3 Issues That Prevent Your Garage Door From Closing Evenly

Construction & Contractors Articles

If you're winterizing your home, then you know that you have to do something about that uneven gap beneath your garage door. In an attempt to fix this issue, you may have already replaced your bottom panel's weatherstripping or inspected your lower panel for potential damage from your vehicle. Unfortunately, there are several issues that can cause your garage door to close unevenly. Determine which of these three issues are causing your uneven gap and perform or arrange for the necessary repairs:

Poorly-Maintained Counterbalance System

If you didn't install your garage door assembly, then it's likely that you're unfamiliar with your counterbalance system.

Your counterbalance system is the series of drums, cables, and springs just above your garage door opening. This system uses torsion created by your springs to lift the majority of your door's weight whenever you open your door. Additionally, it mitigates the weight of your door while you close your door to prevent your lower panel from slamming into the ground.

If you're unfamiliar with your counterbalance system, then chances are that you also don't know how to maintain it. Your counterbalance system can become worn or misaligned in a number of ways:

  • Worn Springs

    • Your torsion or extension springs are only expected to last somewhere between 10,000 to 20,000 cycles. If you've exceeded the expected cycle limit of your specific springs, then it's possible that one of your springs has sustained greater wear than the other—causing it to put less tension on the corresponding cable.

  • Slipped Drum or Spring

    • The alignment of your drums and springs is crucial to your door's cycling process. However, since your drums and cables are tightened into your counterbalance system's rotating shaft, they can easily slip and become misaligned.

Counterbalance issues are the most common causes of an uneven garage door. However, performing the maintenance or repairs required to fix these issues is extremely dangerous. Your garage door springs (regardless of whether they're torsion or extension springs) are dangerous to handle due to their tension levels. If you determine that your counterbalance system is the culprit, then have a professional garage door technician perform the necessary adjustments or repairs.

Seized Roller

Your rollers become seized when their bearings become filled with debris that settles in your guide track over the years. When your rollers glide along your track, they'll pick up loose debris such as pet fur, dust, and dirt. In addition to debris, your rollers can become seized when they aren't regularly lubricated. Luckily, seized rollers are easy to detect since they'll produce excessive noise as they scrape along your tracks.

To fix a seized roller, remove it from your guide track. To do so, disconnect your automatic opener and partially open your garage door. Clamp a locking pair of vice grips under a roller on each side of your track. Pry open the section of track just above your seized roller with a flat screwdriver and remove the hinge bolts that secure your roller.

Next, slide your flat screwdriver between the internal wall of your track and your seized roller. Push your roller towards the center of your door and pull it through the opened section of your track. Pull your roller out from the frame of your hinge to finish removing it.

Apply a generous amount of degreaser to your roller's bearings and let it soften any debris inside the bearing cage. Use an air compressor to force the softened debris out of the bearings. If your roller doesn't have any exposed bearings, then it should be replaced instead of cleaned. To reinstall the roller, simply reverse the steps you took while removing it.

Damaged Guide Track

If you've managed to scrape your vehicle's bumper against one of your guide tracks, then you may have bent the track out of position. In such a case, the rollers that glide through the damaged track may have to travel a further distance than the rollers on the other side of your door before they can reach their closed position.

To fix this issue, use a rubber mallet, hammer, or vice grips to bend your guide track back into its original shape. Use the undamaged track on the opposite side of your door as a reference.

If you have trouble repairing a seized roller or guide track, or if you're unable to identify the issue that's preventing your door from closing evenly, then leave the necessary repairs to a professional garage door technician from a company like American Eagle Garage Door Services. If you attempt to perform a repair without knowing exactly what to do, or if you begin tinkering with random parts of your assembly while searching for a potential issue, then you will cause further damage to your garage door.
