Step 1 Remove the Old Window Screen
Most window screens have a vinyl spline that holds the mesh in place. Start by removing this spline from the aluminum frame. Pry the spline out with a screwdriver and then pull it out with a pair of pliers. Check if it’s still flexible and in good shape, because if so, you can reuse it when you replace the mesh. If not, you’ll need to buy a new one. Once the spline is completely removed, you can remove the old screen.
