Serge is a very punctual and organized person. First day I called he came on the same afternoon to give me a free quote. Later he told me his baby was born on that day! He did such a good job cleaning all our windows, doors, including the screens and the window sills. I also like that he is such a good communicater, he would let me know what was the next step all the time so I always knew what to expect and where he was during the few hours.
