Clarkston Windows and Doors replaced the windows in our entire home with their North Star line, and the results are phenomenal. Everyone we had contact with from the company was exceptional. The estimate was very reasonable, and the windows actually came in ahead of schedule. The chief installer was very professional, and did a wonderful job of explaining the process, pointing out some issues that needed to be addressed, and even finding a couple problems with the way our old windows had been installed, suggesting ways to fix the issues. The crew that came out was efficient, clean and neat, and extremely friendly. They obviously knew their work, and addressed every issue necessary. The new windows are so beautiful, they have totally added a new level to the look of our home. It was extra-nice to have everything done for us; no need to go back to stain or varnish interiors, etc. when the install was done. The interior finishing work, especially, is really above and beyond anything we could have imagined. We just had to sit back and admire our new windows! We have already been asked about them by other people, and the exterior painter we hired to paint the rest of our exterior trim (to match the windows) remarked that they were impressed with how well the windows were sealed and installed. We would highly recommend Clarkston Windows and Doors to anyone!!
