We tried to fix the garage door ourselves. We shouldn't have wasted the time. (We were about to replace the whole unit.) Dealing with Steven this garage door company was so easy. He and his assistant, John, fixed the problem in one hour. Replaced a broken part for just over $100, and adjusted the rails, and lubed the springs and all hinges. All work warrantied for one year. Money well-spent. Honest, VERY hard-working. I wish more people were this self-directed and helpful.
