Learning the major components of your garage door is not only helpful when you are inspecting your garage door, but also when you need to identify what could be going wrong (especially when you call us with questions). 

Here's a quick list of the major garage door parts and the maintenance and service they typically need.

  1. Door Sections: Ideally the sections of your garage door are in perfect condition, but we are well aware that life (and car bumpers, baseballs, and bicycles) happens. Some dents do not impact the door's operation, and sometimes they do. 
  2. Hinges: Hinges connect the sections of the door to each other and allow the door to bend as it travels the track. Hinges require lubrication, and can crack, break, and loosen over time and use. 
  3. Sensors: Photo eye safety sensors are located on either side of the garage door near the floor. They work properly when one sensor emit a laser while the other receives it; if the line of the laser is interrupted, the garage door will not (should not) go down. 
  4. Tracks: The tracks are the guides on either side of the door which allow its rollers to glide up and over to your the garage ceiling. Tracks require special lubrication as well and should be kept free of dust, leaves, and other debris.
  5. Spring: The torsion spring, the heavily coiled piece directly above the garage door is under a considerable amount of tension; it's the reason your garage door opener can lift your extremely heavy door. If a torsion spring breaks or makes noise, do not attempt to fix or adjust it. Springs are best left to a professional.
  6. Opener: Automatic garage door openers have more safety features than ever, and can now be controlled and monitored in many different ways: directly from your car, your smart phone, your computer, or the opener itself.
  7. Bottom Seal: Your garage door's bottom seal performs several duties, from protecting your garage against the elements to providing a proper fit for your door. Over time, your bottom seal can become loose, brittle, or degraded. Luckily, a bottom seal can be replaced without needing to replace your whole garage door. 

Now that you know all the major components of your garage door, is it time to do a full inspection?
