Sliding Glass Door French Inserts - 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 soil and debris have clogged up the track of your door panel and the wheels. This is not a hard fix, but because most sliding glass doors are rather heavy, it's best if you have another person present to assist you.
Once the door is on its side, you can carefully analyze the wheels and the track. Most commonly, you will find the wheels are full of debris and soot, and the path is, in addition, probably really dirty. Use compressed air and needle point pliers, to clean the wheels. Be careful to pull every last hair out of the wheel bearings. It is wise to be diligent in this step, which means you don't 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 meets with any other surface of the door frame. A rule of thumb of thumb will be to simply wipe down anything that looks dirty. Don't forget, even if the soil is just not necessarily on the course itself, it can eventually fall to the course causing your door to demand another wipe down.
