🛑 Before You Spend Money — Try These First

If your door is sticking, scraping, or hard to open — don’t panic. You may be able to fix it yourself with a few tools and 30 minutes.

Here are the 3 most common DIY fixes for sliding glass door issues.

🔧 1. Clean the Track Thoroughly
  • Vacuum dirt and debris

  • Scrub with soap and a toothbrush

  • Dry fully

  • Apply silicone spray (not WD-40!)

🛑 Still sticky? The problem may be inside the rollers.

🔧 2. Tighten the Adjustment Screws

Look at the bottom corners of the door. You’ll find a hole with a small screw that adjusts roller height.

  • Turn right to lift door

  • Turn left to lower
    This helps with dragging or uneven sliding.

🔧 3. Realign the Door

If the frame is slightly shifted, the lock won’t line up. Lift the door slightly while adjusting the rollers — this may bring it back into position.

🚨 When to Call a Pro

If your door:

  • Still doesn’t glide

  • Makes loud grinding noises

  • Jumps off the track

Then it’s time to call Alonso Sliding Door Repair. We can fix it same-day with high-quality parts.
