Replacing worn out or rusty window screens is one way to spruce up the look of your windows. Replacement window screens are available at home improvement centers that sell Pella products. The process of replacing the Pella window screen is slightly different between their single hung and double hung windows. Double hung windows use a full window screen, while single hung windows use a half screen. All replacement work is done from inside the home.
Double Hung Windows
Raise the lower sash to the half open position. Lower the upper sash to the half open position.
Locate the four metal lever plungers near each corner of the window screen frame. Pull the bottom lever up and the top levers down to unlock the window screen from the window frame.
Grasp the plastic finger holds at the bottom of the screen with your fingers. Push the top of the screen out while pulling the bottom of the screen into the house under the window sashes. Tilt and angle the screen as necessary to pull it through the opening.
Angle the top replacement screen through the window frame below the lower sash, holding onto to finger holds with your fingers. Pull the top of the screen back toward the window frame so that the frame sits inside the window frame track.
Push the bottom lever plungers up to lock the bottom of the screen into the frame. Push the upper lever plungers down to lock the top of the screen to the window frame.
Raise the upper sash back to the closed position and close the lower sash.
Single Hung Window
Open the lower sash to the fully open position.
Grasp the plastic screen handle at the bottom center of the screen. Lift up on the screen, and push the bottom of the screen out of the window. Pull down on the screen, and angle it to pull it through the window opening and into the room.
Grasp the replacement screen by the plastic handle and angle the screen through the window. Maneuver the top of the screen into the screen frame upper track. Push the screen up and pull the bottom of the screen into the opening.
Lower the screen until the handle snaps into the bottom track. Lower the window sash.
