Maintaining the smooth operation of your double-hung windows is essential for both functionality and aesthetic appeal. One common issue homeowners face is a faulty window spring or balance, which can cause the window to become heavy and difficult to open and close. Fortunately, replacing a double-hung window spring or fixing a window balance is a relatively straightforward task that can be accomplished with a few tools and some basic know-how.
Replacing a Double Hung Window Spring
Double-hung windows typically feature either rod springs or balance springs to assist with the up-and-down movement of the sashes. If you’re dealing with a window that won’t stay up or slides down on its own, the culprit is likely a damaged or worn-out spring.
To replace a double-hung window spring, follow these steps:
Remove the window sashes. Start by unlocking the window latches at the top of the frame and tilting the bottom sash inward to remove it. Repeat the process for the top sash.
Locate the balance spring. On older windows, you’ll find a metal rod with a spring inside. On newer windows, the balance spring is typically hidden within the window frame.
Release the tension on the spring. For rod springs, press down on the top of the rod to compress the spring and then unhook the bottom portion from the latch inside the frame. For balance springs, use a flathead screwdriver to turn the brake assembly 90 degrees, then raise the spring upward until the pressure is released.
Remove the old spring. Unscrew the screw at the top of the balance spring or detach the rod spring from the frame.
Install the new spring. Reverse the process to secure the new spring in place, making sure to align the tension on both sides of the window.
Reinstall the window sashes. Carefully place the sashes back into the frame, ensuring they latch properly.
Fixing a Double Hung Window Balance
In addition to replacing a faulty spring, you may also need to address issues with the window balance, which is responsible for counteracting the weight of the sashes and allowing them to move up and down smoothly.
To fix a double-hung window balance, follow these steps:
Remove the window sashes, following the same process as in the previous section.
Locate the window balance. This is typically a spring-loaded cartridge or mechanism hidden within the window frame.
Inspect the balance. If one or both sides are broken or dislodged, you’ll need to replace the balance.
Install the new balance. Secure the replacement balance in the frame, making sure it’s properly aligned and tensioned.
Reinstall the window sashes. Carefully place the sashes back into the frame, ensuring they latch properly.
By following these steps, you can effectively replace a double-hung window spring or fix a window balance, restoring the smooth operation of your windows and maintaining the overall appearance and functionality of your home.
