- Measure the distances between posts on your existing porch to determine the size of the screen framework needed. If necessary, attach more posts using 4-by-4-lumber to fill in large gaps between existing posts.
- Create frameworks for the screens using 2-by-2-lumber. Use a router to make a groove on the outside of the framework. This will accommodate the spline rubber used to attach the screen to the framework. Paint or stain the framework to match the porch.
- Stretch screen mesh around the framework. Choose mesh appropriate to the type of insects that are common to your region. Mesh size is determined by the number of holes per square inch. Common screen mesh is 18 by 14; however, 20 by 20 will ensure that even the smallest of pests is kept at bay.
- Apply the spline rubber into the groove around the perimeter of the framework to secure the screen in place. Pull taut and trim excess mesh.
- Attach the finished framework to the porch posts using 3-inch exterior deck screws.
