hi, i have this huge sliding glass door that leads from my bedroom to the balcony. it was working fine till recently, it started squeaking like crazy whenever i slide it open and close. it's a double pane glass door, and it's driving me nuts.

so, how can i get it to stop squeeking? i look on the bottom of the window there's a hole in the front and the back side of the door. is there some kind of adjustment i can do to it to prevent the squeak?

plz help!!

 

The door glides on rollers at the bottom, and sometimes at the top. They may be dirty or are failing, but lubrication is needed as a start. Not something oily that will collect dirt/dust, but something like a teflon spray. Ideally, the door should be removed and the rollers inspected, cleaned, and replaced if needed. Those holes are for access to adjustment screws for leveling the door. They raise/lower the door on the rollers. To remove the door you need to turn the adjustment so the doors is at its' lowest. That usually allows enough room to lift the door up and out of the track. But some manufacturers have a stop molding at the top that also must be removed. And CAUTION, that door is heavy.
