The appropriate skills and tools are required to repair garage doors. There are two components that have to be considered which include the opener and the main flap. In addition, the springs must be in good working condition with the proper tension or power. The other smaller parts should not be neglected. For example a faulty pair of hinges can completely reduce functionality because it means that the panels will not hold together or bend properly.
On the other hand the use of modern electronics presents an entirely different set of problems when repairing a garage door. For example the beams that are critical for the remote control to work accurately may be out of synch or completely dead. There have been instances where the remote was actually controlling a neighboring garage door. The upshot is that all repairs and fixes have to be done as a comprehensive exercise that tackles virtually every aspect of the garage door.
