Broken zipper
Also: stuck zipper · separated zipper · faulty zip
Broken zippers are fasteners that no longer function — a separated slider, missing teeth, a stuck pull, or a zip that splits open after closing. Found on jackets, jeans, and boots, they directly block how a garment is worn and are judged under functional elements on the grade.
How to fix a zipper that is not closing
Short answer: sometimes. It depends on what exactly you have and how long it has been there. The steps below say where it stops working rather than pretending it always does.
- 1Work out which part failed. Nine times in ten it is the slider, not the teeth.
- 2If the teeth separate behind the slider as you zip, the slider has worn open. Squeeze it very gently with pliers, a fraction at a time, and test between squeezes.
- 3If a tooth is bent, straighten it with needle-nose pliers before touching the slider. A bent tooth destroys a new slider immediately.
- 4If the slider has come off entirely, pry off the metal stop at the bottom, feed both sides back through, and crimp the stop back on.
- 5If teeth are missing, the zip is finished. Replacement is the only fix and on most garments it costs more than the garment.
Stopping it happening again
Zip a garment up before washing it. An open zip in a machine is what bends teeth, and it also snags everything else in the drum.
Fix a zipper that will not stay closed
- Difficulty:
- Moderate
- Time:
- About 15 minutes
- Cost:
- Free, or under $5 for a replacement slider
Tools
- Needle-nose pliers
Materials
- Replacement slider, only if crimping fails
1.Work out what actually failed
Zip it and watch. If the teeth separate behind the slider as it passes, the slider has worn open. If a tooth is bent or missing, that is a different problem and the slider is fine.
2.Straighten any bent tooth first
Grip the tooth with needle-nose pliers and ease it back into line. Skipping this destroys a new slider on its first pass.
3.Crimp the slider a fraction at a time
Squeeze the back of the slider gently, top and bottom, and test after every squeeze. Overtightening jams it permanently, and there is no way back from that.
4.Refeed the slider if it came off
Pry the metal stop off the bottom of the zip, feed both tapes back through the slider evenly, run it up to check, then crimp the stop back on.
5.Know when to stop
If teeth are missing rather than bent, the zip is finished. Replacement is the only fix, and on most garments a tailor charges more than the garment is worth.
How to spot it
- Zip the closure fully up and down several times, feeling for catches
- After closing, tug the two sides apart to check the zip doesn't split
- Inspect the teeth or coil for gaps, bends, or a slider that skips
Grade impact
A broken zipper is a Functional Elements (15%) issue and often decisive. A sticky pull that still works stays near Good (6); a zipper that won't close, separates under load, or has lost teeth caps the item at Fair (5) or Poor (3–4) until repaired.
Fixability
Frequently repairable. A new slider, stops, or a full zipper replacement by a tailor restores function, though it's a paid repair. A replaced zipper is non-original and should be disclosed as such.
How to disclose it
Describe the exact failure ('zipper separates at the base when closed'). A broken main closure is a grade-defining flaw, so buyers must know before they pay, not discover it at home.
Broken zipper — frequently asked
- Is a broken zipper worth repairing before resale?
- Often yes. A tailor can replace a slider or the whole zipper, which restores function and lifts the grade out of the Fair or Poor range. Factor the repair cost against the item's value, and disclose that the zipper is a non-original replacement.
What if it does not all come out?
Most of the time some of it stays, and the leftover is what a buyer sees. A garment is worth what its condition says it is worth, so the sensible next question is how much this particular flaw moves the number.
