his company to anyone that wants their windows cleaned
