I do not remember the cost of the service. I have a contemporary house so I have large windows all over the house and their price was cheaper than other places that I priced. The guy who came out was very good, very nice and efficient. He cleaned up after himself and even reported to me that I had a window with a small break in it. He pointed that out to and showed it to me. He also told me what I should do about it. He also cleaned the outside of the windows on my greenhouse for no charge just because he was really intrigued that I had a greenhouse. So, I liked him quite a bit. I have not had any issues since the service was provided. He is reliable and he does what he says that he would do. He charges a reasonable price and he comes when he says that he is coming. He is probably all that you want from a window cleaner. We live in an expensive area so the price of the service seemed like a lot of money but I did not want to wash all the windows myself, and as I said, their price was comparable to other people in this area. I was actually just thinking about using him again but I have to wait until the pollens settle down.
