Glass Panel Overhead Garage Doors - As it pertains to maintaining your home in tip-top condition, nothing can be more annoying than a sliding glass door that won't slide. In the end, what's the point of having an attractive glass door that leads out into a scenic backyard if the darn thing takes three NFL linebackers to slide it open?
The number 1 reason why your sliding glass door won't side is because too much soil and debris have clogged up the wheels and the path of your door panel. This is not a hard fix, but it is best if you've got another person present to help you, because most sliding glass doors are quite heavy.
You can closely examine the track and the wheels, after the door is on its side. Most often, you'll find the wheels are filled with soot and debris, as well as the trail can also be likely really grimy. Needle point and use compressed air pliers, to clean the wheels. Be careful to pull every last hair out of the wheel bearings.
While you are at it, clean up all the "mating-borders" of the doorway. This is where the sliding door and some other surface of the door frame meet. A general rule of thumb would be to just wipe down anything that appears filthy. Don't forget, even whenever soil isn't always on the track itself, it can eventually fall to the track causing your door to demand another wipe down.
