How to Fix a Broken Zipper

A broken zipper can be a frustrating inconvenience, but with a few simple tools and a little patience, you can often repair it yourself. Whether it’s a stuck slider, a separated zipper, or missing teeth, here’s a step-by-step guide on how to fix a broken zipper.

Tools and Materials


First, figure out why the zipper is stuck. Common causes include fabric caught in the teeth or a misaligned slider.

Step 2: Apply Lubrication

If the zipper is stuck due to friction, apply a small amount of wax or soap to the teeth on both sides of the zipper. This should help the slider move more smoothly.

Step 3: Gentle Tug and Wiggle

Gently tug the fabric on either side of the zipper while wiggling the slider. This can help release any fabric caught in the teeth. Be patient and avoid using excessive force, as this can damage the zipper further.

Step 4: Pliers for a Misaligned Slider

If the slider is misaligned, use needle-nose pliers to carefully bend it back into shape. Be cautious not to break or distort the slider.

Repairing a Separated Zipper

Step 1: Re-thread the Zipper

If your zipper has separated, carefully slide the safety pin through the fabric just above the slider. Use it to guide the slider back onto the teeth. Remove the safety pin once the slider is back in place.

Step 2: Zip Slowly

After re-threading the slider, zip up the zipper slowly and evenly to ensure it doesn’t separate again.

Replacing a Zipper Slider

Step 1: Remove the Old Slider

If the slider is damaged and needs replacing, use the needle-nose pliers to remove it. Gently squeeze the bottom of the slider, and it should come off.

Step 2: Attach the New Slider

Slide the new slider onto the teeth. Make sure it’s facing the right direction (the pull tab should be on the outside). Use the pliers to carefully crimp the bottom of the slider to hold it in place.

Step 3: Test the Zipper

Zip and unzip the repaired zipper a few times to ensure it functions properly.

Repairing Fabric Tears

Step 1: Align and Pin

If the fabric around the zipper is torn, align the edges of the tear and pin them together.

Step 2: Hand Sew

Using a needle and thread, hand sew the torn fabric back together. Use small, neat stitches to ensure a secure hold.

Step 3: Trim Excess Thread

After sewing, trim any excess thread and remove the pins.

Additional Tips

  • Prevention: To avoid future zipper issues, be gentle when zipping up and down, and don’t force it if it gets stuck.
  • Regular Maintenance: Periodically lubricate your zippers with wax or soap to keep them functioning smoothly.
  • Professional Help: If your zipper is severely damaged or if you’re unsure about repairing it yourself, consider taking it to a professional tailor or seamstress.
