Stained Glass Double Entry Doors - In regards to maintaining your house in tip-top shape, nothing can be more annoying than a sliding glass door that won't slide.
The number 1 reason your sliding glass door won't side is because too much soil and debris have clogged the course of your door panel and the wheels up. It is best if you have another person present to assist you, because most sliding glass doors are rather heavy, although this really is not a difficult fix.
You are able to carefully examine the track as well as the wheels, after the door is on its side. Most often, you will find the wheels are filled with debris and soot, as well as the course is, in addition, likely quite grimy. Use compressed air and needle point pliers to clean the wheels. Take care to pull every last hair out from the wheel bearings. It's wise to be diligent in this measure, and therefore you do not have to make a habit of this process.
While you're at it, clean up all the "mating-edges" of the door. This is where the sliding door and some other surface of the door frame meet. A general rule of thumb is always to simply wipe down anything that seems filthy. Remember, even whenever soil is not necessarily on the trail itself, it may fall to the track causing your door to demand another wipe down.
