Window balances can remain in working condition longer, often 10 to 15 years old. They are however eventually prone to fail, requiring repair or replacement. This may be sudden or gradual. You would be surprised by how much harder the windows were opening than they did before. Maybe they were opening too quickly. The most common signs are that either the window sash won’t stay up or won’t open at all. These symptoms of an inefficient window balance can be noticed over a period of time, but in a different situation, it might happen suddenly one day.

Window balances are a type of window hardware that helps to keep your windows open. They work by using a spring or counterbalance to offset the weight of the window, which makes it easy to open and close. Window balances are available in a variety of styles, so you can find the perfect one for your home. Window balances work by using a coil spring and a weight to offset the weight of the window. This allows the window to open and close smoothly, without any unnecessary force.

If you have a failing window balance, and you are looking to replace it, you need to take into consideration several things including how big your windows are, the sash weight and balance constant force just to name a few. If you’re looking for a replacement balance spring for the single-hung window you should expect at least $ 150-$200 in labor or parts, but this could vary according to a couple of factors we listed earlier. Other balance types can cost way more including labor.
