How To Replace a Zipper in a Jacket or Coat

If you read my last post on How Much To Charge To Replace a Zipper, I promised I’d be back to show you how to put in a new zipper.

Here’s the jacket with the broken zipper:

The zipper teeth didn’t hold together when the jacket was zipped:

Before you begin, be sure and choose a zipper that is long enough for the jacket opening.

Try to buy a zipper that is the same length as the current zipper.

If that is not possible, get one that is longer.

You can always shorten the top of the zipper.

Here are two different types of jacket zippers:

The zipper on the left is a heavy duty silver metal zipper.

The one on the right is made of durable nylon.

For this jacket, the metal zipper was chosen.

Before you buy the zipper, zip it up and down several times to make sure it doesn’t stick and that it actually works.

You’d hate to sew it in and find out it was defective.

You’d only do that once!

If your zipper tape is wrinkled, you could iron it, but be careful that you don’t hit the teeth on the nylon zippers with the hot iron.

I don’t usually have that problem with jacket zippers.

But occasionally, a dress or pant zipper is wrinkled.

Let’s begin.

I start by grabbing my seam ripper and pulling out the stitches just below the zipper:

Pull out all of the stitches on both sides of the jacket.

As you can see, there is another row of stitching right next to the zipper tape.

It needs to come out too:

Here is what this jacket looks like as the zipper is being taken out.

I think it’s funny that the manufacturer used pink thread:

Here’s another look… near a snap:

I’ll show you how to deal with the snap in a moment.

Before I take the zipper out of the top edge of the jacket, I pay attention to any detail I need to, so that I can put the new zipper back in the same way, if possible.

The zipper tape at the top is usually folded back inside the jacket so it doesn’t show from the outside.

You can’t see that on this jacket, but just take mental notes as you disassemble the area:

Once you take out the entire zipper, be sure to take out all the loose little threads.

Sometimes, a lint roller is very helpful with this stage:

sewing blog 1413

I insert the zipper making sure the correct side of the zipper is on the corresponding correct side of the jacket and pin it every couple of inches:

sewing blog 1414

I like to pin because it anchors the zipper down enough so it doesn’t move as I sew.

If you are uncomfortable doing this, you can always hand baste the zipper in place.

Be sure to pin or baste the zipper so that the teeth won’t get caught in the fold of the fabric edge when you zip it.

I don’t measure this. I just eyeball it and give it about an eighth of an inch clearance.

Make sure that the lining of the jacket is lined up correctly to before you pin or baste.

You don’t want that bunched up at all.

Now, let’s talk about the snaps, if you have them.

When you get to a snap, you may notice that the zipper tape doesn’t fit down into the “hole” too well.

The snap is in the way.

Do you see how the zipper tape rises too high because of the snap?

I place a pin right next to the snap on the zipper tape (see photo below).

It doesn’t have to be perfect placement as you’ll see in a moment.

You just want a visual marker:

Next, with a pair of scissors, notch out a little semi circle on the zipper tape just below your pin, like this:

sewing blog 1421

That semi circle is going to fit over the top of the snap.

Now, remove that pin.

It has done its job.

Place the zipper tape back in the hole and continue pinning:

See how slick that looks?

sewing blog 1422

Your zipper will not pull out because you have that notch.

Trust me on this!

Once the entire zipper is pinned in, put your zipper foot onto your sewing machine.

I also use a denim weight needle.

They are better suited to a jacket than an all purpose needle.

Begin stitching.

Stitch on the stitching line where the original zipper was, being careful not to run over your pins.

Take them out just before you get to them:

sewing blog 1415

When you get to a snap, just stay on course.

You shouldn’t have any trouble staying on the original stitching line.

sewing blog 1423

You might think from the photo above that there would be a small pucker.

To avoid that, I just make sure to hold it tightly as I sew.

Let’s look at how that stitching line looks near the snap:

sewing blog 1424

When you reach the bottom of the zipper, you’ll notice that the zipper tape has a thick, stiff area about one inch long.

I go slowly over this area.

sewing blog 1416

Sometimes, I may even “walk” my needle over the stiff area so that I don’t break my needle.

You may have noticed that the original zipper ended a few inches above the bottom edge of the jacket:

sewing blog 1412

The new zipper was longer and it fit perfectly into the bottom of the jacket:

sewing blog 1417

If your zipper is too long, just fold the excess under at the top.

If it is several inches too long, leave about an inch or more so you can fold it under at the top.

Some people don’t like any bulk from the zipper, so they cut it off.

If you do that, just make sure you have some extra so you don’t have a raw edge at the top.

You may need to whip stitch the top zipper teeth so that the zipper slide (or pull) doesn’t come off.

You don’t need to worry about that second line of stitching that was next to the zipper tape.

This one row will hold your zipper in tightly.

Here is the finished zipper:

I know you’ll have great success too!

  1. Yes! I love it when I do it the way you do it! Almost makes me feel like I know what I’m doing. ;) Except I’m absolutely in love with the way you got around the snap instead of taking it out. SO much faster and easier!

    Oh and yes – definitely check the zippers! After needing 12 zippers for Christmas costumes and not checking any, we ended up having to take costumes up and over heads because they stuck so bad. *Check the zippers before you buy them!*

    Thank you!

    • Of course you know what you’re doing! You’re a great seamstress! Glad you liked the “getting around the snap” trick. No one knows you’ve done it and it’s the original sewing line, so it looks like it was never replaced!

      I’m sorry about those zippers on your costumes, but you had a good idea to make them work. In those situations, you just gotta do what you gotta do!

      Thanks Theresa! Linda

  2. Thanks for being so completely understandable in your explanation! I’ve done this a few times..praying all the way…and had good success. It is not my most favorite repair to do, but in the end, it always looks great and functions well. And thanks for the tip about checking the zippers before buying/installing! I’ve never had a problem before so I will be sure to put that on my checklist as a preparatory step! I can’t imagine going through everything to find an installed zipper that doesn’t work! Again, keep up the good work and keep the tips coming!

  3. Thnaks for the tutorial. Do you have any hints on how to avoid ripple effect on fleece type jackets. It seems no matter how careful I am at removing the old one when I finish putting the new in, it doesn’t lay flat, I have assumed its because it was stretched when taking out the old one. Thanks, Darcy

    • Like Darcy, I too struggle with unpicking zips from fleece – the fleece seems to expand having been unpicked and looks awful and misshapen! I no longer unpick the zips from fleece jackets I just cut them out REALLY carefully and close to the fabric. The end result doesn’t conceal the new zip in between the fabric, so is not as neat as I would like, but it is perfectly functional and you can’t tell from the outside!

  4. Thank you! I’ve been looking forward to this tutorial. I’m off to tackle my husband’s ancient windbreaker & it’s broken zipper. He’ll be thrilled to be able to wear it for another 30 years!

  5. I found your site this morning and can’t wait to have time to go through it entirely. I do a lot of zipper repair. I always prefer repair to replacement if possible. In the case of this example zipper a new tab/pull/slide would have solved the problem. Any time a zipper comes apart behind the tab it indicates that the tab has been stressed to the point that at least one side of the front and back of the tab are no longer perfectly parallel. You can buy metal top stops that just squeeze on to replace the top stop you remove in order to get the damaged slide off. They come in corresponding sizes to the size of the zipper you are working on. They are much quicker than creating a top stop with a needle and thread.

    • Thanks Nikki. (Now you tell me!!! Ha.) This is good to know. I appreciate it.

    • I have also found it is a good idea to replace the slider if the zipper teeth will not come together. Another trick I discovered is to very gently, (and I mean gently) with a pair of pliers, squeeze on the parallel side of the slider. You can’t even tell you have pinched it. It only takes a very tiny squeeze and sometimes the zipper teeth will close. You are right when you say the slider gets stressed. If the squeeze method doesn’t solve the problem then I replace the slider.

  6. I have run into jackets where the snap is positioned directly over the zipper tape and am unable to remove the zipper because the snap is fitting so tightly. What would you do in that situation? Cut out the zipper around the snap? It then would be very bulky trying to fit a new zipper around the snap using the semi circle cut out on the new zipper tape.

  7. I want to thank you very much for your clear, correctly spelled tutorial on how to replace zippers. What a help it has been to me! And seriously, not having to interpret misspellings has enabled me to understand your directions that much faster. You are very appreciated.

    • I haven’t had that kind of a compliment before, but I’m thrilled to get it. Thanks! I try to prrofread each post before I publish it, so I’m glad you liked it. I hope you like the other tutorials I’ve written and find them helpful as well.

  8. After reading your instructions I felt confident enough to replace the zipper in my husband’s 15 year old goose down parka. Keep in mind we live in Arkansas and he probably wore it 2 weeks a year, but during those two weeks it’s a life saver. It is hard to justify spending money on a new one. I learned-
    -If it is a down filled coat, sew a seam along the zipper to contain the feathers as you rip out the zipper.
    -You CAN use a seam ripper “up side down”, putting the little ball end inside the seam so you don’t poke holes or rip the fabric by mistake.
    -If the snaps are too close to the zipper, don’t rip out the old zipper. Just cut off the teeth, seal the cut edge with Fray Check or the like, and sew the new zipper to the old tape. (I define “To Close” as less than the width of your zipper foot’s ability to pass between the teeth and the nub of the snap. I have a new machine with the snap on type foot and is almost 3/4″ wide! The old machine who’s zipper foot would have fit, needs repair.)
    -Since I had ripped out the zipper when I found the zipper foot problem I sewed a 3-sided box around the snap, not catching the zipper at all, and then used Amazing E-6000 to adhere the snap to the tape since there was a little pocket created by the box.
    Well it is 29*, ice on the roads, and my husband HAD to work today. I fixed it last night so I asked him to be gentle on the snaps today until the glue fully set up.
    Your instructions were very clear. I just ran into some educational situations!

  9. Thank you so much for these post:)
    I’m confused about the zipper. Can we just use any type of zipper or there are special zipper for jackets? Since we have to split it half?
    Thanks.

    • Good question. Yes, you need what’s called a separating zipper.” Some people call them a jacket zipper. It is found in the same place that regular zippers are found at your local fabric store. A regular zipper is used on a dress or a pair of pants, for example, and when you unzip it, the garment stays as one unit. A jacket needs to separate so that you can put it on. I hope that makes sense.

    • Hi, Anonymous. I just replaced three jacket zippers in the last two weeks and I can speak only from my experience. I had three jackets- two were fleece jackets without a lining (one adult and one toddler sized) and the other one was a fully lined adult sized down jacket. Each jacket already had a full length broken zipper in them to start with. I chose to measure each jacket and purchase for the adult ones something called a “parka” zipper that has dual separating sliders. For the toddler’s jacket I chose a “parka” zipper that had one single slier on it. I purchased all of them at three separate times, but was able to use a coupon for “40% off one regularly priced item” at Joann Fabrics. Just my experience.

  10. This is awesome! I am gonna try this and will let you know how it goes. Thank you!

  11. so many times after I’ve sewn in both sides I find one side of the jacket is longer than the other, like about a half a inch. I always leave the zipper zipped up when sewing it on to each side, but don’t understand why one side of the jacket ends up longer. HELP.

    • Good question. Try basting the zipper with stitches that are not too long or far apart. It may be that your fabric is moving too much as you sew the zipper in. Also, try to sew in the same direction. If you put one side of the zipper in from top to bottom, do the other side in the same direction: top to bottom (or vice versa).

    • Zip up the zipper after having sewn in the one side of the zipper. I usually start with the slider side of the zipper. Once the side is installed then zip up the zipper and if there are any horizontal stitching on the garment where you need to line up the eaist or something then take your scissors and make a small snip on the zipper tape to line up with the horizontal lines of the jacket. When you pin or baste make sure the snip is lined up exactly with the horizontal stitching. If it gets off a hair then it will show when finished. Be very exact about this and sew the other half of the zipper to the garment. It should come out perfect every time.

  12. Hello I just finished repairing my brothers jacket zipper. I replaced a nylon zipper with a metal one. I was so frustrated because after I sewed the zipper tape in, the zipper kind of curled or puckered and now the zipper won’t zip smoothly. I started another jacket which is a thin fleece and the same thing. Why is this happening?

    • Sometimes this happens when your machine pushes the zipper as you sew and if you sew the opposite direction on the other tape, it will do what you’re talking about. The fix is to take it out again and baste it down good with hand stitches (not just pinning) before you machine stitch. Fleece is a fabric that will move on you a lot, so it’s really important for fleece to baste it. Hope that helps!

      • I have found that using a glue stick to temporarily hold zipper in place in combination with Clover clips for added hold worked wonderfully for stretchy fabric jackets.

  13. You are a Godsend! Once upon a time, I sewed. A lot. Costumes, couture, curtains, and a whole lot of other fun projects. However, I went back to college and became a teacher. While I love my job, I really haven’t had much time to sew. I’m now getting back into it. Of course my first project was hemming a bridesmaid’s dress. Hemming turned into “Oh, I can’t zip up my dress, none of us can! Enter your amazing blog! I read your instructions through, and just did it! You can’t tell the dress was altered that much unless you really look at it! THANK YOU! THANK YOU! THANK YOU!

    • Susan, I am sooo happy to hear about your success! Thank you for letting me know. I’m glad the blog has helped you as you transition back into sewing.

  14. in purchasing a coat or jacket zipper I learned you need to buy
    open face or the coat zipper that cost more but it’s better than a new coat or jacket

  15. I am taking all of the advice in as I have been designated to sew zippers into coats at work though I am not experienced at this. I really need all the help I can get ie hints and tips. Thank-you very much for your information.
