My Windows Won’t Stay Up – Easy Fix

This is a first in our series of posts on trouble shooting your windows.  We hear from people all the time asking how to address a window problem.  You’ll likely find that many common replacement window problems can be fixed pretty easily.  Here we’re looking at what to do if your windows won’t stay up.

The first step is to take a look at the window itself to see if you can tell what’s going on.  In all double hung replacement windows there are balances in the sides of the frame that support the sash and hold it up when you open it so it doesn’t fall.

We’ve made a quick video that may help to diagnose your problem.

There are only 2 likely scenarios if your windows won’t stay up:

The first one is that one or both of the balances are not connected to the sash.  This would mean that the balances are there and they may be working fine, but they’ve become disconnected from the sash so they are not helping to keep the window open.  In the video above we show you how to address that, it’s typically an easy fix.

The second scenario is that one or both of the balances are connected to the sash, but they are not working properly.  In this case you’ll probably need to replace the failed component.

To do this you’ll need to identify which part has failed.  There are 3 parts that might need to be replaced.

The pivot bar is a small metal bar that is attached to the bottom of the sash.  This bar sticks out of the sash and connects to the balance shoe inside the frame.  If your pivot bar is broken, twisted, or otherwise not engaging with the shoe you should remove it and take it to a local window distributor to see if they have a similar part.

if your windows won't stay open the pivot bar could be the problem.
Here’s a broken pivot bar. Most of this bar is inside the bottom of the sash of the window, the end of it should be visible.

If your pivot bars look good, check the shoes.  The shoes are small plastic or metal blocks that are inside the frame.  They connect the balance in the frame to the pivot bar in the sash.  It is possible that the shoe could be cracked, stuck or otherwise defective causing improper operation.  I you can remove the shoe try taking it to a local distributor to see if they have anything similar.

This is a balance shoe. If your windows won't stay up this might be broken.
This is a balance shoe. You’ll find a part similar to this inside the frames of your double hung windows.

If the pivot bars are looking good and the shoes appear to be in fine shape then your balances themselves must be defective.  There are 3 types of balances, spiral, constant force or coil, and block and tackle.  Be careful when removing the balances as they may be under tension and they could snap out when released.  Balances can typically be removed with just one or two screws.

Once you have the components taken apart it will likely be pretty easy to see what is not working.  If your windows are older or if you don’t know who manufactured them you may have a hard time finding compatible parts.  Many window companies use very similar parts so it’s possible that another company will have something that will work for you, but you may need to try several distributors or manufacturers to find a part that will work.

Unfortunately if you can’t find the right part you might be out of luck and replacing the window may be the only option.  Hopefully this info helps to solve your problem.

    1. Can I fix my single hung window that will not stay up?

    1. That’s old school! The options are to take it apart and try to replace the rope or to get a new window. I guess it depends on how attached you are to those old windows.

  1. My Anderson window will not stay up and windows were put in in 1984 . The sash does not come out and balances are not visible. How can you repair them ?

    1. It might be a bad balance as they’re pretty old. I’d call Andersen. If you can find the serial number sticker in the top of the frame you’ll be in decent shape.

  2. I was cleaning windows this morning and sadly did not look up the Anderson window Youtube how to let the top window out. I asked my husband and he forced it to swing open not realizing there were springs to push open. Now the top window will not stay up and I see two loose springs that came out. Is there a way to put the springs back so that the window will re-engage to stay put?

    1. Sorry to hear about your trouble. You can probably get the pivot bars back in the shoes to get it working right again as long as nothing is broken. You might check with Andersen to see if they have a video or something to show you how to do it.

  3. Hi Dan,
    Great article. We had 18 balancers that needed to be changed. But most we the lower sash.

    There were three windows where the top sash and bottom sash balancers need changing.

    When I put the top sash back in first by itself, the balancer holds fine and everything seems great. But when I push the window all the way up…it stops about 1″ from the top.

    What makes it stranger, all three windows where we replaced the top balancer all stop 1″ from the top.

    Clearly you would think something is blocking it or something is stopping it from going up, but my spouse (she is working on it) claims there is nothing she can find. But it’s the same on all 3 windows so it must be the same thing.

    If you or anyone reading this thread has any thoughts or ideas to try, it would be great. Thanks so much. Hope everyone is enjoying their weekend.


    1. I love problem solving! It could be that something is in the way or it could be that the new balances are too short. Balances are measured in height and strength. You might have balances that are the right strength, but not tall enough. That would allow the window to operate correctly, but not open all the way. You could test this by removing the sashes so they’re disconnected from the balances then try putting them back in the frame and sliding them up while they’re disconnected from the balances. If they go up you know the balance was the issue and if they don’t something is blocking them.

      Good luck!

      1. can you measure the lower sash on a single pivot window to get the balance length needed? or, is there another way to measure for the length of spiral pivot balance length without taking the window open or off. They are heavy and if I get the part, my fixit guy will do the work.

        1. Good question, you can probably get close enough by just measuring the height of the window. Most spiral window balances allowed you to twist the balance to add pressure to it so you only needed the height and not the total weight. That’s a little different than most more modern styles. Now you need t specific the height and the weight as a wider window would be heavier and that would need a stronger balances than a narrow window.

          Good luck with the project. You don’t find too many people repairing old spiral balance windows anymore.

  4. You guys are great. Your video turned what appeared to be voodoo into an easy repair. Saved me some $ by not needing professional help.

    1. Is the sash hooked into the balance shoe on both sides? If so then you probably need one or two new balances. You can likely get them from the manufacturer.

  5. I have new double hung windows. When I raise the bottom one the top one drops down a little. When I close the bottom window and go to lock won’t lock till I hold the top one up tight and push bottom down and lock still having to hold the top one.

    Can you tell me how to fix. If can email would appreciate. The man who put in said that’s way suppose to work but I’ve lived in houses with them before and never had to hold top one up.

    Thank you


    1. Sounds like you need a new balance or two. Do you know who made the windows or who installed them? I’d start there. If you can find the manufacturer it might be an easy problem to solve.

  6. Hi,
    All of our windows seem to not come down all the way to line up with the lock mechanism (they are single hung windows). There seems to be too much tension from the string in the balancer. They are channel balancers. Is there any way to adjust the tension in channel balancers or do they need to be replaced because they didn’t use the right kind from the start? This is 5 yr old house. There is alot of info on adjusting spiral balancers online, but not on channel ones. And if they do need to be replaced, how can I find out which balancer I should buy? We can’t find any local company/person to fix this issue for us, and the window company charges us so much just to come out here. I’d really appreciate any help.

    1. Who made the windows? I’d start by contacting them. There may be a charge for parts or service, but it’ll be easiest to get the right parts if you just order them from the manufacturer.

  7. I didn’t even have to watch the video. Read the article. Inspected my parts and found one of the balances had become disconnected. Three minutes and the window works good as new! Thanks!

  8. Thanks window dog. You came through in the clutch. After watching the video on how to fix your window I was able to fix mine in a matter of minutes. What a relief! Clear, concise, and easy to follow. Thanks again.

  9. Watched your video, have the same issue with my double hung not staying up on the bottom pane. I’m pretty sure it’s the spiral balances, after opening other windows and looking to see what was working. Watching other videos, it shows the casing where the spiral balances are is attached by a screw at the top. In my windows, the top has about a 3 inch plastic piece sealed and attached to the frame, so I cannot access the top of the spiral. Does this mean I can’t change it myself?

    1. I would guess there’s a way to do it. Spiral balances are a huge pain in the butt. You may able to disconnect it at the bottom and twist it several times to give it more tension. Just be really careful if you try that as it could easily bite you.

    2. Thx for the reply! The spiral did disconnect at the bottom- that’s the issue. Looking at a working window, I see some sort of red piece attached to the spiral, guessing that’s the balance that popped off?

  10. I’ve been replacing broken coil supports on our windows and have come across two different assemblies. All the windows have two coils on each side. Some have the top coil locking into a hole on the bottom coil and the bottom coil locking into the shoe, while others have both the top and bottom coils locking directly into the shoe. Does this difference matter?

    1. They’re probably 2 different types because of the size of the windows. Larger or heavier windows will need more support to stay up. So, one way isn’t better than the other, just a larger balance to hold up a heavier sash.

  11. Oww.. Thanks for sharing this lovely post. Wondering about the best suitable windows well cover? No worries! This is the right place. This content is able to disclose all related questions and answers. When you have a basement, it may want enough windows or doors to play with natural light. To ensure the natural lighting entrance, you have to set a proper well cover.

  12. I have alside triple pane windows, one of the balancers broke and was replaced top sash! now the top sash drops down 1/4 inch not allowing the locks to line up? if pushed back up it will remain in place long enough to lock window. I don’t remember this window ever being like this?

    1. Hi Nick, I would bet the sash didn’t get put back in correctly. Did you watch the video on this page? There’s a decent chance the solution is in there. If not there’s a chance you have the wrong balance in there, but that’s less likely.

      1. Thanks for the prompt reply! Yes I did watch the video! Both balance devices are in place and appear to be properly attached? If I “slam” the window up it stays up and when lowering it the balance devices are working properly. As in they hold the window up from the first movement down?

        1. Next move would be to confirm that it has the correct balances. The company that replaced them should be able to tell you which balances they should have. Each will have a number and maybe a letter, like 7C. That tells you how far they can open and how strong they are. I’ve seen windows with incorrect balances before so that might be it.

          1. I finally got it figured out! one of the balance devices were replaced, with the correct unit. being these were dual spring devices (with triple pane windows) The inital tension on the springs had weakened to the point they could not hold the top sash up at the end of the spring tension when fully wound up. My repair was to remove the two screws centered in the springs and re locate both springs up to utilize the upper spring mounting to attach the lower spring. Up about 1 inch from original location.
            Now with the sash lubricated (with enddust) the window works better that when new!!
