Tips

Common Mistakes to Avoid

1. Incorrect Wheel Selection

Reason: Using wheels that are the wrong size or type for your sliding glass door can lead to improper alignment and continued sticking or difficulty sliding.
Solution: Measure your existing wheels carefully and purchase exact replacements or consult a hardware specialist for assistance.

2. Forcing the Wheel into Place

Reason: Trying to force a wheel into its track can damage the wheel, the track, or both, potentially requiring more extensive repairs.
Solution: If a wheel is difficult to install, carefully examine the track and wheel for obstructions or misalignments before proceeding.

FAQs

What tools will I need to replace my sliding glass door wheels?
You'll likely only need a screwdriver (Phillips head is most common), and possibly a putty knife to help pry off any stubborn roller covers. Some more modern doors may require additional tools, but a basic toolkit is usually sufficient.
My sliding glass door is still sticking after replacing the wheels. What could be wrong?
Several issues can cause sticking even with new wheels. Check for debris in the track (clean it thoroughly!), ensure the track itself isn't bent or damaged, and verify the wheels are correctly seated and rolling freely. If the problem persists, the door may need adjustment or further inspection.
