How to Fix a Window's Spiral Balance
If your window isn't moving properly, the spiral balance might be broken. Here's how to fix it.
A double-hung wood window typically has two sashes that move up and down. Many people nail and paint shut the upper sash. This makes it easier to seal but will make cleaning the window difficult if you cannot get at it from the outside.
If a sash will not stay up, the chain or cord connecting to the weight is probably broken. Fixing one isn't too difficult—it only takes an hour or so—but accessing the parts can be tricky. To make an older unit work more smoothly, a bit of detailed work is often required. If the window has been painted many times, you may need to scrape or even remove paint from sashes or stops in order to free the action. A balky pulley may also need to have its paint removed. Often a spray lubricant will help as well. A drafty window can be sealed by adding weatherstripping. A storm window will help greatly as well. Newer windows have a variety of mechanisms to keep sashes up when raised.
