Understanding the Causes of Gaps

Weather Stripping

One of the primary causes of garage door gaps is worn or damaged weather stripping. Weather stripping serves to seal the gaps between the door panels and the frame preventing drafts and moisture from entering the garage.

Over time weather stripping can deteriorate due to exposure to harsh weather conditions leading to gaps.

Track Misalignment

Another common culprit behind garage door gaps is track misalignment. The tracks guide the door as it opens and closes, ensuring smooth operation. If the tracks are misaligned, it can cause the door to sit unevenly, resulting in gaps along one side.

Spring Tension Issues

  • Garage doors rely on springs to counterbalance the weight of the door and facilitate smooth operation.
  • If the springs are worn or improperly tensioned, it can cause the door to sag on one side creating a noticeable gap.

Structural Problems

In some cases gaps on one side of garage door may be indicative of underlying structural issues with door or the surrounding framework. This could include issues such as a warped door panel or misaligned door frame.

Assessing the Severity of the Gap

Before attempting any repairs it’s essential to assess the severity of gap. Minor gaps may be addressed through simple DIY fixes while more significant gaps may require professional intervention.

Adjust the Tracks for a Binding or Sticking Garage Door

    • Begin by visually inspecting the tracks for any obstructions or debris that may be causing the door to bind or stick.
    • Clear away any dirt, debris, or rust buildup that could be interfering with the smooth movement of the door.
  2. Loosen the Track Bolts

    • This will allow you to adjust the position of the tracks to ensure they are properly aligned.
  3. Check for Alignment
    • With the bolts loosened, carefully examine the alignment of the tracks. They should be parallel to each other and have a slight downward slope towards the back of the garage.
    • Adjust the position of the tracks as needed to achieve proper alignment.
  4. Use a Level:
    • Place a level along the length of each track to ensure they are perfectly horizontal. Adjust the tracks like necessary to eliminate any unevenness that could cause the door to bind or stick
  5. Tighten the Track Bolts
    • Once the tracks are properly aligned, tighten the bolts securely to lock them in place. Be sure not to overtighten the bolts as this could cause damage to the tracks or mounting brackets
  6. Test the Door
    • With the tracks adjusted and secured, test the operation of garage door to ensure it moves smoothly along tracks without binding or sticking. Open and close the door several times to confirm that the issue has been resolved.
  7. Lubricate Moving Parts.
    • Finally, apply lubricant to the rollers, hinges, and other moving parts of the garage door to ensure smooth operation.
    • This will help prevent future binding or sticking issues and prolong the life of your garage door system.

By following these steps, you can effectively adjust the tracks of your garage door to fix any binding or sticking issues and ensure smooth trouble free operation.
