How to Repair Your Sliding Door
Go from stuck to smooth in eight steps
After years of use, you may find that your sliding patio door is no longer working—or looking—the way it’s supposed to. Maybe it often gets stuck, or the screen is sagging hopelessly. The good news is that unless there’s an underlying structural issue, these problems can be addressed without much difficulty. Dirty rollers from debris in the track are the main culprit for uncooperative sliding doors, and wrinkly screens can easily be replaced.
For a quick tune-up of your patio door, follow the steps below. In just a couple of hours, you can have your old door sliding like new.
Step 1: Lower the door
Lay a drop cloth on the floor and pop off the two plugs covering the roller adjustment screws at the bottom of the sliding-door frame. These are sometimes located in the edges of the door.
Insert a flathead screwdriver into each hole and turn the screw counterclockwise all the way. This retracts the rollers, lowering the door.
