How to Operate Double Hung Windows

Double hung windows are designed so that the top and bottom windows can be removed one at a time or separately without removing or operating the other. You may need to operate double hung windows to clean them or replace the glass.


  1. Locate the double hung window you want to operate and stand in front of it as if you are looking out the window.

  2. Look on the bottom window sash to find the sash locks. They should be located on the top ledge of the bottom sash.

  3. Lift the window up a few inches. To do this, crab the bottom of the window and push it directly up.

  4. Find the window locks and look for two sash latches located next to them. Place both hands on the latches and use your finger to push them both at the same time.

  5. Grab the top window sash and pull it down towards you. Allow the top part of the sash to come away from the window and the bottom portion to remain inside the window frame.

  6. Put the bottom window back into the frame and listen for it to click. The click will mean the window is secure.

  7. Grab the top sash with your hands and pull it straight down towards. As the top sash comes down, the bottom sash should stay securely in place.

  8. Replace the top window and listen for the click sounds to know it is being held in place securely.
