Subject: Window Installation


Dear Mr. Kypreos,


Thanks for stopping by to check on the windows we had installed in our kitchen on July15, 2010; \"grew\" customer service. A few years are, we had other windows installed and like them very much so we decided to do the kitchen as well. I must say the installation team headed by Gino did a marvelous job, particularly with the big bay window.


We have recommended your windows to several of our friends one of whom already purchase them.
