   • Worn or damaged weatherstripping can exacerbate this issue.

3. Rotten or Damaged Wood

   • Exposure to the elements can cause wood to rot, especially around the bottom of the sashes and the frame.
   • Insects and pests can also damage the wood.

   • The weights and pulleys that help balance the sashes can wear out or break.
   • This can make the windows difficult to open and close.
