I had a garage door that wasn't shutting. I had all kinds of well-intentioned friends who came over and gave me fixes that only worked for about a day or two. It kept being a pain, so I finally threw up my hands and called City Garage Door. I found their number on a sticker in my house, so they must have been the people who worked on it before I bought the place. I called, they came out, and about five minutes later, they were done.
