If you're not able to open your garage door at all, or the mechanism is moving slower than it used to do, and you've made all the repairs needed during inspection of the door itself, the problem is likely rooted in the garage door opener.

Since most yards entertain play activity including baseballs and other sporting equipment, it's no surprise that garage doors experience broken glass from time to time. Regardless of the cause, it's important to repair glass quickly, since broken glass in a garage is a safety issue, a security problem, and an invitation to every bird and insect in the neighborhood to take up residence in your garage. Fortunately, it's not difficult to replace a pane of glass. The techniques are exactly the same as for replacing glazing in a house window.
The tech that was scheduled to repair my broken torsion spring was professional and very detailed. He arrived 30 minutes early, was completely prepared to do all the work. He let us know every step before he took it and was upfront about the costs and ways to save money and remain safe. My garage door was fixed within 1 hour. I would highly recommend!
