Sliding Glass Door Threshold Cover - When it comes to maintaining your home in tip top shape, nothing can be more annoying than a sliding glass door that won't slide.
The number 1 reason why your sliding glass door won't side is because too much dirt and debris have clogged up the wheels and the course of your door panel. This is not a hard fix, but because sliding glass doors are rather heavy, it's best if you have another person present to help you. The first step would be to analyze your sliding glass door is fixed to the trail.
You'll be able to carefully analyze the track as well as the wheels, once the door is on its side. Most commonly, you will discover the wheels are full of debris and soot, as well as the path can also be probably really filthy. Use compressed air and needle tip pliers to clean the wheels. Be careful to pull every last hair from the wheel bearings. It is best to be diligent in this step, so you do not have to make a habit of this process.
While you're at it, clean up all the "mating-edges" of the doorway. This can be where the sliding door meets with any other surface of the door frame. A general rule of thumb would be to just wipe down anything that appears dirty. Don't forget, even if the dirt is just not necessarily on the trail itself, it may fall to the trail causing your door to need another wipe down.
