Window Balance Replacement Q&A

Hidden within many types of windows is a part called the balance, which is, for windows that contain them, central to operation. For windows that do have a balance, opening or closing the window without it would prove quite difficult. 

This short post will take a look at some of the questions associated with window balances, window balance replacements, and similar matters. 

But first, let’s take a closer look at something fundamental - which is, what is a window balance in the first place?

What Is a Window Balance? 

It’s all in the name “balance.” A window balance is a part hidden within the window frame that effectively serves as a counterweight to the weight of the sash - although not all window balances are weighted and some utilize springs, which provide a counterforce to the weight of the window. 

In essence, the balance is a part that offsets the weight of the sash, which makes it easier to open or close the window. 

What Types of Window Balances Are There? 

There are many different types of window balances, and recognizing this, as well as what specific type of balance your windows have, is critical before you attempt to buy and install a window balance replacement.

This is also a topic we’ve covered before, so to keep things brief: 

• Block and tackle window balances: This is one of the more common types of balances, and consists of a system of pulleys (typically one or two), a cord, and a spring. As the cord is pulled by the sash, the spring is stretched, adding tension to offset the weight of the sash. To find an appropriate window balance replacement for a block and tackle balance, you need to know the length of the metal channel, as well as the balance’s stamp.
• Spiral window balances: Spiral window balances are also very common and consist of a tube that contains a spiral shaped rod which is connected to a spring. As the sash pulls the rod out of the tube, it stretches the spring, which provides the force to offset the weight of the sash. 
• Coil spring window balances: These are a type of window balance known as a constant force balance, and consist of a coiled spring which maintains and applies the force necessary to offset the weight of the sash. 
• Clock spring window balances: Clock spring window balances are very similar to coil spring window balances except that they are a much older design and are now commonly found on older windows. They may be mounted at the sides of the window or overhead. 

In addition to these, there is another type of window balance known as a rope and pulley window balance, though this type is no longer common in most homes. It is an older style and is not more or less only found in old windows. 

How Do You Know If a Window Balance Needs to Be Replaced? 

Your window balance is not a part you should realistically be giving much thought to unless you’re wondering how to tell whether or not it’s starting to fail. That said, it shouldn’t take too much sleuthing for you to tell when your window balance is starting to go and will need to be replaced. 

Regardless of what type of window balance is actually in your windows, there are two main ways by which you’ll be able to tell if the balance is going or not. One way to tell is if it’s starting to get harder to open or close your windows - emphasis on opening, though. 

The other way to tell is if you can open your windows, but they won’t stay open and fall shut after you let them go. Another thing that might be happening is that you might open your window and it might stay open for a second or two before slamming shut unexpectedly. 

In all of these cases, the window balance is the likely culprit and you should start looking for a window balance replacement. 

Is It Hard to Replace a Window Balance? 

Fortunately, assuming you have basic tools and know what window balance replacement you need, it’s really not that hard to replace most window balances. 

First, check for stops - these are small metal or plastic parts that help retain the sash. Lift the sash, then remove the clips that secure it. As you lift, you should see the balances at the sides of the window; lift the sash until you can take it out of the frame. 

Then, you can remove the balances from their frames and set them aside. You will want to determine exactly what type of balance, and size, you have, so that you get the right window balance replacement.

Of course, this guide is non-specific and only provides the basic framework for replacing your window balance. If you’re uncomfortable with the idea of replacing your window balances, get in touch with a specialist who works with windows and doors. 

Is It Possible to Replace Channel Balances Without Removing the Window Sash? 

If you have a home with windows of such configuration that you cannot lift the sash far enough to get it out of the frame, the slightly bad news is that you probably cannot replace the channel balances without doing so - you will probably not have the clearance necessary. 

How Much Does a Window Balance Replacement Cost?

That depends on the type of window and balance you have, as well as whether you complete the repair yourself or hire a specialist to do it.

However, to give a very rough estimate - that is not binding - you can expect it to cost somewhere between $50 and $200 per window, depending on the type of balance and whether you buy the parts and do it yourself or you hire someone to do it.
