They came, they measured, they came back to install, and unfortunately a mistake was made so they did not. This may sound negative, but they weren’t gonna try to make something work that wasn’t perfect, so it was the opposite. They came back very quickly with new windows that were of the exact size and installed it very fast and easy. I strongly recommend this company because of their integrity to do everything right and put in a high-quality product.
