I only needed 4 sunscreens to be redone so I brought them to the place of business. This saved me some money and was job completed in a reasonable amount of time, considering it is now the busy season. After I picked them up, one of the screens, which had a new frame, did not fit. I called Mark and he said to bring it down and he would reduce it which he did right away. Let me explain that the reason the new frame did not fit is because the old frame was bent to fit into the glass block window depression. I should have taken this into consideration when I asked for a new frame. Mark not only reduced it to the dimmensions that it should have been, but he also gave me some hardware for free so that I could install it propoerly. I would recommend Sunscreens by Mark!
