Signs it's time to replace your slider
- It sticks, jumps the track or takes two hands to open
- Fogging or condensation between the glass panes
- Drafts, dust or water coming in at the bottom track
- The lock doesn't line up or doesn't latch
- Single-pane glass or a heavily pitted aluminum frame
Can't I just replace the rollers?
If the frame is straight and the glass is sound, new rollers and a track repair can buy a few years. When the seal has failed, the frame is bent or corroded, or the door is single-pane, replacement is the better investment.
