Capitol Cleaning has been taking care of my windows for many years. Their employees are friendly people, and they take a lot of pride in their work. The company trains its employees well, but there is some turnover as is natural in any business. You could tell one of the new employees this last time was still learning because he put a few of the screens back in wrong. But Capitol Cleaning takes good care of their customers. Peter, the owner, came out on a Saturday and corrected the issue. Another good thing about them is that their longer term employees really know what they are doing, and will inform you if something is not quite right with your windows. I really appreciate that! I give them Four and a Half Stars on Service and Total Experience!
