Assessing the Severity of the Damage

Before diving into the repair process, it’s crucial to assess the severity of the damage to your garage door. Follow these steps to evaluate the extent of the issue:

  3. Measurements: Using a tape measure, check the alignment of the tracks and ensure they are parallel. Measure the gaps between the door and the frame on both sides to identify any unevenness.
  4. Evaluate functionality: Test the garage door’s safety features, such as the auto-reverse mechanism, to ensure they are functioning correctly. Check if the door stops and reverses when it encounters an obstruction.
  5. Seek professional opinion: If you are uncertain about the severity of the damage or lack the necessary expertise, consider consulting a professional garage door technician for an assessment.

how to fix a loose door handle without visible screws

You can remove the inside door handle to access the screws that hold the door handle assembly together. Use a small tool like an awl to depress the spring-loaded button on the base of the inside handle.

This will allow you to detach the handle. Remove the interior trim ring by unscrewing it, which will expose the screws securing the door handle assembly. Tighten the screws, then reassemble the trim ring and interior door handle.

Alternatively, you may be able to pry off the interior rosette plate gently with a knife. This decorative disk covers the base of the handle and screws. With the rosette removed you’ll be able to access and tighten the screws holding the interior and exterior handles together through the door. Once tightened, just click the rosette cover back into place over the handle base.
