How To Adjust Patio Door Hinges

Patio door hinges that are loose or sag can lead to serious problems. For instance, the doorway can drag across the floor, creating scuff marks. A misaligned patio door can also drop since the hinges might not handle the door’s weight and gravity’s pull. So how can you adjust the hinges on a patio door? We consulted DIY and industry experts and here’s what we found.

The correct methods to adjust patio door hinges generally depend on the direction of the misalignment. But these methods often follow similar steps such as the following:

  1. Measure the awkward distance between the leaf and frame.
  2. Remove the plastic covers securing the adjustment screws on the hinges.
  3. Turn the screw clockwise or counterclockwise, depending on the fine-tuning requirements.
  4. Return the plastic covers and test the door’s functionality if it still encounters problems.
