How to Fix a Window That Won’t Close All the Way

| September 16, 2024

Wondering how to fix a window that won’t close all the way? We’ve all been there at least once! That’s why we’ve already done the research and found all possible causes, so read on to discover causes and solutions!

Key Takeaways

  • Common reasons for windows not closing properly include dust and debris build-up, shifted foundations, warped frames, moisture-damaged frames, and loose or broken hardware.
  • If a double-hung window doesn’t close all the way, there may be an issue with the shoes or the balance springs. If it’s a casement window, check the crank mechanism, the hinges, and whether the sash is sagged. In the case of sliding windows, you should pay attention to the tracks and the roller system.
  • Wood windows that don’t close properly may be moisture-damaged or rotten. There may also be paint or varnish accumulation that blocks some of its components. You may have to clean the windows, remove the paint, allow them to dry, and refinish them.
  • Contact Magic to install crank-less and hinge-less replacement windows that require little to no maintenance.

Why Isn’t My Window Closing All the Way?

There are several common reasons why you may be dealing with a stuck window, including:

  • Obstructions in the window track. This occurs if the windows are not cleaned and maintained regularly. Dust, debris, and paint can accumulate between window components, which affects window operation.
  • Locked windows. Sounds too easy? It’s more common than you’d think! Sometimes the latch is just slightly engaged, so when you’re trying to close the window, it just won’t!
  • Shifting foundation. The foundation of a house moves over the years. These shifts can affect the alignment of your window frames. In this case, you’ll have to contact a professional to assess the foundation. Once the issues are fixed (if they’re fixable), you can replace the windows.
  • Warped windows. Window warping is most common in vinyl windows. If vinyl windows are constantly exposed to direct sunlight or extremely cold weather, they will warp and crack over time. When a window is warped, it does not have the same shape anymore, so naturally, it won’t operate as needed, and you may not be able to close it fully. In this case, you’ll probably have to replace the windows.
  • Moisture-damaged windows. This problem is commonly seen in wood windows. Wood naturally absorbs and retains moisture, which leads to warping and rotting. You’ve probably seen at least once a swollen timber window that can’t be closed, right? Well, if that’s the case with your windows, it’s caused by moisture damage.
  • Damaged or worn-out window hardware. A window is like machinery consisting of multiple parts. If one component stops working, the machinery can’t function at its best. So, if a window component is worn out or damaged, you may not be able to close the window all the way. It’s similar to a car – if the window motor or the window switch stop functioning properly, you’ll have to deal with a stuck car window.

How to Fix Windows that Won’t Close?

If you can’t get your window closed, here are some steps to follow to fix the problem regardless of what window type or material you’re dealing with:

  • Vacuum and clean all window components in-depth.
  • Lubricate window tracks and other components if needed. Don’t forget to use cleaning solutions and lubricants that are safe for your window.
  • Tighten all loose fasteners and screws. If you notice any sash misalignments, adjust the screws of the hinge arm on casement windows or the balance system on double-hung windows.
  • Replace the locking mechanism if it’s broken.
  • Inspect the window frame for visible gaps, cracks, and drafts. You may have to replace weatherstripping or caulking. If you notice large gaps caused by window frame shifts, contact an expert.
  • Inspect window hardware and check if any components are worn out or damaged.
  • If you find any broken components, check if the repairs can be covered by the warranty. If they’re not, replace them yourself or call an expert.

If these steps didn’t help, keep reading to learn more about issues specific to various window types and materials.

Why Is My Double-Hung Window Not Closing?

If you’ve noticed that your double-hung windows don’t close all the way, here’s what may be causing this:

  • There may be an issue with lock alignment, especially if you haven’t used the window locks in a while. To fix this, push the top sash up to ensure it’s fixed within the frame, then push the bottom sash down to ensure it’s fixed within the frame. This way, the locks become properly aligned, the sashes are fixed within the frame, and you can close and lock the window.
  • There may be an issue with the balance springs or the window sash channels. You can adjust or replace these by following relevant step-by-step guides.
  • The window shoe gets stuck at the bottom of the frame. If you lift the bottom sash and notice it has come out of the shoe, the latter being stuck at the bottom, that’s your answer. The stuck shoe prevents your window from closing properly. Use a flat screwdriver to fix this. Insert it into the shoe, and without removing it, slowly rotate the screwdriver and lift the shoe until it’s in the U shape. Push the sash down into the shoe, and voila! Problem fixed.

How to Fix A Casement Window that Won’t Close All the Way?

Here are the most common reasons behind casement windows not closing all the way:

  • The crank handle or the whole crank mechanism may be broken. In this case, you’ll have to replace it. If you’re unsure how to do this, it’s best to call a professional.
  • The hinge arms can be stuck, damaged, or misaligned. You may have to remove the sash to check the hinge arms and find the problem. Only then will you be able to find a solution. You may need to adjust the hinge arms or replace them.
  • There may be dust and debris stuck on the outside of the window that prevents it from closing properly.
  • The window sash may be sagged. This problem is more common than you’d think because of the opening mechanism of casement windows. Since the opening occurs only from the bottom, and the top of the sash basically follows this movement, the sash sags over time. This can lead to window functionality issues. Sash sagging may also occur if the window frame is not square or the foundation has shifted. Sometimes, you can fix this sagging issue by adjusting the hinge channel. In other cases, you’ll have to replace your casement windows.

How to Fix A Sliding Window that Won’t Close?

Sliding windows have a much simpler opening mechanism and design compared to casement or double-hung windows. They usually don’t close all the way if the tracks are filled with dirt that blocks the window’s path, if there’s an issue with the rollers, or if there’s a problem with the locking mechanism.

To fix these, vacuum and clean the window thoroughly. Then, lubricate the tracks using a product that’s safe for your windows.

If you think there’s an issue with the rollers, you’ll have to remove the sash and check them. Sometimes there’s dirt trapped between the rollers, and all you have to do is clean them. Other times, you’ll have to replace them. If the locking mechanism is broken, you’ll have to replace it.

How to Fix a Wood Window that Won’t Close All the Way?

While aluminum and vinyl windows, for example, can usually be fixed using the tips above, wood windows can have other issues that prevent them from closing properly:

  • Paint or varnish build-up. As you probably already know, wood windows require regular maintenance. They need to be refinished every few years, depending on what products you use and their quality. As time passes, paint flakes and peels, and pieces of it can get stuck between window components, affecting its smooth operation. Try cleaning and vacuuming the windows thoroughly and use a paint scraper or a utility knife to remove the excess paint.
  • Broken pulleys. Pulleys are small wheels installed on the sides of a double-hung window that plays an essential role in its operation. Today, pulleys aren’t as widely used as before. They’re now replaced by spring balances. Pulleys are usually found only in old wood windows or renovated older buildings where homeowners want to preserve the original window design. When the pulley is broken, the mechanism fails to hold the sash when you’re closing it, which is quite dangerous because the glass can break. If you find suitable pulleys, you can replace them. Otherwise, you’ll have to replace the entire window.
  • Moisture damage. If the windows are swollen, there’s clearly a moisture issue. You can remove the paint to allow the wood to dry quickly and evenly. This can take a few days or a week. Once the wood is dry, use a sandpaper to sand the swollen area, and then use paint or varnish to refinish the windows. Keep in mind that severe moisture damage requires professional evaluation.

Vertical sliding windows won’t close all the way? Here’s why!

If you can’t close your vertical sliding windows, there may be dust or debris build-up between the components, the hardware may be worn out or damaged, there may be an issue with window springs or lock alignment, or one of the shoes may be stuck at the bottom.

How often should I clean my window tracks?

You should clean your window tracks regularly to prevent dust and debris build-up, which can cause the window to get stuck.

Can I fix warped wood myself?

You can fix minor warped wood by removing the paint, allowing it to dry (if the issue is caused by moisture), then repaint it. However, it’s best to seek professional help for severe warping.

What tools do I need to adjust a window sash?

You’ll need a screwdriver to adjust the alignment screws on the window sash. This is the most common tool for this task.

When should I call a professional for window repairs?
