Replacing the screen wire in a window screen that has become damaged or torn isn’t difficult to do, though it does require an inexpensive tool called a spline roller that’s available at home improvement centers.

To replace the screen wire in a window screen:

• Remove the screen frame from the window.
• Starting from one end, use pliers to pull out the rubber spline that holds the screen in the frame.
• Remove the damaged screen wire from the frame.
• Cut a piece of new screening several inches larger than the frame.
• Press the screen wire into the groove in the frame using the convex end of a spline roller tool.
• Position the rubber spline at one corner of the frame groove, and press the spine firmly down into the groove using the concave end of the spline tool.
• Press the spline into all four sides of the screen frame groove, working any wrinkles out of the screen.
• Use a sharp utility knife to remove the excess screening even with the outer edge of the spine groove.
• Place the screen back in the window, and secure it in place.

Begin replacing a torn window screen by removing the rubber spline that holds the screen in the frame with a pair of pliers. Cut a new piece of screen an inch or so larger than the frame on all sides. Beginning in a corner, press the screen into the frame channel by pushing the spline down into it. A spline roller will be really helpful for this.

When one side is done, pull the screen tight across the frame, and press in the opposite side. Then do the same on the remaining edges, keeping out the wrinkles. Finally trim off the excess screen with a utility knife.
