Sash windows are a classic and timeless architectural feature, adding charm and character to homes of all styles. However, when these windows refuse to stay open, it can be a frustrating and inconvenient problem. Whether you’re dealing with a sash window that keeps falling shut or one that simply won’t stay up, there are several effective solutions to get your windows functioning properly again.
Diagnosing the Issue
The first step in fixing a sash window that won’t stay open is to determine the root cause of the problem. There are a few common reasons why a sash window might not stay up:
Disconnected or misaligned balance shoes: The balance shoes are the components that connect the sash to the window’s counterbalance system, allowing the sash to move up and down smoothly. If these shoes become disconnected or out of alignment, the sash will not stay in place.
Broken or damaged balances: The balances, which are the counterweights that help the sash stay open, can become worn out or broken over time, causing the sash to fall shut.
Bent or damaged pivot bar: The pivot bar is the small metal bar that attaches the bottom of the sash to the balance shoe. If this component is deformed, it can prevent the sash from staying in place.
Cracked or crushed balance shoe: The balance shoe, the component that the pivot bar connects to, can become damaged, leading to issues with the sash staying open.
Fixing a Sash Window That Won’t Stay Open
Once you’ve identified the root cause of the problem, you can begin the process of fixing your sash window. Here are the steps to follow:
Step 1: Remove the Sash
The first step in repairing a sash window is to remove the sash from the frame. This will give you better access to the internal components and allow you to inspect them more closely. To remove the sash, use a screwdriver to take off the stops inside the window frame, then pull the sash toward you to remove it from the slot.
Step 2: Check the Pivot Bar
Examine the pivot bar at the bottom of the sash. If it is bent or broken, you’ll need to replace it with a new one. This is a relatively simple fix, as the pivot bar is a small, inexpensive component that can be easily swapped out.
Step 3: Inspect the Balance Shoes
Look at the balance shoes, the components that connect the sash to the window’s counterbalance system. If the shoes are disconnected, crushed, or out of alignment, you’ll need to reposition or replace them. Use a screwdriver to gently guide the shoes back into their proper position, making sure the tilt pin at the bottom of the sash is securely engaged with the shoe.
Step 4: Check the Balances
Examine the balances, the counterweights that help the sash stay open. If they are broken or damaged, you’ll need to replace them. Balances come in different types, such as spiral, block and tackle, and constant force, so be sure to get the correct replacement parts for your specific window.
Step 5: Reassemble and Test
Once you’ve addressed any issues with the pivot bar, balance shoes, and balances, reassemble the sash and reinstall it into the window frame. Slide the sash up and down a few times to ensure it’s moving smoothly and staying in place as expected.
If you’re still having trouble getting your sash window to stay open, there’s one more trick you can try:
A Simple Hack to Keep a Sash Window Open
If all else fails, you can use a simple device called a “sash drop” to keep your sash window open. A sash drop is a small, L-shaped piece of metal or plastic that you can pivot into position to prop open the bottom sash. When the window is open, you simply pivot the sash drop into place, and the bottom sash rests on it, keeping the window open.
Sash drops are an inexpensive and easy-to-install solution, and they can be a lifesaver if you’re dealing with a stubborn sash window that just won’t stay up. You can find sash drops at most hardware stores or online, and they’re a quick and easy fix that doesn’t require any major repairs.
Maintaining and repairing sash windows can be a bit of a learning curve, but with the right tools and a little bit of patience, you can get your windows functioning like new again. Whether you need to replace a pivot bar, realign the balance shoes, or install a sash drop, taking the time to address the issue will ensure your sash windows continue to operate smoothly and add charm to your home for years to come.
