Do your window screens look as though they've been through a gunfight or were attacked by wild animals? You haven't got the money or time to replace them? Don't despair. To repair holes in aluminum screens cut a patch slightly larger than the hole. Pull off one strand of wire on each side and bend remaining edge wires down. Place the patch over the hole with bent wire ends sticking through and crimp them over on the backside to hold it. For fiberglass screens, cut a slightly larger patch and place it over the hole, matching the pattern. Apply a thin bead of epoxy cement or super glue. Even clear caulk will do. Dab off any excess before it dries. You can glue aluminum screening too. It's a process of trial and a few errors. And that's the On The House tip for today.
