The sliding patio door at this Almonte home opens onto a large back deck, so it gets used every day. It had become heavy and rough to slide. The cause was underneath the door: the rollers had rusted and worn out. We took the sliding panel out, replaced the rollers, put the panel back and adjusted it so the door rolls properly again, without replacing the door.
The door before the repair
Rollers fail gradually, so most people get used to a door that is a little harder to open each season until it takes real effort. This clip was filmed when we arrived, opening and closing the door to see how it moved and where it caught.
Taking the panel out
Patio door rollers sit inside the bottom rail of the sliding panel, so the panel has to come out of the frame to replace them. With the stops removed, the panel was lifted off the track and set down on the deck, where the old rollers could be taken out of the bottom rail.

What the old rollers looked like
The old rollers explained everything. The wheels were rusted and worn, the axle and adjustment screw were corroded, and the housing was packed with dirt and debris from years in the track. Wheels in that condition no longer turn freely, so the door slides on them instead of rolling, which is what makes it heavy and noisy.
Next to an old roller, the new one shows what the door should be riding on: clean wheels that spin freely, a straight housing and an adjustment screw that still turns. The adjustment screw matters, because it is how the door is raised or lowered to sit level in the frame.

Putting the door back and adjusting it
With new rollers fitted to the bottom rail, the panel was lifted back into the frame and set on the track. The rollers were then adjusted so the panel sits level, runs straight along the track and closes evenly against the frame and weatherstripping, so the lock lines up with its keeper.

After the new rollers
The second clip was filmed after the repair. The door moves along the track with one hand and closes fully, the way it did when it was new.
Repair before you replace
A patio door that has become hard to slide often does not need replacing. When the frame, glass and seals are in good shape, new rollers and a proper adjustment bring back smooth operation for much less than a new door. It is worth having the door looked at before you price a replacement.
Other things we check while the panel is out: the track for dents or wear, the handle and lock, and the weatherstripping. If the track itself is damaged, see sliding door track repair; for locks and latches, see patio door lock repair.
