How to Repair Window Screens

Badly ripped window screens should be replaced, but most small tears can be easily repaired.

To make your own patch for nylon or fiberglass screens, cut a patch just barely larger than the hole. Apply a thin layer of fast-drying glue along the edges of the patch, and press it in place. To avoid sticking fingers to glue, use low-tack painter's tape to hold the screen together as it dries; cut a piece of tape larger than the patch, gently tape it to the patch, and leave until dry. To make your own patch for a metal screen, cut a patch from a length of screening. Trim edges of the hole into a neat square opening. Make sure the patch is 1/2 inch larger all around than the hole to be repaired; bend edges' teeth into right angles. Set patch over opening so teeth penetrate the screen. Turn screen over; bend teeth flat on other side to hold in place.

The screening is typically held in place with staples, which are hidden by molding. Pry up the existing molding with a small chisel or screwdriver, and remove the old screening. Cut replacement screening with shears to overlap frame by half an inch all the way around, and set in place. Use staple gun to fasten screen, working from the middle of opposite sides to the corners, keeping tension even.

Nail the molding back into place with small nails or brads, and countersink. Trim excess screening with a utility knife. Fill nail holes with paintable wood filler, and paint.

Cut replacement screening with shears, and position so that it overlaps the channel. "Prime" the screening, unless it is synthetic, by pressing it into the channel along the top of the frame using the convex end of a spline roller, a tool similar to a blunt pizza cutter. This forms a trough for the spline. If you're using synthetic screening, which doesn't hold a shape, simply proceed to step three.
