Garage doors are heavy and as such involve a lot of forces, particularly the torsion springs. These springs, which have limited lifespans, are under a tremendous amount of tension and if that force is released unexpectedly, bad things can happen. In addition to the springs, the other components of your garage door system routinely see plenty of weight and pressure and can easily crush fingers if not handled correctly. So the number one reason to have your door serviced by a professional is safety.
The other consideration is the value of your garage door. A garage door that is not serviced properly can lead to complete garage door failure resulting in damage to vehicles and property inside the garage. It could also require a whole new garage door installation which will be much more expensive than any service call.
Our advice: don’t mess around with your garage door. For safety’s sake alone, always call a garage door repair professional for service.
