Graszer Garage Door (GGD) is a family-owned and operated business started by Frank Graszer. Frank has a very extensive background in troubleshooting and repair of garage doors and automatic opener systems. GGD is committed to giving each customer exceptional service while ensuring every project is done right the first time. A garage door and the parts on it, only function as well as the person working on it. We believe that the most valuable thing a customer can pay for is knowledge. We sell the best parts with the most knowledge at a great price.
