Once your door garage has failed to serve its purpose as an easy but secure opening of your garage, you should consider replacing it immediately.  Garage companies can easily do it for you at very affordable prices. Garage manufacturers usually base their product prices on the following factors:

      the type of power used - Door garage motor power determines how fast the door garage opens.  It has to have sufficient power to raise open the door garage panels.  Large motors are necessarily needed for large door garages. 

      the speed of the door garage -   A door garage that opens fast with the use of a remote control will cost more.  But for the safety of this type of door garage, it closes slower than it opens.
