WHEN IS IT TIME TO HAVE MY DOOR SERVICED 

1. Difficulty Opening or Closing: If the door is sticking, jamming, or not sliding smoothly.

2. Strange Noises: Unusual sounds while opening or closing the door may indicate underlying issues.

3. Drafts or Leaks: If you feel drafts or notice water leaks around the door, it's time for inspection.

4. Visible Damage: Any visible damage to the tracks, rollers, or glass should be addressed promptly.

5. Worn or Broken Hardware: If handles, locks, or other hardware show signs of wear or breakage.

Regular maintenance can also help prevent issues and extend the life of your sliding glass door.
