How to Replace a Window Screen

To replace a torn window screen:

  1. Place the screen frame on a flat surface.
  2. Insert a small screwdriver or the point of a utility knife under the end of the rubber spline.
  3. Pry the end of the spline out and remove the spline around the frame.
  4. Remove the screen wire from the frame.
  5. Position an oversized, new piece of screen over the frame.
  6. Use the convex end of a spline roller tool to push the screen into the groove at one end of the frame.
  7. Place the spline over the groove, and use the concave end of the roller tool to push it into the groove.
  8. Pull the screen tight at the other end of the frame, and use the roller tool to push the screen and spline into the groove.
  9. Pull each of the other two sides tight and press the spline in, being careful to avoid wrinkles.
  10. Trim off excess screen with a utility knife.
