I can tell you this, Superior Door Service, Inc. are extremely professional! This is a true story! I had them come out and fix an existing garage door. I needed a spring replaced and a new remote for it. While they were here making the repairs my neighbor called the police and told them that Superior Door Service was making his garage door go up and down. The police arrived and spoke to the installation man and checked everything out. I was very impressed with the professionalism of the technician. He was able to maintain his composure and deal with the police officer and get his job done perfectly throughout this whole ordeal! I am very impressed with them and I can assure you that if I ever have to have any other work performed on my garage door I will be calling them!
