I am very happy that I have been using The Clean Advantage for as long as I have. I call them over to power wash the house and to clean the windows in and out. I would say that the work the staff has done for me has been consistent. They clean the windows every six months and perform a power wash in the fall. They have always been professional and easy to work with. I would definitely recommend the company to other people and I will continue to use them in the future. Overall, I am very happy with the service that they always manage to provide.
