Awesome Job All Around




Don Meyers did an exceptional job installing the window. There was nothing left to do inside the house and he even rehung the window dressing. The caulking inside was exceptional. Smoothed out perfectly with no painting required. On the outside the touch up work was minimal but necessary. He left caulking in place to prevent water from getting into the siding until I could touch things up and repaint. He cares about our home and was not just throwing a window in. Gravinas was the only company willing to replace a single window and worked with me and my military schedule to get the correct measurements and scheduled installation during my at home windows. I could not be more satisfied with Gravinas or Don. Matt

William was great!




William was great. Mark and his crew installed our windows and patio door, did a great job. Mark is coming back on Friday afternoon to finish out the trim on the patio door. We recommended Gravina's to a friend for windows.
