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
