Both John and Richard who replaced the existing sliding door unit and installed the french doors, the clear glass in the existing bi-folds and replaced the front door with a new door, were excellent. John was clearly a person who wanted to make sure the work was quality. His attention to detail resulted in a great looking french doors. Richard did a fantastic job on the front door and replace the glass on the existing bi-folds. He gave us some great advice. We appreciated their time. We really like the french doors to the enclosed decking. This will be a great feature for the warmer months. So good.
