I have a hole in my screen. Can I repair...

You can patch small holes—those ¼” and 3/8”—with a small amount of household cement. This glue patch will be next to invisible. Larger holes up to about 3 inches in diameter in aluminum screen can usually be easily patched. A patch should go at least ½” to 1” larger all around the hole. These are either kits or just pieces of screen. Unravel a number of strands and then weave the strands through the screening and bend them tight. Plastic patches need a touch of household cement on the ends of the strands after they have been woven through.
