How Do You Know It’s Time for New Sliding Doors?

[tofow]

Hello everyone.

I’ve noticed that my sliding doors are becoming harder to open and close smoothly, and some visible gaps are letting in drafts. I’m wondering about the general lifespan of these doors and what signs indicate it’s time for an upgrade.

For those who’ve dealt with old or damaged doors, what are the warning signals you noticed? Specifically, I’m trying to figure out when should you replace sliding doors rather than attempt minor repairs.

Are there safety, energy efficiency, or aesthetic considerations I should keep in mind before making a decision?
