    The products are great. The installers did a good job in spite of having to deal with 3 days of rain. There was some cosmetic damage to a few walls during the removal of old windows, but these were repaired by the installers.

    The team who installed out windows did an outstanding job and were very professional, skilled, and knowledgeable -- not to mention very friendly. They fit the windows perfectly. With our permission, the team had to cut some back splash tile next to the windows in the kitchen in order for the window to fit properly. They did a very skilled and clean job of cutting the tile material and fitting the window. I will order more windows in the future.

    The crew and windows are excellent. They really made a difference this last summer with heat and sun. Can't wait until winter to see how they perform. Thanks again.

    We just had "Phase two" done on our home(because we were very happy with the "first phase"). The windows are solid and have a Cadillac feel to them. The installation process was top notch! My wife and I can't wait for "Phase three"!
