Clock Spring Balances: A Guide to Home Window Repair

Windows play a crucial role in enhancing the aesthetics and functionality of our homes. However, over time, wear and tear can take a toll on various components, affecting their performance. One common issue that homeowners encounter is problems with window balances. In this article, we'll focus on clock spring balances, discussing what they are and how to repair them to restore your windows to optimal functionality.

Understanding Clock Spring Balances

Clock spring balances are mechanisms used in double-hung windows to counterbalance the sash weight, making it easier to open and close the window. They consist of a coil of spring steel housed in a metal or plastic case. When the window is opened, the spring is tensioned, and when closed, the tension is released, helping to keep the window in place.

Common Issues with Clock Spring Balances

Several issues can arise with clock spring balances, leading to window operation problems. Some common issues include:

Broken Springs:

Over time, the clock springs may wear out or break, reducing their ability to counterbalance the window sash effectively.



Misaligned Springs:

Misalignment can occur due to various reasons, causing uneven tension and hindering smooth window operation.



Rust and Corrosion:

Exposure to the elements can lead to rust and corrosion on the clock spring balance components, affecting their performance.



Repairing Clock Spring Balances

 Identify the Problem:

Before starting the repair, carefully examine the window and identify the specific issue with the clock spring balances. This will help you determine the appropriate course of action.

Remove the Window Sash:

In most cases, you'll need to remove the window sash to access the clock spring balances. Follow the manufacturer's instructions for your particular window type.

 Locate the Clock Spring Balances:

Once the sash is removed, locate the clock spring balances on either side of the window frame. Inspect them for any visible damage or misalignment.
