Balancing Your Garage Door

A vital first step in making sure your garage door runs smoothly and evenly is to balance it. Not only does an unbalanced door create gaps, but it also puts excessive strain on the system, which can result in early wear and tear. 

To prevent the garage door from being unduly strained or too heavy on one side, balancing entails changing the tension in the springs.

Follow these steps for a comprehensive balancing process:

  1. Locate the Springs: Garage doors typically have either extension or torsion springs, located above the door or on its sides. Identify the type of springs your door has and their location.
  2. Release Automatic Opener: Disconnect the automatic garage door opener to allow for manual operation and prevent any interference during the balancing process.
  3. Close the Door: Lower the garage door to its fully closed position. This serves as the starting point for adjusting the spring tension.
  4. Adjust Torsion Springs: For doors with torsion springs, use a winding bar to adjust the tension. Insert the winding bar into one of the winding cone holes and turn it in the appropriate direction, following the manufacturer’s guidelines. Make incremental adjustments, testing the door’s balance after each turn until it stays in place when lifted halfway.
  5. Adjust Extension Springs: Doors with extension springs will have a safety cable running through them. To adjust tension, pull the safety cable through the adjustable bracket, making sure to maintain an equal amount of tension on both sides.
  6. Test the Balance: Once adjustments are made, manually lift the door to the halfway point and release it. A balanced door should stay in place, neither rising nor falling. If the door moves on its own, further adjustments are needed.
  7. Fine-Tune as Needed: Fine-tune the tension as necessary to achieve perfect balance. It may take a few iterations to get it just right, so be patient and make small adjustments.

Check the Weather Stripping

As a barrier against breezes, rain, and outside factors, weather stripping is essential to preserving the integrity of your garage door. 

A common culprit for gaps you may have seen along the garage door’s sides or bottom is old or torn weather stripping.

Start by visually examining the weather stripping that is currently installed on your garage door’s sides and bottom. 

Check for rips, abrasions, or defects. Weather stripping may become less effective over time due to exposure to various weather conditions and frequent use.

If you find weather stripping that has to be replaced, remove it. Starting at one end and working your way around the perimeter, carefully remove the outdated weather stripping from the door. 

During this process, take care not to harm the door or any nearby surfaces.

After removing the old weather stripping, give the exposed area a quick cleaning. Clear away any dirt, debris, or adhesive residue that has gathered over time. 

When the replacement weather stripping is placed, a clean surface guarantees good adherence and a tight seal.

It’s now time to put in the replacement weather stripping. To guarantee proper installation, consult the manufacturer’s instructions that come with the replacement stripping. 

Certain weather stripping materials may have particular needs, such as location or application methods for the glue.

Make sure the new weather stripping is evenly aligned when you position it along the garage door’s sides and bottom. 

For optimal adherence, press the stripping firmly against the door. Whenever a manufacturer recommends a curing or drying period, adhere to their instructions.

You may be confident that your garage door has new, high-quality weather stripping if you follow these instructions. Consequently, this enhances the integrity of the weather-resistant seal.

Examine and Adjust Tracks

A garage door that sits unevenly and leaves visible gaps is often the result of misaligned or twisted tracks. A thorough inspection and rearranging of the tracks are required to solve this issue.

Follow these steps to inspect and adjust the tracks for optimal alignment:

  1. Use a Level to Check Alignment: Take a carpenter’s level and start evaluating the track alignment. Check for any irregularities by placing the level horizontally along the entire track. You will have to alter the tracks if it is discovered that they are not aligned correctly. With the right tools, find the bolts holding the tracks to the garage door frame and loosen them to provide some wiggle room.
  2. Inspect for Bends or Damage: Look for any obvious bends or damage on the tracks during the alignment inspection. Uneven sitting can be caused by bent tracks, which might interfere with the garage door’s smooth operation. If you find any bends, carefully tap the tracks back into shape using a rubber mallet. To prevent more harm from occurring, proceed with caution when doing this.
  3. Tighten Bolts Securely: After adjusting any bends and lining up the tracks, firmly tighten the nuts. Make sure the tracks are attached to the garage door frame securely. This stage is essential for preserving the proper alignment over time and avoiding gap recurrence. To keep equilibrium, be sure to equally tighten the bolts.

Inspect and Lubricate Rollers

If your garage door has gaps, one possible cause could be worn-out or damaged rollers. Regular inspections and lubrication performed as part of proper maintenance can avert problems and guarantee trouble-free door operation.

Follow these steps to inspect and lubricate the rollers effectively:

  • Inspect Each Roller for Wear or Damage: Start by attentively inspecting each roller to look for indications of deterioration. Because of typical wear and tear or exposure to the environment, rollers may deteriorate over time. Examine them for any anomalies that can impair their performance, such as cracks or flat areas. It’s critical to replace any damaged rollers as soon as possible. The smooth operation of the garage door is facilitated by new, functional rollers that also aid with gap elimination.
  • Apply a Silicone-Based Lubricant: The rollers need to be lubricated after being inspected. For best effects, use a premium silicone-based lubricant. Make sure the oil is evenly distributed by applying it straight to the roller bearings. Because silicone lubricants last longer and are more resilient to temperature fluctuations, they are the favored option. A properly lubricated garage door performs better overall, lowers wear on the rollers, and decreases friction.
