How to Adjust a Patio Door That Has Dropped

A patio door that has dropped can be a major inconvenience, making it difficult to open and close and potentially causing problems with weatherstripping and energy efficiency. Fortunately, adjusting a patio door is a relatively simple task that can be completed in just a few steps. Here's what you'll need to do:

1. Gather Your Tools

You'll need a few basic tools to adjust your patio door:

A Phillips head screwdriver
A flathead screwdriver
A hex key (Allen wrench)
A level

2. Locate the Adjustment Screws

Most patio doors have two adjustment screws, one on the top and one on the bottom. The top screw adjusts the height of the door, while the bottom screw adjusts the angle of the door. Locate the screws on your door and make sure they're accessible.

3. Adjust the Height

Using the Phillips head screwdriver, turn the top adjustment screw clockwise to raise the door or counterclockwise to lower the door. Turn the screw only a quarter turn at a time and check the level of the door after each adjustment. Continue making adjustments until the door is level.

4. Adjust the Angle

Using the flathead screwdriver, turn the bottom adjustment screw clockwise to angle the door inward or counterclockwise to angle the door outward. Turn the screw only a quarter turn at a time and check the angle of the door after each adjustment. Continue making adjustments until the door swings smoothly and closes properly.

5. Tighten the Screws

Once you've made the necessary adjustments, tighten the screws using the hex key. Make sure the screws are tight enough to hold the door in place but not so tight that you damage the door or the frame.

6. Test the Door

Open and close the door several times to make sure it's working properly. If the door is still not functioning as it should, you may need to make further adjustments or call a professional to have the door repaired.
