To slide the heavy doors along the metal frames the doors use metal or plastic rollers.
Sliding patio door track fills with water.
Water can seep through even the smallest cracks.
Check to see which door moves and which one is the stationary.
Have a reputable sliding door contractor remove the door if it has not been damaged build a new frame and reinstall the door.
This is a three panel horizontal sliding window.
Any thoughts on how to fix this.
The track on the sliding glass door should have a weep hole drain hole on each end to drain the water out of the track.
Last night we had heavy winds with the rain which blew it against the door and the tracks filled to overflowing quickly even though the rain wasn t all that heavy.
These holes are normally in the outside corners of the tracks.
If the sliding glass door is placed directly on a pre existing concrete slab with no recessed area in which the door track can lay water can penetrate the home s interior flooring through the bottom of the threshold if there is a breach in old caulking.
The weep holes seem present and unblocked.
Look for dirt or debris that could be clogging these holes.
Damage to the door itself.
If you have a problem with water leaking it will usually be on the bottom track threshold of the non stationary door.
If a frame is crooked water can leak into the gaps between door and frame.
The water seems to be filling the window tracks then entering.
It is likely that one or both of these weep holes are clogged.
I am adding a photo of the window tracks.
