Very happy with the quality of the sliding glass door and how efficient and professional Al and Nichole worked together to get it installed. Their attention to detail from the actual install, to the constant cleanup during the process was amazing. They also took the time to make sure we were shown everything about the door. Also very happy with all the people we dealt with in the store. Very friendly and knowledgeable about the product. Thanks to everyone.
