How to replace patio door rollers step by step?

Here’s the process:

1. Remove the door –

Place it carefully on a padded surface to avoid scratches.

They are usually held in place by screws on the bottom edge of the door.

4. Unscrew and remove old rollers – 

Take out the screws and gently slide the rollers out.

5. Clean the track and frame – 

Vacuum dirt and debris to ensure smooth movement.

6. Install new rollers – 

Slide the replacement rollers into place and secure them with screws.

Use the adjustment screw to align the door so it glides smoothly and seals properly.

For most homeowners, the process takes about 30–60 minutes. If it’s your first time, allow extra time for careful handling.

Can I replace patio door rollers myself, or should I hire a professional?
