How to Close a Stuck Window

Many people have trouble closing a stuck window. It can be frustrating and difficult to find the right technique for getting them closed. The following article will give you some helpful tips for how to close a stuck window, as well as offer some general advice for preventing this problem altogether. 

How to Close a Stuck Window

10 Common Reasons Why Your Window Is Stuck:

1. Multiple Coats of Paint on the Window:

Older windows are notorious for having multiple layers of paint seal. This causes the vinyl window to stick because it is too stiff to open or close easily. When this happens, the paint seal is stripped from the window and a new layer of paint seal is added. Then, the window should operate more smoothly.

2. Neglect:

Sticky windows can also happen if they’ve sat unused for a long period of time. They rust internally and become stuck over time, even if they were working properly before sitting in the garage. The rust can also cause the window to rattle and sound louder than it should.

3. Plastic or Vinyl Sticky Strips:  

Plastic sheets and vinyl sticky strips are often installed to help close windows with broken hardware, but they can actually cause more problems than they solve. The same is true of cracked sliders that have been repaired with super glue. They’ll keep the window sashes closed, but they’ll also stop it from opening and closing altogether. 

4. Stripping Problems:  

Sticky windows may happen if the stripping around the wooden window is not properly secured to the frame. If you have a metal or wooden frame, check to see if some of the screws are missing. These pieces need to be fully installed so that they keep the window track sealed properly. 

5. Broken Pulleys on the Window:  

If you have a window that won’t open, and you can see the pulley system inside, but it is broken, then this may be your problem. If the pulley inside is broken and cannot move, then the window will not open. The only way to fix this is to replace the entire pulley system, which can be expensive.

6. A Catch on the Window’s Latch:  

You should also check to make sure there are latches on both sides of your window lock and that they move freely. Often, one side of the window shut sticks, and this can cause a problem. After you’ve opened it, check to make sure that the other latch can still move freely. If it can’t, you’ll need to replace the lock. Take a couple of minutes and check your window locks. It will save you a lot of money and heartache in the long run.

7. Slider/Pleated Windows:  

One of the most common problems with slider windows is that they are not properly sealed. Your slider windows will last longer if you make sure to install the plastic channel completely around the frame. This helps prevent drafts and seepage, leading to condensation and other issues that make windows sticky. 

8. Leaky Windows:  

If your window is stuck in one position but opens partially when you tip it up, then it’s likely water is affecting it. Put a towel beneath the window to help absorb any moisture getting in and causing the frame to swell up and stick. If your window isn’t opening at all, there is probably no wood left that can be salvaged and it needs to be replaced.

9. Humidity Moisture Impacting Window:  

If your window sill won’t open because it’s swollen shut, then something is causing the humid weather around your home to rise. Check to see if you leak into your wall or ceiling, as this could be the culprit. It also possible that the cold weather is the reason for manual window replacement.

10.Window Isn’t Centered:    

If you look at your window and notice that it is tilted or left or right, this can cause a problem. If the window isn’t centered properly in its frame, it won’t be easy to open and close. Think of how difficult it would be to open and close your front door if it weren’t centered on the jam perfectly.

Why It’s Important to Fix a Window That Got Stuck?

Stuck windows can be annoying, but this problem is often a sign of other issues. Think about it this way: if your complete window was working properly and then it stopped rolling down, wouldn’t you get it fixed right away? The same logic applies here. If you know how to fix a stuck window, those small jobs should be easy to repair.

If it’s more complicated than that, then you should call a professional to help you out. Given the expense of having a professional come by and do the work for you, that stuck window may be worth repairing yourself if they’re on older windows. The materials are often inexpensive, so there isn’t really any reason not to at least try to fix the issue yourself.

Methods on How to Close a Stuck Window: 

Method 1: Un-Jam the Window

If the window is just stuck, you can usually fix it by opening and closing the window repeatedly. This should cause it to “break-in” so that it opens and closes more smoothly from then on out. It would help if you also cleaned the window tracks on the side of your window. They usually collect dust and refuse to let the window pass through smoothly over time. 

This method can be used with any stuck window, such as a door or even elevator doors that get caught in place sometimes. Repeating this process several times will help you break the window out of its “rut” and make it easier to open again.

Method 2: Lubricate the Hinges

You can also use WD-40 or a bar of soap to help lubricate the hinges on your window, door, etc. If you have any lubricant handy and it seems to be stuck, just put a little bit in and around the metal hinges so it will slide more easily. The soap is best for windows as the lubricating grease does not attract dust, etc., and it will leave a film on your window that may be able to help prevent it from becoming stuck again.

You can lubricate the track using a non-petroleum-based lubricant. WD-40 is probably your best bet. It would be best to spray the lube on a rag or towel first and then wipe it along the track, which will help to disperse it evenly across the surface.

Use Vacuum Cleaner

Method 3: Blow Out the Hinges

If you have a hairdryer or any powerful fan, use this to dry or heat the gun. Then, you can use that to get the window unstuck. First, find a way to prop up the window at an angle (so it is tilted upward).

Next, please turn on your hairdryer and aim it toward the hinges of the stuck window. As the hot air blows out of the blow dryer into this small opening, it will create a vacuum and suck the window away from the wall. This may help to un-stick your window if it is just stuck. 

Method 4: Use a Putty Knife or Other Flat Tool

If you have a flat putty knife lying around, use this to try and pry or wedge between the window panes to un-stick them. This method may work best if you apply a little bit of pressure so that the top part of the window can lift enough for you to make more space at the top. This way, you might be able to slide it up with utility knife and off the window frame so that it can rest against the wall again.

Method 5: Break-in Your Window for Smooth Operation

If all else fails, consider breaking in your window by using a hammer or chisel to break away part of the jamb (the framing that holds the window in place). This will give you enough space to slide the window up and down without dealing with it getting stuck.

While this may not be a good idea, as your window may work perfectly fine if you break out all the parts of the jamb frame, but then again, maybe your window won’t ever close right again.

Use Hammer and Screwdriver

Try these 5 methods first and see how they work to help you unstick your window so it will easily close again. If none of them work, you may need to contact a professional to look at the problem for you. They can determine what’s causing the stuck window issue and if anything can be done to help it stay in the up position.

5 Ways To Troubleshoot a Stuck Window:

  • One way to troubleshoot a stuck window is by removing its hardware. First, take the sash and frame out completely, and then try to move it up and down again. If you notice that parts of the track or channel are damaged or missing, you should replace them with your local home improvement store.
  • When replacing these parts, be sure to place them in the correct position so that they can roll freely again. They should also be the right size for your window, so you don’t buy more than you need. 
  • Another way to troubleshoot a stuck window is by using WD-40 on the area where it is stuck. First, spray some of this lubricant on the hinge or channel, and then try to move it up and down. If that doesn’t work, then you should turn your attention toward lubricating the window’s hinges. When doing so, spray some WD-40 onto a long stream of paper towels and then wipe it over the hinges.
  • With the help of an assistant, hold the window open while you wipe away any excess oil. You’ll know that it’s working if it rolls up and down smoothly again. If not, then try to use a thicker layer. 
  • When your best efforts have failed, then you may need to replace parts of your wall or door frame as well. This is very difficult and expensive to do, so it’s better to repair that window sooner than later. You may need to purchase a new frame, track or channel if yours are damaged beyond repair. When doing so, look for parts that are as close to the original ones as you can find.

Tips and Advice To Unstick a Stuck Window

The following tips will help you get your window closed when it’s stuck in an open position. If you can’t open it, these steps will ensure that your windows are properly sealed, so they don’t leak.

Spray WD-40 On Hinge

1. Check Your Sliding Glass Door or Window to See if It’s Stuck

If your sliding door or window is stuck in the open position, then there are several things you can do to get it closed once again. First, if your frame has a slightly warped top rail, check to see if one of the rollers is touching this surface and preventing the panels from closing properly. Adjust the roller or remove any excess Windex the frame and then try closing again.

2. Adjust the Roller If There’s a Gap Between Your Door or Window Panels

The problem may be due to an out-of-adjustment roller. A loose roller will prevent your glass from gliding effortlessly over it, causing it to get stuck in place once it reaches the end of the roller. Your door or window panels should close without any gap. If a roller is too tight, adjust it using a screwdriver to turn the adjustment screw in and out until you create an even seal between each panel. Be careful not to over-tighten this screw, as you could break the assembly that holds your rollers together if they are made of plastic.

3. Remove Excess Windex Between Panes of Glass

If your window is still stuck in place, you may need to clean off the excess Windex that prevents it from closing properly. Removing this sticky substance will ensure no obstructions between panels, and your door or window can glide effortlessly over the rollers. If you don’t have a Windex solution handy, try spraying plain water between panels until they are clean of debris and glue.

4. Turn Off Your Air Conditioner Whenever Possible to Reduce Leaking

Another way of reducing leaking caused by stuck windows is to turn off your air conditioner whenever possible. This will ensure that your windows are left in a closed position. It’s hard to believe, but a cracked window will not cause as much air to leak out of your home if it is being pulled through open space instead of across your damp screen.

5. Consult with a Professional

In Some Cases, You may have tried all of the above, yet you still have a problem with your window. In this case, you will need to check with a professional to ensure that your unit runs the way it should be running. In addition, a pro will know how to adjust hardware and reconstruct parts to reduce leaking caused by trapped or stuck windows.
