If your garage door is still squeaky after applying silicone spray to all the joints, rollers, and hinges, there could be several reasons for the persistent noise:
Lack of Lubrication: While silicone spray is a good lubricant, some garage doors may require a heavier-duty lubricant like lithium grease or white lithium grease. These types of lubricants provide better and longer-lasting lubrication, especially for metal-on-metal parts.
Worn or Damaged Parts: The squeaking could be due to worn or damaged rollers, hinges, or other components. Inspect these parts closely to see if any of them are showing signs of wear, rust, or deformation. If you find damaged parts, they may need replacement.
Track Misalignment: Garage door tracks must be aligned correctly for smooth and quiet operation. If the tracks are misaligned, the garage door may bind, causing friction and squeaking. Check the alignment of the tracks and adjust them if necessary.
Tension Issues: If the garage door springs are not properly adjusted, it can lead to excess strain on the rollers and hinges, causing squeaking. Garage door springs are under high tension, so it's best to have a professional handle adjustments or replacements.
Dirt and Debris: Accumulated dirt, debris, or even insects in the tracks and hinges can interfere with smooth movement and cause noise. Regularly clean the tracks and components to ensure proper operation.
Poor Quality Parts: Sometimes, garage doors come with low-quality components that may not perform well, even with lubrication. In such cases, upgrading to higher-quality rollers and hinges may help reduce the noise.
Weather Conditions: Extreme temperatures or humidity can affect the performance of lubricants and cause squeaking. Consider using lubricants specifically designed for your climate.
Structural Issues: In some cases, the squeaking may be due to structural issues with the garage door or the way it was installed. If you suspect this is the case, it's best to have a professional garage door technician assess the situation.
To troubleshoot the issue, try using a different type of lubricant or a higher-quality product. If the problem persists, consider consulting a professional garage door technician who can thoroughly inspect and diagnose the cause of the squeaking and provide appropriate solutions.
