Tony, the sales representative, was prompt, courteous and professional. He presented us with several options for the replacement of 3 basement windows. We decided to go with the full frame replacement and chose the single slider basement windows. The windows were produced within a reasonable time (and as per Tony's estimated time). The installation date was re-scheduled several times mainly due to weather. On the day of the installation, Vladimir, the installer, was on time, and completed the work in a professional, effective and tidy manner.
